1.0 Safety Precautions

IMPORTANT SAFETY PRECAUTIONS. READ CAREFULLY!


9

1.1 Evacuated Tubes

1. The tip of the heat pipe can reach temperatures in excess of 392°F (200°C) when the tube is exposed to

sunlight. It is recommended that you use leather gloves when handling vacuum tubes and that you

install the tubes during cloudy days or during nighttime hours. Thick leather gloves should also be worn

when handling hot heat pipes.

2. The vacuum tubes are relatively fragile, and will break if struck by a hard object or are dropped. Care

must be taken when handling broken glass from the tubes, and wherever possible protection should be

used to prevent breakage. It is also highly recommended that you consistently be on the lookout for

broken glass in the vicinity of the collector array in the event of a storm or object falling on the

collectors.

3. If they have internal pressure built up, tubes may explode if broken rather than implode when broken.

This is an uncommon occurrence but one that should be taken into consideration.

4. In areas prone to large hail (>3/4” (20mm)), it is recommended that the collectors be mounted at an

angle 40° or greater so as to minimize the impact force

5. Always wear safety goggles when handling vacuum tubes.

1.2 Flat Plates

1. The glass panel of the flat plates is relatively fragile, and great care should be taken to ensure that no

hard objects fall onto it and cause breakage

2. When exposed to sunlight, even when empty of heat transfer fluid, the threaded fittings at the input

and output of the collector can become extremely hot. Leather gloves are recommended when

installing piping and plumbing components to the flat plates.

1.3 System

1. It is important that the system you install is fully planned out and dimensioned before installation to

avoid unforeseen and possibly dangerous circumstances as well as to have a more efficient installation.

2. Leather gloves should be worn any time when handling hot components.

3. When charged, the heat transfer fluid WILL become hot. Any leakage can cause serious scalding and

steps should be taken to make sure that the system is thoroughly sealed before charging.


10

4. It is important that use appropriate safety measures when working on a roof. Safety harnesses should

be worn at all times when installing collectors onto a pitched roof and proper footwear should be worn

to prevent slippage.

5. Do not install collectors during times of high wind velocities. Obtain approval from an engineer before

installing collectors in high wind regions.

6. Installation must be completed in accordance with relevant local standards and regulations.

7. Installation must be completed by a qualified tradesperson who holds relevant industry licenses or

certificates required that are valid during the installation.

8. Unless otherwise specified, no part of the HelioMaxx system may be inspected, repaired, maintained, or

commissioned by anyone who is not authorized personnel.

9. Always be sure that everything you do is in compliance with OSHA regulations

Make sure water tank has been depressurized. Do this by cutting off the cold water supply to the tank

and allowing the pressure to leave the system. Leaving a faucet on, for example, will accomplish this.

Make sure that the roof has full traction. If it is wet from a recent rainfall or has ice buildup you should

not be doing collector installations.

Make sure that each component of the system is present and unbroken. If anything is broken or

missing, contact SunMaxx to see what options are available to you in terms of replacement.

3.2 Positioning the Collectors

The collector is positioned in terms of its azimuth angle and inclination angle. Do not allow xcessive shading of solar system.

Azimuth angle refers to the lateral angle between true south and the perpendicular of the face of the collector. Ideally, this angle should be zero, for when the collector faces due south is receives the maximum amount of incident


13

radiation from the sun. However, due to conditions such as the direction an inclined roof faces and objects that produce shade, deviations are usually present and are usually acceptable.

In order to determine the proper azimuth angle, it is necessary to ascertain the direction of true south. True south is the direction pointing to where the sun is highest in the sky, or zenith. True south differs from magnetic south due to the fact that the magnetic poles do not precisely match up with the geographical north/south poles of the earth. Determine your magnetic declination in your region before you decide on an azimuth!

Inclination angle refers to the angle between the collector and the horizontal ground. Determining the proper inclination angle involves understanding a little bit about how the position of the zenith changes throughout the year.

