Congratulations! You are now a proud owner of the finest reverse osmosis filtration system available.
Marine Depot has assembled a high quality water purifying system that turns ordinary tap water into
sparkling, great-tasting, healthy drinking and aquarium water by combining filtration and absorption.
With this unit you can be assured that your aquatic animals and your family are enjoying the highest
quality water possible.
SYSTEM REQUIREMENTS
Operating Pressure: 45-85 PSI
Optimal Input Water Temperature: 70-77° F (21-25° C)
Output Rating: Output of Marine Depot KleanWater RO and RO/DI systems are measured with a
water pressure of 50 PSI, 75° F water and an input TDS of 125ppm. Lower water pressure, lower
temperature and/or high TDS will result in lower output.
SYSTEM DESCRIPTION
The Marine Depot KleanWater Reverse Osmosis and Reverse Osmosis / Deionization Systems are
available in many different configurations ranging from a simple 4-Stage RO-Only system to a feature-
rich 6-Stage RO/DI System.
Sediment Pre-lter
First, the incoming feed water is passed through a one micron sediment pre-filter. This filter removes
silt and other particulate matters that may clog the TFC membrane.
Carbon Pre-lter
The second stage of filtration is a carbon pre-filter (select models feature two carbon cartridges). This
filtration step removes organics, chlorine, chloramine and other chemicals from the feed water that
can damage the membrane. For the most effective chloramine removal, we recommend replacing the
filters with our Chloramine-X GAC Carbon Filters once your current filters are exhausted.
RO TFC Membrane
The third filtration stage is a high rejection thin film composite (TFC) membrane. It removes 95%-98%
of inorganic salts, heavy metals, bacteria and almost all high molecular weight organics in the water.
The correct waste water to product water ratio is 3 to 4 parts of waste water for each 1 part of product
water.
Deionization Cartridge (on select models)
The fourth stage moves water through a Deionization Cartridge (select models feature two DI
cartridges). As water passes through a bed of ion exchange resins, these resins attract and absorb
ionic contaminants: cation resins absorb positively charged ions, and anion resins absorb negatively
charged ions. Deionization cartridges are designed to reduce silica, nitrates and phosphate levels in the
low ppb range and are capable of producing 18 meg-ohm-cm resistivity water. This is exactly why
RO/DI systems are the best tap water filtration method to provide ultra pure water for your aquarium.

SYSTEM DIAGRAM
Check the box thoroughly for all parts listed for the type of unit purchased. All units come standard
with a Garden Hose Fitting. If the feed water (faucet or laundry sink) does not have ¾” garden hose
threads, you will need to purchase a Feed Water Adapter, or a Faucet Coupler. These and other sold
separately plumbing parts are available at MarineDepot.com or your local hardware store.
The pressure gauge (Figure A; included with Advanced models) will allow you to monitor the pressure
of the system and make sure that the filter is receiving sufficient water pressure to operate efficiently
as well as monitor your pre-filters. It will indicate, via a drop in pressure, when the sediment and
carbon block filters are clogged and need to be replaced.
The Dual or Triple TDS meter (Figure A; included with Advanced models) is used to monitor the
condition of the TFC membrane and DI cartridge.
Flush Valve kit (Figure A; included with Advanced models) purges the TFC membrane and helps to
extend membrane and DI cartridge life. We recommend flushing your membrane for 30 seconds
before and after each use.
STORAGE
When the unit is not in use, it is important to keep the TFC membrane hydrated. The TFC membrane
must not be allowed to dry out. Keep the unit in a cool location and keep all inlet and outlet lines above
the unit so the water will remain in the unit. If the RO (or RO/DI) system will not be used for more than
4 weeks, remove the TFC membrane and store it in a refrigerator inside a Ziploc bag filled with a small
amount of purified water. Do not allow the RO (or RO/DI) unit to be exposed to freezing conditions or
temperatures above 100°F.

INSTALLATION INSTRUCTIONS
NOTE: It is YOUR responsibility to ensure all fittings are tight and that codes are met.
WARNING: Household water pressure can cause leaks and damage the surrounding building or fixtures
if not properly installed. You must check all fittings for tightness. When installing canisters, hand-tighten
ONLY! Filter wrench is only used for removal. Marine Depot assumes no responsibility for water damage
due to leaks. DO NOT expose unit to direct sunlight or freezing conditions!
Marine Depot KleanWater Systems can be mounted to any secure location using hardware screws. Keep in
mind that the filter system will gain a substantial amount of weight when it is full of water. For this reason, it
is necessary that the filter system be mounted to a strong backing.
Mount the filter system level, with clearance for all housings and hoses vertically and horizontally. Also
keep in mind that there will be space needed below the unit to accomplish regular maintenance of the filter
system such as pre-filter removal. Additional hardware and/or plumbing parts are available at MarineDepot.
com or your local hardware or plumbing supply stores.
* For RO/DI systems, you will need to remove the DI cartridge
from the far left chamber(s) before turning on the cold
water supply.
Place the yellow waste water line and blue product water line
into your drain. Do not restrict flow from these lines. Do not
install the TFC membrane at this point. Slowly open the
cold water supply valve and allow the first two housings
to fill. You may use pressure up to 85 psi. Double check
the system to ensure that all fittings are tight and leak-
free before leaving the system unattended.

