Regenerant Line Connection - Autotrol 255 Manuel D'utilisation

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 ope-
ration.
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.

NOTE: Be sure to use a 3/8 inch NPT
plumbing connection when attaching
regenerant line to the Performa valve.
NOTE: When installing a 3-cycle filter (253, 263, or 273 valve) use a cap on
the regenerant line connection to prevent water seepage from the port. See
Parts and Accessories section for part number.
An aircheck must be used in the regenerant line when installing a Performa
valve.
