Safety Precautions
The following safety precautions must be taken when using your air conditioner.
WARNING Risk of electric shock. • Can cause injury or death. • Disconnect all
remote electric power supplies before servicing, installing or cleaning.
• This must be done by the manufacturer or its service agent or a similar
qualified person in order to avoid a hazard.
 The unit should not be installed by the user. Ask the dealer or
authorized company to install the units except room air conditioners
for the U.S.A and Canada area.
 If the unit is installed improperly, water leakage, electric shock or fire
may result.
 Mount with the lowest moving parts at least 2.5m above the floor or
grade level. (If applicable)
 The manufacturer does not assume responsibility for accidents or injury
caused by an incorrectly installed air conditioner. If you are unsure
about installation, contact an installation specialist.
 When installing the built-in type air conditioner, keep all electrical
cables such as the power cable and the connection cord in pipe, ducts,
cable channels e.t.c to protect them against liquids, outside impacts
and so on.
INSTALLING THE UNIT
 If the power cord of this air conditioner is damaged, it must be replaced
by the manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
 The unit must be plugged into an independent circuit if applicable or
connect the power cable to the auxiliary circuit breaker. An all pole
disconnection from the power supply must be incorporated in the fixed
wiring with a contact opening of >3mm.
 Do not use an extension cord with this product.
 If the unit is equipped with a power supply cord and a plug, the plug
must be accessible after installation.
 The air conditioner must be installed in accordance with national wiring
regulations and safety regulations wherever applicable.

Preparation for Installation
When deciding on the location of the air conditioner with the owner,
the following restrictions must be taken into account.
General
Do NOT install the air conditioner in a location where it will come into contact
with the following elements:
 Combustible gases
 Saline air
 Machine oil
 Sulphide gas
 Special environmental conditions
If you must install the unit in such conditions, first consult your dealer.
Accessories
 The following accessories are supplied with the indoor unit.
The type and quantity may differ depending on the specifications.
Pattern sheet Insulation cover drain Insulation Insulation cover band
Insulation pipe Insulation drain hose Cable-tie Flexible hose
M4x12 tapped Screw Pad stopper Instruction manual Installation manual
Safety net M4x12 tapped Screw

E-5
Deciding on Where to Install the Indoor Unit
Indoor Unit
 There must be no obstacles near the air inlet and outlet.
 Install the indoor unit on a ceiling that can support its weight.
 Maintain sufficient clearance around the indoor unit.
 Make sure that the water dripping from the drain hose runs away correctly and
safely.
 The indoor unit must be installed in this way, that they are out of public access.

Indoor Unit Installation
It is recommended to install the refnet joint before installing the indoor unit.
1
Place the pattern sheet on the ceiling at the spot where you want to install
the indoor unit.
Note  Since the diagram is made of paper, it may shrink or stretch
slightly due to temperature or humidity. For this reason,
before drilling the holes maintain the correct dimensions between
the markings; refer to page 6.
2
Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in figure.
3
Install the suspension bolts depending on the ceiling type.
IMPORTANT

Ensure that the ceiling is strong enough to support
the weight of the indoor unit. Before hanging the unit,
test the strength of each attached suspension bolt.
If the length of suspension bolt is more than 1.5m,
it is required to prevent vibration.
4
Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
IMPORTANT You must install the suspension bolts more than four
when installing the indoor unit.
5
Hang the indoor unit to the suspension bolts between two nuts.
Note Piping must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
piping into position for connection to the unit before placing the unit
inside the ceiling.
6
Screw the nuts to suspend the unit. Cut a pad stopper and place it on the
bracket at this time.
7
Adjust the unit to the appropriate position considering the installation area for the
front panel.
7-1 Place the pattern sheet on the indoor unit.
7-2 Adjust a space between the ceiling and the indoor unit by using the gauge
of dimensions.
7-3 Fix the indoor unit securely after adjusting level of the unit by using a leveler.
7-4 Remove the pattern sheet, connect the other cables and install the front panel.

Purging the Unit
Liquid refrigerant
port
Gas refrigerant port
On delivery, the indoor unit is loaded with Nitrogen gas.
All this gas must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result: All inert gas escapes from the indoor unit.
Note

To prevent dirt or foreign objects from getting into the pipes during
installation, do NOT remove the pinch pipe completely until you are ready
to connect the piping.

E-9
Connecting the Refrigerant Pipe
ENGLISH
There are two refrigerant pipes of differing diameters:

A smaller one for the liquid refrigerant

A larger one for the gas refrigerant

The inside of copper pipe must be clean & has no dust.
1Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque wrench,
a spanner applying the following torque.
Outer Diameter Torque (kgf•cm)
9.52 mm (3/8")
12.70 mm (1/2")
15.88 mm (5/8")
19.05 mm (3/4")
22.23 mm (7/8")
250~280
380~420
440~480
990~1210
990~1210
Note

If the pipes must be shortened refer to page 10.
2Must use insulator which is thick enough to cover the refrigerant pipe to
protect the condensate water on the outside of pipe falling onto the floor
and the efficiency of the unit will be better.
3Cut off any excess foam insulation.
4Be sure that there must be no crack or wave on the bended area.
5It would be necessary to double the insulation thickness (10mm or more)
to prevent condensation even on the insulator when if the installed area is
warm and humid.

Cutting/Flaring the Pipes

CAUTION
In case of welding the pipe, you must weld with nitrogen gas
blowing.
1
Make sure that you have the required tools available (pipe cutter, reamer,
flaring tool and pipe holder).
2If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure
that the cut edge remains at a 90° angle with the side of the pipe. Refer to the
illustrations below for examples of edges cut correctly and incorrectly.
Oblique Rough Burr
3
To prevent any gas from leaking out, remove all burrs at the cut edge of the
pipe, using a reamer.
4
Slide a flare nut on to the pipe and modify the flare.