Attach the garden hose adapter to your cold-water source.
Never run hot water (greater than 100° F or 38° C) through
the system. Attach one end of the black feed water tubing
to the garden hose adapter and the other end to the IN
port of the sediment filter canister on the right side of your
Kleanwater System.

Allow the cold water to run for 5 minutes to
flush the sediment and carbon-block pre-filters
(already installed). Flushing the pre-filters will
help to maximize the TFC membrane life.
Next, turn off the water supply. Remove the TFC
membrane (blue tubular filter) from the protective bag
and install the membrane into the TFC housing on the top
of the RO System. You will need to disconnect the tubing
to be able to unscrew the cap. Take careful note of tubing
colors and connection location on TFC housing. Securely
and fully seat the TFC membrane into the housing: there
should be about ¾” of space from the lip of the housing
to the top of the TFC membrane. Once the TFC membrane
is seated, screw on the top and reconnect the tubing.
Reverse osmosis membranes are packed with an
anti-bacterial agent to keep them sterile prior to use.
This agent should be flushed away to avoid human
or animal consumption. Turn on the water once
again and allow the unit to run for 30 minutes to
flush out the anti-bacterial agent.
For RO systems, allow the system to flush completely for 30 minutes and discard the initial batch
of water produced. Once flushed, the water from the product water line (blue) can now be collected
for use.
For RO/DI systems, allow the system to flush completely for 30 minutes. Then re-install the DI
cartridge(s) into the far left canister(s). Once DI cartridge(s) are installed, discard the first 2 gallons
of product water and start collecting pure RO/DI water for use thereafter. *Trapped air in the DI
cartridge is a normal condition and will not affect the operation of the DI cartridge.

Gauge
The Kleanwater Advanced RO/DI Systems are available in 4 stage (shown above) and 6 stage options. The Pressure
Gauge and Flush Valve are pre-installed on your RO/DI system. The TDS Meter is packaged separately and will need
to be installed in order to measure the total dissolved solids (TDS) of water passing through your system.
The Pressure Gauge allows you to monitor water pressure going into your RO/DI system. A drop in water pressure
indicates the sediment and carbon pre-filters are clogged and need to be replaced.
The Flush Valve is used to flush your TFC membrane for 30 seconds before and after each use. Simply open the
valve so the knob is parallel to the tubing to flush your system. After thirty seconds, close the valve and begin
collecting RO/DI filtered water.
The TDS Meter includes two probes inserted into white tee fittings. These tee fittings w/ probe will need to be spliced
into the tubing network on your RO/DI system for use (shown below). We recommend installing the first probe in
between the TFC Membrane and DI cartridge in order to monitor the TFC membrane performance. The second probe
should be spliced into the product water line after the DI Cartridge to monitor DI performance.
1. Cut tubing at desired
location of TDS probe
2. Insert Tee fitting with
probe by connecting tubing
to each side.

MEMBRANE & FILTER CARTRIDGE REPLACEMENT*
Sediment Cartridge – Change when visibly dirty (4-8 months), or when system pressure drops by
more than 5 PSI
Carbon Cartridge – Change at the same time the sediment filter is changed (4-8 months)
DI Cartridge – The color of the DI resin will begin to turn orange from the bottom up. Replace the
cartridge once it has reached approximately 1” from the top of the cartridge(s). To more accurately
determine when to replace the DI cartridge, use your TDS monitor or meter. You will notice a dramatic
rise in the TDS level once the resin is exhausted.
Thin Film Composite (TFC) Membrane – Should be changed when rejection rate drops below 95%.
For example, if your tap water TDS is 100ppm, water exiting the TFC membrane should be 5ppm or
less. TFC membranes will typically last about 1-2 years. The use of a flush valve kit is recommended to
help extend the life of the TFC membrane.
*All listed service times are approximate. Actual service life may be significantly longer
or shorter depending on the water source quality and how often the unit is used.
Problem Possible Causes Solutions
Zero product water - missing flow restrictor - install flow restrictor
- dried-up or damaged TFC membrane - install new TFC membrane
Slow water production - clogged pre-filters - install new pre-filters
- low water pressure (< 45 PSI) - install booster pump or use higher
output TFC membrane
- low water temperature - install booster pump or use higher
output TFC membrane
- hard water or high TDS - install booster pump or use higher
output TFC membrane
- damaged TFC membrane - install new TFC membrane
Too much product water,
too little waste water, or DI
exhausts quickly
- product and waste water lines reversed - reverse product and waste water lines
on TFC membrane
- TFC membrane not fully seated - remove then re-insert TFC membrane
- damaged / ruptured TFC membrane - install new TFC membrane
- if chloramines are present, the carbon
filter may be exhausted
- replace carbon filter with
Chloramine-X filters and DI cartridge
TROUBLESHOOTING
Your new Marine Depot KleanWater RO or RO/DI filter should work trouble-free out of the box. If you
have difficulties or questions, please contact Marine Depot at 1-800-566-3474.
