Please install the accessories attached with unit correctly according
to this installation manual.
Note:
1. At least two of A, B, C aspects are free from blocking.
2. When the Outdoor Unit is higher than the Indoor Units, to
prevent the rain from flowing into the indoor along the connection
pipe, a downward tipping arc should be made before the
connection pipe entering the wall to indoor to ensure the lowest
point on the connection pipe is at outdoor.
3. The illustration is for explanation purposes only. The actual
shape of would be slightly different (depend on models).
Cautions on remote controller installation
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.
Do not install the remote controller in a place exposed to direct
sunlight or close to a heating source, such as a stove.
Note that the positive and negative poles are right positions when
loading batteries.
Anchor bolts of out door unit installation
The outdoor unit should not be exposed to strong wind.
Fix the outdoor unit with Ø 10 or Ø 8 anchor bolts.

2. In case of brick, concrete or similar type walls, make 6 mm Ø, holes
in the wall. Insert clip anchors for appropriate mounting screws.
3. Fix the installation plate on the wall.
CAUTION:
• Connect the indoor unit first then the outdoor unit and bend and
arrange the pipe carefully.
• Do not allow the piping to let out from the back of the indoor
unit.
• Be careful not to let the drain hose slack.
• Insulate both of the auxiliary piping.
• Banding the drain hose under the auxiliary pipe.
• Do not allow the piping to let out from the back of the indoor
unit.
Piping and bandaging
Wind the connective cable, drain hose and wiring with tape
securely, evenly as shown below.
• Because the condensed water from rare of the indoor unit is
gathered in ponding box and is piped out of room. Do not put
anything else in the box.
Installation plate
2. Drilling a hole.
1. As diagram above determine the pipe hole position using
the installation plate, drill the pipe hole(Ø 65mm) so it slants
slightly downward.
2. Always use a wall hole conduit when piercing metal lath, ply
wood or metal plate.

CAUTION
• Perform the wiring with sufficient capacity. Installation places
legally require a short circuit isolator to be attached to prevent
electrical shock.
• Do not extend the power cable code by cutting.
• Power voltage should in the range of 90% 110% of rated voltage.
• The plug of the air conditioner takes a grounding leg, so clients
should use a grounding socket so that the air conditioner can be
grounded efficiently.
• If the power cord is damaged, replacement should be conducted
by qualified technician or a serviceman.
NOTE: Remark per EMC Directive 89/336/EEC
For to prevent flicker impressions during the start of the compressor
(technical process), following installation conditions do apply.
1. The power connection for the air conditioner has to be done at
the main power distribution.
The distribution has to be of an low impedance, normally the
required impedance reaches at a 32 A fusing point.
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 if restrictions do apply for products like
washing machines, air conditioner or electrical 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.

Outdoor installation precaution
Drain elbow installation
• Install the outdoor unit on a rigid base to prevent increasing noise
level and vibration.
• Determine the air outlet direction where the discharged air is no
blocked.
• In the case that the installation place is exposed to strong wind
such as a seaside operation by putting the unit lengthwise along
the wall or using a dust or shield plates.
• Specially in windy area, install the unit to prevent the admission of
wind. The connection between bracket and wall, bracket and the
air conditioner should be firm, stable and reliable.
• If need suspending installation, the installation bracket should
accord with technique requirement in the installation bracket
diagram.
Fit the seal into the drain elbow, then insert the drain elbow
into the base pan hole of outdoor unit, rotate 90 to securely
assemble them. Connecting the drain elbow with an extension
drain hose (Locally purchased), in case of the water draining off
the outdoor unit during the heating mode.

When Using the Vacuum Pump
(For method of using a manifold valve, refer to its operation manual.)
1. Completely tighten the flare nuts, A, B, C, D, connect the
manifold valve charge hose to a charge port of the packed valve
on the gas pipe side.
2. Connect the charge hose connection to the vacuum pump.
3. Fully open the handle Lo of the manifold valve.
4. Operate the vacuum pump to evacuate. After starting
evacuation, slightly loose the flare nut of the packed valve on the
gas pipe side and check that the air is entering.(Operation noise
of the vacuum pump changes and a compound meter
indicates 0 instead of minus)
5. After the evacuation is complete, fully close the handle Lo of
the manifold valve and stop the operation of the vacuum pump.
• Make evacuation for 15 minutes and more and check that
the compound meter indicates -76cmHg(-1.0x105Pa).
6. Disconnect the charge hose from the charge connection of the
packed valve at the gas pipe side.
7. Fully open the packed valve stems B and A.
8. Securely tighten the cap of the packed valve.
Manual switch
Auto/cool
1. Connect the power, push the “ON/OFF” button on the remote
controller to begin testing.
2. Push mode button, select cooling, heating, fan mode to check if
all functions work well.
3. When the ambient temperature is too low (below temperatures
of 17°), the unit can't be controlled by the remote controller to
run at cooling mode. At this time, manual operation can be taken
to select cooling mode.
4. Be sure to set the manual switch on OFF after finishing the test
operation. Then installer should explain how to manipulate, fix,
and maintain their air conditioner. Also tell them that regular check
of the installation bracket and maintenance are necessary.
Clients should apply for inspecting to relevant department so as
to ensure the air conditioner can operate normally, safety and
reliably.