The change in zenith angle is based on the fact that the axis of the earth’s rotation is tilted approximately 23.5°. Because of this, the maximum zenith angle for any particular location is the latitude plus 23.5° (June 22), whereas the minimum zenith angle is the latitude minus 23.5° (December 22).

In order to get the best year-round solar fraction, it is recommended that the inclination of solar collectors be as

close to you latitude as possible. This represents the average of the zenith throughout the year. However, if a majority

of your heat load is during a particular time of year, it would be a good idea to adjust the inclination accordingly (less for

high summer usage and more for high winter usage). See the table below for recommended dimensions for mounting

hardware and collector spacing in order to accomplish proper inclination angles.


14

Once you have determined the required dimensions and orientation for you collectors and mounting

hardware, refer to the our guide on roof mounting.

4.0 Main Components in HelioMaxx Systems: There are a variety of HelioMaxx Prepackaged systems to meet almost any domestic situation you may have. The

component list is shown below (keep in mind not every component is available in every kit).

4.3 UniMaxx Pump Station

The pump station is the enclosure that contains the flow meter, pressure gauge, variable speed pump, pressure relief

valve, piping connection to the expansion tank, manual air separator, and the controller itself. It is mounted to the wall

using an included set of hardware. It is essentially the “brain” of the entire system and controls how the system

operates.

4.4 Pre-Insulated Lineset

In order to make the piping of the solar loop much simpler, SunMaxx provides pre-insulated flexible line set in every

prepackaged kit. This line set will, with the right fittings (also included), connect directly from the tank to the pump

station and onwards from the pump station to the collectors. The line set also includes pipe hangers that meet the

requirements of support. Pipe clamps do not compress pipe insulation.

4.5 Automatic Air-Bleeder Valve

This device is placed at the uppermost point of the system and will purge the system of small air bubbles as the heat

transfer fluid circulates. This component is only present in the fitting set for the flat plate collector kits.

4.6 Expansion Tank

In times of collector stagnation (when the solar production is high and the demand is low) temperatures within the

collectors will reach very high temperatures. This causes the water in the system to evaporate and expand, creating an

increase in system pressure. The expansion tank absorbs an amount of this fluid expansion and will help to prevent the

pressure relief valve from going off. Included with the expansion tank is a specialized mounting bracket and braided

lineset.

4.7 Solar Storage Tank


17

This is where heat exchange between you collectors and potable water takes place. The StorMaxx pressurized tanks

offered by SunMaxx provide an internalized heat exchanger, so all that necessary is to affix the linesets from the solar

loop to the designated inlet and outlet of the tank. It also has an inlet and outlet for use in auxiliary heating, which is

necessary in virtually all systems, as well as an additional opening for recirculation.

4.8 Other Components

HelioMaxx Prepackaged kits come with 3 temperature sensors, one of which is a high temperature resistant sensor.

These are used to measure the temperatures at various points in the system and send the data back to the controller,

which reacts according to the data it receives.

4.9 Mounting Kits

These kits include the hardware necessary to mount your collector(s) to the roof. Depending on the amount of

collectors and preferred mounting style, your kit may have differing mounting hardware. This manual does not cover

manual mounting installation, however, so refer to the appropriate document when attempting to mount a collector.

5.0 The Pump Station All connections are pre- assembled by the manufacturer. Check for leaks when commissioning

the station (pressure test).

5.1 and 5.2 Mounting the Pump Station and Expansion Tank

1. Determine where to mount the pump station; remember to include space for the expansion vessel!

2. Take the complete station out of the packing.

3. Remove the front half of the insulation by pulling it. The thermometers loosen from the ball valves. Do not

unscrew the pump station from the back part of the insulation!

4. Mark the fastening holes and drill holes; insert the enclosed dowels.


18

5. Fasten the complete pump station with the wall mounting bracket to the wall (depending on the pump version,

upper or lower holes in the insulated casing) and tighten the screws. For this purpose, use a positive cross-

recessed screwdriver!

Wall Mounting:

1. Determine where to mount the pump station. Be sure that it is easily accessible and does not interfere with any

other machinery. Keep in mind you will need to leave space for the expansion vessel.

