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

• 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.

• Before touching electrical parts, turn off the power.
Failure to turn off the power may result in electric shocks.

• Make sure that all wiring is secured, the specified wires are used,
and no external forces act on the terminal connections or wires.
Improper connections or installation may result in the terminals
overheating or fire.

• When wiring the power supply and connecting the remote control­ler wiring and transmission wiring, 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 or fire.

• If the 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 the installation work, check that the refrigerant
gas does not leak.
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 the refrigerant leaked from refrigerant piping
connections.
Frostbite may be caused.

• Do not allow children to mount on the outdoor unit, or avoid
placing any object on it. Falling or tumble may result in injury.

Caution

• While following the instructions in this installation manual,

install drain piping in order to ensure proper drainage and insu­late piping in order to prevent condensation.
Improper drain piping may result in water leakage and property
damage.

• Install the indoor, BS and outdoor units, power supply wiring and
connecting wiring at least 1 meter away from televisions or radios
in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be
sufficient enough to eliminate the noise.)

Installation manual

1 English

• The indoor and BS unit should be installed as far away from fluo­rescent lighting as possible.
Remote controller (wireless kit) transmitting distance can result
shorter than expected in rooms with electronic fluorescent lamps
(inverter or rapid start types).

• Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an oil spray or vapor is produced,

for example in a kitchen.
Plastic parts may deteriorate and fall off or result in water leakage.

(b) where corrosive gas, such as sulfurous acid gas, is produced.

Corroding copper pipes or soldered parts may result in refrig­erant leakage.

(c) near machinery emitting electromagnetic waves.

Electromagnetic waves may disturb the operation of the con­trol system and result in a malfunction of the unit.

(d) where flammable gas may leak, where there are carbon fiber

or ignitable dust suspensions in the air, or where volatile flam­mables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.

(e) Locations where small animals might build nests inside the unit.

If small animals enter and come in contact with electrical parts,
this can cause malfunctions, smoke, and fire.

[DESIGN PRESSURE]

Since design pressure is 4.0MPa or 40bar (for R407C units : 3.3MPa
or 33bar), the wall thickness of pipes should be more carefully selected
in accordance with the relevant local and national regulations.

1-2 Special notice of product

[CLASSIFICATION]

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

[EMC CHARACTERISTICS]

VRVIII 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.

[REFRIGERANT]
VRVIII System use R410A refrigerant.

• The refrigerant R410A requires strict cautions for keeping the sys-

tem clean, dry and tight.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A.Clean and dry

Foreign materials (including mineral oils such as SUNISO oil or
moisture) should be prevented from getting mixed into the system.

B.Tight

Take care to keep the system tight when installing.
R410A does not contain any chlorine, does not destroy the
ozone layer, and does not reduce the earth’s protection against
harmful ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is
released.

• Since R410A is a mixed refrigerant, the required additional refrig­erant must be charged in its liquid state. If the refrigerant is
charged in a state of gas, its composition changes and the system
will not work properly.

Limit by the total maximum refrigerant charge

The total maximum refrigerant charge of a VRVIII system must be
below 100kg, this to be in accordance with CE requirement
(EN60335-2-40 standard).
This means that in case the total maximum refrigerant charge of the
system (factory and additional charge) is equal to or more than
100kg you must divide your multiple outdoor system into smaller
independent systems, each containing less than 100kg refrigerant
charge.
For factory charge, refer to the unit name plate.

Important information regarding the refrigerant used

This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
