10.5 Inspection and Service
WARNING
Improper installation or maintenance can cause nausea or asphyxia-
tionfromcarbonmonoxideinuegaseswhichcouldresultinsevere
injury, or death.
WARNING
For your safety, when starting the heater, keep your head and face
away from any exhaust or inlet grill openings to prevent any risk of
personal injury. Make sure all doors/panels are securely in place and
stand back from the heater.
The heater is designed and constructed to provide
long performance life when installed and operated
properly under normal conditions. Periodic inspections,
especially at spring start-up, are important to keep
your heater running safely and efciently through the
years. Zodiac Pool Systems LLC recommends that
the homeowner inspect the heater on a regular basis
(especially after abnormal weather conditions), and
arrange to have a professional inspection at least once a
year by a qualied service technician.
10.5.1 Guidelines for Homeowner Inspection:
WARNING
Donotstoreorusegasolineorotherammablevapors,liquidsor
chemicals in the vicinity of this or any other appliance.
WARNING
Do not use this heater if any part has been under water. Immediately call
aqualiedservicetechniciantoinspecttheheaterandreplaceanypart
of the control system and any gas control which has been under water.
WARNING
To Reduce the Risk of Fire, install pool equipment in an area where
leaves or other debris will not collect on or around the equipment.
Keep surrounding area clear of all debris such as paper, leaves,
pine-needles and other combustible materials.
• Ensure the top of the heater, under the heater, and
surrounding area clear of all debris and combustible
materials such as paper, leaves, etc.
• If there is a pressure relief valve, check for corrosion
in and around the valve. If there is corrosion, contact a
pool professional for replacement of the
pressure relief valve.
• Once a year check that water is running freely through
the pressure relief valve. To check, turn on the lter
pump and lift the release lever on the top of the valve.
• Be sure combustion air and ventilation openings are
not blocked.
10.5.2 Guidelines for Professional Inspection:
The following inspections should be made once a year or
as needed. Routine inspections are a critical to the safety
and long life of your Jandy pool equipment.
• Check for loose or broken wires and
terminal connections.
• Check the water pressure switch by turning the lter
pump off and on several times. The burner should go
off immediately after the pump stops. The fan will
run for 45 seconds after the burner shuts down.
CAUTION
Iftheheateriswiredseriallytooronthesamerelayasthelter
pump, there is a chance that power will be disconnected to the
heater before the fan is able to fully purge the combustion chamber.
It is inadvisable to install the heater in a manner which would pre-
vent this combustion chamber purge from taking place.
• An ignition sequence should start shortly after the
pump is turned back on.
• Inspect the thermal regulator valve (TRV).
• Inspect the electrical controls, specically:
a High limit switches e Flue temperature sensor
b Water pressure switch f Control circuit fuse
c Automatic gas valve g Ignition control
d Power interface/
Temperature control
h Air pressure switch
• Inspect the inlet grill at the blower for blockage,
leakage, and corrosion.
• Inspect the combustion blower for damage.
• Conduct a normal operating cycle and observe that
the sequence proceeds as intended.
