MAINTENANCE
WARNING: DISCONNECT ELECTRICAL POWER TO UNIT BEFORE STARTING ANY
MAINTENANCE TO PREVENT SERIOUS INJURY FROM SHOCK.
Protecting your Heater
•
Keep your pool filter system clean and free of restrictions to ensure proper water flow.
•
Check water chemistry regularly. Misuse of chemicals will cause permanent damage to
your heater and other pool equipment. Manufacturers can void warranties for damage as a
result of poor water quality.
•
Free airflow is essential. Keep the evaporator coil clean and free of weeds, leaves, glass
clippings, dirt and other debris that will decrease the airflow. Keep fences and shrubs away
from air inlets (sides and back of heater).
•
Frequent rinsing of the evaporator with fresh water will remove build up from its surface.
Always spray the coil gently with a regular garden hose being careful not to bend aluminum
fins.
•
Regular cleaning of the cabinet will improve its appearance and extend the life of the
finish.
Winterizing
When the heater is exposed to freezing temperatures, it is essential that all water within the
unit be properly drained. When water freezes, it expands, damaging piping.
•
Turn thermostat settings to OFF. Turn filter pump to OFF.
•
Turn power to unit OFF (i.e. pull disconnect or turn circuit breaker OFF).
•
Disconnect water inlet and outlet unions at the back of the unit. Be careful not to lose
rubber o-rings.
•
Flush the heater piping out with fresh water to remove any residual chemicals.
•
Use low-pressure air or vacuum to remove water that has accumulated inside the piping of
the heater.
TROUBLESHOOTING CHECKLIST
•
Check to see that the electrical power is on. Reset breakers, or replace fuses if necessary.
•
Check to be sure the electric control panel is set properly. The desired temperature must be
set above
the actual pool or spa temperature for the heater to run.
•
Check to make sure the evaporator coil has enough clearance and that there are no
restrictions to its airflow.
•
Certain ambient air conditions may cause the heater to go into defrost mode, displayed on
the control panel as
“AIR DEFROSTING”
or
“REVERSE CYCLE.”
