2. TO CLEAN THE BASKET – (pump must be off)
a. Follow the instructions above to prime the pump.
b. After removing the lid, remove the basket and empty the debris.
c. Replace the basket and proceed to fill the pot with water.
d. It is important to visually inspect the basket, through the see through lid, at least once
a week. A dirty basket will reduce the efficiency of your system, and can put an
abnormal load on the pump, which could result in costly repair bills.
3. SHAFT SEAL – (rotary seal). The shaft seal consists of two (2) parts:
a. Rotating spring loaded seal, press fitted into the impeller.
b. A stationary ceramic seal, press fitted into the rear of the volute.
4. THE ELECTRIC MOTOR.
a. The electric motor should be protected from foreign matter, water splashing, hosing,
and the weather. Enclosures should be well ventilated to prevent overheating. If a
motor becomes wet, permit it to dry before running it. If a motor has been damaged
by water or dirt, the warranty is void.
b. The motors used on these pumps are 48 frame through bolt motors. The through bolts
are used to secure the volute to the motor. When replacing the motor, mark the end
bells and the motor shell to indicate alignment. Remove the four nuts from the
through bolts at the shaft end. Place the shaft through the back of the volute and
locate the bolts in line with the brass inserts located in the four (4) legs at the rear of
the volute. Be sure the end bell and the shell marking line up. Securely fasten the
motor to the volute.
c. Protect the motor from heat. Provide ample ventilation.
CAUTION
The highly polished and lapped faces of the seal are easily damaged. Handle with care.
This centrifugal pump requires little or no service, however the shaft seal will wear with normal use over
the years and will require periodic replacement.
CAUTION
DO NOT RUN PUMP DRY. If the pump is run dry, the mechanical seal will be damaged and external
leakage will occur. When the seal is damaged, the seal must be replaced.
CAUTION
Always maintain proper water level in the pool. Water level must be half way up the skimmer opening.
A low water level can cause the pump motor to run dry which will damage the mechanical seal and
cause external leakage.
