• 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.

Control Kit Installation

Connect the pipe tempera-

ture sensor

Connection the outdoor unit

communication line

Connect the AHU sensor

Since up to 3 outdoor units can be connect-

ed to 1 communication module, do not mix

the communication line with the pipe tem-

perature sensors that are connected to

each of the outdoor units.

Make sure to install the temperature/

humidity sensors that meets the specifica-

tions to the SA (supply)/RA (ventilation).

(Spec: -40 °C~70 °C, RH 0~95 %,

AC 24 V / DC 0~10 V)

The Control Kit and Driver Kit must be con-

nected with a communication line in order to

start the SA (supply)/RA(ventilation).

(For more details, please refer to Fan Driver

Connection in page 41.)

h Refer to Rated Fan Output Port in the

Wiring Diagram when using a rated fan

motor.

When applying an optional sensor for certain

installation sites, configure the settings in

HMI in accordance with the site conditions.

(For more details on settings, refer to About

HMI.)

When using Capacity Control: Make sure to

install 'Central Control PI485' on the out-

door unit. After installing the Control Kit, set

the address for outdoor units, starting from

No. 1. Incorrect outdoor unit address can

cause the product to malfunction.

After all the installation steps have been

completed, set the values necessary for

running the product by setting the HMI sys-

tem. (For more information, refer to HIM

System Settings.)

space between the brackets for fasten-

ing the electric wires at the bottom of

the outdoor unit box to block the wire

hole. (Rats and other small animals can

enter the box and damage the wires.)

• After installing the product, check the

security status of the AHU and outdoor

unit connection. Failure to ensure the

security can cause information leak.

• Make sure to use an outdoor unit box to

protect the Control Kit when installing

the AHU outdoors.
