Procedure for Extended Non-Use
(More than 2 months)
Turn off the water supply by turning the knob on the Adapt-A-
Valve™ clockwise until it stops and open the RO faucet to empty the
storage tank . (Save a few ounces of RO water) . Once the storage
tank is empty, remove the membrane and place it in a sealed plastic
bag with the RO water saved earlier and store in your refrigerator .
For restart, reinstall membrane (See Page 10 for membrane installa-
tion procedure) and follow Startup Instructions on Page 8 .
Membrane Replacement
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 one
of identical specifications as defined by Watts to assure the same
efficiency and contaminant reduction performance.
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 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 . Watts recommends
replacing the membrane when TDS reduction falls below 75% .
Note: A water sample may be sent to Watts for a free diagno-
sis of your membrane performance. To send a water sample,
use two (2) clean containers and fill ½ cup of tap water in one
container and ½ cup of reverse osmosis water in 2nd container.
Clearly label each sample. Send the samples to the address
listed on the cover of this manual attention “Water Samples”.
Watts will test the water and mail or call you with the results.
Step A –
Turn off the incoming water sup-
ply to the RO by turning the knob
on the Adapt-A-Valve™ clockwise
until it stops .
Step B –
Open the RO Faucet and allow
water to drain from the tank until
it is completely empty .
Removing the Membrane
Step A –
Use a
5
⁄
8
" wrench to remove the
Green Tube fitting on the left
side of the horizontal mem-
brane housing (end with one
elbow) .
Step B –
Remove the cap from the
Membrane Housing by turning
it counterclockwise to loosen .
Note: A double sided wrench may
be purchased from Watts to aid with
loosening the cap / filter housings.
Step C –
Remove membrane hous-
ing from the holding clips .
Using a pair of pliers, grip the
PVC tube of the RO mem-
brane and pull firmly on the
membrane to remove from the
housing and discard .
Installing the Membrane
Step A –
Lubricate the O-rings on the new membrane with a water
soluble lubricant such as KY Jelly ®. Insert the end with the
two black O-rings first into the housing .
Step B –
Once membrane has been inserted into the housing, you
must take your thumbs and give a firm push to properly
seat the membrane . Replace membrane housing cap and
tighten .
Step C –
After replacing membrane housing into clips, attach the
green tube to the elbow on cap using
5
⁄
8
" wrench .
Step D –
Follow the Start Up Instructions on Page 8 .
