Risk of electric shock. 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 dedicated branch
circuit (one with no other appliances on it).
Risk of explosion. Do not ground to a gas supply line.
WARNING: Risk of fire. 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.
NOTICE: For model WPD07501K / WPD10001K, motors voltage were set for 230 V. If necessary, reset the motor to the
desired voltage, as shown. Install, ground, wire, and maintain your pump in compliance 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.
