	connection.

•After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual.

WARNING

•Ask your dealer or qualifi ed personnel to carry out installation work.

Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fi re.

•Install the air conditioner in accordance with the instructions in this installation manual.

Improper installation may result in water leakage, electric shocks or fi re.

•Be sure to use only the specifi ed accessories and parts for installation work.

Failure to use the specifi ed parts may result in the unit falling, water leakage, electric shocks or fi re.

•Install the air conditioner on a foundation strong enough to withstand the weight of the unit.

A foundation of insuffi cient strength may result in the equipment falling and causing injury.

•Electrical work must be performed in accordance with relevant local and national regulations and with instructions in this installation manual. Be sure to use a dedicated power supply circuit only.

Insuffi ciency of power circuit capacity and improper workmanship may result in electric shocks or fi re.

•Use a cable of suitable length.

Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fi re.

•Make sure that all wiring is secured, the specifi ed wires are used, and that there is no strain on the terminal connections or wires.

Improper connections or securing of wires may result in abnormal heat build-up or fi re.

•When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires so that the control box lid can be securely fastened.

Improper positioning of the control box lid may result in electric shocks, fi re or over heating terminals.

•If refrigerant gas leaks during installation, ventilate the area immediately.

Toxic gas may be produced if the refrigerant comes into contact with fi re.

•After completing installation, check for refrigerant gas leakage.

Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fi re, such as a fan heater, stove or cooker.

•When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specifi ed refrigerant (R32).

The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.

•During installation, attach the refrigerant piping securely before running the compressor.

If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.

•During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.

•Comply with national gas regulations.

CAUTION

•Do not install the air conditioner at any place where there is a danger of fl ammable gas leakage.

In the event of a gas leakage, build-up of gas near the air conditioner may cause a fi re to break out.

•While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation.

Improper drain piping may result in indoor water leakage and property damage.

•Tighten the fl are nut according to the specifi ed method such as with a torque wrench.

If the fl are nut is too tight, it may crack after prolonged use, causing refrigerant leakage.

•Take adequate steps to prevent the outdoor unit being used as a shelter by small animals.

Small animals making contact with electrical parts can cause malfunctions, smoke or fi re. Please instruct the customer to keep the area around the unit clean.

•The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are not thermally insulated.

•Only qualifi ed personnel can handle, fi ll, purge and dispose of the refrigerant.

Choosing an Installation Site

Before choosing the installation site, obtain user approval. 1. Indoor unit

• The indoor unit should be sited in a place where:

Including the mounting plate *

1)the restrictions on installation specifi ed in “Indoor/Outdoor Unit Installation Drawings” on page 6 are met,

2)both air inlet and outlet are free of obstructions,

3)the unit is not in the path of direct sunlight,

4)the unit is away from the source of heat or steam,

5)there is no source of machine oil vapour (this may shorten indoor unit life),

6)cool/warm air is circulated throughout the room,

7)the unit is away from electronic ignition type fl uorescent lamps (inverter or rapid start type) as they may shorten the remote control range,

8)the unit is at least 1m away from any television or radio set (unit may cause interference with the picture or sound),

9)space allows for the moving range of the fl ap in operation above curtain rails or other objects,

If (**) is 70mm or more, allow for 15mm of space from the indoor unit. If it is less than 15mm, this can affect the opening and closing of the shutter (bottom air inlet).

10)a height of 2.5m or more is allowed for installation,

Choosing an Installation Site

2.Wireless remote controller (When mounting on a wall etc.)

•Turn on all the fl uorescent lamps in the room, if any, and fi nd the site where remote control signals are properly received by the indoor unit (within 7m).

•Select a place where the remote controller is not hit by direct sunlight. (Selecting a place where direct sunlight hits the remote controller makes it diffi cult for the remote controller to receive the signal from the indoor unit.)

3.Outdoor unit

•The outdoor unit should be sited in a place where:

1)the restrictions on installation specifi ed in “Indoor/Outdoor Unit Installation Drawings” on page 6 are met,

2)the ground is solid enough to bear the weight and vibration of the unit and where the operating sound will not be amplifi ed,

3)the hot air discharged from the unit or the operating sound will not cause a nuisance to the neighbors of the user,

4)there is no bedroom or the like nearby, so that the operating sound will cause no trouble,

5)there are suffi cient spaces for carrying the unit into and out of the site,

6)both air inlet and outlet have clear paths of air (they should be free of snow in snowy districts),

7)there is no fear of infl ammable gas leakage in a nearby place,

8)units, power cords and inter-unit wires at least 3m away from television and radio sets (This is to prevent interference to images and sounds. Noises may be heard even if they are more than 3m away depending on radio wave conditions),

9)the unit is not directly exposed to salt, sulfi dized gases, or machine oil vapour (they may shorten outdoor unit life),

10)nothing which must be kept away from moisture is under the unit since drain fl ows out of the outdoor unit,

11)the air is clean, and there are no sources of unpleasant odours close by.

NOTE

Cannot be installed hanging from ceiling or stacked.

CAUTION

When operating the air conditioner in a low outdoor ambient temperature, be sure to follow the instructions described below.

•To prevent exposure to wind, install the outdoor unit with its suction side facing the wall.

•Never install the outdoor unit at a site where the suction side may be exposed directly to wind.

•To prevent exposure to wind, it is recommended to install a baffl e plate on the air discharge side of the outdoor unit.

•In heavy snowfall areas, select an installation site where the snow will not affect the unit.

• Construct a large canopy. • Construct a pedestal.

Install the unit high enough off the ground to prevent burying in snow.

Precautions for humidifying hose installation work

•When embedding G humidifying hose:

Cannot be installed to the existing embedded piping. Embedding work is separately necessary.

•The length of the G humidifying hose is marked on the hose packing material.

1)Use an extension hose (option) when extending the G humidifying hose.

2)The length of the G humidifying hose needs to be set to ensure humidifying capacity. Cut off any excess hose.

Use the remote controller to set the hose length. (Refer to “9. Setting the humidifying hose length” on page 16.)

•If the G humidifying hose needs to be cut to be laid, cut it, lay it, and connect it using the J joint included with the outdoor unit or an elbow (fi eld supply).When doing this, wrap it to prevent air leaks with the K binding band included with the outdoor unit.

(Refer to “4-2 Connecting the cut humidifying hoses” on page 8.)

•When laying the G humidifying hose inside the wall, block the ends of the G humidifying hose with tape or the like to prevent water or anything else from entering it until it is connected to the indoor unit and outdoor unit ducts.
