MAINTENANCE
Always disconnect power to the Variable Speed Pump at the circuit breaker and disconnect the
communication cable before servicing the pump. Failure to do so could result in death or serious
injury to service people, users or others due to electric shock. Read all servicing instructions before working on the
pump.
DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water
in the strainer pot. Pumps operated in these circumstances may experience a build up of vapor
pressure and may contain scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the
possibility of personal injury, make sure the suction and discharge valves are open and strainer pot temperature is cool
to touch, then open with extreme caution.
Be sure not to scratch or mar the polished shaft seal faces. Seal will leak if faces are damaged.
The polished and lapped faces of the seal could be damaged if not handled with care.
Electric Motor Care
Protect from heat
1. Shade the motor from the sun.
2. Any enclosure must be well ventilated to prevent
overheating.
3. Provide ample cross ventilation.
Protect against dirt
1. Protect from any foreign matter.
2. Do not store (or spill) chemicals on or near the
motor.
3. Avoid sweeping or stirring up dust near the motor
while it is operating.
4. If a motor has been damaged by dirt, it may void
the motor warranty.
5. Clean the lid and clamp, o-ring and sealing
surface of the pump pot.
Protect against moisture
1. Protect from splashing or sprayed water.
2. Protect from extreme weather such as flooding.
3. If motor internals have become wet, let them
dry before operating. Do not allow the pump to
operate if it has been flooded.
4. If motor has been damaged by water, it may void
the motor warranty.
Shaft Seal Replacement
The shaft seal consists primarily of two parts, a
rotating member and a ceramic seal.
The pump requires little or no service other than
reasonable care, however, a shaft seal may
occasionally become damaged and must be replaced.
Note: The polished and lapped faces of the seal could
be damaged if not handled with care.