2. Take the pump station out of its packaging. Remove the front half of the insulation by pulling it. The thermometers

loosen from the ball valves.


19

3. Mark the fastening holes on the wall and drill the holes. Insert the enclosed dowels.

4. Fasten the complete pump station with the wall mounting bracket to the wall (depending on the pump version, upper

or lower holes in the insulated casing) and tighten the screws. For this purpose, use a positive cross-recessed

screwdriver.

5. The default settings on your controller are most likely valid and will allow your system to function efficiently. If you

wish to engage in any reprogramming, it is highly recommended that you read the product manual for the controller.

5. Attach the mounting bracket to the expansion tank

to the wall at least 6 inches away from the pump

station using the ¼” mounting screws provided. It can

be mounted with the bracket facing up or down.

Connect the expansion tank to bracket using the ¾”

union provided in the expansion tank hardware. This

union attaches directly to the braided expansion tank

lineset which subsequently attaches to the designated

port on the pump station.

6.0 Piping

6.1 Overall Diagram

The fully assembled and piped system should follow the guidelines of the diagram below:

6.2 Collector Fittings

6.2.1 Flat Plate Fittings

The fittings of SunMaxx TitanPower Flat Plate collectors are ¾” BSP threading. The fittings on the left side of the

collector are male, whereas the fittings on the right side are female.

Female Fitting

Male Fitting

Depending on how you pipe your collectors, the inlet and outlet can be on either side of the collector. Just keep in

mind that the outlet must always be on the top port and the inlet must always be on the corner diagonal from the

it. See below:

1. At the outlet of the flat plate collector, attach the ConnectMaxx-TPPSU2 as shown below. Be sure that you place

a carbon gasket between the components to maximize the seal. NOTE: The outlet of the collector is always at the

Male

Female


23

top!

2. Seal off every unused port of the flat plate using a brass cap and a carbon gasket.

At the outlet at the top of the flat plate, you will attach a manual air bleeder valve. Be sure to use a carbon gasket

when installing the manual air bleeder valve assembly

Caps must be attached to each open fitting of a flat plate collector. Likewise, a carbon gasket must be inserted in

order to maintain a proper seal.


24

6.2.2 Flat Plates in Array

In order to have multiple collectors in the same solar loop, it is necessary to mount the collectors as an array.

Because the Collectors have both male and female fittings, it is possible to simple attach one to the other.

You must use a carbon gasket ring for the connection, however.


25

6.3 Vacuum Tubes

6.4 6.3.1Vacuum Tube Fittings

The outlets and inlets of a SunMaxx ThermoPower VHP collector are both 1” NPT male nipples. All that is needed to

allow for them to be compatible with the lineset is a simple 1” to ¾” reducer.

6.3.2 Vacuum Tubes in Array

When Mounting Several VHP collectors in series, all that is necessary is a 1” union.


26

6.4 Pressurized Storage Tank

When installing the pressurized storage tank, be sure that it is level and stable, and that all of the ports are easily

accessible. The StorMaxx Pressurized storage tanks have ¾” NPT nipples for the inlet and outlet of the solar loop,

indicated below. 1” NPT Male are used for the domestic loop.

At the Inlet and outlet of the solar heat exchanger in the tank, attach a ball isolation valve.

Insert the gray pt1000 sensor into the sensor port in

the lower portion of your tank. Attach the wire leads

into the S2 terminals on the controller.

For the relay to the pump, wire the 115v line to the terminals labeled lead/ground/neutral. Only strip a

Solar Loop

Inlet/Outlet


27

6.5 Preparing the FlowMaxx Lineset

Based on the piping diagram, you will need four lengths of insulated piping. 2 will lead from the pump station to the

StorMaxx pressurized tank, where the other 2 will be the supply and return leading from the pump station to the

collectors. Determine the necessary lengths for each section and cut them using a hacksaw. Be sure to cut to at least 1-

2 feet longer than is necessary, for it is better to have a little slack in the line than to fall short.

