Introduction

Thank you for ordering the innowave Max™. The innowave Max™ brings a unique, fresh approach, and new look, to point-of-use systems in the marketplace. The system’s metallic cabinet complements every environment. Unlike a bottle water cooler, incoming tap water is treated as it’s needed, so the water is always fresh and great tasting. Best of all, there are no bottles to change and the supply is unlimited.

The innowave Max™ is designed to exceed the highest demands for cold and hot water in high traffic areas. It provides over 13 gallons of drinking water storage and it automatically refills for a continuous supply. The system boasts over five gallons of cold water storage – one of the highest cold water capacities for a point-of-use system on the market today!

The innowave Max™ uses a four-stage reverse osmosis process to treat your drinking water. First, a Sediment Filter collects sediment and solid particle matter. Then, a Carbon Filter reduces chlorine to protect the Reverse Osmosis Membrane. Next, the Reverse Osmosis Membrane rejects contaminants. Last, a Carbon Filter assures great-tasting, quality water. The result is greatly enhanced drinking water with reduced impurities and improved taste.

Note: In this manual, all references to innowave Max™ is denoted by the word “Max”.

Note: The Max is not intended for use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

Note: Check with your public works department for applicable local plumbing and sanitation codes. Follow local codes if they differ from the standards used in this manual.

To ensure proper and efficient functioning of the Max to your full satisfaction, carefully follow the instructions in this manual.

Safety Information

Electrical Safety

Only connect the power cord to a 120V properly grounded outlet.

Never pull the power plug from the outlet with a wet hand or allow the plug to get wet.

Keep the power cord out of heavy traffic areas. To avoid a fire hazard, never put the power cord under rugs, near radiators, stoves, or heaters.

Do not use a damaged power cord or plug. If the power cord is damaged, it must be replaced by a qualified service technician.

Do not use an extension cord with the Max.

Installation and Usage Safety

Keep the Max away from direct sunlight and excessive humidity.

Keep at least 4 inches from the wall.

Don’t lay the Max down on its side, if for some reason the unit was placed on its side, it must stand upright for a minimum of 2 hours before operation to allow the compressor to stabilize.

Connect the water supply to a cold water line only. Feedwater over 105 degrees F can damage the filters.

Never install the system where it could freeze.

If the feedwater pressure is over the maximum operating pressure of 100 psi, install a pressure-reducing valve in the water line.

Filters should be replaced on schedule. Overused filters will deteriorate the performance of the system.

Drain the water out of the storage tanks after long periods of non-usage, this will allow a fresh batch of water to fill the system.

Features

Electronic Control System

A smart electronic control system constantly monitors the functions of the Max including temperatures, water level, and checks for component faults.

Convenient Display

The display on the front of the machine provides important information including, water level, temperature, and UV cycle operation.

Extension of Cold Water With the “COLD II” function activated, water from the cold tank is periodically pumped up to a secondary insulated cold reservoir, increasing the amount of cold water available.

UV Recirculation System For one hour every three hours, a pump inside the machine sends water through a UV module exposing the water to a UV light which inactivates bacteria. This feature will keep the treated water in the storage tank fresh and prevent bacteria growth from getting out of control.

Booster Pump The booster pump will automatically increase the feedwater pressure to the reverse-osmosis membrane. This is very important if the feedwater pressure is very low since the reverse-osmosis system requires adequate pressure for optimal water production capacity.

Hot Water Safety Device The hot water faucet has a child safety device integrated into it. To dispense hot water, the red hot water button on the front of the faucet must be pressed in while pushing the cup-touch lever.

Water Supply Sensor The system can automatically sense if it has an adequate water supply to operate correctly.

Overfill Sensor The storage tank is protected by an overfill sensor that will stop the reverse-osmosis system from overfilling the storage tank.

Filtration System

The innowave Max utilizes a 5-stage water treatment process consisting of the following stages:

Stage 1: Sediment Filter This filter effectively reduces various foreign bodies that may come from the supply water and also protects the RO membrane. It also reduces dirt, sand, particles, and other sediments.

