Introduction
Better Water LLC 698 Swan Drive Smyrna, TN 37167 Phone 615-355-6063 Fax 615-355-6065
www.betterwater.com
The Reverse Osmosis (R.O.) Machine is a multiple-
membrane, device that is pressurized by a stainless steel
pump and motor. The Reverse Osmosis process uses a
semi-permeable membrane to separate and remove
dissolved solids, organics, Pyrogen, submicron colloidal
matter from the water. The process is called "reverse"
osmosis since it requires pressure to force pure water
across a membrane, leaving the impurities behind. Reverse
Osmosis is capable of removing 95%-99% of the total
dissolved solids (TDS) thus providing safe, pure water.
Based upon your facility’s specifications and information
about tap water data, the R.O. was designed and built to
exacting standards and Good Manufacturing Practices as
outlined by the FDA. The R.O. is a device that uses a
membrane separation process for removing solvent
(contaminants) from solution (tap water).
The R.O. is the most important and costly component in
the water treatment system. With appropriate pretreatment
of the tap water, proper cleaning and disinfection, the R.O.
membrane life can be prolonged for several years.

OSMOSIS EQUILIBRIUM REVERSE OSMOSIS
Osmonic
Pressure
Water flows from the lower
concentration of salts
across a permeable
membrane to the higher
concentration.
Osmotic Pressure is
the pressure required
to stop water flow and
reach equilibrium.
By applying pressure greater
than the osmotic pressure, the
flow of water is reversed. The
water flows from a higher
concentration of salts to a lower
concentration.

Feed Water
Requirements
The importance of monitoring and controlling the
municipal tap water can not be underestimated. The R.O.
feed water must meet the following parameters:
40 psi (Optimum) to 90 psi (Maximum). The minimum
pressure must be maintained with water flowing at the
maximum required flow-rate.
The Requirement for Feed Water will be determined by the
size and model of the specific R.O.
Refer to the unit’s Specification Sheet for specific flow
values. Chlorine is commonly used as a disinfecting agent
in municipal systems. Disinfection byproducts can form
when disinfectants, such as chlorine, react with naturally
present compounds in the water. Chlorine/Chloramines in
the RO unit feed water must be less than 0.1 ppm.
Silt Density Index (SDI) is a test to measure of the level of
suspended solids in feed water. High SDI values can lead
to membrane fouling. A SDI of less than 3 is considered
acceptable for the R.O. system.
Turbidity is the amount of small particles of solid matter
suspended in water as measured by the amount of
scattering and absorption of light rays caused by the
particles. Feed water turbidity must be less than 1
nephelometric turbidity units (NTU).

Hardness is a characteristic of feed water due to the
presence of dissolved calcium and magnesium; water
hardness is responsible for most scale formation and can
form insoluble residue in pipes and other water contact
surfaces. Hardness is usually expressed in grains per gallon
or parts per million, all as calcium carbonate equivalent.
Hardness level of feed water for the R.O. system must be
less than 2 gpg (grains per-gallon) or 34.2 ppm (parts-per-
million).
Feed water temperature must be between 70 and 92ºF
(Optimum: 77ºF). The R.O. will shut-down in a high feed
temperature alarm at 93ºF or as set by the installer.
If high temperature alarm conditions are causing frequent
shut downs, contact Better Water for assistance.

Digital Flush Timer
The Digital Flush Timer is an important component of the
Reverse Osmosis Machine. The flush timer is a 24-hour
adjustable 24 volt Digital mechanism that controls the
frequency and duration of the Flush Cycle.
The Flush timer serves two purposes: It is used to set the
time of day, and the frequency and duration of the Flush
Cycle(s).
The digital flush timer is equipped with a battery back-up,
so loss of power to the R.O. will not affect the timer
operation. However, the actual life of the battery is not
known so the timer should be checked monthly for correct
time of day setting.
The Flush Timer was preset set by the system installers on
the day of the installation. Once the Frequency and the
Length of the Flush Cycle have been set, that setting will
remain until manually changed.
For details regarding the Flush Timer, see the section
Maintenance – Flush Timer Adjustment.

Miscellaneous Features
The Low Pressure Switch is located on the suction side
of the pump. The switch, via the main controller board,
acts to shut down the R.O. in the event of insufficient
pressure to the RO.
A keyed switch is an additional safety feature and
prevents unauthorized activation of the disinfect cycle. A
key must be inserted to place the unit into the disinfect
mode.
A red alarm light will turn on when any alarm conditions
occur. The light will remain on until the alarms conditions
are cleared and the alarms are reset by the RESET button
on the Control Panel.

