open. Start pump.
Slowly open valve until the desired flow rate is
reached. Final setting
must be within pump’s recommended oper-
ating range.
OPERATION
1. The pump must be submerged at all times during normal opera-
tion.
Do not run pump dry.
2. Make sure that the float switches are set so that the pump stops
before the pump runs dry or breaks suction. If necessary, adjust
float switches to achieve this.
3. The motor bearings are lubricated internally. No maintenance is
required or possible on the pump or the motor.

Table 2: Power Supply Wire (Cable) Length in Feet
1 Phase, 2 Wire Cable, 60 Hz (Copper Wire Size - Service to motor)
Hazardous voltage. Can shock, burn,
or kill. To reduce the risk of electrical
shock during pump operation, ground and bond the pump and
motor as follows:
A. To reduce risk of electrical shock from metal parts of the assembly
other than the pump, bond together all metal parts accessible at the
tank top (including metal discharge pipe, metal tank top, and the
like). Use a metal bonding conductor at least as large as the power
cable conductors running down the well to the pump's motor.
B. Clamp or weld (or both if necessary) this bonding conductor to the
grounding means provided with the pump, which will be the equip
ment-grounding terminal, the grounding conductor on the pump
housing, or an equipment-grounding lead. The equipment-grounding
lead, when provided, will be the conductor having green insulation; it
may also have one or more yellow stripes.
C. Ground the pump, motor, and any metallic conduit that carries power
cable conductors. Ground these back to the service by connecting a
copper conductor from the pump, motor, and conduit to the ground-
ing screw provided within the supply-connection box wiring compart-
ment. This conductor must be at least as large as the circuit conduc-
tors supplying the pump.
Save these instructions.
NOTE:
Sizes given are for copper wire. For aluminum wire go two
sizes larger (i.e., if table lists #12 copper wire, use #10 aluminum
wire.)
