READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for
one of the following signal words and be alert to the
potential for personal injury:
warns about hazards that will cause serious
personal injury, death or major property damage if
ignored.
warns about hazards that can cause serious
personal injury, death or major property damage if
ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The label NOTICE indicates special instructions which
are important but not related to hazards.
Carefully read and follow all safety instructions in this
manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
1. Read this manual carefully. Failure to follow these
instructions could cause serious bodily injury and/or
property damage.
2. Check your local codes before installing. You must
comply with their rules.
3. Vent sewage or septic tank according to local codes.
4. Do not install pump in any location classified as
hazardous by National Electrical Code, ANSI/NFPA
70-1990.
Hazardous voltage. Can shock, burn or
cause death. During operation, the pump is in water.
To avoid fatal shocks, proceed as follows if pump needs
servicing:
5A. Disconnect power to outlet box before unplugging
pump.
5B. Take extreme care when changing fuses. Do not
stand in water or put your finger in fuse socket.
5C. Do not modify cord and plug. When using cord and
plug, plug into a grounded outlet only. When wiring
to a system control, connect pump ground lead to
system ground.
6. Do not run pump dry. Dry running can overheat
pump, (causing burns to anyone handling it) and will
void warranty.
7. Pump normally runs hot. To avoid burns when ser-
vicing pump, allow it to cool for 20 minutes after
shut-down before handling it.
8. In normal service, motor should not need oiling.
Motor has been filled at the factory with a special oil.
INSTALLATION
(See Figure 1 for Typical Installation instructions.)
Pump must be level when operating. If
motor is tilted, internal start/run switch may overheat and
damage motor.
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. See “Cord Lift Warning”
on Page 4. Do not hang pump from discharge pipe or
power cord.
1. Install the pump on a solid, level foundation, or in a
sump pit constructed of tile, concrete, steel or plas-
tic. The recommended minimum diameter of the
sump pit is 18" (46cm) diameter and the minimum
recommended depth is 30" (76cm). Check local
codes for approved materials.
NOTICE: Pump should not be installed on clay, earth
or sand surfaces. Clean the area around the pump of
small stones and gravel which could clog the pump.
Keep the pump inlet screen clear.
2. Thread a 2” discharge pipe into the pump 2” NPT
discharge port. Be careful to avoid stripping or cross-
ing threads.
Piping – Effluent Applications
(3/4" or Less Solids)
Piping must be 1-1/2" minimum to carry volume of
pump discharge. Check local codes to determine if a
check valve is required in your system. In cold climates,
check valves are not used to prevent effluent from freez-
ing in piping.