To complete the piping of your system, it is now necessary to connect every component together using the FlowMaxx

Insulated line sets provided. The ends of the linesets should all have male fittings, and if you have attached all the

adapters for the rest of the components correctly, everything else should have female fittings.

*All Penetrations through fire-rated assemblies should not reduce fire resistance below code.*

Remove the fitting and slug. The end of the

corrugated line set should now be flattened and

ready to be fitted.

Reattach the fitting to the nut, inserting a graphite

washer between it and the nut.

Repeat this process for each end of the lineset. Keep in mind that each span of lineset will have a male fitting

at one end, and a female fitting at the other. This procedure only illustrates the male fitting, but the

procedure for the female fitting utilizes the same process albeit with a different apearance.

6.4.2 Roof Penetrations *Do not impair enclosure function or allow vermin intrusion

6.4.2a Roof Hooks * Structural members penetrated by solar system components must meet code

The roof hooks meet applicable codes and NRCA and represent an essential component of our universal roof mounting

hardware. Whether you are installing flat plates or vacuum tubes you will need to utilize these roof hooks to properly

mount your collectors.

If installed correctly, the roof hook flashing system provided by SunMaxx…

azimuth angles

Will not cause excessive shading of

other collectors in array

Will not compress insulation

Will not reduce fire resistance below

code

Will isolate roof and construction

materials from the high temperatures

generated by the collector array.

Before you begin, it is important that you are well aware of the required spacing between the mounting feet as well as

their locations on the roof. The feet will be bolted directly in to the rafters, so it will also be necessary to locate where

the rafters lie. One way to do this is to locate the rafter overhang at the side of the house and mark out the rafter’s path

on the roof using chalk. Another is to locate an eyebrow vent on the roof and measure off its center equally in both

directions. It is also possible to find rafters using a density meter. During frosty conditions the rafter’s perimeters will be

visible from the roof. If all else fails, you’ll have to go into the attic. For instructions on mounting the roof hooks, read

the procedure below:

1.The solar hook fastens directly into a rafter without the need to pre-drill any holes. The first bolt to be screwed in

should be the one with the elongated hole, as this will allow for easier vertical alignment


31

2. Slide the tail of the flashing under the head lap of the roofing material directly above the installed mount and rotate

the flashing down so that its final position is centered horizontally. Fasten the flashing to the roof using NRCA approved

roof sealant.


32

3. It may be necessary to cut out sections of

overlapping tile to make room for the flashing. Use a

utility knife or equivalent to accomplish this.

3. Repeat this process for all of the mounting feel

required. Make sure that the horizontal spacing

between the feet is less than the length of the

mounting rail. If you are flush mounting, the vertical

spacing is already determined, but if you are utilizing a

tilt mount, it will be necessary t o pre-assemble the

collector mounting frame and record down the spacing

required for the back leg to be perpendicular to the

roof.

4. Depending on the type of kit you have and the roof

layout you have available

*Building material adjacent to solar components will not be exposed to elevated temperatures

7.0 Configuring the Controller

7.1 Sensors and Wiring

Insert the Black pt1000 sensor into the supply side of your last collector in series using the sensor wells built in to the

collector. Attach the wire leads into the S1 terminals on the controller. This sensor wire should be routed through the

pre-insulated lineset alongside the piping.


33

For ThermoPower Vacuum Tube Collectors, locate the sensor port on the side of the manifold and directly insert the

high temperature sensor with a generous amount of adhesive sealant.

For the SunMaxx TitanPower Collectors, you will use the sensor housing included with the flat plate fitting assembly.

Insert the sensor through the fitting cap and then into the housing, screwing the fitting cap into place and securing the

sensor in place.


34

Insert the gray pt1000 sensor into the sensor port in

the lower portion of your tank. Attach the wire leads

into the S2 terminals on the controller.

For the relay to the pump, wire the 115v line to the terminals labeled lead/ground/neutral. Only strip a short part

of the sheathing (less than ½ in) to minimize loose wiring.

