Changing The Filter Cartridges

Your RO module is equipped with valve heads which will
automatically turn off the water supply to each filter when the
filter is released, thus you do not need to turn off the incoming
water supply at the Adapt-a-Valve. The RO faucet must be
off when filters are replaced. To make the removal of the filter
cartridges easier, the heads & cartridges may be swiveled up to
90 degrees as shown in the pictures to the right.
To buy replacement part(s) please visit the retail store or their
website or contact Watts retail customer service at

Membrane Replacement (2 - 5 Years)
Replace:
• Reverse Osmosis Membrane Filter ...H2O-F16 (P/N 88005218)
Capacity- 2-5 years
Membranes have a life expectancy between 2 and 5 years,
depending on the incoming water conditions and the amount the RO
system is used. This reverse osmosis membrane is critical for effective
reduction of total dissolved solids (TDS). The product water should be
tested periodically to verify that the system is performing satisfactorily.
Normally, a membrane would be replaced during a semiannual or
annual filter change. However, if at any time you notice a reduction in
water production or an unpleasant taste in the reverse osmosis water,
it could be time to replace the membrane. Pure H2O recommends
replacing the membrane when TDS reduction falls below 75%.
A water sample may be sent to Pure H2O for a free diagnosis of
your membranes performance. To send a water sample, use 2 clean
containers and fill 1/2 cup of tap water in one container and 1/2 cup
of RO water in 2nd container. Clearly label each sample. Send the
samples to the address listed on the cover of this manual attention
"Water Samples". Pure H2O will test the water and mail or call you
with the results.
Step 1
- Place a towel under the RO module to catch any
excess water that may drip out from the filters during
the changeover.
Step 2
- To remove a filter cartridge: Push & hold the button
on the valve head above the filter. Twist filter
counter-clockwise for about 45 degree while pulling
downward (from the head). Release button and
discard old filter.
Step 3
- To install a filter cartridge: Remove the seal cap and
insert the cartridge into the filter head, push upward
and twist the filter clock-wise for about 45 degree
until you hear an audible "click" (the button does not
need to be pressed to install new filters)
This reverse osmosis system contains a replaceable component
(the RO membrane) which is critical to the efficiency of the system.
Replacement of this reverse osmosis membrane should be with
H2O-F16 as defined by Pure H2O to assure the same efficiency
and contaminant reduction performance.
