Operation
Startup Instructions
Step A -
Turn on the water supply at both the cold water supply
valve and Adapt-A-Valve . Check the system for leaks and
tighten any fittings as necessary . (Check frequently over
the next 24 hours to ensure no leaks are present) .
NOTE: If you have connected your RO system to a refrigerator
/ ice maker, make sure the ice maker is off (do not al-
low water to flow to the ice maker) until flushing (Step
D) is complete and the tank has been allowed to fill
completely. Connection from the RO to the ice maker
system should have an in-line valve installed before
the ice maker so it can easily be closed to prevent
water flowing to the ice maker during start up and peri-
odic maintenance. Your storage tank must be allowed
to fill up fully in order for the ice maker system to
work properly.
Step B -
Open the RO faucet and leave it open until water begins to
trickle out (this may take a few minutes and the water will
come out slowly) .
Step C -
Close the RO faucet allowing the storage tank to fill with
water . It may take 3 to 6 hours to fill the tank completely
depending on the production capability of the membrane,
local water temperature and water pressure .
NOTE: During the fill period you may hear water trickling
which is a normal occurrence.
Step D -
After the storage tank has filled open the RO Faucet to
flush the tank completely . You will know that the tank is
empty when the flow rate from the RO faucet is down to a
trickle . Repeat this step two more times . The fourth tank
can be used for drinking .
NOTE: The flushing process should take about a day to
complete.
NOTE: Flushing of the tank 3 times is only necessary during
the initial startup and after replacing the membrane
.
Maintenance
NOTICE
Your RO module is equipped with valved heads which will auto-
matically 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.
6 Month System Maintenance
Determine if you have an 11 inch or 13 inch product and replace
in 6 mos.

Tip: This is a good time to check the
air pressure in your storage tank. For
instructions please see page 9.
Step A -
Place a towel under the RO
module to catch any excess
water that may drip out from the
filters during the changeover .
Step B -
To remove a filter cartridge: Turn
the cartridge ¼-turn to remove .
Step C -
To install a filter cartridge:
Remove the seal cap and insert the cartridge into the valve
head with the label facing to the left (9 o’clock positon) and
then rotate it ¼-turn .
Step D -
If performing the annual maintenance, flush the first tank
full after completing the annual maintenance .
This reverse osmosis system contains a replaceable component
(the RO membrane) which is critical to the efficiency of the sys-
tem. Replacement of this reverse osmosis membrane should be
with one of identical specifications as defined by Watts to assure
the same efficiency and contaminant reduction performance.
RO Membrane Replacement
Determine if you have an 11 inch or 13 inch product and replace
in 2-5 years.

Membranes have a life expectancy between 2 and 5 years, de-
pending 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 prod-
uct water should be tested periodically to verify that the system
is performing satisfactorily.
Normally, a membrane would be replaced during a semian-
nual 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 mem-
brane. Watts recommends replacing the membrane when TDS
reduction falls below 75%.
Refer to Instructions above filter change instructions
Step A -
To change your membrane, follow the instructions for the
Annual Maintenance (previous section) . The procedure to
remove and change the membrane cartridge is the same
as all the other filter cartridges on the RO module .
Step B -
Check over the next 24 hours to ensure no leaks are
present .