7.2 Programming the Controller

The default settings on your controller are most likely valid and will allow your system to function efficiently. If you wish

to engage in any reprogramming, it is highly recommended that you read the product manual for the controller included

or contact our engineering/technical support department.

8.0 Charging the System

8.1 Pressurizing the System

8.1.1 Determining System Pressure

The overall pressure of the system should be between 17-90 psi. The pressure of your system will not necessarily affect

its performance, but a general rule of thumb in determining a good system pressure (in psi) is to take the vertical height

of your system (in feet), divide it by 2.31, and add 15.

8.1.1 Pressurizing with Air

A compressor with at least ½ hp should be used to pressurize the system with air.

1. Attach a Schrader valve to the female end of a standard garden hose to allow it to fit into the fill valve of your pump

station. Close the drain valve.

2. Activate the compressor. Observe the pressure gauge on the pump station and make sure that the pressure is

increasing.


35

3. Deactivate the pump and seal off the system and observe the pressure gauge on the pump station. If the pressure

remains constant for around 10 minutes, your system is most likely leak free. If the pressure falls search for leaks

around the piping. A trick to doing this is to lather all joints and fittings with soapy water. If there is a leak at that

location the soap will bubble.

4. Depressurize the system by depressing the Schrader valve

8.2 Flushing the System

Flushing involves running water into the fill valve and having it circulate around the system before being expelled at the drain valve. It is recommended that you use the SunMaxx filling station to do this. Flushing removes any existing fluid and loose particulates that can otherwise cause stress to the system over time. Be sure the water flowing out of the drain valve is contained in a proper receptacle (such as a 5gal barrel)

Another application of flushing is closing the drain valve and allowing the system to fill. When it is full and the pressure gauge starts to increase, deactivate the filling station and let the water drain into a receptacle. By measuring the amount of water in said receptacle, the overall system volume can be determined.

8.3 Preparing the Heat Transfer Fluid

In most situations it is necessary to use a 40-50 percent mixture of glycol and water as your heat transfer fluid. The

addition of glycol is meant to prevent freezing, which has the potential to seriously damage the system. Based on the

volume you determined from flushing, create the appropriate mixture. It is advisable to make an extra 10-20 percent of

the solution as to ensure there will be no shortage of fluid. Place the mixture into the SunMaxx fill station.

8.4 Filling the System

1. Close the Butterfly valve between the fill and drain valves with a flat head screwdriver.

2. Connect the return hose from the SunMaxx fill station to the filling valve of the pump station, and the supply hose to

the drain valve.

3. Activate the fill station. The fluid being supplied to the system will circulate and exit at the drain valve, where it will

reenter the fill station. Continue allowing the pump to circulate the fluid until the fluid coming out of the drain valve

ceases to bubble.

4. When the bubbling ceases, close the drain valve while leaving the pump on. Continue to fill the system until the

pressure gauge reaches the pressure level you determined earlier. At which point, close the filling valve and quickly

open the butterfly valve.

5. Activate the solar pump to ensure the system is running.


36

8.5 Inserting the Vacuum Tubes

Note: Inserting the tubes should be the last step in installing and commissioning a vacuum heat pipe collector system.

Slide the heat pipe approximately 6 inches out from the glass tube and aluminum fin. Then, insert the bulb of the

heat pipe into the manifold. To insert the glass tube, Apply lubricant to the end of the glass tube, as it will make

insertion much easier and breakage less likely. Once the glass tube is in place, affix the rubber gasket to the manifold

by slipping it over the tube.


37

9.0 Performance Assessment

After the system has been installed, it is important that you make sure that it is performing as well as it was expected to.

It is better to find errors right away than to find them on your next fuel bill.

To properly assess the performance of your system, follow the steps below:

9.1 Starting Tank Temperature

Record the starting temperature of your tank as seen on the controller. Write this number down, as it will be necessary

for future calculations.

9.2 Determining Solar Potential

Determine the solar potential for your area. You can do this by downloading RETscreen4: http://www.retscreen.net

1.Find the closest location in the database. Write down the insolation data for the month you are installing the system.

2.Multiply that number by 317.1 to convert to btu/ft2/hr.

