Regenerant Line Connection
(not used with 3-cycle filter system)
The regenerant line from the tank connects to the valve. Make the
connections and hand tighten. Be sure that the regenerant line is secure and
free from air leaks. Even a small leak may cause the regenerant line to drain
out, and the conditioner will not draw regenerant from the tank. This may also
introduce air into the valve causing problems with valve operation.
Most installations utilize a tank check valve. This is not necessary when using
the 255 valve with the built-in aircheck. Using a tank check valve with the 255
valve with aircheck will result in premature checking of the aircheck valve,
before the tank is empty.
