Connection diagram for dual voltage, single-phase
motors. Your dual-voltage motor’s terminal board
(under the motor end cover) will look like Figure 3. If
your power supply is 115 volts, use a flat-bladed screw-
driver or a nut driver to change the dial from 230 volts
to
115 volts (see Figure 3). Connect power supply wires
to L1 and L2.
Note: For 3-phase motors, or if motor does not match
these pictures, follow the connection diagram on the
motor nameplate.
Hazardous voltage. Can shock, burn,
or cause death. Disconnect power to motor before
working on pump or motor. Ground motor before
connecting to power supply.
WIRING
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 electri-
cal connections.
Supply voltage must be within ±10% of name-
plate voltage. Incorrect voltage can cause fire or
damage motor and voids warranty. If in doubt con-
sult a licensed electrician.
Use wire size specified in Wiring Chart (Page 7).
If possible, connect pump to a separate branch cir-
cuit with no other appliances on it.
Wire motor according to diagram on motor
nameplate. If nameplate diagram differs from dia-
grams above, follow nameplate diagram.
Step 1. Install, ground, wire and maintain this pump in
accordance with electrical code requirements.
Consult your local building inspector for infor-
mation about codes.
Step 2. Provide a correctly fused disconnect switch for
protection while working on motor. Consult
local or national electrical codes for switch
requirements.
Step 3. Disconnect power before servicing motor or
pump. If the disconnect switch is out of sight of
pump, lock it open and tag it to prevent unex-
pected power application.
