(ø65mm)
1. Determine the position of the pipe and drain hose hole
using the right figure and drill the hole with an inner
diameter of 65mm so that it slants slightly downwards.
2. If you are fixing the indoor unit to a… Then follow Steps…
Wall 3.
Window frame 4 to 6.
3. Fix the installation plate to the wall in a manner appropriate to the weight of the indoor unit.
If you are mounting the plate on a concrete wall with
anchor bolts, the anchor bolts must not project by more
than 20mm.
4. Determine the positions of the wooden uprights to be
attached to the window frame.
3-2-2(b) Purging the Unit
5. Attach the wooden uprights to the window frame in a
manner appropriate to the weight of the indoor unit.
6. Using tapped screws, attach the installation plate to the
wooden uprights, as illustrated in the last figure opposite.
On delivery, the indoor unit is loaded with an inert gas.
All this gas must therefore be purged before connecting the
assembly piping. To purge the inert gas, proceed as fol lows.
Unscrew the caps at the end of each pipe.
Result : All inert gas escapes from the indoor unit.
• To prevent dirt or foreign objects from getting into
the pipes during installation, do NOT remove the
caps completely until you are ready to connect the
piping.

3-2-2(c) Connecting the Assembly Cable.
The outdoor unit is powered from the indoor unit via the assembly
cable. If the outdoor unit is more than five metres away from the
indoor unit, the cable must first be extended to a maximum of
ten metre s .
1 . Extend the assembly cable if necessary.
2 . Open the front grille by pulling on the tabs on the lower right and
left sides of the indoor unit.
3 . Remove the screw securing the connector cover.
4 . Pass the assembly cable through the rear of the indoor unit and
connect the assembly cable to terminals 1 to 5.
• Each wire is labelled with the corresponding terminal number.
5 . Pass the other end of the cable through the 65mm hole in the wall.
6 . Replace the connector cover, carefully tightening the scre w.
7 . Close the front grille.
8 . For further details on how to plug the other end of the assembly
cable into the outdoor unit, refer to page 3-10.
Operating Instructions and Installation
3-2-2(d) Installing and Connecting the Indoor Unit Drain Hose
C a re must be taken when installing the drain hose for the indoor unit to ensure that any condensa tion water is correctly drained outside.l When passing the drain hose through the 65mm hole drilled
in the wall, check that none of the following situations occur.
The hose must
NOT slope upw
ards.
To install the drain hose, proceed as follows.
1. If necessary, connect the 2-metre extension to the drain hose.
2 . If you are using the extension, insulate the inside part of the extension drain hose with a shield.
3. Pass the drain hose under the refrigerant piping, taking care to keep the drain hose tight.
4. Pass the drain hose through the hole in the wall, making sure that it is sloping downwards, as
shown in the illustrations above.
The end of the drain
hose must NOT be
placed in water.
Do NOT bend the
hose in different
directions.
Keep a clearance of at
least 5cm between the
end of the hose and the
ground.
Do NOT place the end
of the drain hose in a
hollow.

3-2-2(g) Air-Purging
CAUTION
The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor,
reduce to cooling/heating capacity and could lead to a malfuction. Refrigerant for air purging is not charged in the outdoor unit.
Use Vacuum Pump as shown at the right figure. Each unit must be purged in turn.
1. Check the piping connections
2. Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service
port(3/8” or 1/2” Packed valve) as shown at the right
figure.
3. Open the valve of the low pressure side of manifold
gauge counter-clockwise.
4. Purge the air from the system using vacuum pump for
about 10 minutes.
-Close the valve of the low pressure side of manifold
gauge clockwise.
-Make sure that pressure gauge show -0.1MPa
(-76cmHg) after about 10minutes.
This procedure is very important in order to avoid gas
leak.
-Turn off the vacuum pump.
- Remove the hose of the low pressure side of manifold
gauge.
5. Set valve cork of both liquid side and gas side of
packed valve to the open position.
6. Mount the valve stem nuts and the service port cap to
the valve, and tighten them at the torque of 18N•m
with a torque wrench.

3-2-2(h) Refrigerant Refill Procedure
If connecting pipe of more than 10 metres is installed, additional refrigerant should be charged by
extra metre. You don’t have to charge additional refrigerant up to 10 metres of connecting pipe.
1 . Remove the valve stem cap and service
port of 3-way valve.
2 . Connect the charging hose of low pre s s u re
side of Manifold gauge to the packed valve
having a charging port(3/8” Packed valve)
as shown at the right figure .
3 . Operate the unit at the cooling mode.
4 . Slowly open the valve of the low pre s s u re
side of Manifold gauge counterc l o c k w i s e
until the low pre s s u re of manifold gauge
indicates 4.8 to 5.5 kg/cm2at the high cool
operation(1-unit operation) and the stand a rd temperature.(for details, see the page
3 - 1 4 )
It is recommend that regrigerant should be
slowly put in. If the refrigerant is put in
too quickly, compressor will be damaged.
5 . Stop operation of the air conditioner.

valves are set to the open position.
(1) Remove the valve stem caps.
(2) Be sure to use a hexagonal wrench to
operate the Gas side valve stems.
2 . Operate the unit for 10 to 15 minutes.
3 . Stop operation and wait for 3 minutes, then
connect the charge set to the service port of
the 3-way valve.
(1) Connect the charge hose with the push
pin to the service port.
4 . Air purging of the charge hose.
(1) Open the low-pre s s u re valve on the
c h a rge set slightly to air purge from the
c h a rge hose.

6 . Operate the air conditioner at the cooling
cycle and stop operation immediately after
setting the 3-way valve to the closed position
when the gauge indicates 0 kg/cm2G .
If the unit can not be operated at the Cooling
Mode(weather is rather cool), operate the
unit at the Trubo Mode. So that the unit can
be operated.
7 . Disconnect the charge set, and mount the
both 3-way valve’s stem nuts and the service

1. Carry out the pump down pro c e d u re
( refer to the details of ‘pump down’).
2. Remove the power cord .
3. Disconnect the assembly cable from the
indoor and outdoor units.
4. Remove the flare nut connecting the indoor
unit and the pipe.
At this time, cover the pipe of the indoor
unit and the other pipe using a cap or vinyl
plug to avoid foreign material entering.
3-Way Valve
5. Disconnect the pipe connected to the outdoor
