The heater will not heat faster if you turn the thermostat all the way up. The heater will
never run without water running through it from the pool/spa filter pump.  When the
heater is started the fan will run right away.  The compressor will start after a 5 to 7
minute delay. The heating light will come on only when the compressor is running.
The heater will produce condensation at a steady rate. The condensation exits the
heater from the bottom drains.  The more humidity the more condensation. The ther-
mostat is accurate within three degrees and may not always match exactly to the de-
gree numbers printed on the control panel as it is effected by the humidity and other
factors.  The heater is designed to shut off in defrost mode when the air temperature
drop below 45˚F to 50˚F.

Warranty Service

Before calling for warranty service you should check the following first:

1.

 Clean all filters and traps in the pool circulation system. Low water flow will cause

the unit to shut down or cycle.

2.

 Check and adjust all water flow valves and adjust to the proper positions to insure

proper water flow through the heater.

3.

 Check the water pump timer setting to insure there is enough time allotted for a

proper heating cycle.

4.

 Check all circuit breakers and disconnects.  Note: More than one disconnect may be

required to shut off or turn on power to the heater.

5.

 Confirm that all heater controls, thermostat, thermostat selector switch, reset tripper,

and optional auto heat switch (if so equipped), are in the correct position.

6.

  If any 3rd party control devices are installed on the pool/spa system make sure they

are functioning properly.  Factory service technicians will not diagnose 3rd party exter-
nal control devices.  All external controls are disconnected during warranty service
and the heater is diagnosed as manufactured then reconnected.

7.  The limited factory warranty does not cover damage or conditions caused
by but not limited to the following:

Improper installation.
Improper use.
Inadequate run time on the water pump timer.
Improper water flow to the heater.
Conditions caused or associated with 3rd party external controls.
Chemical damage or improper water balance.
Sprinkler damage.
Roof run off damage.
Freeze damage or operation damage during freezing conditions.
Salt and/or sand/debris damage.
Lack of maintenance and/or cleaning.
Unauthorized servicing of the heater during the warranty period.
Normal rusting and oxidation of metal components.
Non warranty service calls such as inspections, maintenance, or problems unrelated to
the heater as it was manufactured are not covered under the warranty.

8.

  You can contact the factory @ 888-297-3826 to be pre-qualified and scheduled

with a factory authorized service center in your area. Have your model number, serial
number and installation date ready.
