5.1 Flaring the tube
(1) Cut the tube with a tube cutter to the desired length
(30.50cm is recommended)
(2) Smooth the edge of the copper tube with a reamer or a
file. Hold the pipe vertically with one end downward
to make sure that no copper scraps fall into the
copper tube.
Figure 17a Figure
17b
(3) Put the tube flarer on the copper tube.
(4) Flare the copper tube ( Figure 18)
Figure 18
Note: The flared tube should have:
Smooth internal surface
Smooth edges
Consistent length of the tapered surface
5.2 Connection of the tubes
(1) The sealing tube must be used to prevent dust or
water from getting into the tube.
(2) Before connecting the tube, apply some refrigerant
oil on the surface of the flared tube and connections
to prevent air leakage.( Figure 19)
(3) Align the connecting tube and the flared tube, and
then turn the tapered nut to connect tightly.
(Figure 20)
(4) Fasten the nuts with a spanner.

5.3 Heat insulation of the refrigerant tube
All refrigerant tubes must be insulated heat with at
least 8mm thick insulation materials. (Figure 21)
5.4 Wrapping the tubes
(1) Tie the two refrigeration tubes (including
electrical wire if permitted as regulated), water
drainage hose with white tape.
(2) Wrap half of the tubes outside the room starting
from the end. (Figure 22)
(3) Fix the wrapped tubes on the wall in clips with a
space of 120cm.
Note: Do not tie the tubes too tight as this may reduce
heat insulation. Separate water drainage hose and
refrigeration tubes to prevent formation of water
droplets.
5.5 Ending of installation
After completion of wrapping and insulation, seal the
hole on the wall with a suitable sealant.
5.6 Discharge gas
Place appliance A and then B. Air purging method is as
follows:
(1) Turn down the nuts on the wide and narrow tubes.
(2) Loose the nut of the flared wide tube one complete
turn with a spanner.
(3) Turn counterclockwise to open the core of the valve
with a socket screw wrench. Some gas will come out
from under the nut of the flared end of the wide tube.
Tighten the nut 10 to 15 seconds later.
(4) Test for leakage at the tube connector with soapy
water or a meter. If there is no leakage, turn
counterclockwise to open the tube core of the valve
on the wide tube with a socket screw wrench.
(5) Tighten the nuts on the wide , narrow tube valves and
the valve cover.
Please contact the technical service for further
information.

WARNING
WARNING
WARNING
CAUTION
Do not install the air conditioner where there are fumes or flammable gases, or
in an extremely humid space such as a greenhouse.
Do not install the air conditioner where excessively high heat-generating
objects are placed.
All wiring must conform to the local electrical codes.
Each unit must be properly grounded.
Wiring must be done by a qualified electrician.
Consider the capacity of the electric current of your electrical kilowatt-hour
meter wires and socket before installation.
Power for this air-conditioner is supplied by individual electrical wire.
There must be at least one ventilation intake in the area where the outdoor unit
is mounted.
Never use store gasoline or other flammable vapor or liquid near the air
conditioner - it is very dangerous.
The air conditioner has no ventilator for intaking fresh air from outdoors. You
must open the doors or the 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 suffocation in an extreme case.
Do not turn the air conditioner on and off from the power mains switch. Use the
ON/OFF operation button.
Do not stick anything into the air outlet of the outdoor unit. This is dangerous
because the fan is rotating at high speed.
Do not let the children play with the remote control unit.
Do not cool or heat the room too much if babies or invalids are present.
1. Read this manual carefully before using this air conditioner. If you still have any difficulties 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

NOTE This air conditioner consists of an indoor unit and an outdoor unit. You can control the
air conditioner with the remote control unit.
Air from the room is drawn into this section and passes
through air filters which remove dust.
Conditioned air is blown out of the air conditioner through
the air outlet.
The wireless remote control unit controls power ON/OFF,
operation mode selection, temperature, fan speed, timer
setting, and air sweeping.
The indoor and outdoor units are connected by copper
tubes through which refrigerant gas flows.
The outdoor unit contains the compressor, fan motor, heat
exchanger coil, and other electrical components.
Moisture in the room condenses and drains off through this hose.

Adjusting the Fan Speed
1. Automatic
Simply set the FAN SPEED selector to the position.
A microcomputer in the air conditioner automatically controls the fan speed when the mode is selected. When the
air conditioner starts operating, the difference between the room temperature (RT) and the set temperature (T) is
detected by the microcomputer which then automatically switches the fan speed to the most suitable level.
Cooling mode:
When difference between room FAN SPEED
temperature and set temperature is
RT ≥ T+3℃ High
T+3℃ > RT ≥ T+1℃ Medium
RT Low
Mild drying mode:
When difference between room FAN SPEED
temperature and set temperature is
RT ≥ T+5℃ High
T+5℃ > RT ≥ T+3℃ Medium
RT Low
< T+1℃

2. Manual
If you want to adjust fan speed manually during operation, just set the FAN SPEED selector as desired.

Operation Guide
Adjusting the Airflow Direction
1. Horizontal The horizontal airflow can be adjusted by moving the vertical vanes wit your hands to the left or right.
2. Vertical
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 the six airflow direction
!
CAUTION
Use the FLAP button on the remote control to adjust the position of the flap. If you
move the flap by hand, the flap position according to the remote control and the
actual flap position may no longer match. If this happens, shut off the unit, wait
for the flap to close, and then turn on the unit again; the flap position will now
be normal again.
Do not have the flap pointed down during cooling operation. Condensation may begin
to form around the air vent and drip down.
!
CAUTION
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

In cooling operation, the setting temperature range is from 16 C to 30 C.
Indoor fan has none stop status, even if the compressor stops, the
indoor fan is still working.
In fan operation, the indoor fan speed is set by the remote control unit,
the compressor and outdoor fan do not work.
In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically after three minutes.
In cooling operation, some plastic parts may expand or shrink due to a
sudden temperature change. In this event, a clicking sound may occur. This
is normal, and the sound will soon disappear.
The remote control unit sends the temperature signal to the air
conditioner regularly at three-minute intervals. If the signal from the
remote control unit stops for more than ten minutes due to the loss of the
remote control unit or other trouble, the air conditioner will switch to
the temperature sensor which is built into the indoor unit and control the
room temperature. In these cases, the temperature around the remote
control unit may differ from the temperature detected at the air
conditioner's position.

Care and Cleaning
16
For safety, be sure to turn the air conditioner off and also to disconnect the
power before cleaning.
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
detergent. When cleaning the grille, be careful not to force the vanes out of place.
Never use solvents, or harsh chemicals when cleaning the indoor unit. Do not wipe
the plastic casing using very hot water.
Some metal edges and the fins are sharp and may cause injury if handled improperly;
be especially careful when you clean these parts.
The internal coil and other components of the outdoor unit must be cleaned every
year. Consult your dealer or service center.
