• The adequate air flow direction may differ depending on the
conditions (air conditioner's installation position, room structure or
furniture layout, etc.). If the cooling or the heating is not well, adjust
the air flow direction.
• The position of the louvers may not coincide with the louver position
indicator on LCD during the auto swing operation. When fixing the
louver angle, set it according to the louver position on LCD.
• Even if " " or " " is pressed to stop the auto swing, the louver may
not be stopped soon.
• If the cooling operation is performed under the condition with over
80% humidity, dew condensation may occur at the air panel or the
louver.

• Check to ensure that the electrical resistance is more than 1
megohm, by measuring the resistance between ground and the
terminal of the electrical parts. If not, do not operate the system
until the electrical leakage is found and repaired.
• Do not touch any of the parts at the discharge gas side by hand
while the system is running, since the compressor chamber and
the pipes at the discharge side are heated higher than 90ºC.
19.1 BEFORE TEST RUN
Recheck that there is not any problems to the installation, and
do not perform the test run until all the following checking points
have been cleared.
1 Check to ensure that the refrigerant piping and the transition
wiring are connected to the same refrigerant cycle system.
If not, it will cause an abnormal operation and breakage of
instruments.
2 Do not apply the high voltage to the terminals for the

• Check to ensure that the stop valves of the outdoor unit are fully
opened, and then start the system.
• Check to ensure that the switch on the main power source has
been ON for more than 12 hours, to warm the compressor oil by the
crankcase heater.
3 Check to ensure that each wire is correctly connected at
the phase of power source. If incorrectly connected, the unit
will not operate and the remote control switch will indicate
the alarm code "05". In this case, check the phase of the
primary power source according to the attached attention
label on the rear side of the service cover. Then, perform
the reconnection work correctly with turning OFF the power
supply.
4 Check to ensure that the main power source has been
turned ON for more than 12 hours, to warm the compressor
oil by the crankcase heater.
