Wiring Connections - Simer 3105P Owner's Manual

Electrical
Disconnect power before working on pump, motor, pressure switch, or wiring.
MOTOR SWITCH SETTINGS
NOTE: 1/2 HP motors are wired for 115 volts only, and have no motor wiring to change.
3/4 HP or 1 HP motor terminal boards (located under the motor end cover) should look like one of those below.
If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor wiring
if line voltage is 230 volts, or if you have a single voltage motor.
Never wire a 115 volt motor to a 230 volt line.

Voltage is factory set to 230 volts. To change to 115 volts:
1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in the
dial window as shown in Figure 7.

3. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in Figure 6.
4. Attach the ground wire to the grounding connections
as shown in Figure 6.
5. If there are other wires, they should be capped.
6. Reinstall the Motor end cover.

shown. Do not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in compli-

Canadian Electrical Code (CEC), as applicable, and with
all local codes and ordinances that apply. Consult your
local building inspector for code information.
