This reverse osmosis system contains a replaceable compo-

nent (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 perfor-

mance.
Note: Your RO module is equipped with valved 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 faucet must be off

when filters are replaced.
Step A – Place a towel under the RO module to catch any excess

water that drips out from the filters during the changeover .

Step B – To make the removal of the

filter housings easier, the heads

and housings may be lifted up

to 90° as shown in the pictures

to the right . Starting with the

sediment filter, lift the cartridge

up to 90° . Rotate the cartridge

⁄

turn counterclockwise,

remove and dispose of used cartridge .

Step C – Make sure to remove the

cap off of the new replace-

ment filter . Insert the new filter

cartridge into the head and

rotate it clockwise

⁄

turn until

it stops . Return cartridge to the

vertical position .

Step D – Repeat this procedure for the

2nd filter cartridges . When

finished, flush your tank

completely once to remove

any natural carbon fines from

the RO system . Check over

the next 24 hours to ensure no

leaks are present .
