TROUBLESHOOTING
POSSIBLE CAUSES
WATER DRIPPING INSIDE
• Wall sleeve is not installed level
• Clogged drain
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
SOLUTIONS
• Wall sleeve must be installed with a 1/4 bubble pitch
toward the outside for proper drainage of condensation.
Check that installation is level and make any necessary
adjustments
.
• The condensate drain may be partially or fully plugged.
• When outdoor temperature 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 start up delay
of 3 minutes and a minimum compressor 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
unit in.
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.
