• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air condi-
tioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

line connection
AHU sensor connection
• 2 outdoor units can be connected to
communication PCB 1EA, so be careful
not to have mixed connection of the pipe
temperature sensor and communication
line that are connected to 1 outdoor unit.
• You must install temperature/humidity
sensor to SA duct and RA duct that com-
ply with the specification.
(Specification: -40 °C~70 °C,
RH 0~95 % / AC 24 V / DC 0~10 V)
•
If only temperature sensor is installed to SA/
RA duct, you do not need to set Dip switch.
•
According to the installation site, set the
Dip switch according to the setting method.
• Be careful of the Dip switch setting accord-
ing to whether outdoor unit is connected.
• During the connection of outdoor unit,
make sure to set all rotary switches to be
different.
• After completing CONTROL KIT installa-
tion, make sure to set outdoor unit
address.
