7. Use a at blade screwdriver (3/16 in tip width) to hold
the motor shaft. The motor shaft has a slot on the end
which is accessible through the center of the fan. Note:
Sometimes the impeller becomes tight on the shaft
after years of service. It may be necessary to hold the

Shaft Seal Replacement
The Shaft Seal consists primarily of two parts, a rotating
ceramic seal housed in the impeller and a stationary
spring seal in the sealplate. 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.

SERVICING
Always disconnect power to the IntelliPro
®
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.
