UNIT NOT COOLING/HEATING ROOM

 

• Unit air discharge section is blocked

• Make sure that curtains, blinds or furniture are not restricting or

 

blocking unit airflow.

• Temperature setting is not high or low enough

• Reset to a lower or higher temperature setting.

•Unit air filters are dirty

•Room is excessively hot or cold when unit is started • 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.

•Vent door left open• Close vent door.• Remove and clean filters.

UNIT MAKING NOISES

• Clicking, gurgling and whooshing noises are normal during operation of

 

unit.

WATER DRIPPING OUTSIDE

• If a drain kit has not been installed, condensation run-off 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.

WATER DRIPPING INSIDE

 

• Wall sleeve is not installed level

• Wall sleeve must be installed level for proper drainage of condensation.

 

Check that installation is level and make any necessary adjustments.

ICE OR FROST FORMS ON INDOOR COIL

 

• Low outdoor temperature

• 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.

• Dirty filters

• Remove and clean filters.

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.