Stage 2: Pre Carbon Filter This activated carbon filter reduces chlorine, fluoride, odor, and other various organic contaminants and protects the RO membrane.

Stage 3: Reverse Osmosis Membrane Filter This thin-film composite (TFC) membrane reduces many organic, inorganic, and microbiological contaminants.

Stage 4: Post Carbon Filter This coconut-shell activated carbon filter polishes the taste and odor of the water coming from the reverse osmosis membrane.

Stage 5: Recirculating Ultra Violet Light The treated drinking water in the storage tank is occasionally pumped through a UV module which inactivates bacteria and keeps the storage tank from becoming contaminated.

Recommended Frequency for Filter Replacement

Sediment Filter 12 months Pre Carbon Filter 12 months RO Membrane 12 months Post Carbon Filter 12 months UV Lamp 12 months

Note: the above times are estimates only and may vary depending on feedwater conditions.

Principles of Operation

Note: The number designations in this sections pertain to the components shown on the flow diagram in the next section.

The feedwater is introduced to the innowave MAX through a ¼” O.D. orange plastic tubing (1) that extends out of the back of the machine. First the feedwater passes through a 5-micron sediment filter (2) that reduces the amount of large particles, like silt and sand, and helps to protect the other components in the system from sediment and debris.

Next the water flows through a low-pressure switch (L.P.S.) (3) that senses the pressure in the feedwater supply line. If the pressure is > 5 p.s.i. the L.P.S. will allow the reverse-osmosis (RO) system to operate. If the pressure is below 5 p.s.i. the RO system will shut down and the two bottom orange level bars on the front control display (26) will flash, indicating a feewater supply problem. The RO system will resume operation when feedwater pressure is re-introduced to the system.

After leaving the L.P.S. (3) water then flows through a normally closed solenoid valve called the feed valve (4), which is the main water control valve on the system. This valve (4) is controlled by the high-level float switch (16) in the storage tank (12). When the storage tank is full and the high-level float is lifted, the feed valve (4) will close and stop water production from the RO system. The feed valve (4) will only open again when the mid-level switch (15) in the storage tank (12) falls. This dead-band between the high-level (16) and mid-level (15) switches will prevent excessive starting and stopping of the RO system by only allowing a restart after drawing out a couple of gallons of water from a full state. The low-level switch (14) in the storage tank (12) will protect the hot tank (21) heating element by only allowing it to energize when there is enough water in the storage tank (12) to flood the hot water tank (21) below it. When the low-level switch is lifted, the two bottom level bars on the front control display (26) will illuminate which will indicate that the cold water tank (19), the hot water tank (21) and the extended cold tank (18) are full of water.

Next the water passes through a normally-open solenoid valve (N.O.S.) (5) that stays open until the overfill sensor (17) in the storage tank lid senses water, when the overfill probes senses water the N.O.S. (5) closes and the two top orange level bars on the front control display (26) will flash, indicating a problem with the primary level control float switch system.

From the N.O.S. valve (5) the feedwater moves on to the booster pump (6) which increases the pressure of the incoming feedwater supply. The booster pump (6) will try to increase the pressure to about 75 p.s.i., however, the actual boosted pressure will vary depending upon the actual feedwater pressure available.

Owner’s Manual

15 Rev. C 09/10

Increasing the feedwater pressure will maximize the RO production rate (>100 gpd) and allow the drain line to run further distances.

After the booster pump (6) water passes through a pre-carbon filter (7) that reduces chlorine and other organic contaminants that can harm the reverse-osmosis membrane (8) via hydrolysis.

The next stage in the treatment process is the reverse-osmosis (RO) membrane (8) which is constructed from a thin-film composite (TFC) material and has a low pressure rating of 50 gallons per day (gpd). More than 100 gpd can be achieved from the membrane (8) because of the booster pump’s assistance, which keeps a constant, high-pressure on the feedwater side of the membrane (8) that optimizes performance.

