Trouble Shooting - continued
PROBLEM
5. Motor runs hot.
6. Noisy operation of
pump.
7. Motor overload
protection "kicks out".
8. The LED light is not
working?
9. The volume control
knob keeps spinning?
10. My ON/OFF air
button is not working
properly?
11. The system will not
turn OFF?
POSSIBLE CAUSES
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 o if there is an overload or high
temperature problem. Excessive heat can be caused by:
a. Low voltage.
b. Installed in direct sun.
c. Poor ventilation.
a. Air leak in suction line.
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.
a. Moisture in air tubing or bad air
button.
b. Control Box.
a. Broken Spindle.
a. Control Box.
b. Air tubing.
a. Control Box Components.
SOLUTION
Increase size of electrical wire. Be sure motor is
operating on correct voltage.
Shield motor from sun's rays.
DO NOT block motor ventilation openings.
Repair leak. Check suction pipe, red filler plug, and
o-ring (See Problem 1).
Remove blockage or increase suction pipe size. Are all
suction valves fully open?
Disassemble pump and remove foreign matter from
impeller.
Improve suction conditions. (Reduce suction line
length, reduce number of fittings, increase pipe size.)
Check wiring diagram on motor.
Check with volt meter. Increase size of supply wire.
Report 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.
Remove air tubing from air switch at control box. Con-
nect a short piece of air tubing to the L.E.D. air switch.
Blow into tube and check if L.E.D. turns on/o .
Contact certified electrician to diagnose control box
components.
Contact the factory 800-223-8538
Check GFCI. If green LED does not stay ON, contact a
certified electrician to diagnose control box compo-
nents.
Check air tubing connection on the control box. Check
that the tubing is not bent or pinched. Tubing may
need to be replaced.
Press TEST button on the control box GFCI to turn o
system. Contact a certified electrician to diagnose con-
trol box components.
