Carefully read through the procedures of proper
installation before starting installation work.
The sales agent should inform customers regarding
the correct operation of installation.
Tools Needed For Installation Work
Read the safety precautions carefully before operating the unit.
The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
WARNING ........ Incorrect methods of installation may cause death or serious injury.
CAUTION ......... Improper installation may result in serious consequence.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper way of operating
the unit as described in the user’s guide.
A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
A main switch with a contact gap of more than 3mm has to be installed in the power supply line to the outdoor unit.
Do not install the unit near a location where there is flammable gas. The outdoor unit may
catch fire if flammable gas leaks around it.
Please ensure smooth flow of water when installing the drain hose.
Piping shall be suitable supported with a maximum spacing of 1m between the supports.
Please request your sales agent or qualified technician to install your unit. Water leakage, short circuit or fire may occur if you
do the installation work yourself.
Please observe the instructions stated in the installation manual during the process of installation. Improper installation may
cause water leakage, electric shock and fire.
Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the
units may collapse and impose danger.
Observe the rules and regulations of the electrical installation and the methods described in the installation manual when
dealing with the electrical work. Use power cables approved by the authorities of your country.
Be sure to use the specified wire for connecting the indoor and outdoor units. Please ensure that the connections are tight
after the conductors of the wire are inserted into the terminals. Improper insertion and loose contact may cause over-heating
Please use the specified components for installation work. Otherwise, the units may collapse or water leakage, electric shock
and fire may occur.
Be sure to use the specified piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigeration cycle. Otherwise,
pressure in the refrigeration cycle may become abnormally high so that a rupture may be caused.
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fire, a poisonous
gas may occur.
After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks
into the room, coming into contact with fire in the fan-driven heater, space heater, etc., a poisonous gas may occur.
Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner
technician or electrician. Improper repairs may result in water leakage, electric shock and fire, etc.
FOR SERVICE PERSONNEL ONLY
THE CHOICE OF MOUNTING SITE (Please note the following matters and obtain permission from customer before installation).
The unit should be mounted at stable, non-vibratory location which
can provide full support to the unit.
The Outdoor unit must be mounted at a location which can sup-
port heavy weight. Otherwise, noise and vibration will increase.
No nearby heat source and no obstruction near the air outlet is
The clearance distances from top, right and left are specified in
The location must be convenient for water drainage and pipe
connection with the Outdoor unit.
To avoid interference from noise please place the unit and its
remote controller at least 1m from the radio, television and inverter
type fluorescent lamp.
To avoid any error in signal transmission from the remote controller,
please put the controller far away from high-frequency machines
and high-power wireless systems.
The installation height of indoor unit must be 2.3m or more in a
non public area.
Do not expose the unit under direct sunshine or rain. Besides, ventilation
must be good and clear of obstruction.
The air blown out of the unit should not point directly to animals or plants.
The clearances of the unit from top, left, right and front are specified in
figure below. At least 3 of the above sides must be open air.
Be sure that the hot air blown out of the unit and noise do not disturb the
Do not install at a location where there is flammable gas, steam, oil and
