Installation • Operation
receptacle installed in accordance with codes and
ordinances that apply.
13. All wiring should be performed by a
qualified electrician.
14. Make certain power source conforms to
requirements of your equipment.
15. Protect electrical cord from sharp objects, hot surfaces,
oil, and chemicals. Avoid kinking cord. Replace or
repair damaged or worn cords immediately.
16. Do not touch an operating motor. Modern motors
can operate at high temperatures.
17. Do not handle pump or pump motor with wet hands
or when standing on wet or damp surface, or in water.
Risk of electric shock. 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 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
Models equipped with vertical switches require some
assembly. See the Switch Assembly instructions on Page
4. Models with tethered float switches are ready for use.
Installation
1. Install pump in sump pit with minimum diameter of
10" (254mm). Sump depth should be 10" (254mm)
for vertically switched models. 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 Teflon
into pump hand tight plus 1-1/2 turns.
Risk of flooding. Can cause personal
injury and/or property damage. 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 If your check valve is not equipped with
an air bleed hole to prevent airlocking pump, 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 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.
Risk of electric shock. Can shock,
burn or kill. 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.
Risk of flooding. Can cause personal
injury and/or property damage. Failure to make this
operational check may lead to improper operation,
premature failure, and flooding.
Operation
Risk of electric shock. Can shock, burn or kill.
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. Can shock, burn
