Caution Statements
1.We recommend that this air conditioner be installed properly by
WARNING
qualified installation technicians in accordance with the installation
instructions provided with the unit.
2.Before installation, check if the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
WARNING
Avoid:
3.Do not install the air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.
4.Do not install the air conditioner where excessively high heat generating objects are placed.
To protect the air conditioner from heavy corrosion, avoid installing the outdoor
unit where salty sea water can splash directly onto it or in sulphurous air near a
spa.
1.All wiring must conform to the local electrical codes.
2.Each unit must be properly grounded.
3.Wiring must be done by a qualified electrician.
4.Consider the capacity of the electric current of your electrical kilowatt hour meter wires and socket before installation.
5.Power for this air-conditioner is supplied by individual electrical wire.
6.There must be at least one ventilation intake in the area where the
heat-pump is mounted.
WARNING
CAUTION
1.Read this manual carefully before using this air conditioner. If you still have
any diffculties or problems, consult your dealer for help.
2.The air conditioner is designed to give you comfortable room conditions.
Use this only for its intended purpose as described in this instruction
manual.
3.Never use store gasoline or other flammable vapor or liquid near
t h e
air conditioner - it is very dangerous.
4.The air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you
use gas or oil heating appliances in the same room, which consume
a lot of oxygen from the air. Otherwise there is a risk of
s u f f o c a t i o n
1.Do not turn the air conditioner on and off from the power mains
switch. Use the ON/OFF operation button.
2.Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.
3.Do not let the children play with the air conditioner.
4.Do not cool or heat the room too much if babies or invailds are
present.

!
CAUTION
2. Vertical
The horizontal airflow can be adjusted by moving the vertical vanes with your hands to the
left or right.
When the humidity is high, the vertical vanes should be in the front
position during the cooling or dehumidifying operation. If the vertical
vanes are positioned all of the way to the right or left, condensation may
begin to form around the air vent and drip down.
The vertical airflow can be adjusted by moving the flap with the remote control unit
Do not move the flap with your hands.Confirm that the remote control unit has been
turned on. Then, use the FLAP button to set either the sweep function or one of

Special Remarks
A.In Cooling and DRY Mode:
When the night setback mode is selected, the air
conditioner automatically raises the temperature,
setting 1℃ when 60 minutes have passed, after the
selection was made ,and then another 1℃ after another 60
minutes have passed and at last stops operating
automatically after lasting about 6 hours at this
temperature, regardless of the indoor temperature when
night setback was selected. This enables you to save energy
without sacrificing comfort. This function is
convenient when gentle cooling is needed.

Care and Cleaning
!
!
WARNING
CAUTION
1.For safety, be sure to turn the air conditioner off and also to disconnect
the power before cleaning.
2.Do not pour water on the indoor unit to clean it. This will damage the
internal components and cause an electric shock hazard.
Clean the casing and grille of the indoor unit with a vacuum cleaner brush, or
wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid
deteraent. When cleaning the grille, be careful not to force the vanes out of
place.
1.Never use solvents, or harsh chemicals when cleaning the indoor unit.
Do not wipe the plastic casing using very hot water.
2.Some metal edges and the fins are sharp and may cause injury if
handled improperly; be especially careful when you clean these parts.
3.The internal coil and other components of the outdoor unit must be
cleaned every year.Consult your dealer or service center.

Let sunlight directly into the room. Use sunshades, blinds or curtains.
If the walls and ceiling of the room are warmed by the sun, it will take
longer time to cool the room.
●Always try to keep the air filter clean. (Refer to“Care and Cleaning” A
clogged filter will impair the performance of the unit.
●
To prevent conditioned air from escaping, keep windows, doors and any
other openings closed.

5.Air purging
Air and moisture remaining in the refrigerant system have undesirable
effects as indicated below. Therefore, they must be purged completely.
·pressure in the system rises
·operating current rises
·cooling efficiency drops
·moisture in the air may freeze and block capillary tubing
·water may lead to corrosion of parts in the refrigerant system
5-1.Air Purging with a Vacuum Pump (for Test Run)
(1)Check that each tube (both narrow and wide tubes between the indoor
and outdoor units have been properly connected and all wiring for the
test run has been completed. Note that both narrow and wide tube
service valves on the outdoor unit are kept closed at this stage.
(2)Using an adjustable wrench or box wrench, remove the valve caps from
the service valve on both narrow and wide tubes.
(3) Connect a vacuum pump and a manifold valve (with pressure gauges) to
the service port on the wide tube service valve.(Fig.A)
Be sur e to use a m anif o ld va l ve fo r a ir pur ging .
CAUTION
I f i t i s n o t a vail able , u se a s top val v e f or

(4)With the “Lo”knob of the manifold valve open, run the vacuum pump.
The operation time for the vacuum pump varies with tubing length and
the capacity of the pump. The following table shows the amount of time
Table
Required time for evacuation when capacity
of 100 liter/h vacuum pump is used
If tubing length is less than 10 m
10 min. or more
If tubing length is more than 10 m
15 min. or more
NOTENOTE
The required time in the above table is calculated based on the
assumption that the ideal (or target) vacuum condition is around 10
mmHg abs.
(5) With the vacuum pump still running, close the “Lo”knob of the
manifold valve. Then stop the vacuum pump.
(6)With the accessory hex wrench, turn the valve stem on the narrow
tube service valve counterclockwise by 90 degrees (1/4 turn) for
10 seconds, and then turn the stem clockwise to close it again.
(Fig.B)
Be sure to completely insert the hex wrench
CAUTION
before attempting to turn the valve.

(7)Leak test all joints at the tubing (both indoor and outdoors) with liquid soap. Bubbles indicate a
leak. Be sure to wipe off the soap with a clean cloth.
(8)With the hex wrench, turn the wide tube service valve stem counter-clockwise to fully open the
valve.
(9)Turn the narrow tube service valve stem counter-clockwise to fully open the valve.
(10)Loosen the vacuum hose connected to the wide tube service port slightly to release the pressure.
Then, remove the hose.
(11)Replace the bonnet and flare nut on the wide tube service port and fasten the flare nut securely
with an adjustable wrench or box wrench. Next, mount the valve cap and tighten it with a torque
wrench (the cap needs to be tightened with the torque of 200kg-cm). This process is very important
to prevent gas from leaking from the system.
(12)Test run the air conditioner.
(13)While the air conditioner is running, apply liquid soap to check for any gas leaks around the
service valves or caps.
(14)If there is no leakage, stop the air conditioner.
(15)Wipe off the soap on the tubing.
This completes air purging with a vacuum pump and
the air conditioner is ready for actual operation.
