Installation and Operation
17. Do not handle pump or pump motor with wet
hands or when standing on wet or damp surface,
or in water.
Hazardous voltage can shock, burn or
kill. If your basement has water or moisture on
floor, do not walk on wet area until all power has
been turned off. If shut-off box is in basement, call
electric company or hydro authority to shut-off
service to house, or call your local fire department
for instructions. Remove pump and repair or re-
place. Failure to follow this warning can result in
fatal electrical shock.
Do not lift pump by power cord.
FLOAT SWITCH INSTALLATION
See the Switch Assembly instructions on Page 4.
INSTALLATION
1. Install pump in sump pit with minimum diameter
of 10" (254mm). Sump depth should be 10"
(254mm). Construct sump pit of tile, concrete,
steel or plastic. Check local codes for approved
materials and for proper installation.
2. Install pump in pit so that switch operating
mechanism has maximum possible clearance.
3. Pump should not be installed on clay, earth or
sand surfaces. Clean sump pit of small stones
and gravel which could clog pump. Keep pump
inlet screen clear.
NOTICE: Do not use ordinary pipe joint
compound on plastic pipe. Pipe joint compound
can attack plastics.
4. Install discharge plumbing. Use rigid plastic pipe
and wrap threads with 1
into pump hand tight plus 1-1/2 turns.
Risk of flooding. If a flexible
discharge hose is used, make sure pump is
secured in sump to prevent movement. Failure
to secure pump may allow pump movement,
switch interference and prevent pump from
starting or stopping.
5. To reduce motor noise and vibrations, a short
length of rubber hose (1-7/8" (47.6mm) I.D., e.g.
radiator hose) can be connected into discharge
line near pump using suitable clamps.
6. Install an in-line check valve or an in-pump check
valve to prevent flow backwards through pump
when pump shuts off.
NOTICE: Check valves should be equipped with
an air bleed hole to prevent airlocking pump. If
not, drill a 1/8" (3.2 mm) hole in discharge pipe
just above where the discharge pipe screws into
the pump discharge. Be sure the hole is below the
waterline and the check valve to prevent air locks.
7. Power Supply: Pump is designed for 115 V.,
60 Hz., operation and requires a minimum
15 amp individual branch circuit. Both pump and

Teflon TM tape. Screw pipe
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.
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.
8. If pump discharge line is exposed to outside sub-
freezing atmosphere, portion 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.
9. After piping, check valve and float switch have
been installed, the unit is ready for operation.
10. Check the pump operation by filling sump with
water and observing pump operation through one
complete cycle. For switch settings see the Electrical
and Switch Specifications chart on Page 2.
Failure to make this operational
check may lead to improper operation,
premature failure, and flooding.
OPERATION
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. 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.
2. 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 as to
cause of difficulty. Low voltage, long extension
cords, clogged impeller, very low head or lift, or
a plugged or frozen discharge pipe, etc., could
cause cycling.
3. Pump will not remove all water. If operating a
pump manually, and suddenly no water comes
out of the discharge hose, shut off the unit
immediately. The water level is probably very low
and the unit has broken prime.
NOTICE: For continuous operation, water depth
must be at least 5" (127mm) to prevent the
motor from overheating. A fully submerged
pump is preferred for proper cooling when a
pump runs continuously.
Risk of electric shock. Before
attempting to check why unit has stopped
operating, disconnect power from unit.
