Installation Manual 9

ENGLISH

Before Installation

■ Don't install or operate the unit in rooms mentioned below.

Where mineral oil, like cutting oil is present.

Where the air contains high levels of salt such as air near the ocean.

Where sulphurous gas is present such as that in areas of hot spring.

In vehicles or vessels.

Where voltage fluctuates a lot such as that in factories.

Where high concentration of vapor spray are present.

Where machines generating electromagnetic waves are present.

Where acidic or alkaline vapor is present.

The option boxes must be installed with entrances downward.

CAUTION

■ Check the mentioned below, when you apply the AHU(Field supply).

If the AHU (Field supply) provided in the field is exclusively for heating, you must not

change the operating mode to cooling on the remote controller. If not, it can cause electric

shock, injury or death. If you want to operate in cooling mode, AHU (Field supply) must

comply with the following details.

(Following)

- The insulation level of AHU (Field supply) motor must be ‘F’ or above, and the protection

level must satisfy ‘IP 54’.

- AHU (Field supply) must have the drain pan installed.

Fan speed button on the wired remote controller(PQRCUSA0) is not operated.

For refrigerant piping of outdoor unit, refer to the installation manual supplied with the

outdoor unit.

For installation of the wired remote controller(PQRCUSA0), refer to the manual supplied

with the wired remote controller.

For connection of the Dry contact PCB(PQDSBNGCM0), refer to the manual supplied with

the Dry contact PCB(PQDSBNGCM0).

■ AHU Control Kit

Thermistor cable and remote controller wire should be located at least 50mm away from

power supply wires and from wires to the controller. Not following this guideline may result

in malfunction due to electrical noise.

Use only specified wires, and tightly connect wires to the terminals. Keep wiring in neat

order so that it does not obstruct other equipment. Incomplete connections could result in

overheating, and in worse case electric shock or fire.
