2. Install discharge plumbing. When using rigid pipe,
use plastic pipe. Wrap thread with PTFE pipe thread
sealant tape. Screw pipe into discharge fitting hand
tight +1 – 1-1⁄2 turns.
note:
Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics.
3. To reduce motor noise and vibrations, a short length
of rubber hose (1-7⁄8" I.D., e.g. radiator hose) can
be connected into discharge line near pump using
suitable clamps.
4. Install an in-line check valve to prevent flow
backwards through pump when pump shuts off.
5. Thread vent pipe into 1-1⁄2" NPT black vent fitting
in basin cover. Pipe should not extend into basin.
Connect vent pipe to sewer vent system.
6. Power Supply: Pump is designed for 115 V., 60 Hz.,
operation and requires a minimum 15 amp individual
branch circuit. Both pump and switch are supplied
with 3-wire cord sets with grounding-type plugs.
Switch plug is inserted directly into outlet and pump
plug inserts into opposite end of switch plug.
Hazardous Voltage.
Pump should always be
electrically grounded to a suitable electrical ground such
as a grounded water pipe or a properly grounded metallic
raceway or ground wire system. Do not cut off round
ground pin.
7. If pump discharge line is exposed to outside sub-
freezing atmosphere, portions of line exposed must
be installed so any water remaining in pipe will drain
to the outfall by gravity. Failure to do this can cause
water trapped in discharge to freeze which could result
in damage to pump.
8. After piping and check valve have been installed, unit
is ready for operation.
9. Check operation by filling sump with water and
observing pump operation through one complete
cycle.
risk of flooding.
Failure to make this
operational check may lead to improper operation,
premature failure, and flooding.
maintenance
risk of electric shock.
Make certain that the
pump is unplugged before attempting to service or remove
any component.
risk of electric shock.
Do not handle a
pump or pump motor with wet hands or when standing
on wet or damp surface, or in water.
1. Keep pump inlet screen clear.
2. Shaft seal depends on water for lubrication. Do not
operate pump unless it is submerged in water as seal
may be damaged if allowed to run dry.
3. Motor is equipped with automatic reset thermal
protector. If temperature in motor should rise unduly,
switch will cut off all power before damage can be
done to motor. When motor has cooled sufficiently,
switch will reset automatically and restart motor. If
protector trips repeatedly, pump should be removed
and checked for cause of difficulty. Low voltage, long
extension cords, clogged impeller, very low head
or lift, etc., could cause cycling. Refer to Trouble
shooting Guide on Page 6 for additional information.
4. Periodically inspect pump, system components, and
sump for debris and foreign objects. Keep sump free of
all refuse. Perform routine maintenance as required.
pump cleaning
note:
Attempting to disassemble motor will void
warranty.
1. Use the pump ring to lift pump out of basin and place
pump on a clean level surface.
risk of electrical shock.
Shock can burn or
kill. Do not lift pump by power cord.
2. To clean impeller, remove eight screws holding
baseplate to motor assembly. Clean impeller as
necessary.
3. Re-install baseplate and screws.
4. Use pump ring to replace pump in basin.
