To Convert 115 Volts to 230 Volts, Plug-in type
(see Figure 6).
1. Unplug the motor.
2. Loosen the two screws on the end of the motor.
Gently pull the canopy from the motor.
NOTICE: Do not pull or jerk wires.
3. Connect the green (or bare copper) ground wire to
the green ground screw first (see Figure 6). Use a
solid copper wire at least as large as the power
supply wires.
4. Pull the plug straight out from the terminal board,
from 115 Volt socket (Figure 6).
5. Plug in again with arrow on plug pointing to 230
Volts.
6. Change is complete.
NOTICE: 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.
To Check For Proper Rotation – 3 Phase Motors
Risk of electrical shock.
1. Be sure power is disconnected to motor when
working on electrical connections.
2. Remove the motor end cover, exposing motor shaft.
Momentarily start pump. If hookup is correct, the
shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to
the starter. The rotation will now be correct.
GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and
type specified by local or National Electrical Code.
Models with factory installed cord and plug:
Risk of electric shock. This equipment is
only for use on 115V and is equipped with an approved
3-conductor cord and 3-prong, grounding-type plug. To
reduce the risk of electric shock, be certain that it is
connected to a properly grounded, grounding-type
receptacle. Do not modify or remove plug. Make sure
pump circuit meets National Electrical Code. To avoid
dangerous electrical shock hazard, keep cord dry at all
times.
Models without cord and plug:
1. Connect ground wire first. Connect the ground first,
then to green grounding terminal provided under
motor canopy (see Figure 5) identified as GRD.
Make ground 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.
2. 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.
MAINTENANCE
Pump Disassembly
Hazardous voltage. Can shock, burn or
cause death. Disconnect power to pump before
servicing.
Tools required:
1. 7/16” open end wrench (2 required).
2. Flat blade screwdriver with insulated handle.
3. Work bench with vise recommended.
4. Pliers or similar tool.
5. Pipe wrench.
