Overflow Line Connection - Autotrol 255 Manuel D'utilisation

NOTE: Waste connections or drain outlet shall be designed and constructed
to provide for connection to the sanitary waste system through an air-gap of
2 pipe diameters or 1 inch (22 mm) whichever is larger.
WARNING: Never insert drain line directly into a drain, sewer line, or trap
(Figure 8). Always allow an air gap between the drain line and the wastewater
to prevent the possibility of sewage being back-siphoned into the conditioner.

Overflow Line Connection

(not used with 3-cycle filter system)
In the event of a malfunction, the regenerant TANK OVERFLOW will direct "overflow" to the
drain instead of spilling on the floor. This fitting should be on the side of the cabinet or
regenerant tank. Most tank manufacturers include a post for the tank overflow connector.
To connect the overflow line, locate hole on side of tank. Insert overflow fitting into tank
and tighten with plastic thumb nut and gasket as shown (Figure 9). Attach length of
1/2-inch (1.3-cm) I.D. tubing (not supplied) to fitting and run to drain. Do not elevate over-
flow line higher than overflow fitting.
Do not tie into drain line of control 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.
