SAFETY PRECAUTION

G Read the safety precautions carefully before operating the unit.
G 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.
WARNING
!
G 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.
G Please observe the instructions stated in the installation manual during the process of installation. Improper
installation may cause water leakage, electric shock and fire.
G 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.
G Observe the rules and regulations of the electrical installation and the methods described in the installation manual
when dealing with the electrical work. Use wire which is specified for the air conditioner. A short circuit and fire
may occur due to the use of low quality wire or improper work.
G 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 and fire.
G Please use the specified components for installation work. Otherwise, the units may collapse or water leakage,
electric shock and fire may occur.
G Do not mix any coolant other than R-22 into the cooling circulation path when mounting or shifting the unit. If it
is mixed with air, the high pressure in the circulation path will rise and this may result in broken copper pipes or
faults.
!
G Be sure to use the earth line. Do not place earth line near gas or water pipes, lightning conductor
and the earth line of telephone. Improper earthing may cause electric shocks.
G A circuit breaker should be installed depending on the mounting size of the unit. Without a circuit breaker, the
danger of electric shock exists.
G 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.
G Please ensure smooth flow of water when installing the drain hose.
1 Installation of Hanger, Wall Penetration and Installation of Protection Pipe
! CAUTION
G The draining of the water container inside the indoor unit can be done from the left.
Therefore the hanger must be fixed horizontally or slightly tilted towards the side of
drain hose. Otherwise, condensed water may overflow the water container.

(Please note the following matters and obtain permission from customer before installation).
G
The outdoor unit must be mounted at a location which can sup-
port heavy weight. Otherwise, noise and vibration will increase.
G
Do not expose the unit under direct sunshine or rain. Besides,
ventilation must be good and clear of obstruction.
G
The air blown out of the unit should not point directly to animals
or plants.
G
The clearances of the unit from top, left, right and front are specified
in figure below. At least three of the above sides must be open
air.
G
Be sure that the hot air blown out of the unit and noise do not
disturb the neighbourhood.
G
Do not install at a location where there is flammable gas, steam,
oil and smoke.
G
The location must be convenient for water drainage.
G
