INSTALLATION

INSTALLATION OVERVIEW

Install pump on a hard, level surface (cement, asphalt, etc.).
Never place pump directly on earth, clay, or gravel surfaces.
Basinmustbeatleast18"indiameterand30"deep.
WARNING
Risk of electrical Shock. Can burn or kill.
Disconnect power to the pump before removing or working on it.

PUMP HANDLING

• Always use the pump handle for lifting/lowering pump
(Figure 1).
• Disconnect power to pump before doing any work on it or
attempting to remove it from sump.
• Attempting to lift or support the pump by power cord
can damage cord and connections, causing damage that
exposes bare wires and the possibility of fire or electrical
shock.
• Lifting or supporting pump by power cord will void warranty.
PIPING
Piping must not be smaller than pump discharge.
The rate of flow in the discharge pipe must keep any solids
present in suspension in the fluid. To meet minimum flow, size
pipe as outlined in Table 1 below.

Pipe Size:
2"(51mm)
2-1⁄2"(64mm)
3"(76mm)
Usea2"(51mm)minimumcheckvalveinpumpdischargeto
prevent backflow of liquid into sump basin. The check valve
should be a free flow valve that will easily pass solids. Be sure
check valve installation complies with local codes.

Minimum Flow Rate:
21 GPM (79.5 L/M)
30 GPM (113.5 L/M)
48 GPM (182 L/M)
For best performance of check valve when handling solids, do
not install it with discharge more than 45° above the horizontal.
Do not install check valve in a vertical position as solids may
settle in valve and prevent opening on startup.

ELECTRICAL INSTALLATION

Hazardous voltage. Can shock, burn, or cause
WARNING
death. When installing, operating, or servicing this pump, follow
safety instructions below.
• DO NOT splice the power cord, submerge electrical cord
plug, or use extension cords.
• DO NOT handle or service pump while it is connected to
power supply.
• DO NOT operate pump unless it is properly grounded. Power
cord is a 3-wire conductor with 3-prong grounding-type
plug. Do not modify cord or plug. When using with plug-in
receptacle, plug pump into a 3-wire, grounded, grounding-
type receptacle only. Connect pump according to all
applicable codes.
• Ensure that the power supply information (voltage/hertz/
phase) on pump motor nameplate matches incoming power
supply exactly. Install pump according to all electrical codes
that apply.
• For automatic operation, plug or wire pump into an
automatic float switch or pump controller. For continuous
operation, plug directly into an electrical outlet or wire
directly into switch box.
• Connect pump to its own individual branch circuit with
nothing else on the circuit. For fuse and circuit breaker
requirements, refer to the Specifications section of this
manual..
• An automatic overload protector in the motor will protect
motor from burning out due to overheating/overloading.
When motor cools down, protector automatically resets and
starts motor.
• If overload trips frequently, check for cause. It may be a
stuck impeller, wrong/low voltage, or an electrical failure in
the motor. If an electrical failure in the motor is suspected,
have it serviced by a qualified professional.
• DO NOT allow pump to run in a dry sump. It will void the
warranty and may damage the pump.
