Electric Wiring
WARNING! Electrical wiring should be performed ONLY by a licensed electrician in compliance with local, state, and national electrical code NEC/ANSI/NFPA 70,
NFPA30, and NFPA 30A, as appropriate to the intended use of the pump. Threaded rigid conduit, sealed fittings, and conductor seal should be used. The pump
must be properly grounded. Improper installation or use of this pump can result in serious bodily injury, or death!
CAUTION! All pumps should be operated at the Rated Nameplate Voltage. Power should be supplied to the pump from a dedicated 30 amp circuit breaker.
No other equipment should be powered by this circuit. Wiring must be of sufficient size to carry the correct current for the pump. Voltage drop will vary
with distance to pump and size of wire; refer to the National Electrical Code (NEC), or local codes, for Voltage Drop Compensation to be sure you are using
the correct size wire for your application.
Wiring Procedure
WARNING! The “AUX.” wire IS A LIVE WIRE when the switch is on! The “AUX” lead wire is insulated and enclosed when shipped. DO NOT connect this wire without
first verifying the “ON” line voltage of the wire for compatibility with the equipment to be installed. Maximum amperage on this wire is 1 amp. The “AUX” wire must
be insulated and enclosed in the junction box if not used.
1. Remove the junction box cover and straighten the wires to make sure the stripped wire ends are accessible outside the junction box.
2. Connect the pump wires to the power supply lines according to the diagram. Be certain to properly insulate the connections with the appropriate wire nuts or other connectors.
Note that the ground wire MUST be connected.
3. Fold the wires back into the junction box and replace the cover, making sure the cover gasket is in place.
Use the Voltage Selector Switch on the end of the pump to select the input voltage for the pump. NOTE: The pump comes from the factory pre-set to 115V AC position.
IMPORTANT! Be certain the gasket for the cover is in place, and the screws draw the cover down tight over the junction box. There must be no gap between
the junction box and it’s cover.
