Installation / Electrical
LOCATION OF UNIT
Locate the pump as near the liquid source as possible,
using a short, direct suction pipe. Keep the static suction
lift (vertical distance between the center line of the
pump and the liquid level) to a minimum. Mount the
pump on a solid, level foundation, which provides a
rigid and vibration-free support. The pump should be
located where it is readily accessible for service and
maintenance. The pump should be protected against
flooding and excessive moisture.
PIPING
Both suction and discharge piping should be
independently supported at a point near the pump to
avoid strains being placed on the pump. Start all piping
at pump to avoid strains left by a gap at last connection.
SUCTION PIPING
The suction pipe must be kept free of leaks. The suction
pipe must have a gradual slope upward to the pump.
Avoid any fittings which may cause an air trap. On units
that have a suction fitting, a check valve is a built-in
feature and no foot valve is required.
DISCHARGE PIPING
A gate valve and union should be installed in the
discharge line. For removal of the pump for service,
close the gate valve, and disconnect at union.

ELECTRICAL

Hazardous voltage. Can shock, burn, or
cause death. Ground pump before connecting to power
supply.
Disconnect power at service panel be fore
connecting motor. Single phase motors come factory
wired for 230 volt operation. Do not alter wiring in
single phase motors. Match motor voltage to power
supply voltage. Do not connect three phase motors to
single phase power supply or single phase motors to
three phase power supply.
Ground motor before connecting to electrical
power supply.
Failure to ground motor can cause severe or fatal
electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn
OFF power to motor before working on electrical
connections.
Supply voltage must be within ±10% of nameplate
voltage. Incorrect voltage can cause fire or
seriously damage motor and voids warranty. If in doubt
consult a licensed electrician.
Use wire size specified in Table I. If possible,
connect pump to a separate branch circuit with no
other appliances on it.
WIRING
Step 1. Install, ground, wire and maintain this pump
in ac cordance with your local electrical code
and all other codes and ordinances that apply.
Consult your local building inspector for local
code information.
Step 2. Ground the pump permanently using a wire
of size and type specified by local or National
Electrical Code or Canadian Electrical Code.
Do not ground to a gas supply line.
Step 3. Connect ground wire first. Connect to ground
first, then to green grounding terminal provided
(identified as GRD or
connection to this terminal. Do not connect
motor to electrical power supply until unit is
permanently grounded; otherwise serious or fatal
electrical shock hazard may be caused.
Step 4. For best ground connection, connect to a
grounded lead in the service panel or to a metal
underground water pipe or well casing at least
10 ft. long. If plastic pipe or insulated fittings are
used, run ground wire directly to the metal well
casing or use ground electrode furnished by the
power company.
