Hazardous voltage. Can shock, burn,
or kill. Connect ground wire before connecting
power supply wires. Use the wire size (including
the ground wire) specified in the wiring chart.
If
possible, connect the pump to a separate branch cir-
cuit with no other appliances on it.
Explosion hazard. Do not ground to
a gas supply line.
Figure 14 – Motor wiring connections through Pressure Switch. Match motor voltage to line voltage.
Your Motor Terminal Board (under the motor end cover)
and Pressure Switch look like one of those shown below.
Convert to 115 Volts as shown. Do not change motor wiring
if line voltage is 230 Volts or if you have a single voltage
motor. Connect power supply as shown for your type of
switch and your supply voltage.
