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 mainte-
nance. The pump should be protected against flooding
and excessive moisture.
PIPING
Both suction and discharge piping should be indepen-
dently 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 fea-
ture and no foot valve is required.
DISCHARGE PIPING
A gate valve and union should be installed in the dis-
charge 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 before
connecting motor. Single phase motors come factory
wired for 230 volt operation. Do not alter wiring in sin-
gle 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 seri-
ously damage motor and voids warranty. If in doubt
consult a licensed electrician.
Use wire size specified in Table I. If possible, con-
nect pump to a separate branch circuit with no
other appliances on it.
WIRING
Step 1. Install, ground, wire and maintain this pump in
accordance 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
tion 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 ground-
ed lead in the service panel or to a metal under-
ground 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.