The .03 final Pyrogen filter is located on the left
side of the R.O. on the Product Line. There is a
Sanitary Sampling Port after the filter.
On 2436 and 3046 R.O. units this filter uses a
standard 20” Filter Housing and on 2020 R.O.
units the filter is a cartridge.
The .03 filter should be changed every 6 months.
The Product Pressure Gauge on the front of the
R.O. will show the pressure before this filter.
On a Tank Feed System, the product hose from
the R.O. is connected to the reservoir via a 3 way
valve. There is no pressure gauge on the outlet
side of the filter.
On a Direct Feed System, an additional outlet
pressure gauge is installed on this filter. The
Product Pressure Gauge on the front of the R.O.
will display the pressure on the inlet side of the
filter. Both of these gauges should be monitored
and the filter should be changed if the ∆P reaches
or exceeds 20psi.

Controller
Variable Frequency Drive
Variable-frequency drives are reliable, easy to operate,
increase the degree of flow control, and reduce pump
noise. A variable-frequency drive is an electronic
controller that adjusts the speed of an electric (R.O. Pump)
motor by modulating the power being delivered. Variable
frequency drives provide continuous control matching
motor speed to the specific demands of the work being
performed.
The performance is monitored daily by the user to ensure
design pressure is being maintained.
The probability of failure is remote; however should the
variable frequency drive fail, the R.O. pump will not
operate properly.
Other than routine cleaning of the exterior surfaces, there
is no required cleaning or maintenance schedule or
procedure.

The R.O. Remote Alarm Box is a molded plastic box,
usually located on the patient floor, in a position where it
can be easily seen by clinic personnel during normal work
duties. The box is equipped with audible and visual alarms
that monitor the R.O. and Reservoir water level. The
Remote Alarm Monitoring Box requires no external power
supply, but receives 24vac power and signals from the
R.O. which it is monitoring. This box has 2 RED lights
that will illuminate when the R.O. goes into an alarm
condition or when the water level in the reservoir falls
below the bottom float, and 1 AMBER light that will
illuminate and flash when the R.O. is in Disinfect Mode.
AAMI standards require that the R.O. alarms be audible in
the patient area. If the R.O. is located close enough to be
heard in the patient area, the remote alarm may be omitted
This device is automatic and requires no daily startup
procedures.

System Operation
Before you start using this device, Operators must
read and understand this manual in its entirety. This
manual of Operator's Instructions describes in
considerable detail all of the steps and procedures
required to safely operate this device. With proper
operation, maintenance and care, this device should
give you years of reliable service.
It is unsafe to operate this device without a basic
understanding of water treatment and a thorough
understanding of the contents of this manual.
The R.O. was designed and built to your facility’s
specifications and information regarding the current
tap water conditions at your site. There is not a
Reverse Osmosis Machine on the market that is a
panacea for all water treatment requirements. The
R.O. cannot do the job alone. It is imperative to
monitor the tap water and feed water conditions.
Incoming tap water contaminants, temperature,
pH, pressure and flow-rates have a direct impact
on the quality and quantity of the Reverse
Osmosis Machine output.

The Operator must be aware of changing tap water
conditions. This can be easily accomplished with
good, two-way communications with the local
municipal water supplier and with routine testing of
the tap water.
To emphasize the importance of water treatment and
proper use of water treatment equipment used for
hemodialysis, the following is quoted from Health
and Human Services Publication FDA 89-4234,
"Numerous reports have documented that use of inadequately
treated water for hemodialysis poses a severe threat to the
health and safety of the hemodialysis patient. Despite this,
water treatment and water quality are often neglected areas of
hemodialysis. A major reason for this neglect is that water
treatment is a Technically complex subject which is not
generally a part of the education and training of clinical staff
in hemodialysis facilities."

Unit Adjustments On occasion, the R.O. may require adjustments that can be
performed by qualified operators. There are many factors
that can affect the performance of the R.O. If minor
adjustments to the R.O. do not produce the desired results,
you must investigate changes in the water feeding the R.O.
Water pH, temperature, pressure, TDS, and flow changes
may cause a drastic reduction in the R.O. performance. In
worst case situations, changes to the water can create
conditions the R.O. cannot handle without supplemental
processing.
PREPARATION: Before making any adjustments,
read this entire section and pay close attention to
cautions, notes, and items marked important.

measuring any possible system changes in the future.
On Direct Feed Systems, the product pressure should be
adjusted only when there are no requirements for R.O.
water. Locate the pressure T-handle on the pressure
regulating valve at the end of the distribution loop (return to

Flush Timer

www.betterwater.com
Normally, the Reverse Osmosis Machine Membranes will
be flushed multiple times per day and for only 15 minutes
per flush. If your operation is considered less than normal
(less than 6 days a week operation), the FREQUENCY of
the FLUSH CYCLE should be set to occur more often. In
this case, we recommend that the FREQUENCY of the
FLUSH CYCLE should be set to occur (at a minimum) once
every four hours for 15 minutes per flush cycle.
If you should elect to operate the clinic (water treatment
system) on an unscheduled basis, there would be no
problem, because the OPERATE-FLUSH switch controls
the Flush Timer. In other words, the Flush Timer would be
inactivated when the OPERATE-FLUSH switch is in the
OPERATE position, and when the OPERATE-FLUSH
switch is returned to the FLUSH position, the FLUSH
TIMER would be reactivated. In either position of the
OPERATE-FLUSH switch, the FLUSH TIMER CLOCK
would continue to keep the correct time of the day; however,
the position of the OPERATE-FLUSH switch would
determine if a flush of the membranes would occur or not.
CAUTION
The time that a FLUSH CYCLE would occur should not coincide with the
backwash or regeneration of a pre-treatment component.

