●
Please request your sales agent or qualifi ed technician to install your unit. Water leakage, short circuit
or fi re may occur if you do the installation work yourself.
●
Please observe the instructions stated in the installation manual during the process of installation. Improper
Home installation may cause water leakage, electric shock and fi re.
●
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 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

● 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.

The Choice of Mounting Site
(Please note the following matters and obtain permission from customer before installation).
CAUTION
!
● A circuit breaker must be installed in the house distribution 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 4/32" (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.
Piping shall be suitable supported with a maximum spacing of
●
3-9/32' (1m) between the supports.
● Please ensure fi eld selected electrical components (switches,
wires, etc) are following approved local regulation requirements.
● 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 3.28ft(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 90-18/32" (2300mm) or more from the fl oor.
The distance from the air outlet to the fi re alarm must be at least 59-2/32" (1500mm) and there must be no fi re alarm in the
●
front direction of the indoor unit.
Do not install the indoor unit in a machine shop, kitchen and laundry rooms when vapor from oil or its mist fl ows to the indoor
●
unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may deform and in the
worst case, break the plastic parts of the indoor unit.
