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 pressurereducing 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.

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.

Rev. C 09/10
Owner’s Manual
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 reverseosmosis 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 midlevel 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.