3.Multiply that product by the total number of square feet of absorber (one tube equal 1 ft²)

4.Multiply this number by the efficiency of the tubes (.73) or the efficiency of the flat plates(.7)

5.This product should be the total btu’s produced by your system per day if mounted to ideal conditions

6.Reduce by 10% if mounting is more than 30 degrees of appropriate incline angle.

7.Reduce by 10% if mounting is more than 15 degrees off of true south.

9.3 Determine Collector Array Yield

1.At the end of the day, record the temperature of your tank. Find the difference between this temperature and the

starting temperature. This is the temperature differential.

http://www.retscreen.net/#_blank


38

2.Multiply this differential (heat gain) by gallons of storage and multiply that by 8.3. This number represents BTU

production yielded by collector array during that solar day.

9.4 Determine Heat Transfer Across Collector Array

Compare temperature difference from collector inlet temp and collector supply temp. There should be a 4-7 degrees

difference per collector.

9.5 Determine the Heat Transfer Across Collector Array

Determine the difference in temp across the exchanger. This should equal the temperature gain across collector. Adjust

flow rate accordingly with isolation valve or pump speed to compensate for inconsistencies

10.0 Operations and Maintenance

10.1 Measuring Glycol Concentration

Each year it is important to make sure the concentration is consistent with manufacturer’s recommendation to ensure

the warranty is upheld. Use a spectrometer or hydrometer to gain accurate results.

10.2 Measuring Glycol Acidity

Measure the acidity of the glycol by use a pH kit or digital pH tester and measure the pH of the glycol loop. Be sure the

reading falls between 7.0-8.8.

10.3 System pressure

Ensure that the system is still operating at the target pressure set at step 8.1.1

10.4 Piping Insulation

As time goes by and the system is exposed to more and more contact with external sources, the insulation of the various

components of your system, most notably the piping, will depreciate. It is recommended that you check periodically to

ensure that the insulation is still affixed in its proper location and is free of holes and tears.

10.5 Inspection of broken tubes (Vacuum Tube Systems Only)

The vacuum tubes on the roof are susceptible to damage over time from various environmental and physical elements.

A quick periodic check from ground level to make sure that the tubes aren't broken is recommended.

The tubes are also at risk of losing their vacuum seals. This can easily be inspected for by checking the base of the tubes.

If a white powdery substance is present in the tube, the seal is compromised and the tube will need to be replaced.


39

10.6 Cleaning the Collectors

Over time the collectors can accumulate buildup of sediment and dust particles that will cause the system to lose

efficiency. It is a good idea, therefor; to clean off the collectors on a regular basis (annually is recommended).

10.7 System Commissioning and Maintenance

Follow these guidelines in order to properly commission your system.

1) Safety First

a) OSHA standards must be observed and practiced

i) http://www.osha.gov/index.html

a. When handling Glass you must wear protective eye wear and gloves

2) Pressurizing Line Set

a) With air compressor

i) Using an air compressor of ½ hp pump, you must first pressurize the system, not exceeding 90 psi. Visually

inspect lines for leaks, watch pressure gauge.

ii) convert a hose thread female fitting with a schrader valve that will allow you to connect your compressor to

the fill port. Be sure all valves are closed that would allow air to escape.

b) Determine the system pressure-

i) Your system will function between 17-85 psi. Pressure will not affect the collector performance but should not

exceed 85 psi.

ii) To find the proper pressure for your system take the total vertical height and divide by 2.31 and then add 15

psi to that. The result will be your target pressure. Do this before charging your system and remember your

target pressure. Typically, the average domestic hot water system is set between 15-20 psig (gauge pressure)

3) Flooding and Purging

a) Mixing glycol

i) You must use a 40-50% glycol mixture (for a closed loop glycol system)in most climates north of 35N latitude.

ii) If you are using a premix solution then you can simply pump the solution in (see filling system section).

iii) If you are NOT using a premix then you must first determine the total system volume. The simplest way to

accomplish this is by filling the system with water (this helps to clean the pipes as well). Then drain the system

down and determine the total volume. You can also determine the volume that you added and subtract the

volume that comes out to find total. If you add 100% glycol to the water in the pipe it WILL mix in the loop.

b) Filtering/Flushing

i) Filter your system before closing it in commission. Small particulates can put stress on your system over time.

