Installer Manual 255-LOGIX 740-760 - Installation
Ref. MKT-IM-001 / C - 08.10.2019 31 / 76
Note
Waste connections or the drain outlet shall be designed and constructed to provide
connection to the sanitary waste system through an air-gap of 2 pipe diameters or 25.4 mm
(1"), whichever is larger.
Caution
Never insert the drain line directly into a drain, sewer line or trap. Always allow an air gap
between the drain line and the wastewater to prevent the possibility of sewage being back-
siphoned into the softener.
5.9. 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.
