the swivel-T connector. Remember to avoid crimping and excessive tubing length. Open the valve

on top of the storage tank by moving the handle parallel to the tubing.

g) Open the chrome faucet on the sink top.

h) Turn on the cold water supply. In approximately 20 minutes you will see water beginning to drip

from the chrome faucet. Close the faucet and allow the storage tank to ﬁ ll. Check for leaks and

gently tug on all connections to assure a tight ﬁ t.

Operating Notice

The initial ﬁ lling of the storage tank will probably seem slow. The Reverse Osmosis element has been

factory tested for rejection and ﬂ ow, however, the element when new is generally “tight.” The water

cavity of the pressure vessel and deionization module is initially empty and must ﬁ ll before pure water

will appear in the tank. After leaving the unit connected and running for 24–36 hours the storage tank

should be completely full.

Your PWS™ BEV-300 system is easy to operate because the tank auto shut-off does all the work. When

the storage tank is nearly full the auto shut-off will stop the ﬂ ow of feed water to the system. Similarly,

when the water in the tank drops below a certain level, the auto shut-off will re-open the feed water sup-

ply allowing the system to reﬁ ll the storage tank.

(The auto shut-off mechanism relies on a pressure differential between the feed water and product water

to operate. For this reason, the system will “turn on” before the tank is completely empty, and will “turn

off” before the tank is completely full.)

Flushing

Flushing is the single most important maintenance function you will need to perform to keep your system

operating at peak efﬁ ciency. This simple operation only takes a few minutes, yet makes a great difference

in the quality of the water your unit produces, and extends the service life of the RO membrane.

a) Flushing the RO membrane can only be accomplished when the system is ﬁ lling (see pressure

gauge). Allow the storage tank to empty until you hear the water ﬂ owing then begin the ﬂ ushing

procedure.

b) Move the black handle on the ﬂ ush valve parallel to the RO pressure vessel. This will open the

ﬂ ush valve and allow water to rapidly ﬂ ow across the surface of the RO membrane, washing away

contaminants which, if allowed to accumulate, might clog the pores of the membrane.

c) Set a kitchen timer so you do not forget to return the ﬂ ush valve to the closed position.

Flushing the unit for 10 minutes every two weeks is ideal.

In the event you forget to ﬂ ush the system for an extended period of time, you can perform an exhaus-

tive ﬂ ush of the membrane by leaving the ﬂ ush valve open for 20 minutes.

If your unit has not been operational for several days (e.g. while you are on vacation), drain the storage

tank (use the water for watering plants, etc.) then ﬂ ush the membrane for 5-10 minutes as described

above.
