Notes Before Installation
1. Select the correct carry-in path.
2. Move this unit as originally packaged as possible.
3. If the air conditioner is installed on a metal part of the building, it must be electrically
insulated according to the relevant standards to electrical appliances.
e. In buses or cabinets.
f. In kitchen where it is full of oil gas.
g. There is strong electromagnetic wave existing.
h. There are inflammable materials or gas.
i. There is acid or alkaline liquid evaporating.
j. Other special conditions.
NOTE:
Remark per EMC Directive 89/336/EEC
For to prevent flicker impressions during the start of the compressor (technical process),
following installation conditions apply.
1. The power connection for the air conditioner has to be done at the main power distribution.
The distribution has to be of a low impedance, normally the required impedance reaches
a 32A fusing point.at
2. No other equipment has to be connected with this power line.
3. For detailed installation acceptance, please refer to your contract with the power supplier
restrictions do apply for products like washing machines, air conditioners or electricalif
ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.
5. For any question contact your local dealer.

INDOOR UNIT INSTALLATION
Carry out the pipe and line operation in the ceiling after finishing the installation of the main
body. While choosing where to start the operation, determine the direction of the pipes to
be drawn out. Especially in case there is a ceiling, position the refrigerant pipes, drain pipes,
indoor & outdoor lines to the connection places before hanging up the machine.
The installation of hanging screw bolts.
Wooden construction
Installing f10 hanging screw bolts. (4 bolts)
Please refer to the following figure for the distance measurement between the screw bolts.
Please install with f10 hanging screw bolts.
The handling to the ceiling varies from the constructions, consult the construction personn-
els for the specific procedures.
1. The size of the ceiling to be handled ... ... do keep the ceiling flat. Consolidate the roof
beam for possible vibration.
2. Cut off the roof beam.
3. Strengthen the place cut off, and consolidate the roof beam.
Put the square timber traversely over the
roof beam, then install the hanging screw
bolts. (Refer to Chart 1)

Necessary Room For Installation And Maintenance (Refer to Chart 13)
Moving And Installing
If possible, please remove the obstacles nearby to prevent the performance from being
impeded by too little of air circulation. Leave open two of the three directions(A,B,C).
Since the gravity center of this unit is not at its physical center, so please be careful when
lifting it with a sling.
Never hold the air-in of the outdoor unit to prevent it from deforming.
Do not touch the fan with hands or other objects.
o
Do not lean it more than 45 , and do not lay it sidelong.
OUTDOOR UNIT INSTALLATION
Keep this unit away from direct radiation of the sun or other heaters. If unavoidable, please
cover it with a shelter.
In places near coast or with a high attitude where the wind is strong, please install the
outdoor unit against the wall to ensure normal performance.
Use a baffle when necessary.
In the case of extremely strong wind, please prevent the air from flowing backwards into
the outdoor unit. (Refer to chart 12)
Locate the outdoor unit as close to the indoor unit as possible.
The minimum distance between the outdoor unit
and obstacles described in the installation chart
does not mean that the same is applicable to the
situation of an airtight. Leave open two of three
directions A , B, C.