This can be accomplished by using the Sunmaxx solar filling station with a built in filter.

c) Filling system - The pump station has fill/drain valves above and below the pump. Between the valves is a

butterfly valve with a flat head screw. Together these make up your filling station.

i) Make sure you know what pressure you are trying to accomplish in your system for reference; See 2.b.ii.

ii) You must first close the butterfly valve with a flat head screwdriver.

http://www.osha.gov/index.html


40

iii) Open the valves and connect your hoses to each of the hose fittings.

iv) Make sure your solar filling station is full with the appropriate amount of fluid and with the correct

concentration.

v) Turn filling pump on.

vi) Observe the return and watch as the volume of bubbles decreases.

vii) When the system is full and bubbles have diminished, then close the return side valve while pump is still on.

Watch your pressure gauge until you reach your target pressure.

viii) Close the supply from filling station and shut off the filling station as soon as possible.

ix) Make sure to open the butterfly valve.

x) Activate your solar pump to be sure the pump is running. See the controller manual to learn how to

manipulate the controller settings in order to activate solar pump.

xi) Use the butterfly valve to adjust the circulation to the target flow rate.

xii) In case of exceeding pressure above target, release pressure via solar filling station until target psi is reached.

4) Programming the Controller (Refer to the controller’s manual for programming and maintenance)

a) Setting Differential

i) Typically, most controllers are pre-programmed with a Temp. Differential On of 12°F and Temp. Differential

Off of 5°F. Based on your region’s insolation levels, you may want to adjust these parameters in order to

increase your system’s efficiency. Most often the Differential on is set between 10-20°F.

b) Setting Tank High Limits

i) Make sure to check the tank temperature high limit. HelioMaxx systems are designed for the solar tank high

limit to be between 170-180°.

ii) Check the existing DHW tanks high limits to be sure the solar system does not exceed their parameters.

iii) If you decide to raise the tank limit above 145°F, it is mandatory to include an anti-scald mixing valve before

the water reaches the buildings hot water fixtures.

5) Operations and Maintenance (should be inspected at least once per year)

a) Measuring Glycol concentration

i) Each year it is important to make sure the concentration is consistent with manufacturers recommendation to

ensure the warranty is upheld

ii) Use a spectrometer or hydrometer to gain accurate results.

b) Glycol Acidity

i) Use a pH kit or digital pH tester and measure the pH of the glycol loop.

ii) Be sure the reading falls between 7.0-8.8

iii) Replace as needed following the steps in step 8

c) System Pressure

i) Ensure that the system is still operating at the target pressure set at step 7

d) Piping Insulation

i) Inspect insulation for gaps, UV exposure and possible destruction from vermin. Replace when needed

e) Emergency Valve-off Instructions


41

i) See piping diagrams in 6.1. Identify all isolation valves. Reverse the “normally open” (N.O.) valve to closed, and

the “normally closed” (N.C.) to open.

f) Leaving System unused

i) Open the fill and drain ports on the UniMaxx pump station to drain the collector and follow the “Emergency

Valve-off Instruction” above.

6) Maintaining Collectors

a) Yearly Inspection

i) collectors should be cleaned of dust, debris etc using soft cloth or soft bristle broom with hose and soapy

water

ii) Inspect all hardware to make sure nothing has loosened over time

b) Flat Plate Collectors

i) Inspect the glass for any possible cracks

c) Vacuum Heat Pipes - Inspection of broken tubes

i) Observe the chrome coating on the bottom of tubes, if turned to a powdery white, replace tube with new

replacement EVT. When removing the heat pipe be careful not to destroy as this can be re-used. If heat pipe is

destroyed you will need replacement tube WITH heat pipe.

Check all the gaps in insulation to be sure any tape or fasteners are still intact, replace or repair as needed.
