To prevent overload, the compressor will not start within 3 minutes after stop.
2 The compressor runs when the room temperature is higher than the set temperature.
The compressor stops when the room temperature is equal to or lower than the set temperature.
3 The compressor stops in check mode or during protective functions.
4 Coil frost prevention
To prevent indoor coil frost, the compressor will stop when the indoor coil thermistor (RT2) reads 1°C or below after the
compressor has been continuously operated for 16 minutes or more. The coil frost prevention is released under any of the
following conditions.
● The indoor coil thermistor rises to 10°C or above.
● The room temperature becomes equal to or lower than the set temperature.
● COOL mode is stopped or changed to another mode.
NOTE : By cutting the jumper wire JR02 on the indoor controller board, the temperature to start coil frost prevention
changes from 1°C to - 3°C

5 Coil frost protection
When the indoor coil temperature becomes - 15°C or below, coil frost protection will proceed as follows.
<Start condition>
After the compressor has been continuously operated for 3 minutes or more, and the indoor coil temperature has been 15°C or below for 3 minutes, the coil frost protection will start.
<Coil frost protection>
Compressor stops for 6 minutes, and then restarts.
If the start condition is satisfied again during the first 10 minutes of compressor operation, both the indoor and outdoor units
stop, and the remote controller displays this occurrence.
<Termination conditions>
Coil frost protection released when the start condition is not satisfied again during the allowance, or when the COOL mode
stops changes another mode.
(2)Indoor fan control
Indoor fan speed depends on the remote controller setting.
However, if an outdoor unit abnormality is detected, the indoor fan speed will be LOW, regardless of the remote controller
setting.
(3)Auto vane control
Auto vane position depends on the remote controller setting.
(4)Detecting abnormalities in the outdoor unit
After the compressor has been continuously operated for 3 minutes, if the difference between the indoor coil temperature
and the room temperature is out of RANGE C for 1 minute, the indoor fan speed will turn to LOW. Five minutes later, if the
difference is still out of RANGE C, the outdoor unit is functioning abnormally. Thus, the compressor will stop and the remote
controller will display this occurrence.
RANGE A : Indoor coil temperature is more than 5 degrees above room temperature.
RANGE B : Indoor coil temperature is within 5 degrees either way of room temperature.
RANGE C : Indoor coil temperature is more than 5 degrees below room temperature.
(5)AUTO VANE CONTROL
1 Frequency judgement
When the unit operates for the first time after the circuit breaker turned to ON, the frequency, 50Hz or 60Hz, is judged by
the horizontality sensing switch. If The frequency cannot be judged immediately for some reason, the sensing operation
continues for 3 minutes with the vane motor at ON.
If the frequency cannot be judged yet after 3-minute sensing, the vane motor turns to OFF. But the AIR DISCHARGE
DIRECTION display continues to be indicated.
2 During cooling operation
When the cooling operation starts, the vane is automatically set to the horizontal However, the desired direction among four
below-listed can be selected with the vane button on the remote controller.
a) 10°
b) 30° downward
c) 60° downward (PK-2.5, 3, 4FL(S)A) / 50° downward (PK-1.6, 2FLA)
d) 70° downward (PK-2.5, 3, 4FL(S)A) / 60° downward (PK-1.6, 2FLA)
10°
e) Automatic swing (only PK-2.5, 3, 4FL(S)A)
NOTE : 30° is available only when the fan speed is HIGH.
<AUTO RETURN>
When discharge 50°, 60° or 70° continues for 1 hour with the fan speed at LOW, the
discharge direction turns to the horizontal discharge automatically.
NOTE1 : After that, 50°, 60° or 70° is available by setting with the remote controller,
and it continues for 1 hour.
NOTE2 : If the discharge direction changes from 50°, 60° or 70° , the direction
returns to the horizontal discharge when 1 hour has passed since the discharge 60°
started.
NOTE3 : If the discharge direction changes from 50° or 60° (or 70° ) to the horizontal
discharge, the 1-hour timer to return the horizontal discharge is cancelled.
3 During the operation OFF, the auto vane is in the airflow shut-off position.
4 When the vane motor is out of order or the connector is badly connected, the
remote controller display of the remote controller does not change.

2-6 Emergency operation
When the remote controller or microprocessor malfunctions and no other trouble exists, emergency operation is available
by setting the dip switch on the controller board.
[Check items]
(1) Make sure the compressor and the fans are running normally.
(2) Locate the trouble with the self-diagnostic function.
If the self-diagnostic function indicates that the protection
device (such as coil frost protection) is functioning, the sources
must be removed before attempting emergency operation.
Emergency operation ON/OFF is activated not with the remote
controller but with the circuit breaker.
[Emergency operation produce]
(1)Cooling operation is available by setting the dip switch SW3
1and 2 ON and 3 OFF on the indoor controller board.
(2)To start emergency operation, turn the outdoor side circuit
breaker ON first, and then the indoor side circuit breaker ON.
(3)During emergency operation, the indooor fan runs on HIGH
speed, the compressor runs continuously, and the louver
stops.

2 JR02:Jumper wire for the temperature to start coil frost prevention
Cutting JR02 changes the temperature from +1°C to -3°C.
3 JR03:Jumper wire for set temperature adjustment in HEAT mode
In HEAT operation, heated air stagnates in the upper part of the room. The indoor unit installed in the upper part of
the room will detect the air temperature higher than the actual temperature in the living space. This difference is
about 4 degrees. Therefore, the temperature detected by the room temperature thermistor should be corrected 4
degrees down. The unit with JR04 attached will make this adjustment.
4 JR04:Jumper wire for the indoor fan speed during thermostat OFF in HEAT mode
Cutting JR04 Changes the speed from Extra-Low to Low.
5 JR05:Jumper wire for detecting abnormalities in the outdoor unit
Cutting JR05 makes this detection unavailable. (Occurrence of abnormality can not be detected.)

Connection methed
Note 1. How to connect refrigerant pipes.
Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures. As long as the
connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging. Remove the
blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor units are
made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 5m,an additional charge of refrigerant is needed.
Note 2. The following main parts are contained in the optional refrigerant piping kit.
Heat insulating cover, vinyl tapes, nipples, sleeve and flange (for wall hole),connecting cables.

2. Set the address number (from SW1-1 to
SW1-6) in the dip switch when a centralized
remote controller is being used.
The address is the control number of each
unit in the centralized control system.
As the address serves as a time-delay device
as well, sequential starts (all units are triggered collectively by one single ON instruction) must be set with different address numbers (greater than O) for each adapter.
