MOTOR SWITCH SETTINGS
NOTE:
The motor is wired for 115 volts only, and has no
motor wiring to change.
Never wire a 115 volt motor to a 230 volt
line.
WIRING CONNECTIONS
Fire hazard.
Incorrect voltage can cause a
fire or seriously damage the motor and voids the warranty.
The supply voltage must be within ±10% of the motor
nameplate voltage.
Do not alter the wiring in the motor.
Install, ground, wire, and maintain your pump in compli-
ance 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.
Connection Procedure:
1. Connect the ground wire first. The ground wire must be
a solid copper wire at least as large as the power sup-
ply wires.
2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding pro-
tection. If the pressure switch is not connected to the
motor, connect the green ground screw in the switch to
the green ground screw under the motor end cover. Use
a solid copper wire at least as large as the power sup-
ply wires.
3. Connect the ground wire to a grounded lead in a ser-
vice panel, to a metal underground water pipe, to a
metal well casing at least ten feet (3M) long, or to a
ground electrode provided by the power company or
the hydro authority.
4. Connect the power supply wires to the pressure switch
as shown in Figure 4:
4A. Make sure power is off.
4B. Make sure you are connecting the pump to a 115
volt circuit.
4C. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in
Figure 4.
4D. Attach the ground wire to the grounding connec-
tions as shown in Figure 4.
4E. If there are other wires, they should be capped.
4F. Reinstall the motor end cover.
Hazardous voltage. Can shock, burn, or kill.
Connect ground wire before connecting power supply
wires. Use the wire size (including the ground wire) spec-
ified in the wiring chart.
If possible, connect the pump to
a separate branch circuit with no other appliances on it.
Explosion hazard. Do not ground to a gas
supply line.
Disconnect power before working on pump, motor, pressure switch, or wiring.
