• Earth the air conditioner.

Do not connect the earth wiring to gas or water piping,
lightning conductor or telephone earth wiring.

Incomplete earthing may cause electric shocks or a fire.

• Be sure to install an earth leakage breaker.

Failure to do so may cause electric shocks and a fire.

• Disconnect the power supply before touching the electric

components.

If you touch the live part, you may get electric shocks.

• Make sure that all wiring is secure, using the specified

wirings and ensuring that external forces do not act on the

terminal connections or wirings.

Incomplete connection or fixing may cause an overheat or a

fire.

• When wiring between the indoor and outdoor units, and

wiring the power supply, form the wirings orderly so that the
control box lid can be securely fastened.

If the control box lid is not in place, overheating of the

terminals, electric shocks or a fire may be caused.

• If refrigerant gas leaks during installation work, ventilate the

area immediately.
Toxic gas may be produced if refrigerant gas comes into

contact with a fire.

• After completing the installation work, check to make sure

that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the

room and comes into contact with a source of a fire, such as
a fan heater, stove or cooker.

• Never directly touch any accidental leaking refrigerant. This

could result in severe wounds caused by frostbite.

• 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 (R32).
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.

• Do not allow children to climb on the outdoor unit and avoid

placing objects on the unit.

Injury may result if the unit becomes loose and falls.

• When flared joints are reused indoors, the flare part shall be

re-fabricated.

-�CAUTION------------

• Install drain piping according to this installation manual to

ensure good drainage, and insulate the piping to prevent
condensation.

Improper drain piping may cause water leakage, make the

furniture get wet.

• Install the air conditioner, power supply wiring, remote

controller wiring and transmission wiring at least 1 meter
away from televisions or radios to prevent image interference

or noise.

(Depending on the radio waves, a distance of 1 meter may

not be sufficient to eliminate the noise.)

• Install the indoor unit as far as possible from fluorescent

lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic lighting
type (inverter or rapid start type) fluorescent lamp is installed.

• Do not install the air conditioner in places such as the

following:

1. Where there is mist of oil, oil spray or vapour for example

a kitchen.

Resin parts may deteriorate, and fall out or water may leak.

2. Where corrosive gas, such as sulfurous acid gas, is

produced.

Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.

3. Where there is machinery which emits electromagnetic

waves.

Electromagnetic waves may disturb the control system,

and cause malfunction of the equipment.

4. Where flammable gases may leak, where carbon fibre

or ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
If the gas should leak and remain around the air

conditioner, it may cause ignition.

• The air conditioner is not intended for use in a potentially

explosive atmosphere.

• Pay careful attention when transporting the product.

Carry the product by the handle sections indicated on the
packaging material.
Do not hold the PP band since the PP band can become

loose and may result in danger.

• Do not touch the heat exchanger fins.

Inadvertently touching the fins can cause injury.

• 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.

• Install in a machine room that is free of moisture.

The unit is designed for indoor use.

• The refrigerant R32 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

R32 contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth's protection against
harmful ultraviolet radiation.
R32 will contribute only slightly to the greenhouse effect
if released into the atmosphere.

• Only qualified personnel can handle, fill, purge and dispose

of the refrigerant.

• Disposal requirements

- Dismantling of the unit, treatment of the refrigerant, of oil

and of other parts must be done in accordance with relevant
local and national legislation.

2. BEFORE INSTALLATION

When unpacking the indoor unit or moving the unit after

unpacked, hold the hangers (4 places) and do not apply

force to other parts (particularly refrigerant piping, drain

piping).

• Make sure to check in advance that the refrigerant to be

used for installation work is R32.
