Installing the unit
WARNING
IMPORTANT: When installing the unit, always remember
to connect first the refrigerant tubes, then the electrical
lines.
• Upon receipt, inspect the product to verify that
it has not been damaged during transport. If the
product appears damaged, DO NOT INSTALL it and
immediately report the damage to the carrier or
retailer (if the installer or the authorized technician
has collected the material from the retailer.)
• After completing the installation, always carry out a
functional test and provide the instructions on how to
operate the air conditioner to the user.
• Do not use the air conditioner in environments with
hazardous substances or close to equipment that
release free flames to avoid the occurrence of fires,
explosions or injuries.
• Our units should be installed in compliance with the
spaces shown in the installation manual, to ensure
accessibility from both sides and allow repairs
or maintenance operations to be carried out. The
unit’s components should be accessible and easy to
disassemble without endangering people and objects.
• For this reason, when provisions of the installation
manual are not complied with, the cost required to
access and repair the units (in SAFETY CONDITIONS,
as set out in prevailing regulations) with harnesses,
ladders, scaffolding or any other elevation system
will NOT be considered part of the warranty and will
be charged to the end customer.

Step 1 Choosing the installation
location
Installation location requirements
• Do not place the outdoor unit on its side or upside
down. Failing to do so may cause the compressor
lubrication oil to run into the cooling circuit and lead
to a serious damage to the unit.
• Install the unit in a well-ventilated location away
from direct sunlight or strong winds.
• Install the unit in a location that would not obstruct
any passageways or thoroughfares.
• Install the unit in a location that would not
inconvenience or disturb your neighbors, as they
could be affected by the noise or the airflow coming
from the unit.
• Install the unit in a location where the pipes and the
cables can be easily connected to the indoor unit.
• Install the unit on a flat, stable surface that can
withstand the weight of the unit. Otherwise, the unit
can generate noise and vibration during operation.
• Install the unit so that the air flow is directed towards
the open area.
• Maintain sufficient clearance around the outdoor unit,
especially from a radio, computer, stereo system, etc.
CAUTION
• You have just purchased a system air conditioner
and it has been installed by your installation
specialist.
• This device must be installed according to the
national electrical rules.
• If your outdoor unit exceeds a net weight of 60 kg,
do not install it on a suspended wall, but stand it
on a floor.
• When installing the outdoor unit at the seaside, make
sure that it is not directly exposed to sea breeze. If
you cannot find an adequate place free from direct
sea breeze, construct a protection wall or a protective
fence.
– Install the outdoor unit in a place (such as near
buildings etc.) where it can be prevented from sea
breeze. Failure to do so may cause a damage to
the outdoor unit.
• If you cannot avoid installing the outdoor unit at the
seaside, construct a protection wall around to block
the sea breeze.
• Construct a protection wall with a solid material such
as concrete to block the sea breeze. Make sure that
the height and the width of the wall are 1.5 times
larger than the size of the outdoor unit. Also, secure
a space larger than 700 mm between the protection
wall and the outdoor unit for exhausted air to
ventilate.
Installation Procedure
• Install the unit at a height where its base can be
firmly fixed in place.
• Make sure that the water dripping from the drain
hose runs away correctly and safely.
CAUTION
• Depending on the condition of power supply, unstable
power or voltage may cause malfunction of the parts
or control system. (At the ship or places using power
supply from electric generator...etc)

CAUTION
• The outdoor unit must be installed according to the
specified distances in order to permit accessibility
from each side, to guarantee correct operation,
maintenance, and repair of the unit.
The components of the outdoor unit must be
reachable and removable under safe conditions for
people and the unit.
Step 2 Fixing the outdoor unit in place
Install the outdoor unit on a rigid and stable base to
or more
prevent disturbance from any noise caused by vibration.
When installing the unit at a height or in a location
exposed to strong winds, fix the unit securely to a
support (i.e., a wall or a ground).
Fix the outdoor unit with anchor bolts. Make sure that
the anchor bolts are 20 mm or higher from the base
surface.
Installation Procedure
Moving the outdoor unit with wire rope
1 Before carrying the outdoor unit, fasten two wire
ropes of 8 m or longer, as shown in the figure.
2 To prevent damages or scratches effectively, insert
a piece of cloth between the outdoor unit and the
ropes.
3 Move the outdoor unit.
CAUTION

• For information about the power cable
specifications for indoor and outdoor units, refer
to the installation manual.
• After peeling off the tube wire, you must insert a
contraction tube.
3 Insert both sides of core wire of the power cable into
the connection sleeve.
• Method 1: Push the core wire into the sleeve from
both sides.
• Method 2: Twist the wire cores together and push
it into the sleeve.
Step 4 Optional: Extending the power
cable

flip it over and compress another two points in the
same location.
• The compression dimension should be 8.0.
• After compressing it, pull both sides of the wire to
make sure it is firmly pressed.
5 Wrap it with the insulation tape twice or more and
position your contraction tube in the middle of the
insulation tape.
A total of three or more layers of insulation is
required.
7 After tube contraction work is completed, wrap it with
the insulation tape to finish.
CAUTION
• Make sure that the connection parts are not exposed
to outside.
• Be sure to use insulation tape and a contraction tube
made of approved reinforced insulating materials that
have the same level of withstand voltage with the
power cable. (Comply with the local regulations on
extensions.)
Installation Procedure
WARNING
• In case of extending the electric wire, please DO NOT
use a round-shaped Pressing socket.
– Incomplete wire connections can cause electric
shock or a fire.
6 Apply heat to the contraction tube to contract it.
