Attach plastic top screen to the under‐side of the 5900‐BT 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. It may twist on clockwise or counter‐clockwise.
8. Add a small amount of silicone grease to both O‐rings (only O‐rings, not tank thread) on the
bottom of the control valve and screw on 5900BT control valve carefully.
9. Do not lubricate tank threads or any other fittings other than O‐rings. Do not use pipe‐joint
compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases on tank threads.
10. If you pull up the distributor tube up after the gravel and media are in the tank (upon initial
install or any time after, for service, etc.), it
must be re‐seated. It is usually possible to do
this by spraying water down the distributor
tube with a garden hose while pushing on the
end of the tube. If this does not work, you
must empty the tank completely and start
over.
11.
Do not hard pipe the drain line with PVC or
copper, use flexible tubing.
If you use hard
PVC piping for the drain line,
you must able
to remove the hard drain piping and attach
flexible tubing for testing purposes.
12.
Make sure the drain tubing is firmly clamped
to the barbed fitting with a hose clamp to
prevent leaks or blow-offs.
