Installation 3
Fire and explosion hazard. Do not use this
pump to pump flammable or explosive liquids. Use pump
only with liquids compatible with pump component
materials. Do not use pump in explosive atmospheres.
Risk of flooding. If for any reason property
damage or personal injury can result from an inoperative
or leaking pump, an auxiliary switch backup system
and/or an alarm should be installed with pump.
INSTALLATION
Electrical shock and carbon monoxide
hazards. When mounting the pump on the side of the
furnace, make sure that the mounting holes clear the
heat exchanger and all wiring. The mounting screw for
the pump should touch only the pump reservoir flange
and the exterior sheet metal on the furnace. If in doubt or
if this is confusing, consult a qualified HVAC serviceman
or the furnace manufacturer.
Make sure that the tubing to the pump intake is fastened
securely so that it cannot come out of the pump intake
port. Check for local code requirements. You must com-
ply with codes.
Check local codes for discharge water requirements.
Run the discharge line to a point outside the house if
possible. To do this easily, you may be able to run the
condensate discharge line out through the wall along
the AC freon line. Use the existing line if possible (when
replacing an existing pump).
Clamping the plastic discharge line to the check valve
with a 1/2" hose clamp (purchase separately) will help
to keep it in place, especially with older tubing (plastic
tubing tends to harden as it gets older).
Common locations for the end of the discharge line are:
A. Out a window or along the air conditioner freon line
to the outdoors.
B. To a floor drain (leave an air gap between the end of
the tube and the drain).
C. To a laundry tub or sink (leave an air gap above the
tub drain).
