Tips
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.
POSSIBLE CAUSES SOLUTONS
WATER DRIPPING INSIDE
• W
all 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.
• Dirty filters.
• 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.
COMPRESSOR PROTECTION
• Power may have cycled, so
compressor is in a restart
protection.
• 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.
ELECTRIC HEATING FAILURE
• Clean the evaporator twice yearly by qualified
personnel.
