NOTE: The sound level is measured in an anechoic room where echoes are few, when compressor stops. The sound
may be bigger than displayed level under actual installation condition by surrounding echoes. The sound level
can be higher by about 2 dB than the displayed level during cooling and heating operation.
• Area in which the remote controller is not exposed direct sunshine.
• Area in which there is no nearby heating source.
• Area in which the remote controller is not exposed to cold (or hot) winds.
• Area in which the remote controller can be operated easily
• Area in which the remote controller is beyond the reach of children.
Installation method
1 Attach the remote controller holder to the desired location using two tapping screws.

Hexagonal

Connect the refrigerant pipes (both the liquid and gas
pipes) between the indoor and the outdoor units.
Remove the service port cap of the stop valve on the side of the outdoor unit gas pipe.
(The stop valve will not work in its initial state fresh out of the factory (totally closed with cap on).)
Connect the gauge manifold valve and the vacuum pump to the service port of the stop valve on the gas
pipe side of the outdoor unit.
Run the vacuum pump. (Vacuumize for more than 15 minutes.)
Check the vacuum with the gauge manifold valve, then close the gauge manifold valve, and stop the
vacuum pump.
Leave as it is for one or two minutes. Make sure the pointer of the gauge manifold valve remains in the
same position. Confirm that the pressure gauge show-0.1 MPa(-76 cmHg)
SU(H)-1VR
SU(H)-1.6VR2
SU(H)-2VR
Remove the gauge manifold valve quickly from the service port of the stop valve.
After refrigerant pipes are connected and evacuated, fully open all stop valves
on gas and liquid pipe sides.
Operating without fully opening lowers the performance and causes trouble.
Pipe length :
7m maximum
No gas charge is
needed.
Tighten the cap to the service port to obtain the initial status.
Retighten the cap.

DATA
The standard data contained in these specifications apply only to the operation of the air conditioner under normal condition.
Operating conditions vary according to the areas where these units are installed. The following information has been provided
to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.
(1) GUARANTEED VOLTAGE
Rated voltage : ±10% (198~264V), 50Hz
(2) AIR FLOW
Air flow should be set at MAX.
(3) MAIN READINGS
COOLING
(1) Indoor intake air wet-bulb temperature : W.B. ˚C
(2) Indoor outlet air wet-bulb temperature : W.B. ˚C
(3) Outdoor intake air dry-bulb temperature : D.B. ˚C
(4) Total input : W
Indoor air wet/dry-bulb temperature difference on the side of the chart on page shows the difference between the
indoor intake air wet/dry-bulb temperature and the indoor outlet air wet/dry-bulb temperature for your reference at service.
HEATING
(1) Indoor intake air dry-bulb temperature : D.B. ˚C
(2) Indoor outlet air dry-bulb temperature : D.B. ˚C
(3) Outdoor intake air wet-bulb temperature : W.B. ˚C
(4) Total input : W
How to measure the indoor air wet-bulb/dry-bulb temperature difference
1. Attach at least 2 sets of wet-and-dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of
wet-and-dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed
is high.
2. Attach at least 2 sets of wet-and-dry-bulb thermometers to the outdoor air inlet.
Cover the thermometers to prevent direct rays of the sun.
3. Check that the air filter is cleaned.
4. Open windows and doors of the room.
5. Press the TEST RUN switch once to start the COOL(HEAT) MODE.
6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.
7. 10 minutes later, measure temperature again and check that the temperature does not change.

1 Temperature control
When the indoor coil thermistor RT12 reads -1°C or below, the coil frost prevention mode starts immediately.
However the coil frost prevention will not work for 10 minutes after the compressor starts.
During the coil frost prevention compressor stops and the indoor fan operates at the set speed for 5 minutes.
After that, if RT12 still reads or below -1°C, this mode prolonged until the RT12 reads over -1°C.
After the coil frost prevention stops, units will not enter this mode again at least 10 minutes even RT12 reads -1°C.
2 Time control
When the three conditions below have been satisfied for 1 hour and 45 minutes, compressor stops for 3 minutes.
a. Compressor has been continuously operating.
b. Indoor fan speed is LOW / MED.
c. Room temperature is below 26°C.
When compressor stops ,the accumulated time is cancelled and when compressor restarts, time counting starts from
the beginning.
Time counting also stops temporarily when the indoor fan speed becomes HIGH or the room temperature exceeds 26°C.
However, when two of the above conditions (b. And c.) are satisfied again time accumulation is resumed.

The fan runs at set speed when the indoor coil thermistor RT12 temperature exceeds 22°C. The fan operates at VLo
when the temperature is below 18°C. But the fan stops when the indoor fan operates at VLo and the room temperature
is 15°C or less.Released
Cold Air Prevention
NOTE : At initial in hysteresis this control works.
2 New warm air control.
When compressor starts in heating operation or after defrosting, the fan changes the speed with dependence on the
indoor coil thermistor RT12 temperature to blow out warm air.
After releasing of cold air prevention, when the indoor coil temperature is 37°C or above, the fan speed shifts to the set
speed, and when the fan speed is changed by the remote controller, the fan speed is the set speed.
When the indoor coil temperature is less than 37°C, the fan speed is controlled by time as below.
<Time condition> <Indoor fan speed>
• Less than 2 minutes·······································LOW
• 2 minutes or more, less than 4 minutes ········MED.
• 4 minutes or more··········································HIGH
The upper limit of the fan speed is the set speed.
If the thermostat turns off, this operation changes to flow soft control.
3 Flow soft control
After the thermostat turns off, the indoor fan operates at VLo.
NOTE : When the thermostat turns on, the fan operates at the set speed. Due to the cold air prevention control, the fan
does not start until the indoor coil thermistor RT12 reads 22°C or more.

Emergency operation
switch(heating)
Operation lamp
Measure an impedance between the power supply terminal block on the outdoor unit and the ground with
a 500 V Megger and check that it is equal to or greater than 1.0MΩ.
• Before performing the test run, recheck for any wrong wiring.
Wrong wiring prevents normal operation or results in blown fuse disabling operation.
• The test run can be started by pressing emergency operation switch (cooling/heating). When the emergency operation
switch is once pressed, the unit will start the test run (continuous operation) for 30 minutes.
A thermostat does not work during this time. After 30 minutes the unit will start the emergency operation at a fixed temperature
setting of 24°C in cooling mode or heating mode.
Procedure
1 Press the button [Emergency operation switch(cooling)] to start the cooling operation.
If the [Operation lamp] blinks every 0.5 seconds, inspect the indoor/outdoor connecting wire for mis-wiring.
• Check that the vanes operate properly when cool air is blown out.
2 Press it once more, and the operation stops.
3 Press the button [Emergency operation switch(heating)] to start the heating operation. (SLH only)
Check that warm air blows out.
• In starting the heating operation, indoor unit fan may not operate to prevent blowing cool air. Please wait for a few minutes
unit the temperature of heat exchanger rises and warm air blows out.
4 Press it once more, and the operation stops. (SLH only)
Checking the remote (infrared) signal reception
Press the ON/OFF button on the remote controller and check that an electronic sound is heard from the indoor unit. Press the
ON/OFF button again to turn the air conditioner off.
If the indoor unit is operated with the remote controller, both the test run and the emergency operation are released
by commands from the remote controller.
Once the compressor stop, the restart preventive device operates so the compressor will not operate for three minutes to
protect the air conditioner.