When trouble shooting VFD issues Call Better Water
for technical assistance.
Located on the VFD front panel are 2 arrow keys; an up
arrow key and a down arrow key. Also located on the
Front panel display is a RUN and a STOP button (which
are inactive during operation), a MODE and a ENT
(ENTER) button. The VFD set point and Product/Reject
flow is set by adjusting the up or down arrow key. To
properly set the correct set point and Product/Reject of the
R.O., the R.O. must be on and running.
Run the R.O. 5 minutes before setting the set point. The
set point relates to the desired product and reject flow of
the R.O. Example: A 4 membrane array R.O. will be set at
5 GPM Product and 5 GPM Reject at 50% recovery. To
calculate the flow, count how many membranes that are in
the array then multiply by 1.25 GPM. 4 membranes X
1.25= 5.0 GPM Rated Product Flow plus or minus 20%. At
50% recovery the Reject flow will be 5 GPM also. When
setting the correct flow, the Post Filter pressure should be
at 40 psi on the R.O. when setting. If not, adjust the Post
City Boost Pressure on the Pre-Treatment. Push the up or
down arrow key to set the desired Product flow and set
point. Once set, then push the ENT (ENTER) button.

The transducer is threaded into a tee located post R.O.
Pump/pre membrane. The transducer communicates with the
VFD to maintain the set point by analyzing pressure
differentials pre and post R.O. Pump. Example: If the pre or
post R.O. Pump pressure drops the transducer transmits that
signal to the VFD. The VFD will increase the frequency to
compensate for the pressure loss and will try to maintain set
point and Product/Reject flows. The same is true if the pre

VFD error to occur. Check the Breaker in the R.O. Junction
first. If it is tripped reset it. If not proceed to the VFD
control box and open the box.
If the VFD is flashing a code: OC1, OC2, OC3, EPHI,
EPHO, OP1, OP2, OP3, OL1 or OL2. This usually means
the VFD tripped.
If OC1, OC2 or OC3, this means there has been a over
current event that has occurred.
EPHI or EPHO means there has either been a phase input or
phase output event.
OP1, OP2 or OP3 means there has been a over voltage
event.
OL1 or OL2 means there has been a overload event.
If LStP is flashing in the display that means the VFD is idle
and below minimum programmed set point (This set point is
6 Hz and is pre-programmed and is locked out to the end
user.) If any of these error codes are displayed with the
exception of LStP, turn Operate switch to OFF then unplug
or disconnect main power. Wait for 10 to 15 seconds and for
the VFD display to power down. Then reconnect or plug
back in main power then turn Operate switch back to

3. When Disinfect tank has been filled with Product
water connect the supplied ¾” Reject hose from the
Disinfect tank to the R.O. Drain. Next connect the
supplied ¾” Feed hose from the Disinfect tank to the
Clean/Disinfect ball valve located at the base of the
pump. Before completely tightening the Parker fitting
to Clean/Disinfect ball valve open the Disinfect tank
ball valve to prime the feed hose. When water starts
trickling out of the Parker fitting then tighten the
Parker Fitting. Note: If the Disinfect tank feed hose
hasn’t been properly primed the pump will air lock
and could cause damage to the pump.
4. Before adding the Cleaners or Disinfectant start the
R.O. in Disinfect. Set the Operate-Flush Switch to
Operate, Operate-Disinfect-Off Switch to Disinfect,
then turn Operate-Disinfect Key Switch to Disinfect.
The R.O. will start up immediately. Verify flow by
looking at the Product and Reject Flow Meters and
visually see if water flowing back in to the Disinfect
tank through the Product and Drain hoses.
5. Before beginning cleaning with Low or High pH
cleaners it is recommended that a baseline pH
reading be taken form the Product returning into
the Disinfect tank.
6. Cleaners. If Cleaning add 1lb or 454 grams of either
Low pH or High pH cleaner to the Disinfect tank.
During circulation while cleaning the operator should
verify the pH of the cleaner used by checking the
Product returning back to Disinfect tank. For Low pH
cleaner the pH should read less than 3 ph units. For
High pH cleaner the ph should read greater than 9 pH
units.

