English

• When wiring between the indoor and outdoor units, and wir-

ing the power supply, form the wirings orderly so that the con-
trol box cover can be securely fastened.
If the control box cover is not in place, overheat of the termi-
nals, electric shocks or a fire may be caused.

• If the supply cord is damaged, it must be replaced by the

manufacturer, a service agent or similarly qualified persons
in order to avoid a hazard.

• If refrigerant gas leaks during installation work, ventilate the

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

Instructions for equipment using R32 refrigerant

• Do NOT pierce or burn.
• Do NOT use means to accelerate the defrosting process or

to clean the equipment, other than those recommended by
the manufacturer.

• Be aware that R32 refrigerant does NOT contain an odour.
• The appliance shall be stored so as to prevent mechanical

damage and in a well-ventilated room without continuously
operating ignition sources (example: open flames, an operat-
ing gas appliance or an operating electric heater) and have a
room size as specified in “SELECTION OF INSTALLATION
LOCATION” on page 3.

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 con-

troller 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 light-
ing 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 cause them to fall out or
water to leak.

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

duced.
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 remained around the air condi-
tioner, it may cause ignition.

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

explosive atmosphere.

• Only use accessories, optional equipment and spare parts

made or approved by Daikin.

• Make sure the installation site withstands the unit's weight

and vibration.

• Use an all-pole disconnection type breaker with at least 3

mm between the contact point gaps that provide full discon-
nection under overvoltage category III.

BEFORE INSTALLATION

When unpacking and moving the indoor unit after
unpacked, do not apply force to the piping (refrigerant and
drain) and resin parts.

• If appliances are connected to the outdoor unit which contain

R32 refrigerant. Required floor area of the room in which
appliances are installed, operated and stored must follow
requirements in the installation manual of outdoor unit.

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

for installation work is according to the Outdoor Unit specifi-
cation.
(The air conditioner will not properly operate if a wrong refrig-
erant is used.)

• For installation of the outdoor unit, refer to the installation

manual attached to the outdoor unit.

• Do not throw away the accessories until the installation work

is completed.

• After the indoor unit is carried into the room, to avoid the

indoor unit from getting damaged, take measures to protect
the indoor unit with packing materials.
(1) Determine the route to carry the unit into the room.
(2) Do not unpack the unit until it is carried to the installation

location.
Where unpacking is unavoidable, use a sling of soft
material or protective plates together with a rope when
lifting, to avoid damage or scratches to the indoor units.

• Have the customer actually operate the air conditioner while

looking at the manual.
Instruct the customer how to operate the air conditioner (par-
ticularly cleaning of the air filters, operation procedures, and
temperature adjustment).

• For selection of installation location, use the installation pat-

tern paper (used in common with the packing case.) as refer-
ence.

• Do not use the air conditioner where in the salty atmosphere

such as coastal areas, vehicles, vessels or the voltage fluc-
tuation is frequent such as factories.

• Take off static electricity from the body when carrying out wir-

ing and the control box cover is removed.
The electric parts may be damaged.
