• While in compressor off, the indoor fan repeats low airflow speed and pause.
• While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidifica-
tion operation and 4-min compressor off repeat.
Compressor ON Temp. ➲ Setting Temp+0.5°C
Compressor OFF Temp. ➲ Setting Temp-0.5°C
• In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.
■ Heating Mode Operation
• When the intake air temp reaches +3°…above the setting temp, the compressor is turned off. When below
the setting temp, the compressor is turned on.
Compressor ON Temp. ➲ Setting Temp.
Compressor OFF Temp. ➲ Setting Temp.+3°C
• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C, when above 28°C,it
operates with the low or setting airflow speed. When the indoor pipe temp is between 20°C and 28°C, it operates with Super-Low(while in sleep mode, with the medium airflow speed).
• While in compressor off, the indoor fan is off when the indoor pipe temp is below 33°C, when above 35°C,it
operates with the low airflow speed.
• If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, the
outdoor fan is turned on/off according to the indoor pipe temp.
• While in defrost control, both of the indoor and outdoor fans are turned off.
■ Defrost Control
• While in heating mode operation in order to protect the evaporator pipe of the outdoor unit from freezing,
reversed to cooling cycle to defrost the evaporator pipe of the outdoor unit.
• After 40 min heating mode operation, at 4 min interval, whether to carry out defrost control or not and the time
of defrost control are determined according to the following conditions.
1) While in heating mode operation, the maximum of the indoor pipe temperature is measured and it is com-
pared with the present indoor pipe temperature to get the difference of the indoor pipe temperatures (=the
maximum temperature of indoor pipe ? the present temperature of indoor pipe), according to which, whether
to carry out defrost control or not is determined.
2) According to the need of defrost control shown above and the elapsed time of heating mode operation at that
moment, the defrost control time is determined.
3) When the determined time of defrost control is below 7 min, heating mode operation continues without carry-
ing out defrost control. According to the procedure stated above, the determination is made again. When the
defrost control time is 7 min or longer, defrost control is then carried out.
• While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the present
temp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of the
indoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost control is completed and heating mode operation is carried out.
• While in defrost control, if the defrost time determined before the start of defrost control is completed, defrost
control stops and heating mode operation is carried out regardless of the above condition.
• When the indoor pipe temp is 42°C or above, defrost control is not carried out even if the condition is one of
the defrost conditions above.
• While in defrost control, the compressor is on and the indoor fan, the outdoor fan, and the 4 way valve are off.

■ Fuzzy Operation (C/O Model)
• According to the temperature set by Fuzzy rule, when the intake air temp is 0.5°C or more below the setting
temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.
Compressor ON Temp ➲ Setting Temp + 0.5°C
Compressor OFF Temp ➲ Setting Temp + 0.5°C
• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the
intake air temp at that time.
26°C ≤ Intake Air Temp ➲ 25°C
24°C ≤ Intake Air Temp< 26°C ➲ Intake Air Temp + 1°C
22°C ≤ Intake Air Temp< 24°C ➲ Intake Air Temp + 0.5°C
18°C ≤ Intake Air Temp< 22°C ➲ Intake Air Temp
Intake Air Temp<18°C ➲ 18°C
• When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the
Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature
automatically according to the Fuzzy rule.
• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the
temperature.
■ Fuzzy Operation (H/P Model)
• When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since
the operation off, the operation mode is selected.
• When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only
the indoor fan is operated for 15 seconds. Then an operation mode is selected according to the intake air
temp at that moment as follows.
24°C ≤ Inatake Air Temp ➲ Fuzzy Operation for Cooling

3) How to fix installation plate
The wall you select should be strong and solid enough
to prevent vibration
1. Mount the installation plate on the wall with four
type A screws. If mounting the unit on a concrete
wall, use anchor bolts.
• Mount the installation plate horizontally by aligning
thecenterlineusingalevel.
2. Measure the wall and mark the centerline. It is
also important to use caution concerning the
location of the installation plate-routing of the
wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping
connections must be done safely.
4) Drill a hole in the wall
• Drill the piping hole with a ø70mm hole core drill. Drill
the piping hole at either the right or the left with the
hole slightly slanted to the outdoor side.

2. Flaring Work and Connection of Piping
1) Flaring work
Main cause for refrigerant leakage is due to defect in
the flaring work. Carry out correct flaring work using the
following procedure.
1. Cut the pipes and the cable.
•
Use the piping kit accessory or pipes purchased locally.
• Measure the distance between the indoor and the
outdoor unit.
• Cut the pipes a little longer than the measured
distance.
• Cut the cable 1.5m longer than the pipe length.
2. Burr removal
• Completely remove all burrs from the cut cross section of pipe/tube.
• Put the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid dropping burrs into the tubing.
3. Putting nut on
• Remove flare nuts attached to indoor and outdoor
unit, then put them on pipe/tube having completed
burr removal.
(not possible to put them on after flaring work)
4. Flaring work
• Firmly hold copper pipe in a die in the dimension
showninthetableabove.
• Carry out flaring work using flaring tool as shown
below.
5. Check
• Compare the flared work with figure below.
• If flare is noted to be defective, cut off the flared sec-
tion and re-flare it.
