Installation, Operation & Maintenance Manual
SECTION 2 - INSTALLATION AND OPERATION
2.1 INSTALLATION
Carefully unpack the pump and select a mounting
location in the Plenum area (
see Figure 1
). The
pump must be level and the inlet must be below the
lowest drain, either coil or furnace. If wall or case
mounting, use the mounting tabs on either side of
the reservoir to secure the pump.
2.1.1 Piping
Run flexible tubing or pipe from the evaporator and
furnace to the pump. Connect to either inlet barbed
fitting. Make sure the pipe does not interfere with
the float. If barbed fitting is not used, cut an angle
on the inlet pipe so that it doesn’t close off against
the bottom of the pump.
Connect tubing to the check valve. Extend this
tubing straight up as high as necessary. (Do not
extend this tubing past the head/GPH of the pump
installed). Do not kink the tubing, as this will block
the flow. From this high point, slope the discharge
tubing downward to a point above the drain, then
turn down and extend to a point below or level
with the bottom of the condensate pump. If it is not
possible to slope the discharge tubing downwards,
make an inverted “U” trap directly above the pump
at the highest point (
Figure 2
).
