GROUNDING

To ensure proper operation of the equipment and provide the necessary safety factors, this unit must be grounded. A ground wire (preferably green) must be connected between the unit's AC junction box ground lug and the main electrical service panel. One (1) earth ground connection is required per unit. The ground rod is to be a solid, corrosion-resistant conductor and must be installed at the main electrical panel in accordance with the National Electrical Code. It should be properly tied into the ground bus strip of the panel. We recommend the neutral and ground bus strips be bonded together (unless prohibited by local codes).

THE PUMP MOTOR

Pumps are shipped from the factory with motors wired for either 115VAC, 60 cycle, or 230VAC, 50 cycle.

The pump motor is equipped with thermal overload protection. If overheated, it will shut itself off without any damage to the windings. Be sure to turn off the pump power if this occurs. As the motor cools, it will start without warning if power is on.

WIRE SIZE

The AC wire size of the AC power lines of a pump depends on the voltage at which the pump will be operated (115/230) and the distance from the circuit breaker panel to the pump. When two pumps are powered from the same breaker through the same wires, the gauge of the wires should be increased to handle the added load according to the distance from the breaker panel. Use the chart below to select the proper wire size for your installation.

Table 3-1. Wire Size

WIRE GAUGE SIZES FOR 1/3 HP MOTOR

	DISTANCE		115 VAC	230 VAC
(FEET/METERS)			GAUGE	GAUGE
25’		7m	14	14
50’		15m	14	14
100’		30m	12	12
150’		46m	10	12
200’		61m	8	12
250’		76m	8	12
300’		91m	8	12

The AC wire size for the reset complete (switch detect) line should be 14 AWG (when it is used).
