Ventilation
Ventilation and drainage must be provided to prevent
damage to the motor from heat and moisture.
Freezing
The pump and all piping must be protected from freezing.
If freezing weather is forecast, drain pump or remove
completely from the system.
Water Supply
The water source must be able to supply enough water to
satisfy the capacity of the pump and water needs.
Suction Lift
Suction lift is the vertical distance from the lowest level
of the water to the pump intake. See performance charts
on page 2 and 3 to determine how far your pump can lift
water.
Horizontal Distance
The horizontal distance is the horizontal measurement
between the pump suction and the water source. This
distance may affect the ability of the pump to operate. If it
is over 100 feet, call the manufacturer for assistance at
1-800-742-5044.
Pipe And Fittings
Use galvanized steel or NSF PW Schedule 40 PVC pipe
and fittings. This material is designed for water pressure
and will seal against air and water under pressure. Do Not
Use: DWV fittings, as these are designed for drains without
pressure and will not seal properly. (Fig. 1, 2 & 3)
CAUTION: The entire system must be air and water
tight for efficient operation and to maintain prime.
Wire Size:
The wire size is determined by the distance from the power
source to the pump motor, and the horsepower rating of the
motor. See the wire chart for proper wire size.
