Safety Precautions

• The precautions described herein are classified as WARNING and CAUTION. They both contain important informa­tion regarding safety. Be sure to observe all precautions without fail.

• Meaning of WARNING and CAUTION notices

WARNING ....Failure to follow these instructions properly may result in personal injury or loss of life.

CAUTION .....Failure to observe these instructions properly may result in property damage or personal injury, which

may be serious depending on the circumstances.

• The safety marks shown in this manual have the following meanings:

Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt.

• 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 qualified 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 fire.

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

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

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

Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.

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

A foundation of insufficient 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.

Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire.

• Use a cable of suitable length.

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

• Make sure that all wiring is secured, the specified 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 fire.

• 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, fire 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 fire.

• 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 fire, 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 specified refrigerant (R410A).

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.

• Be sure to earth the air conditioner. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead.

Imperfect earthing may result in electric shocks.

• Be sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in electric shocks or fire.

CAUTION

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

In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire 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 flare nut according to the specified method such as with a torque wrench.

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

• Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.

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

• Sound pressure level is less than 70dB(A).

Precautions for Selecting the Location

1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.

2) Choose a location where the hot air discharged from the unit or the operation noise, will not cause a nuisance to the neighbors of the user.

3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.

4) There must be sufficient spaces for carrying the unit into and out of the site.

5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.

6) The site must be free from the possibility of flammable gas leakage in a nearby place. Locate the unit so that the noise and the discharged hot air will not annoy the neighbors.

7) Install 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.)

8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air condi­tioner.

9) Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away from moisture.

NOTE:

Cannot be installed hanging from ceiling or stacked.

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 baffle
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.

250mm from wall

Allow space for piping
and electrical servicing.

Level mounting base
(optional parts)

Clamping material

Insulation tube

Service lid

Tape

Also insulate the connection on the outdoor unit.

Use tape or insulating material on all connections
to prevent air from getting in between the copper
piping and the insulation tube.
Be sure to do this if the outdoor unit is installed
above.

Cut thermal insulation
pipe to an appropriate
length and wrap it with
tape, making sure that no
gap is left in the insulation
pipe’s cut line.

Wrap the insulation
pipe with the finishing
tape from bottom to top.

Caulk

with putty.

Allow 300mm of
work space below
the ceiling surface.

If there is the danger of the unit falling
or overturning, fix the unit with
foundation bolts, or with wire or other
means.

If the location does not have good
drainage, place the unit on a level
mounting base (or a plastic pedestal).
Install the outdoor unit in a level
position. Failure to do so may result in
water leakage or accumulation.

Installation Drawings

For installation of the indoor units, refer to the installation manual which was provided with the units.
(The diagram shows a wall-mounted indoor unit.)

• Do not connect the embedded branch piping and the outdoor unit when only carrying out piping work without connecting the
indoor unit in order to add another indoor unit later.
Make sure no dirt or moisture gets into either side of the embedded branch piping.
See “Precautions for Laying Refrigerant Piping” on page 9 for details.

• It is impossible to connect the indoor unit for one room only. Be sure to connect at least 2 rooms.