The pores of a RO membrane (8) are so small that they are very susceptible to clogging or fouling. To prevent fouling, RO membranes are designed to operate using cross-flow filtration in which the feedwater is constantly running across the membrane and flushing larger particles down the drain, only the very small molecules, including H2O are allowed to pass through the membrane. The drain line for the RO membrane is a ¼” O.D. blue plastic tube (24) that extends out of the back of the machine. Since the MAX has a booster pump the drain can be run greater distances than a system without a pump. In order to maintain proper pressure on the RO membrane the drain line must be restricted, which is achieved by the wastewater controller (9).

After the RO membrane (8) the treated water passes though a granular activated carbon post filter (10) that reduces remaining contaminants left after being treated by the RO membrane (8) and polishes the taste. A check valve fitting (11) is installed on the exit port of the post filter to prevent the treated water in the storage tank to flow back through the system. It also allows for easier filter changes because water from the storage tank (12) is not allowed to spill back though the check fitting (11).

After leaving the reverse-osmosis treatment system the treated water flows into the main storage tank (12). From the main storage tank (12) water will flow down into and flood the cold tank, the extended cold tanks and then begins to fill the hot tank. The hot tank heating element won’t turn on until all of the tanks excluding the main storage tank (12) are full of water and the low-level float switch (14) in the storage tank (12) is lifted. The RO system will continue to make water until the high-level float switch (16) is lifted which closes the normally closed feed valve (4) stopping the flow of feedwater to the system. Once the storage tank is full and the RO system is off it will only restart when approximately 2 gallons of water has been dispensed which is when the mid-level switch (15) will fall.

To turn on the cold and hot tanks (19 & 21) press the appropriate “cold” (28) or “hot” (27) button located behind the access panel (25) on the font of the machine. To turn on the Cold II feature press the “Cold II” button (30). The Cold II feature will allow cold water from the cold tank (19) to be occasionally pumped up into the extended cold tank (18) eventually making over 5 gallons of cold water available for dispensing. However, when the Cold II feature is activated the temperature of the dispensed cold water can fluctuate while the circulation pump (20) is moving water from the cold tank (19) to the extended cold tank (18), this rise in temperature is temporary and the machine will quickly attempt to chill the water back to its set temperature. This temporary temperature rise is caused by the warmer water in the extended cold tank (18) being exchanged with the water in the cold tank (19). To activate the hot water child safety feature press the “150 F” button (29). Activating this feature will only allow the water in the hot tank (21) to reach a maximum of 150 degrees Fahrenheit, which is hot, but not scalding hot water.

To turn off any of the “feature” buttons behind the front access panel (25) the user must hold the appropriate button for about 2 seconds.

Water temperatures in the cold and hot tank (19 & 21) of the MAX are regulated by the printed circuit board (PCB) sensing input from thermistors and the set temperatures are not adjustable. The real-time temperatures in the cold and hot tanks (19 & 21) are displayed graphically on the front control display by illuminated green and red indicator bars. Full bars illuminated will mean the machine has reached its minimum cold and maximum hot temperature. If there is a problem with the thermistors (open or closed circuit), the cold or hot temperature bars on the front control display (26) will flash.

The innowave MAX is equipped with a recirculating ultra-violet (UV) light module (13) with a built in pump. When the storage tank (12) has enough water the UV module (13) will circulate water in the storage tank (12) past the UV light for 1 hour every 3 hours. The operation of the UV module is indicated on the front control display (26) by the word “cycle” and three arrows rotating in sequence. If there is a problem with the UV module the UV indicator lights on the front control display will flash.

To dispense cold water from the innowave MAX the user must push the cup touch lever on the cold water faucet (23). For continuous cold water flow the cup touch lever can be pulled forward. To dispense hot water from the MAX the user must first push and hold the hot safety button on the faucet (22) and then press the cup touch lever. Continuous flow can also be enabled on the hot water faucet by pulling the cup touch lever forward; however the safety button must be pushed and held in while swinging the lever forward.
