SAFETY CONSIDERATIONS
Please read the “SAFETY CONSIDERATIONS” carefully
before installing the air-conditioner equipment and be
sure to install it correctly.
The below notes include two types, both of which are
related to safety and extremely important. Please read
it carefully.
WARNING
hazardous situation, which, if not avoided, could result
in death or serious injury.
CAUTION……Indicates a situation that may
result in injury or equipment damage. According to
different conditions, it also may result in the accidents
of serious injury or other damage.
Ask the specially trained personnel to carry out
the installation work. Do not try to install the
machine by yourself.
Please perform the installation work in accordance
with the steps in this manual.
Improper installation may result in water leakage,
electric shock or fire.
Make sure that a separate power supply circuit is
provided for this unit and that all electrical work is
carried out by specially trained personnel
according local laws, regulations and this
installation manual.
An insufficient power supply capacity or improper
electrical construction may lead to electric shock
or fire.
Make sure that the specified wires that comply
with national standard are used and all wiring is
secure. No external forces act on the terminal
connections or wires.
Improper wiring connections or installation may
result in electric shock or fire.
When connecting the wiring of power supply,
wired controller and remote controller, the wiring
should be laid orderly so that the electric parts
box lid can be securely fastened.
If it appears refrigerant leakage during the
installation process, open the doors and windows
immediately to ventilate the room thoroughly.
Toxic gas may be produced if the refrigerant comes
in contact with fire such as a fan heater, stove or
cooking device.
Power off the unit before touching the electrical
parts.
Do not touch the switch with wet fingers.
Touching the switch with wet fingers may cause
electric shock.

WARNING
Indicates a potentially
VRF Air-Conditioner IOM
Be sure the air-conditioner is well grounded.
Never connect the ground line with the gas pipe,
water pipe, lightning conductor or telephone lines.
Incomplete ground line may cause electric shock
or fire.
Be sure to install a ground leakage breaker.
Failure to install a ground leakage breaker may
result in electric shock or fire.
Please follow the instructions in this manual to
install drain pipe in order to ensure smooth
drainage and good piping insulation to avoid
accumulating of condensate water.
Improper drain pipe may result in water leakage
and property damage.
Install the air-conditioner unit, power supply
wiring and connection wires at least 1m away
from electrical equipments, such as TVs, radios,
etc. to avoid electromagnetic waves interference
or noise.
Remote controller transmitting distance may be
shortened than the expected one in the rooms
with electronic fluorescent lamps (inverter or
rapid start types).
Install the indoor unit as far away from fluorescent
lamps as possible.
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 be deteriorated, corroded or
damaged.
(b) Where corrosive gas, such as sulfurous acid
gas is produced.
Corroded copper tubes or soldered parts may
result in refrigerant leakage.
(c) Where near machinery emitting
electromagnetic waves.
Electromagnetic waves may disturb the
operation of the control system and result in a
malfunction of the equipment.
(d) Where it may have flammable gas leakage,
carboform or floating flammable dust,
volatile flammable material such as gasoline
or thinner.
Using air-conditioner in those places may
result in fire.
Do not touch heat exchanger fins
Improper touching the heat exchanger fins may
result in machine damage or personnel injury.
Be very careful about the product transportation.
Do not use any packaging PP bands for a means of
transportation to avoid PP bands rupturing and
result in product damaging or personnel injury.

BEFORE INSTALLATION
Do not unpack the unit before reaching the
installation site. Where unpacking is unavoidable,
countermeasure should be done after unpacking
