DISPLAY HAS STRANGE
NUMBERS/CHARACTERS ON IT
UNIT MAKING NOISES
WATER DRIPPING OUTSIDE
WATER DRIPPING INSIDE
• 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.
NOTES:
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 installed and connected to drain
system.
SOLUTIONS
• 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.
S Make sure that curtains, blinds or furniture are not restricting or
blocking unit airflow.
S Reset to a lower or higher temperature setting.
S Remove and clean filters.
S 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.
S Close vent door.
S 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 is approximately 55_F 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 compressor run time of 3 minutes.