a negative reading is obtained. When a negative
reading has been obtained then turn off the R.O. for a
Rebound Break.
13. The Rebound Break is for 15 to 20 minutes. This is
highly recommended as residual disinfectant could
still be present in the membranes even if a negative
result was obtained during rinsing. After the Rebound
break time has been completed restart the R.O. in
normal Operate again and recheck Residual again. If
the Residual is positive or negative continue rinsing
an additional 15 minutes before hooking Product line
back to the Storage Tank. Turn 3-way valve on the
storage tank back to tank fill.
14. Direct Feed cleaning and disinfection. Leave the
Three-Way loop return valve on to RO. Follow the
above steps. When cleaning or disinfection is
completed turn the Three-Way loop return valve to
rinse cleaners and disinfectants to drain from the RO
and Loop. When rinsing is completed and RO is clear
turn the Three-Way loop return valve back on to RO.

Sanitizing the Sanitary Sample Ports
Sanitize the Sanitary Sampling Port immediately before
each sampling operation.
1. Turn the port stem to the left, and allow a full flow of
liquid to pass out of the port for 1-2 minutes. Then
close the port by turning the stem to the right.
2. Fill a 20ml plastic polypropylene syringe with at least
10ml of 70% ethanol, 90% isopropyl alcohol, or 3%
hydrogen peroxide solution. Attach the port needle to
the syringe.
3. Insert the needle all the way into the port through the
stem opening, and express the sanitant into the port.
Allow a few milliliters to flow out of the port outlet.
4. As the needle is removed from the opening, squirt a
few milliliters of the sanitant over the outer surface of
the stem.
5. When ready to sample, open the port and rinse
product water 1 to 2 minutes before sampling. This
rinses the residuals and any endotoxins from the
sample port.

On occasion, your R.O. Membranes will require cleaning
and disinfecting with chemical cleaners and disinfectants to
regain maximum performance.
Membrane fouling is indicated when:
• The Product Flow decreases and the Reject Flow
increases, and the two cannot be adjusted to design
specifications.
• The Pump Pressure increases, the Membrane Pressure
increases, and the Reject Pressure decreases.
• The Quality Monitor indicates a continuous decline in
water quality.
• Monthly disinfection is recommended.
This procedure covers the mechanical steps required to clean
and disinfect the Reverse Osmosis Machine Membranes.
The preparation of the chemical cleaning solution must be in
accordance with the specifications established for the
selected cleaning chemical.
The cleaning chemical must be handled in accordance with
its Material Safety Data Sheet (MSDS).
NOTICE:
Other factors, such as changes in the tap water pH, TDS, temperature,
and/or pressure can cause drastic changes in the overall performance of
the RO.

Last Reviewed Date 10/18/2012
Page 1 of 1
OVERVIEW:
The manufacturer discontinued the model of the VFD used in Better Water LLC’s 2436 ROs and Pretreatment devices in October of 2012. The replacement model is functionally the same with the exception of the use of one of the terminal posts, which will require the relocation of a wire if the older model VFD is replaced with a newer model. Better Water LLC’s part number of EQMOBO01353 which is the “3 Phase-In / 3 Phase-Out / 3 Horsepower
VFD“ will remain the same. The difference between these two models is mostly cosmetic. See the pictures below of the old and new models.
WIRE RELOCATION:
If the older model VFD has to be replaced, do the following, using the before and after pictures as reference: 1. Take note of the location of the white wire (from the pressure transducer) on the older model VFD’s terminal
post labeled VIA.
2. Replace the older model VFD with the newer model VFD. 3. On the newer model VFD, relocate the white wire (from the pressure transducer) to the terminal post labeled
VIC.

Replacing Chromalox Temperature Controller with Omron Temperature Controller
TSB 2014002
Created/Last Revised Date 12/05/14
Last Reviewed Date 12/05/14
Page 1 of 3
OVERVIEW: Effective December 5, 2014, Better Water will start using the Omron Temperature Controller instead of the Chromalox Temperature Controller because of easier use and programmability. Prior to this, there have been two Chromalox models used. When replacing a Chromalox with an Omron, the only difference is the position of the connecting wires. The part number ELCPD100001 remains the same. The differences between these models and the wiring connection changes are detailed below. Refer to the pictures below to determine which model you have: If replacing and older model Chromalox model 1600 Temperature Controller you will also need to order the new model’s bracket whose part number is FXBROO00894, which is slightly larger. PROCEDURE: 1. Turn OFF power to the RO. 2. Open the cover to the Control Box. 3. Unclip the old model Chromalox Temperature Controller, and gently pull it forward so the attached wires can be accessed.
TECHNICAL SERVICE BULLETIN
WARNING To avoid electrical shock, turn the power to the RO OFF, and unplug it from the electrical outlet.
A lock-out tag should be placed on the unit to prevent accidental use while this Replacement is underway.
