Before using your air conditioner, please read this instruction manual carefully and keep it for future reference.
This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for
commercial use by lay persons.
This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do
not play with the appliance.
SAFETY PRECAUTIONS
! WARNING ! CAUTION
•
Installation and maintenance should be performed by
qualified persons who are familiar with local code
and regulation, and experienced with this type of
appliance.
•
All field wiring must be installed in accordance with
the national wiring regulation.
Ensure that the rated voltage of the unit corresponds to
•
that of the name plate before commencing wiring work
according to the wiring diagram.
The unit must be GROUNDED to prevent possible
•
hazard due to insulation failure.
All electrical wiring must not touch the refrigerant
•
piping, or any moving parts of the fan motors.
Confirm that the unit has been switched OFF before
•
installing or servicing the unit.
Disconnect from the main power supply before servicing
•
the air conditioner unit.
DO NOT pull out the power cord when the power is
•
ON. This may cause serious electrical shocks which
may result in fire hazards.
Keep the indoor and outdoor units, power cable and
•
transmission wiring, at least 1m from TVs and radios,
to prevent distorted pictures and static. {Depending on
the type and source of the electrical waves, static may
be heard even when more than 1m away}.
Please take note of the following important points when
installing.
•
Do not install the unit where leakage of flammable
gas may occur.
If gas leaks and accumulates around the unit, it
may cause fire ignition.
•
Ensure that the drainage piping is connected properly.
If the drainage piping is not connected properly,
it may cause water leakage which will dampen
the furniture.
•
Do not overcharge the unit.
This unit is factory pre-charged. Overcharge
will cause over-current or damage to the
compressor.
•
Ensure that the unit’s panel is closed after service
or installation.
Unsecured panels will cause the unit to operate
noisily.
•
Sharp edges and coil surfaces are potential locations
which may cause injury hazards. Avoid from being
in contact with these places.
•
Before turning off the power supply, set the remote
controller’s ON/OFF switch to the “OFF” position
to prevent the nuisance tripping of the unit. If this is
not done, the unit’s fans will start turning automatically
when power resumes, posing a hazard to service
personnel or the user.
•
Do not install the units at or near doorway.
•
Do not operate any heating apparatus too close to the
air conditioner unit or use in room where mineral oil,
oil vapour or oil steam exist, this may cause plastic
part to melt or deform as a result of excessive heat or
chemical reaction.
•
When the unit is used in kitchen, keep flour away from
going into suction of the unit.
•
This unit is not suitable for factory used where cutting oil
mist or iron powder exist or voltage fluctuates greatly.
•
Do not install the units at area like hot spring or oil
refinery plant where sulphide gas exists.
•
Ensure the color of wires of the outdoor unit and
the terminal markings are same to the indoors
respectively.
•
IMPORTANT : DO NOT INSTALL OR USE THE
AIR CONDITIONER UNIT IN A LAUNDRY
ROOM.
•
Don’t use joined and twisted wires for incoming power
supply.
•
The equipment is not intended for use in a potentially
explosive atmosphere.

INSTALLATION OF THE INDOOR UNIT
Preliminary Site Survey
Be sure to read this manual before installing the air-conditioner indoor unit.
•
Voltage supply Á uctuation must not exceed +10% of rated voltage. Electricity supply lines must be independent of
welding transformers which can cause high supply Á uctuation.
•
Ensure that the location is convenient for wiring, piping and drainage.
•
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
•
Do not move the unit from packaging while moving, until it reaches the installation site. Use safe material or protection
plates when unpacking it or lifting it to avoid damage or scratches to the unit.

•
Ensure a location where:
a)
Drainage can be done easily.
b)
Convenient for wiring and piping.
c)
Which have enough space for installation and service work.
d)
Where no risk of Á ammable gas leakage.
e)
When free from any obstacles in path of cool air discharge and warm air return and must allow spreading of air
throughout the room (near the center of the room).
f)
Must be provided clearance for indoor unit from the wall and obstacles as shown in À gure below.
g)
The installation place must be strong enough to support a load 4 times the indoor unit weight to avoid amplifying
noise and vibration.
h)
The installation place (hanging ceiling surface) must be assuring levelness and the height in the ceiling is 350mm or
more.
i)
The indoor unit must be away from heat and steam sources (avoid installing it near an entrance).
Unit Installation
Measure and mark the position for the hanging rod.
•
Ceiling Opening Site = 890mm
Hanging Rod Site = 790mm
Unit size 820mm
Drill the hole for the angle nut on the ceiling and fix the
hanging rod.
The installation template is extended according to
•
temperature and humidity. Check on dimensions in use.
The dimensions of the installation template are the same
•
as those of the ceiling opening dimensions.
Before ceiling laminating work is completed, be sure to
•
fit the installation template to the indoor unit.

Drain Piping Work
Flexible Hose
Pipe Clamp
Avoid installing the drain pipe in upward gradient after
the drain connection.
•
Ensure the height of drain pipe from ceiling is 700mm or
less if it is necessary to increase the height of drain pipe
to prevent water leak.
Avoid installing the drain pipe in up and down slope to
•
prevent reversed water flow.
•
During the drain pipe connection, be careful not to exert
extra force on the drain connector at indoor unit.
•
The outside diameter of the drain connection at the
