Overflow Line Connection - Pentair Autotrol 255 Installer Manual

Overflow line connection

In the event of a malfunction, the brine tank overflow fitting will direct "overflow" to the drain instead
of spilling on the floor. This fitting should be on the side of the cabinet or brine tank. Most tank
manufacturers include a post for the tank overflow connector.
To connect the overflow line, locate the hole on side of tank. Insert overflow fitting into tank and
tighten with plastic thumb nut and gasket as shown below. Attach a length of 12.7 mm (1/2") I.D.
tubing (not supplied) to fitting and run to drain.
Do not elevate overflow higher than overflow fitting.
Do not tie into drain line of controller unit. Overflow line must be a direct, separate line from overflow
fitting to drain, sewer or tub. Allow an air gap as per drain line instructions.
Caution
Floor drain is always recommended to avoid flooding in case of overflow.
