®
Verify that skimmer baskets, pump basket and other screens are clean. Clean as
necessary.
Check filter and clean as necessary.
Check valve positions. Adjust as necessary.
NOTE Multiple pieces of equipment operating at one time (for example, waterfalls, spa
jets, and surface returns) will affect the proper operation of the cleaning system.
Check the cleaning system manual to ensure that the system is adjusted according to the
manufacturer's recommendations.
Air is in the system. Check the pool or spa water level to ensure that it is at the proper level
and air is not being drawn into the suction piping. If the water is at the normal level, turn off
the pump. Turn the lid's locking ring counter-clockwise until 'START' aligns with the ports.
Remove the lid and check for debris around the lid seal seat OR improper installation of
the lid seal, as either condition will allow air to leak into the system. Clean the lid seal and
replace it on the lid. Replace the lid on the pump housing. Align 'START' with the ports and
turn the locking ring clockwise until 'LOCKED' aligns with the ports. Hand-tighten the lid to
make an air-tight seal. Do not use any tools to tighten the lid. Turn the pump back on.
Check the suction side piping union. While the pump is running, try to tighten the union. If
this does not stop the air leak, turn off the pump. Loosen both unions and slide the pump
out of the way. Remove, clean, and inspect the union o-rings for excessive wear. Replace
the o-ring if it is cracked, brittle, or badly flattened.
Reposition the pump next to the piping and secure the union nuts to the pump.
It is possible that debris is caught in the pump impeller. The pump impeller moves the
water, and the vanes in the impeller can become blocked with debris. See Section
6.2, Service Technician Maintenance, 6.2.1, Blocked Impeller, in this manual for more
information.
The pump impeller and diffuser are showing signs of normal wear. Have a qualified service
technician check the impeller and diffuser and replace as necessary.
If the pump is part of a relatively new installation, it could be an electrical problem. Contact
a qualified service technician. Have the technician check for loose electrical connections
and check the voltage at the pump motor while it is in operation. The voltage must be within
10% of the motor's data plate rating. If the voltage is not within 10%, contact a qualified
electrician and/or the local power service provider.
Pump seal is leaking air. Have a qualified service technician replace the seal.
This is caused by a damaged or failed mechanical seal. Replace the seal. See Section 6.2,
Service Technician Maintenance, 6.2.3, Mechanical Seal Replacement, in this manual.
Make sure that there is adequate room around the motor to circulate air and keep the
motor cool. Have a qualified electrician check for loose connections and check the voltage
at the pump motor while it is in operation. The voltage must be within 10% of the motor's
data plate rating. If the voltage is not within 10%, contact a qualified electrician and/or the
local power service provider.
