Home 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 cables which are offi cially
approved in your country. Be sure to use the specifi ed circuit. A short circuit and fi re may
occur due to the use of low quality wire or improper work.
● Be sure to use the specifi ed cables 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 to prevent the external force is being applied to the connection section of the
terminal base. Improper insertion and loose contact may cause over-heating and fi re.
SPLIT UNIT AIR CONDITIONER
● Please use the specifi ed components for installation work. Otherwise, the units may collapse
or water leakage, electric shock, fi re or stronger vibration may occur.
INDOOR UNIT
● Be sure to use the specifi ed piping set for R32. Otherwise, this may result in broken copper

pipes or faults.
● When installing or transferring an air conditioner to another location, make sure that air
other than the specifi ed refrigerant(R32) does not enter the refrigeration cycle. If other air

should enter, the pressure level of the refrigeration cycle may increase abnormally which
could result in a rupture and injury.
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes

PERSONNEL ONLY ● 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 fi re in the fan-
driven heater, space heater, etc., a poisonous gas may occur.
● Unauthorized modifi cations to the air conditioner may be dangerous. If a breakdown occurs
please call a qualifi ed air conditioner technician or electrician. Improper repairs may result
in water leakage, electric shock and fi re, etc.

The draining of the water container inside the indoor unit can be done from the left. Therefore the hanger
●
must be fi xed horizontally or slightly tilted towards the side of drain hose. Otherwise, condensed water
may overfl ow the water container.

box for the direct connected power supply cables to the
outdoor unit. In case of other installations a main switch
with a contact gap or more than 3mm has to be installed.
Without a circuit breaker, the danger of electric shock
exists..
● Do not install the unit near a location where
there is fl ammable gas. The outdoor unit may
catch fi re if fl ammable gas leaks around it.
Please ensure smooth fl ow of water when installing the
●
drain hose. Improper installing may wet your furniture.
● An IEC approved power cord should be used. Power cord
type: NYM.
● The unit should be mounted at stable, non-vibratory location which can provide full support to the unit.
No nearby heat source and no obstruction near the air outlet is allowed.
●
● The clearance distances from top, right and left are specifi ed in fi gure below.
The location must be convenient for water drainage and pipe connection with the Outdoor unit.
●
● No nearby leakage risk of fl ammable gas, and no nearby source of vapor or oil smoke.
To avoid interference from noise, please place the unit and its remote controller at least 1m from the radio and television.
●
● 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 should be at least 2300 mm or more from the fl oor.
● The distance from the air outlet to the fi re alarm must be at least 1500mm and there must be no fi re alarm in the front
direction of the indoor unit.
