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. 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 4
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.
