motor Will NOT Start – Check For:
Make sure the terminal board connections agree with the wiring diagram on motor data plate label. Be sure
motor is wired for available field supply voltage (see pump operating label).
1. Improper or loose wiring connections; open switches or relays; tripped circuit breakers, or blown fuses.
Solution
: Check all connections, circuit breakers, and fuses. Reset tripped breakers or replace blown fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction.
Solution
: Refer to
Steps 3 & 4 of “Shaft Seal Change Instructions” in this manual.
3. If you have a timer, be certain it is working properly. Bypass it if necessary.
motor Shuts OFF – Check For:
1. Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
Solution
: Contact qualified professional to check that the wiring gauge is heavy enough.
NOTE
: Your Advantage pump motor is equipped with an “automatic thermal overload protector.” The motor
will automatically shut off if power supply drops before heat damage can build up causing windings to burn
out. The “thermal overload protector” will allow the motor to automatically restart once the motor has cooled.
It will continue to cut On/Off until the problem is corrected. Be sure to correct cause of overheating.
motor hums, But Does NOT Start – Check For:
1. Impeller jammed with debris.
Solution
: Have a qualified repair professional open the pump and remove
the debris.
Low Flow – Generally, Check For:
1. Clogged or restricted strainer or suction line.
Solution
: Contact a qualified repair professional.
2. Undersized pool piping.
Solution
: Correct piping size.
3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading).
Solution
: Sand
filters – backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s
instructions; Cartridge filters – clean or replace cartridge.
4. Air leak in suction (bubbles issuing from return fittings).
Solution
: Re-tighten suction and discharge
connections using Teflon tape. Inspect other plumbing connections and tighten as required.
5. Plugged, restricted, or damaged impeller.
Solution
: Replace including new seal assembly.
Noisy pump – Check For:
1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint,
low water level in pool, and unrestricted discharge return lines.
Solution
: Correct suction condition or throttle
return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a
smaller eyeball fitting.
2. Vibration due to improper mounting, etc.
Solution
: Mount the pump on a level surface and secure the pump
to the equipment pad.
3. Foreign matter in pump housing. Loose stones/debris hitting impeller could be cause.
Solution
: Clean the
pump housing.
4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal
damage which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to
whine.
Solution
: All seal leaks should be replaced at once.
