, Vent door left open
* Unit may be in a protection or diagnostic failure
mode. Check section on Intelligent Self-checking
Control.

time delay (approx. 3 minutes) on starting the
compressor after a power outage (or restarting
after it has been turned off), to prevent tripping of
the compressor overload.

. Wall sleeve is not installed level
iCE OR FROST FORMS ON INDOOR COIL
. Low outdoor temperature
. Dirty filters
COMPRESSOR PROTECTION
. Power may have cycled, so compressor is in a
restart protection.
WALL THERMOSTAT PROBLEM
NOTES:
. Check that plug is plugged securely in wall receptacle.
Note :Plug has a test/reset button on it. Make sure that the plug
has not tripped.
* Replace the fuse. See Note 1.
* Reset circuit breaker. See Note 1.
, Turn unit on (bottom right button on keypad).
Note: If the unit turns on, the LED will be green. If the unit is off,
the LED will be red. If there is no LED on, there is a problem
with power or damage to the control.
. Make sure that curtains, blinds or furniture are not restricting or
blocking unit airflow.
, Reset to a lower or higher temperature setting.
* Remove and clean filters.
, Allow sufficient amount of time for unit to heat or cool the room.
Start heating or cooling early before outdoor temperature, cooking
heat or gatherings of people make room uncomfortable.
* Close vent door.
. Check dipswitch settings for desired comfort.
Wait approximately 3 minutes for compressor to start
. The unit may be in a diagnostic condition. Check Intelligent Self-
checking Control section to determine if unit has had a failure.
* The unit may be set for °C (instead of °F), see the keypad
configuration section
. Clicking, gurgling and whooshing noises are normal during
operation of unit.
* If a drain kit has not been installed, condensation runoff during
very hot and humid weather is normal. See Note 2. If a drain kit has
been installed and is connected to a drain system, check gaskets
and fittings around drain for leaks and plugs.
. Wall sleeve must be installed level for proper drainage of
condensation. Check that installation is level and make any
necessary adjustments.
. When outdoor temperature o is approximately 55 F (12.8°C) or
below, frost may form on the indoor coil when unit is in Cooling
mode. Switch unit to FAN operation until ice or frost melts.
. Remove and clean filters.
. Random Compressor restart = Whenever the unit is plugged in,
or power has been restarted, a random compressor restart will
occur. After a power outage, the compressor will restart after
approximately 3 minutes.
* Compressor Protection - To prevent short cycling of the
compressor, there is a random startup delay of 3 minutes and a
minimum co m pressor run time of 3 minutes.
* Verify wiring is correct between thermostat and unit.
* Dip Switch settings are only read during power up. Unplug unit
and verify Dip Switch Settings, then plug in unit.
1=If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician=
2= If unit is installed where condensation drainage could drip in an undesirable location, an accessory drain kit should be insta!led and connected to drain
