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
“DEF”
.
NOTE: IT IS NORMAL FOR WATER TO DRIP FROM THE DRAINHOLES AT THE BASE OF THE
HEATER. THE UNIT PRODUCES CONDENSATION WHEN IT OPERATES.
