Inspection and Service
WARNING
Improper installation or maintenance can cause nausea or asphyxia-
tion from carbon monoxide in fl ue gases which could result in severe
injury, or death.
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 efficiently through the years. Zodiac
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 qualified service technician.
WARNING
For your safety, when starting the heater, keep your head and face
away from the exhaust grill opening and blower inlet grill to prevent
any risk of personal injury. Make sure all doors/panels are securely
in place and stand back from the heater.
9.5.1
Guidelines for Homeowner Inspection:
WARNING
Do not store or use gasoline or other fl 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 qualifi ed service technician to inspect the heater and replace
any part of the control system and any gas control which has been
under water.
•
Keep 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, turn off the
filter pump and replace the pressure relief valve.
• Once a year check that water is running freely through
the pressure relief valve. To check, turn on the filter
pump and lift the release lever on the top of the valve.
• Be sure combustion air and ventilation openings are
not blocked.
9.5.2
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 Zodiac pool equipment.
• Check for loose or broken wires and terminal
connections.
•
Check the water pressure switch by turning the filter
pump off and on several times. The burner should go
off immediately after the pump stops. The fan run for
45 seconds after the burner shuts down.
CAUTION
If the heater is wired serially to or on the same relay as the fi 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.
•
Inspection the thermal regulator valve (TRV).
•
Inspect the electrical controls, specifically:
a. High limit switches.
b. Water pressure switch.
c. Automatic gas valve.
d. Power interface/Temperature control.
e. Flue temperature sensor.
f. Control circuit fuse.
g. Ignition 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.
•
If the heater is equipped with a pressure relief valve,
clean any accumulated corrosion and make sure that
water runs freely when lever is lifted.
• Inspect the outside of the combustion chamber and
blower for corrosion and indication of improper
operation.
•
Inspect electrical controls for deterioration. Repair
and replace as necessary.
•
Visually check the main burner flame. Remove the top
of the heater to inspect the sight glass. See
