SAFETY PRECAUTIONS

The original instructions are written in English. All other languages are translations of the original instructions.

• Read these Safety Precautions carefully to ensure correct installation.

• This manual classifies the precautions into WARNING and CAUTION.
Be sure to follow all the precautions below: they are all important for ensuring safety.

WARNING

CAUTION .............. Failure to follow any of CAUTION may in some cases result in grave consequences.

• The following safety symbols are used throughout this manual:

Be sure to observe this instruction.

•

After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit
according to the Operation Manual.

...............Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.

Be sure to establish an earth connection. Never attempt.

WARNING

• Installation should be left to the dealer or another professional.

Improper installation may cause water leakage, electrical shock, or fire.

• Install the air conditioner according to the instructions given in this manual.

Incomplete installation may cause water leakage, electrical shock, or fire.

• Be sure to use only the specified accessories and spare 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 solid base that can support the weight of the unit.

An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.

• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring
rules or code of practice.

• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.

• For wiring, use a cable length enough to cover the entire distance with no connection.
Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.

(Failure to do so may cause abnormal heat, electric shock or fire.)

• Use the specified types of wires for electrical connections between the indoor and outdoor units.

Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.

• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force
on the electrical covers or panels.

Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire.

• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the
specified refrigerant (R410A), such as air.

(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)

• If any refrigerant has leaked out during the installation work, ventilate the room.

(The refrigerant produces a toxic gas if exposed to flames.)

• After all installation is complete, check to make sure that no refrigerant is leaking out.

(The refrigerant produces a toxic gas if exposed to flames.)

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

If the compressor is still running and the shut-off valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

Insufficient capacity or incomplete electrical work may cause electrical shock or fire.

English 1

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

If the compressor is not attached and the shut-off valve is open during pump-down, air will be sucked in when the compressor is run, causing
abnormal pressure in the freezer cycle which will lead to breakage and even injury.

• When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into
refrigeration cycle.

Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.

• Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.

Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.

• 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 in a place where there is danger of exposure to inflammable gas leakage.

If the gas leaks and builds up around the unit, it may catch fire.

• Establish drain piping according to the instructions of this manual.

Inadequate piping may cause flooding.

• Tighten the flare nut according to the specified method such as with a torque wrench.

If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.

• Only handle the indoor unit with gloves.

• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for
commercial and household use by lay persons.

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

• Sufficient clearance for maintenance and servicing is ensured.

• Piping between the indoor and outdoor units is within the allowable limits.
(Refer to the installation manual for the outdoor unit.)

• The indoor unit, outdoor unit, power supply wiring and transmission wiring is at least 1 meter away from televisions and radios. This
prevents image interference and noise in electrical appliances. (Noise may be generated depending on the conditions under which
the electric wave is generated, even if a one-meter allowance is maintained.)

• The equipment is not intended for use in a potentially explosive atmosphere.

Use suspension bolts to install the unit. Check whether or not the wall/floor is strong enough to support the weight of
the unit. If there is a risk that it is not strong enough, reinforce the wall/floor before installing the unit.

• To avoid contact with the fan, the following precaution action must be taken:

- Install the unit with ducting and grill which can only be removed with the aid of tooling. It shall be installed so that it

gives adequate protection against touching the fan. If a maintenance panel exists in the ducting, it shall only be
possible to remove the panel by the aid of tooling to avoid contact with the fan. The protection shall be according to
relevant European and local legislation. There are no restrictions concerning the installation height.

Select the signal receiver mounting location according to the following conditions:



• Install the signal receiver, which has a built-in temperature sensor, near the
intake vent where there is convection of air and it can get an accurate
reading of the room’s temperature. If the intake vent is in another room or
the unit cannot be installed near the intake vent for any other reason, install

ir discharge grille:
Wooden or plastic grille is recommended
because condensation may occur depending
on humidity conditions.

it 1.5m above the floor on a wall where there is convection.

• In order to get an accurate reading of the room’s temperature, install the
signal receiver in a location where it is not exposed directly to cold or hot air
from the air discharge grille or to direct sunlight.

• Since the receiver has a built-in light receptor to receive signals from the wireless remote
controller, do not mount it in a location where the signal may be blocked by a curtain, etc.

If the signal receiver is not installed in a location where there is convection of air, it may be unable to get an accurate reading of the room’s temperature.

• For remote controller installation, see the installation manual supplied with the remote controller.

• For outdoor unit installation, see the installation manual supplied with the outdoor unit.
