OVERVIEW:
Maxxima unit incorporates a TFC or
Hi-S
membrane so it can be run on municipal or
™
™
well water systems. Chlorine can damage a TFC membrane, so proper maintenance is
essential. The water in our taps is filled with all sorts of toxic materials. Among these can
be lead, mercury, arsenic, chromium, pesticides, herbicides, industrial pollutants (carbon
tetrachloride, vinyl chloride, benzine etc.), gasoline, and trihalomethanes (from reactions
between organic matter and chlorine), chlorine, radium, and radon gas to name just a few.
Some substances can be toxic to humans and to aquarium fish. Phosphates and silicates
are very common in tap water, though usually not toxic to humans, these cause
undesirable algae growths in all types of aquariums.
Utilizing Reverse Osmosis will remove the majority of these contaminates from the water.
The Maxxima unit adds a post deionization resin filter to polish the R/O water to 99%
™
removal. This highly filtered water is not recommended for drinking due to its lack of minerals
and possible odd taste. Listed below are typical removal percentages, actual percentages
will vary depending on exact chemistry, temperature, pressure and TDS of your water.

There are certain factors that lower product water production. The first is water pressure.
The ideal water pressure should be 65 psi. A water pressure of 45psi will reduce the rated
Gallons Per Day(GPD) by one half. The second condition is water temperature. The ideal
o
o
o
o
o
operational temperature should be 70 to 77 F, 21 to 25 C. Low water temperatures like 50
o
F, 10 C restrict the output to half. NEVER run hot or mixed hot/cold water to the unit. Only
run the cold water. The third and final condition is the TDS or Total Dissolved Solids of the tap
water. These units are rated for 200 ppm(parts per million) of TDS. High TDS can also lower
output.
INSTALLATION:
NOTE: THIS UNIT SHOULD BE INSTALLED BY A LICENSED PLUMBER
TO ADHERE TO ALL LOCAL CODES. IT IS THE RESPONSIBILITY OF
THE PURCHASER TO INSURE THAT ALL FITTINGS ARE TIGHT AND
THAT CODES ARE MET.
WARNING:
HOUSEHOLD WATER PRESSURE CAN CAUSE LEAKS
AND DAMAGE SURROUNDING BUILDING AND FIXTURES IF NOT
PROPERLY INSTALLED!
User must check all fittings for tightness!
KENT MARINE ASSUMES NO RESPONSIBILITY FOR WATER DAMAGE
DUE TO LEAKS!
Check the box thoroughly for all parts listed on the other side of these
instructions for the type of unit purchased. All units come standard with a Garden Hose
Fitting(GHF). If the feed water (faucet or sink) does not have ¾ “ garden hose threads, you
will need to purchase an adapter, a FAUS; chrome diverter fitting (fits standard faucet
threads), or use an alternative, under the counter device like a SV. After you have the feed
line(yellow tubing) installed , you need a drain to dispose of the waste water(orange Tubing).
If the unit is going to be portable, you can run the waste line down the sink. If you are installing
the unit permanently, you should purchase our DSAD(drain saddle). This saddle fits standard
sink drain piping. Insert the membrane as shown in diagram 1 & 2 on the opposite side of
these instructions. After membrane insertion, make sure the bottom canisters are tightened
with the supplied canister wrench. Check all compression fittings for proper tightness. Under
normal operation, the full Jaco fitting will not need to be removed from any of the unit's
components. If one is removed, the pipe threads will need to be re-Teflon taped (leaving the
first two threads exposed) prior to installing back into the component. The unit is now ready for
operation. See below for new unit information.
OPERATION AND MAINTENANCE:
When operating the unit for the first time, follow these steps: 1-Remove the cartridge from the
third canister. Store the removed cartridge in an air tight container or bag, this is to prevent the
resin from drying out. 2-Replace the canisters. 3-Turn the tap water source all the way on.
Check the unit thoroughly for leaks and proper membrane operation(test alkalinity, should be
zero). 4-Run the unit and discard the first 10 to 12 gallons of product water. This is to flush the
membrane of the protective fluid as stated on the membrane's heat sealed bag. The
membranes are shipped almost completely dry to preserve them in shipment. Since they are
dry, you might not get your rated GPD at first. After the 10 to 12 gallons have run through,
return the removed cartridge back to the original canister, now the water is ready for use. 10
days of continuous running is required for complete membrane hydration. During this time
the water is still properly filtered and can be used as normal, although output may be low. This
does not mean you have to run the unit for this time period, only that when 10 days of running
is reached by normal operation.
Reverse Osmosis membranes simulate the membranes within our bodies, so they are
delicate. The membranes, once hydrated, cannot be allowed to dry out. When a membrane
dries, it is no longer able to purify the water and would need to be replaced. When the unit is
not operating, the membrane housing MUST stay wet. If the unit is portable and makes water
once or so a month, store the unit with the tubing above the membrane housing to prevent
draining. If the unit is not going to produce water for over 4 weeks, the membrane needs to be
removed from the membrane housing and stored in a plastic, air tight bag with 2 tablespoons
of product water and placed in the refrigerator. Doing this will prolong the membrane life. Do
not let the membrane freeze. Regular maintenance of the R/O unit consists of keeping track of
about how much water the unit is producing. This can be estimated. The following chart is the
recommended change times for all the filters.

Membranes for all Units

MHiS35
,
MHiS60
:
Under average conditions this membrane can filter
25,000 gallons or around 3 to 5 years of service. The
existence of fouling chemicals in the tap water like Iron,
Calcium, or Magnesium, will reduce the membrane
life exponentially. Kent Marine makes an add-on called
the
FLUSHKIT
. Adding this kit will greatly decrease
the chances of the fouling chemicals from destroying
the membrane.
Kent Marine makes add on kits to enhance the performance of these units. Here are some
examples. The
FVKITKENT
is a complete kit for filling up a reservoir container or sump and
shutting off the R/O unit by the means of a plastic float valve. We also have a drinking water
system called the
COMKITPLUS
. This system includes a 2.5 gallon pressurized tank and bar
faucet for dispensing filtered water and the solenoid to shut off the unit(drinking water from a
Maxxima unit
must be taken before
resin filtration). For more information about all our kits,
™
either call your supplier or look up our web site at www.kentmarine.com.
TROUBLESHOOTING:
Too much product water, little waste or resin exhausts quickly: Cause: the membrane is
not fully seated in the housing. See diagram 1 & 2 from opposite side of these instructions.
Not enough product water, lots of waste: Cause: Check the TDS, Temperature, PSI as stated
in the Overview section. Make sure you have given the membrane enough time to completely
®
hydrate. If all the common problems have been ruled out, contact Kent Marine 's Technical
Department for further assistance.
