4. Start the pump. Unit should pump water within

30 seconds. If not, stop pump and repeat steps
1 through 3. On first use of pump, it may be
necessary to re-prime the unit three or four
times before all the air is out of suction pipe.

IMPORTANT: If the pump fails to build prime,

there may be an air pocket in the pump case.
To break up trapped air, connect 1/4” plastic
tube, using a brass ferrule connector, to the
priming air vent port. (Not supplied.)

IMPORTANT: With the pump case completely

full of water and the priming tee plug in place,
submerge tubing into a bucket of water. Turn
on power to motor. When pump builds up
pressure, turn off power, remove tubing and
ferrule connector and replace 1/4” plug (See
Figure 6.)

5. Once the pump is primed, tighten the priming

plug. Remember to close the faucets.

Once the preceding instructions have been
completed, the pump can be started.

1. During the first few hours of operation, inspect

the pump, piping and any auxiliary equipment
used in connection with the unit.

2. Check for leaks, excessive vibration or unusual

noise.

IMPORTANT: Flow into well must at least equal
flow out through pump! See Performance Chart B.

Never examine, make wiring

changes or touch the motor before disconnecting the
main electrical supply switch. The thermal device may
have opened the electrical circuit.

Motor Protection
All single phase motors have built-in thermal
protection for all voltages. The overload protects
the motor against burnout due to low voltage, high
voltage and other causes. The device is automatic
and resets itself once the temperature has dropped
to a safe point. Frequent tripping of the device
indicates trouble in the motor or power lines, and
immediate attention is needed.

Disconnect power supply and

de-pressurize system before servicing pump or
removing any component.

Lubrication
The motor has pre-lubricated bearings. No
lubrication is required.
