PRECAUTIONS FOR SAFETY

CAUTION New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT

DESTROY OZONE LAYER.

The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main unit and installation tools are charged from those for the conventional refrigerant.

Accordingly the exclusive tools are required for the new refrigerant (R410A). For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does

not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it.

ENGLISH

CAUTION To Disconnect the Appliance from Main Power Supply.

This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

The installation fuse (25A D type

) must be used for the power supply line of this conditioner.

WARNINGS

• Ask an authorized dealer or qualified installation professional to install/maintain the air

• Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

• When the air conditioner is installed in a small room, provide appropriate measures to

ensure that the concentration of refrigerant leakage occur in the room does not exceed the critical level.

• Install the air conditioner securely in a location where the base can sustain the weight

adequately.

• Perform the specified installation work to guard against an earthquake.

If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

• After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might generate.

• Electrical work must be performed by a qualified electrician in accordance with the

Installation Manual. Make sure the air conditioner uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

• Use the specified cables for wiring connect the terminals securely fix. To prevent external

forces applied to the terminals from affecting the terminals.

• Conform to the regulations of the local electric company when wiring the power supply.

Inappropriate grounding may cause electric shock.

• Do not install the air conditioner in a location subject to a risk of exposure to a combustible

gas.

If a combustible gas leaks, and stays around the unit, a fire may occur.

SELECTION OF INSTALLATION PLACE

WARNING

• Install the air conditioner at enough strong place to withstand the weight of the unit.

If the strength is not enough, the unit may fall down resulting in injury.

• Install the air conditioner at a height 2.5m or more from the floor.

SELECTION OF INSTALLATION PLACE

Selection of installation place

In case of continued operation of the indoor unit under high-humidity conditions as described below, dew may condense and water may drop.

Especially, high-humidity atmosphere (dew point temperature : 23°C or more) may generate dew inside the ceiling.

1. Unit is installed inside the ceiling with slated roof.

2. Unit is installed at a location using inside of the ceiling

as fresh air take-in path.

3. Kitchen

If installing a unit at such place, put insulating material (glass wool, etc.) additionally on all the positions of the indoor unit which come to contact with high-humidity atmosphere.

Drain pan

• After the electric work has finished, pour water during COOL mode operation.

• If the electric work has not yet finished, pull out the float switch connector (CN34 : Red) from the electric parts box, and check draining by plugging the single phase 220/230/240V power to the terminal blocks 1 and 2. If doing so, the drain pump motor operates.

• Test water drain while checking the operation sound of the drain pump motor. (If the operation sound changes from continuous sound to intermittent sound, water is normally drained.) After the check, the drain pump motor runs, connecting the float switch connector. (In case of check by pulling out the float switch connector, be sure to return the connector to the original position.)
