SECTION 3 SERVICING INFORMATION
When calling the manufacturer regarding a question or
problem with your pump, please have the serial number
available. The serial number is located on the pump either
on the flange or motor labels.
POSSIBLE CAUSES
a. Dirty filter.
b. No skimmer basket.
c. Closed valves or blocked lines.
d. Suction air leak.
a. Bad bearings.
These motors will run hot to the touch, however, this is normal. They are designed that
way. Thermal overload protector will function to turn them off if there is an overload or high
temperature problem. Excessive heat can be cause by:
a. Low voltage.
b. Installed in direct sun.
c. Poor ventilation.
a. Air leak in suction line. Bubbles
in water returning to pool at inlet.
b. Restricted suction line due
to blockage or under size pipe.
Indicated by high vacuum reading
at pump suction.
c. Foreign matter (gravel, metal,
etc.) in pump impeller.
d. Cavitation.
a. Motor is not connected properly.
b. Low voltage due to under size
wire or low incoming voltage.
c. Wrong size heaters in protective
device.
d. Overload due to binding in pump
or wrong size impeller.
Back wash filter when filter pressure is high, or clean
cartridges.
Clean skimmer and pump strainer basket.
See problem 1.
See problem 1.
Noise when shaft is turned up by hand. Motor is hot in
bearing area when running. Replace bearing.
Increase size of electrical wire. Be sure motor is
operating on correct voltage.
Shield motor from sun's rays.
Do not tighten cover or enclosure motor.
Repair leak. Check suction pipe, see-through lid in
place? O-ring clean?
Remove blockage or increase suction pipe size. Make
sure strainer tank is clean. Are all suction valves fully
open?
Disassemble pump and remove foreign matter from
impeller.
Improve suction conditions. (Reduce suction life,
reduce number of fittings, increase pipe size.) Increase
discharge pressure and reduce flow by throttling
discharge valve.
Check wiring diagram on motor.
Check with volt meter. Increase size of supply wire.
Reports low supply voltage to power company. Voltage
at motor must be within 10% of motor nameplate
voltage.
Heaters should be one size larger than full load amps
shown on motor nameplate.
Indicated by high amperage readings on motor, binding
shaft. Disassemble unit and correct.
Replacement parts may be available from your installer.
