Assembly and Installation Instructions
1.
By hand, unscrew the entire CWS Plus control valve from top of tank if it was shipped screwed
on. Place distributor tube in tank if not already inside. If not already done, make sure the blue
cap is on top of distributor tube, or wrap the top of distributor tube with electrical or duct tape.
You do not want gravel or media to go down the distributor tube.
2.
Add the filter gravel that came with your order. You want the gravel to cover the bottom
distributor screen before adding the media.
3.
Next add media. The tank will be about 2/3rds full of media.
4.
Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube
when removing cap or tape.
5.
If possible at this point, fill tank completely with water. This will allow the Birm Filter media to
settle and eliminate the need of “purging” the air out of the tank later.
6.
Attach plastic top screen to the under-side of the CWS165 control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and prevents resin from being backwashed out
to drain during the regeneration cycles.
7.
Add a small amount of silicone grease or vegetable cooking oil to the tank threads and screw on
CWS165 control valve carefully. Do not use pipe-joint compound, Teflon tape, or Vaseline or
other petroleum greases to lubricate tank threads.
