Membrane Replacement

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 lter 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 Premier recommends replacing the membrane when TDS reduction falls below

75%.

Step 1

Step 3

Remove the horizontal membrane housing on top of the unit by

turning it counter clockwise to loosen.

Turn off the incoming water supply to the RO by turning the needle

valve on the adapt-a-valve clockwise until it stops. (Follow the green

tube away from the RO system to nd the adapt-a-valve.)

Pull rmly on the yellow RO membrane to remove it from the housing

and discard.

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 into the cap. Twist the membrane as you push it rmly into

the manifold.

Step 5

Step 6 Replace the membrane housing onto the cap by turning clockwise.

Tighten securely.

A water sample may be sent to Watts Premier for a free diagnosis of your membranes

performace. To send a water sample, use two (2) clean containers and ll 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 Premier will test the water and mail or call you with the results.

Note:

Open the RO Faucet and allow water to drain from the tank until it

is completely empty.

Step 2

Before re-installing the membrane housing back on to the

system, check O-ring on the housing to make it is still in

place and lubricate with water soluble lubricant.

Caution:

This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the efciency of

the system. Replacement of this reverse osmosis membrane should be with one of identical specications as dened by

Watts Premier to assure the same efciency and contaminant reduction performance.
