FloPro ssPump installation & Operation Manual
The pump is
leaking water
between the motor
and pump body.
This is caused by a damaged or failed mechanical seal. Replace
the seal. See
Section 6.2, Service Technician Maintenance, 6.2.4,
Mechanical Seal Replacement.
The pump gets
hot and shuts off
periodically.
Ensure that there is adequate ventilation and 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.
6.2 Service Technician Maintenance
This pump must be serviced by a professional service technician, qualified
in pool/spa installation. The following procedures must be followed exactly.
Improper installation and/or operation can create dangerous electrical hazards,
which can cause high voltages to run through the electrical system. This can
cause property damage, serious injury, and/or death. Improper installation
and/or operation will void the warranty.
6.2.1 Blocked Impeller
Before servicing the pump, turn off the pump and switch off the circuit breaker
to the pump motor. Severe personal injury, death, or property damage may
occur if the pump starts while your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker to the pump motor.
2. Remove the lid and basket.
3. Look inside the pump for any debris. Remove any debris found inside.
4. Replace the basket and lid.
5. Switch on the circuit breaker to the pump motor.
6. Turn on the pump, and see if the problem is solved.
7. If the impeller is still blocked with debris and it is not possible to remove the debris
using Steps 2 through 4, the pump will need to be disassembled in order to access
the inlet and outlet of the impeller.
6.2.2 Impeller Removal
Before servicing the pump, turn off the pump and switch off the circuit breaker
to the pump motor. Severe personal injury, death, or property damage may
occur if the pump starts while your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker to the pump motor. If you are not
replacing the motor, do not disconnect the electrical wiring.
NOTE: If you are replacing the motor, Zodiac strongly recommends that a qualified service
technician or electrician properly disconnect the electrical wiring at the pump motor.
6.1 Troubleshooting
SYMPTOM
POSSIBLE PROBLEM/SOLUTION
The cleaning/
circulating system
is not operating
correctly.
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) may affect the cleaning system and
prevent it from working properly. Check the cleaning system
manual to ensure that the system is adjusted according to the
manufacturer's recommendations.
Bubbles/air
present in the
pump basket.
(Suction Leak)
Air in system. Check the pool or spa water level to ensure that it is
at the proper level and that 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. Carefully remove the lid and check for debris around
the lid o-ring seat, as debris will cause air to leak into the system.
Clean the lid o-ring and place on the lid. Replace the lid with locking
ring on the pump housing. Align ‘START’ with the ports and turn
the lid’s 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.
Air leaks are still
present.
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 re-install both union o-rings. Reposition
the pump next to the piping and secure the union nuts to the pump.
With clean union o-rings, hand-tightening of the unions should
create a seal. If the unions still do not seal, gently tighten with a
large pair of tongue-and-groove pliers.
Do not over-tighten.
There is no air in
the system, but
the pressure is still
low.
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,
for more information.
There is no debris
blocking the
impeller
and
the
pressure is still
low.
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. The pump seal might be leaking air. Have
a qualified service technician replace the seal. 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.
