WHEN SHiPPED.*
To change the motor to use 115 volts:
1. Turn off power
2. Remove the back motor cover.
3. Use a screwdriver or 1/2" wrench and turn the
voltage selector dial counterclockwise until 115
shows in the dial opening.
4. Reinstall the motor cover.

figure 6: Motor Set for 115 volt Operation.
* Models with power cords are pre-wired for 115 volts.
This includes models MGP7C and MGP7D.
ElEctrical
Ground motor before connecting to electrical
power supply.
failure to ground motor can cause severe or
fatal electrical shock hazard.
Explosion 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 serious damage to motor and voids
warranty. if in doubt consult a licensed electrician.
Use wire size specified in Wiring chart (table ii,
Page 6). if possible, connect pump to a
separate branch circuit with no other appliances on it.
Wire motor according to diagram on motor
nameplate. if nameplate diagram differs from
diagrams above, follow nameplate diagram.
for all 3-phase Motors: Follow the wiring
diagram on the motor junction box or on the

1. Install, ground, wire and maintain this pump in
compliance with the National Electrical Code (NEC)
or the Canadian Electrical Code (CEC) and with all
local codes and ordinances that apply. Consult your
local building inspector for local information.
2. Make sure that the voltage, frequency and phase
(single phase or three phase) of the power supply
agree with that stamped on the motor nameplate. If
in doubt, check with the power company.
3. Some models are equipped with three phase
motors. Three phase motors require magnetic
starters and can run in either direction, depending
on how they are connected to the power supply.
NOticE: Dual voltage motors without cords are factory
wired for 230 volts. If necessary, reconnect the motor
for 115 volts, as shown. All cord connected motors are
wired for 115 volts (see Page 6). Do not alter the wiring
in single voltage motors.
Install, ground, wire, and maintain your pump in
comliance with the National Electrical Code (NEC) or
the Canadian Electrical Code (CEC), as applicable, and
with all local codes and ordinances that apply. Consult
your local building inspector for code information.
NOticE: Clamp the power cable to prevent strain on
the terminal screws.
NOticE: your Motor terminal Board (under the
motor end cover) looks like the board shown at
left. Do not change motor wiring if line voltage is
230 volts. connect power supply as shown for your
supply voltage.
