Overflow Line Connection
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.
