Specifications

Shaft Rotation - To check for a free turning pump turn the power off and rotate the motor shaft. This can be
done by removing the motor end cap located on the back of the motor. Rotate the motor shaft in a clockwise
direction. Do not start the pump if the motor shaft cannot be turned.
Shaft Rotation (3 Phase Motors) - After the proceeding instructions have been completed, turn the motor on
for 1 second. If the connection is correct, the motor shaft will rotate clockwise when viewed from the end oppo-
site the motor shaft extension. If the rotation is not correct, reverse any two leads to the starter. The rotation will
now be correct.
Valves - The suction inlet valve should be fully open and the discharge valve should be partially open. This will
allow the pump to develop back pressure when it is started.
Priming - The pump will automatically fill with water when the pump is connected to a city main, hydrant or
water tank. To relieve the air trapped inside the pump, allow the water supply to run a minimum of 1 minute
before starting the pump. Then, turn the motor on and off several times to free the air trapped inside the pump.
Repeat this priming sequence several times to be sure all the air has been removed from the pump. Start and
run the pump for 1 minute. The pump should be pumping water and rapidly build pressure. If not repeat the
priming procedure.
Start-Up Procedures
Warning: The pressure gauge installed in the inlet line should never read less than 2 PSI. This insures
that an ample supply of water is flowing into the pump.
- 11 -
Starting - When the pump is up to operating speed, open the discharge valve to obtain the desired capacity or
pressure. Do not allow the pump to run with the discharge valve closed because the liquid in the pump can get
extremely hot.
Warning: The discharge pressure should never be allowed to exceed 85 PSI, otherwise, leakage between
the motor bracket and pump casing will occur.
Final Inspection - Once the proceeding instructions have been completed the pump can be started. During the
first few hours of operation, inspect the pump, piping and auxiliary equipment used in conjunction with the pump.
Check for leaks, vibration or noises.
If a problem arises, consult a Webtrol representative or call Webtrol at [phone] for assistance.
Maintenance
The pump does not require special maintenance. If the pump is not going to be used for a long period, the pump
should be drained of water and flushed with clean water. Where the pump is exposed to freezing temperatures,
it should always be left drained when not in use.
