Overflow Line Connection - Pentair FLECK 3150 NXT Installer Manual

Installer manual Fleck 3150 NXT/NXT2 - Installation
Secure the end of the drain line to prevent it from moving.
Info
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
100.6 mm (4"), 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 waste water to prevent the possibility of sewage
being back-siphoned into the softener.

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 brine tank.
Most brine tank manufacturers features a pre-drilled hole for the tank overflow
connector.
To connect the overflow line, locate the hole on the side of the tank. Insert the overflow
fitting into the tank and tighten with plastic thumb nut and gasket as shown below.
Attach a 25.4 mm (1") I.D. tubing (not supplied) to fitting and run to drain.
Do not elevate overflow higher than overflow fitting.
Do not tie into the drain line of the controller unit. The 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.
