GASBOY Series 70 & 1820
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,
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.
