1. SAFETY PRECAUTIONS

Please read these “SAFETY PRECAUTIONS” carefully before installing air conditioning unit and be sure to
install it correctly. 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. Ask the
customer to store the installation manual along with the operation manual for future reference.

This air conditioner comes under the term “appliances not accessible to the general public”.

VRV System is a class A product. In a domestic environment this product may cause radio interference in
which case the user may be required to take adequate measures.

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

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.

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.

• When installing the unit in a small room, take measures against to keep refrigerant concentration

from exceeding allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can
lead to oxygen deficiency.

• 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.

1 English

• 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.

• Carry out the specified installation work after taking into account strong winds, typhoons or

earthquakes.
Failure to do so during installation work may result in the unit falling and causing accidents.

• Make sure that a separate power supply circuit is provided for this unit and that all electrical work

is carried out by qualified personnel according to local laws and regulations and this installation
manual.
An insufficient power supply capacity or improper electrical construction may lead to electric
shocks or fire.

• 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 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.

• Be sure to switch off the unit before touching any electrical parts.

• 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 EL. COMPO. BOX lid can be securely fastened.
Improper positioning of the EL. COMPO. BOX lid may result in electric shocks, fire or the terminals
overheating.

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

Toxic gas may be produced if the refrigerant gas 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.

• Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there

is a danger of frostbite.

CAUTION

•

Install the BS units, power cord and connecting wires at least 1 meter away from televisions or
radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to
eliminate noise.)

• Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with

electronic fluorescent lamps (inverter or rapid start types).
Install the BS unit as far away from fluorescent lamps as possible.

• 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.

• Do not install the air conditioner in the following locations:

1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water leakage could result.

2. Where corrosive gas, such as sulphurous acid gas, is produced.
Corroding of copper pipes or soldered parts may result in refrigerant leakage.

3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the control system and result in a
malfunction of the unit.

English 2

4. Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in
the air, or where volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.

5. Do not use in areas where the air is salty, such as along seacoasts, in factories or other areas
with significant voltage fluctuations, or in automobiles and watercraft.
Doing so could result in a malfunction.

CAUTION

The refrigerant R410A requires that strict precautions be observed for keeping the system
clean, dry and tightly sealed.
Clean and dry
Strict measures must be taken to keep impurities (including SUNISO oil and other mineral oils
as well as moisture) out of the system.
Tightly sealed
R410A contains no chlorine, does not destroy the ozone layer and so does not reduce the
earth’s protection against harmful ultraviolet radiation. R410A will contribute only slightly to the
greenhouse effect if released into the atmosphere. Therefore, sealing tightness is particularly
important in installation.
Carefully read the chapter “REFRIGERANT PIPING WORK” and strictly observe the correct
procedures.

3 English

2. BEFORE INSTALLATION

2-1 CAUTION CONCERNING NEW REFRIGERANT SERIES

• Since design pressure is 4.0 MPa or 40 bar (for R407C units: 3.3 MPa or 33 bar), the thickness of pipes

must be greater than previously. Since R410A is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state. (If the system is charged with refrigerant in its gaseous state, due to
composition change, the system will not function normally.)
The indoor/outdoor unit is designed for R410A. See the catalogue for indoor/outdoor unit models that can
be connected.
(Normal operation is not possible when connecting units that are originally designed for other refrigerants.

2-2 PRECAUTIONS

• Hold the unit by the Hanging brackets (4 points) when opening the box and moving it, and do not lift it

holding on to any other part especially the refrigerant piping.

• About installation of outdoor and indoor unit, refer to the installation manual provided with the outdoor and
the indoor unit.

•

This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment.
If installed as a household appliance it could cause electromagnetic interference.

2-3 ACCESSORIES

Check the following accessories are included with your unit.

NOTE

• Do not throw away any of the accessories until installation is complete.
