SAFETY PRECAUTION

● 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.
● Please request your sales agent or qualiÀ ed technician to install your unit. Water leakage, short circuit or À 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 installation may
cause water leakage, electric shock and À 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 power cables approved by the authorities of your country.
● Be sure to use the speciÀ ed 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 À re.
● Please use the speciÀ ed components for installation work. Otherwise, the units may collapse or water leakage, electric shock
and À re may occur.
● Be sure to use the speciÀ ed piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
● When installing or removing an air conditioner, only speciÀ ed refrigerant (R410A) shall be allowed, 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 À re, 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 À re in the fan-driven heater, space heater, etc., a poisonous gas may occur.
● Unauthorized modiÀ cations to the air conditioner may be dangerous. If a breakdown occurs please call a qualiÀ ed air conditioner
technician or electrician. Improper repairs may result in water leakage, electric shock and À re, etc.
● A circuit breaker or fuse (16A time delay) 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 Á ammable gas. The outdoor unit may catch À re if
Á ammable gas leaks around it.
Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist Á ows to the indoor unit. The oil
O
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.
● Please ensure smooth Á ow of water when installing the drain hose.
●
Piping shall be suitable supported with a maximum spacing of 1m between the supports.
1 Installation of Hanger, Wall Penetration and Installation of Protection Pipe
CAUTION
●
The draining of the water container inside the indoor unit can be done from the left.
Therefore the mounting plate must be À xed horizontally or slightly tilted towards the
side of drain hose. Otherwise, condensed water may overÁ ow the water container.
Direct Mounting On The Wall
●
Please use hidden beams in the wall to hold the mounting plate.
Procedures of Installation and Precautions
● Procedures to À x the mounting plate.
1. Drill holes on wall. 2. Push plug into the holes.
(As shown below) (As shown below)
● Procedures to À x the holder of remote control.
1. Drill holes on wall. 2. Push plug into the holes.
(As shown below) (As shown below)
Wall Penetration and Installation of Protection Pipe
●
Drill a ø 65mm hole on
wall which is slightly tilted
towards the outdoor side.
Drill the wall at a small
angle.
●
Cut the protection pipe
according to the wall
thickness.
● Empty gap in the sleeve
of protection pipe should
be completely sealed with
putty to avoid dripping of
rain water into the room.

WARNING
Be sure that the wire is not
in contact with any metal
in the wall. Please use
the protection pipe as wire
passing through the hollow
part of the wall so as to
prevent the possibility of
damaged by mouse.
Unless it seals completely,
any air with high humidity
flows from outdoor and
dew may drop.
CAUTION
THE CHOICE OF MOUNTING SITE
●
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.

(Please note the following matters and obtain permission from customer before installation).
WARNING
●
The outdoor unit must be mounted at a location which can support
heavy weight. Otherwise, noise and vibration will increase.
CAUTION
●
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 speciÀ ed in À gure
below. At least three 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
neighbourhood.
●
Do not install at a location where there is Á ammable gas, steam, oil and smoke.
● The location must be convenient for water drainage.
●
Place the outdoor unit and its connection wire at least 1m away from the
antenna or signal line of television, radio or telephone. This is to avoid noise
interference.
●
Do not install outdoor unit facing strong wind direction. It may damage the fan
motor.
● Do not install the outdoor unit in a place where small animals may build their
nests. If small animal goes inside the unit and touches the electrical parts,
failure of the unit, smoke or À re may be caused. Request your customer to
