A. IMPORTANTWATERQUALITYASSURANCE
REQUIREMENTS
Reverse Osmosis drinking water appliances contain treat-
ment components that are critical for the effective reduction of
Total Dissolved Solids (TDS) as well as inorganic chemical con-
taminants. Water Factory Systems
™
strongly recommends that
the user test the water periodically (every six to twelve months
minimum) to verify that the appliance is performing satisfac-
torily. Your dealer may offer a water testing service. Routine
maintenance is necessary in the form of prefilter, postfilter, and
membrane replacement, based on the following guidelines:
•
Sediment,Carbon,orSediment/CarbonPrefilters,and
Carbon Postfilters: Change every 12 months or sooner
depending on the feed water quality.
•
RO Membrane: Change it as required based on Percent
Rejection. A testing service may be offered by your dealer
every 36 months or sooner.
B. REPLACINGTHEFILTERCARTRIDGES
The life of the prefilter cartridge generally depends on
the local water conditions (i.e., dirt, rust and/or chlorine
levels) while the life of the postfilter cartridge(s) is generally
determined by the length of service.
When to Replace the Sediment Replacement Filter
•
Every twelve (12) months
or sooner depending on local water
conditions.
•
Anoticeabledecreaseinwaterproductionisanindication
that the filter requires changing.
When to Replace the Granulated Carbon Replacement
Filter
The granulated carbon replacement filter reduces free chlorine
in the feed water supply to protect the TFCM membrane from
chlorine attack. To find out the chlorine level in a water supply,
call the public water supplier.
When to Replace the Carbon Block Replacement
Post-Filter
• If the filter is being used to control tastes and odors, replace it
every twelve (12) months or sooner depending on local water
conditions.
When to Replace the Carbon Postfilter Cartridge
Change at a minimum of 12 months or sooner, depending
on feed water quality.
How to Replace the Prefilter and
Postfilter Cartridges
1) Lift up on the faucet handle to drain the tank. Close the
cold water supply valve. Wait five (5) minutes for the
filtration assembly to completely depressurize.
2) Remove cover and twist the filter cartridge 1/4 turn
clockwise so that the
ears on the cartridge are able to disengage from the
head. Firmly pull the cartridge from the head. It may
be necessary to twist the cartridge slightly from side to
side to help free it. (See Fig. 8)
3) Remove the new filter cartridge from its sanitary sealed
wrapper. (Double check to see that it is the correct
replacement by comparing the labels.)
4) Using tap water, wet the o-ring seals to make cartridge
insertion easier.
5) Line up the cartridge ears, insert the cartridge and push
it into the head until it is fully seated. Twist the
cartridge 1/4 turn counterclockwise to lock it into place.
6) Open the cold water supply valve and carefully check
for leaks.
7) RO System Flush Instructions:
Prefilter: Flush at least 2 gallons of water through filter
before use.
Postfilter: Flush at least 2 gallons of water through fil-
ter before use.
RO Membrane Cartridge: Run product water to drain for
24 hours.
C. REPLACINGTHEROMEMBRANECARTRIDGE
The life of the RO membrane cartridge depends on the
local water conditions and proper maintenance, e.g., regular
filter changes. The maximum recommended service life is
36 months. Unlike the filter cartridges, the RO membrane
cartridge life is not determined by the amount of water used
because of its self-cleaning feature.
