Cautions

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.
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.

Before installation, operate the remote controller
to determine its location in a reception range.
Keep the remote controller at least 1m apart from
the nearest TV set or stereo equipment. (It is
necessary to prevent image disturbances or
noise interferences.)
Do not install the remote controller in a place
exposed to direct sunlight or close to a heating
source, such as a stove.

INSTALL THE CONNECTING PIPE
Do not let air, dust, or other impurities fall in the pipe system during the time of installation.
The connecting pipe should not be installed until the indoor and outdoor units have been
fixed already.
Keep the connecting pipe dry, and do not let moisture in during installation.
1) Connect the indoor unit at first, then the outdoor unit.
Bend the tubing in proper way. Don,t harm them.
The Procedure of Connecting Pipes
1. Measure the necessary length of the connecting pipe, and make it by the following way.
Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4
rounds with hands before fasten the flare nuts. (Refer to chart 12)
Be sure to use two wrenches simultaneously when you connect or disconnect the pipes.
Cautions
2) The stop valve of the outdoor unit should be closed absolutely (as original state). Every
time you connect it, first loosen the nuts at the part of stop valve, then connect the flare
pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts
and other impurities may enter the pipe system and may cause malfunction later. So
please expel the air out of the pipe with refrigerant before connection.
The bending angle should not exceed 90 C
Bending position is preferably in the bendable pipe. The larger the better it is .
Do not bend the pipe more than three times.
o
3) Expel the air (refer to the Expel The Air ) after connecting the refrigerant pipe with the
indoor unit and the outdoor unit.
Then fasten the nuts at the repair-points.
Notices For Benable pipe.
Cut out a desired concave at the bending part of the insulating pipe.
Then expose the pipe(cover it with tapes after bending).
To prevent collapsing of deforming, please bend the pipe at its biggest radius.
Use bender to get a small radius pipes.
Bend the connecting pipe of small wall thickness.
8

Be sure to use the same insulating materials when you buy the brass pipe. (More than
9mm thick)
Use the market brass pipe.
Chart 11 Chart 12 Chart 13
Use frozen oil
Bend the pipe with thumb
Min-radius 100mm
Make the ends
straight
2. Locate The Pipe
1) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then
set on the fittings such as the wall conduit and its cover.
2) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air
in, which will cause water leakage by condensation.
3) Pass the bound connecting pipe through the wall conduit from outside. Be careful of the
pipe allocation to do no damage to the tubing.
3. Connect the pipes.
4. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe conne-
cting the indoor unit with the outdoor unit fluently flow.
5. Be sure of no leakage by checking it with leak detector or soap water.
6. Cover the joint of the connecting pipe to the indoor unit with the soundproof/insulating
sheath (fittings), and bind it well with the tapes to prevent leakage.
9

The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as
the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make sure there is no leakage.
With the connection part to the indoor unit, please be noted not to impose pressure on the
side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100, there should not be any win
ding.
The total length of the drain pipe when pulled out traversely shall not exceed 20m, when
the pipe is over long, a prop stand must be installed to prevent winding.
Refer to the figures on the right for the installation of the pipes.

Be sure to Install Current Leakage Protection Switch, Or electric shock may occur.
Power cord is to be selected according to national regulations.
Outdoor unit power cord should be selected and connected according to the outdoor unit
installation manual.
Wiring should be away from high temperature components, or the insulation layer of the
wires may melt down.
Use wire clamp to fix the wires and terminal block after connection.
Control wire should be wrapped together with heat insulated refrigerant pipes.
Connect the indoor unit to power only after the refrigerant has been vacuumed.
CAUTION

DE - COMMISSIONING DISMANTLING & DISPOSAL
This product contains refrigerant under pressure, rotating parts, and electrical connections which
may be a danger and cause injury!
All work must only be carried out by competent persons using suitable protective clothing and safety precautions.
1. Isolate all sources of electrical supply to the unit including any control system supplies switched by the unit. Ensure that all points of electrical and gas
isolation are secured in the OFF position. The supply cables and gas pipework may then be disconnected and removed. For points of connection refer
to unit installation instructions.
2. Remove all refrigerant from each system of the unit into a suitable container using a refrigerant reclaim or recovery unit. This refrigerant may then be
re-used, if appropriate, or returned to the manufacturer for disposal.
Under No circumstances should refrigerant be vented to atmosphere. Where
appropriate, drain the refrigerant oil from each system into a suitable container and dispose of according to local laws and regulations governing
disposal of oily wastes.
3. Packaged unit can generally be removed in one piece after disconnection as above. Any fixing down bolts should be removed and then unit lifted from
position using the points provided and equipment of adequate lifting capacity. Reference MUST be made to the unit installation instructions for unit
weight and correct methods of lifting. Note that any residual or spilt refrigerant oil should be mopped up and disposed of as described above.
4. After removal from position the unit parts may be disposed of according to local laws and regulations.
