• 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 equipment.

• Keep doors or windows closed tightly while you are operating the equipment.

• 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.

• 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.

Cautions in installation structuring

• A facility company is responsible for MCC construction work, and a separate discussion should

be made before an installation.

• A temperature sensor or a temperature/humidity sensor should be installed to at SA (supply air)

INSTALLATION PROCESS DIAGRAM

• Please, install a product in accordance with the process below.

Since maximum 3 outdoor units can be connect-

ed to one communication module, be careful

not to mix piping temperature sensor connected

to each outdoor unit and communication line

connection.

Be sure to install the temperature/humidity sen-

sors which match the specifications to SA (air

supply)/RA (return air) ducts. (specification: -

40 °C~70 °C, RH 0~95 %, AC 24 V/DC 0~10 V)

It needs to connect control kit and drive kit with

a communication line to operate SA (air sup-

ply)/RA (return air fan motor.

- When a constant speed fan motor is used,

refer to the constant speed fan output port of a

wiring diagram.

When an option sensor is applied, set up HMI in

a way to meet the field condition by an installa-

tion field. (Refer to HMI explanation for set up

details.)

When using capacity control:

Be sure to install “central control PI485’ at the

outdoor unit. After completing a Control Kit

installation, set up outdoor unit addresses serial-

ly starting from 1. Erroneous set up in outdoor

unit addresses could disrupt normal operation.

After all installations are completed, set up the

values required for product operation should be

made through HMI system set up. (Refer to

HMI system set up for detailed information.)

CAUTION

• Do not set up while a product is in operation since there is a risk of electric shock, etc.

poses)

ELECTRICITY WIRING

ENGLISH

ELECTRICITY WIRING

Cautions

• Regard to the regulations about electric facility and electric lines, follow the policy of technical

standard governmental organizations and directions of an electric companies.

• Separate the communication lines with outdoor units and sensor signal lines from power lines

so that they are not affected by the electric noise caused by communication lines and power

lines (Don’t let them pass through the same electric lines).

• Be sure to do the grounding for an inverter drive kit.

• Never connect the main line with communication lines and the terminal sockets of sensor sig-

nal lines. If connected, electric components and sensors are damaged.

• Do not use 2-line shield as a communication line.

If one shield cable is connected to the other system, receiving and sending communication will

be deteriorated and an abnormal operation will occur.

WARNING

• Following the relevant regulations and current installation manual, use an electric techni-

cian for the electric works which require special circuits. When there is an insufficient elec-

tric supply circuit capacity or a defect, an electric shock or fire could occur.

WARNING

• In accordance with the relevant regulations and current installation manual, let a qualified

electricity engineer do the electric works which uses special circuits. When there is an

insufficient electric supply circuit capacity or a defect, an electric shock or fire could occur.

WARNING

• Be sure to ground an inverter drive kit. Do not connect the ground lines with gas pipes,

water pipes, a lightning rod, or telephone line ground lines. Incomplete ground causes an

electric shock.

WARNING

• When you connect electric lines, do them after completing ring socket works. It causes

fire and damages in electric components.
