Troubleshooting
Measure the temperature of
suction air and supply air.
Temperature difference =
Suction air temp. – Supply air
temp.
Possible causes as follows
∗
Incorrect selection of model
∗
Affection of direct sun
∗
Clogged air filter
∗
Soiled heat exchanger
∗
Malfunction of fan motor
(Refer error code “A6”.)
Possible causes as follows
∗
Refrigerant overcharge
∗
Air in refrigerant system
∗
Soiled heat exchanger
∗
Short circuit of supply air
∗
Disturbing item in air flow
∗
Malfunction of fan motor of
outdoor unit
(Refer error code “E7”, “H7”.)
Possible causes as follows
∗
Insufficient compression of
compressor
∗
Insufficient circulation of
refrigerant
∗
Faulty expansion valve
Gas shortage possibly
generates trouble.
Normal.
Additional unit installation
should be considered
After vacuum drying, charge
correct amount of refrigerant.

Temperature
difference for cooling
should be between 8
and 18˚C.
Does
any frost generate
around inlet port of
indoor unit heat exchanger
or outlet port of
expansion
valve?
Is the
operation current
less than specified
level?
Does indoor
unit air flow
rate down?
Is the level
of high pressure higher
than normal
level?
Does the
heat load increase after
installation of the
unit?
