▶ Set the indoor unit address and installation option with remote controller option.
Set the each option separately since you cannot set the ADDRESS setting and indoor unit installation setting option at the
same time.You need to set twice when setting indoor unit address and installation option.
▶ Please use the proper wireless remocon which can set 24 digit option code. Following is the instructions of setting option
code with wireless remocon of MR-DH00. (MR-AH01 can be used for operating but cannot be used for setting the installation
option because only 12 digit option setting is available.
▶ Please refer to the wired remocon installation manual for setting with the wired remocon.

4-4 Items to be checked first
1.
The input voltage should be rating voltage ±10% range.
The air conditioner may not operate properly if the voltage is out of this range.
2.
Is the link cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 4 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the air conditioner may not operate properly.
3.
When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the
air conditioner.
No
Operation of air conditioner
Explanation
1
In a COOL operation mode, the compressor does not
operate at a room temperature higher than the setting
temperature that the INDOOR FAN should operate.
[In case of heat pump model]
In a HEAT operation mode, the compressor does not
operate at a room temperature lower than the setting
temperature that indoor fan should operate.
2
Compressor stops operation intermittently in DRY(
mode.
3
[In case of heat pump model]
Compressor of the outdoor unit is operating although it is
turned off in a HEAT mode.
When the unit is turned off while de-ice is activated, the
compressor continues operation for up to 12 minutes(maximum)
until the deice is completed.
4
[In case of heat pump model]
The compressor and indoor fan stop intermittently in HEAT
mode.
The compressor and indoor fan stop intermittently if room
temperature exceeds a setting temperature in order to protect
the compressor from overheated air in a HEAT mode.
5
[In case of heat pump model]
Indoor fan and outdoor fan stop operation intermittently
in a HEAT mode.
The compressor operates in a reverse cycle to remove
exterior ice in a HEAT mode, and indoor fan and outdoor
fan do not operate intermittently for within 20% of the total
heater operation
4-24
)
In happens after a delay of 3 minutes when the compressor is
reoperated. The same phenomenon occurs when a power is on.
As a phenomenon that the compressor is reoperated after a
delay of 3 minutes, the indoor fan is adjusted automatically with
reference to a temperature of the air blew.
Compressor operation is controlled automatically in DRY mode
depending on the room temperature and humidity.

4-6 PCB Inspection Method
4-6-1 Pre-inspection Notices
1. Turn off the breaker, AC power source, before disassembling the unit because of electrical hazard.
2. Confirm the complete discharge of capacitor C102, C702, C703, C704, C705, C706, C707 on the INVERTER PCB when you touch the
PCB.Especially dischargeing speed of C702-C707 is very slow because of little load in stand-by condition. To confirm the voltae of
C702-C707, measure the DC link voltage at the IGBT module pins near C701 at which applying voltage(450-510Vdc) is marked.
To confirm discharging of C102, measure the voltage of non mounted C103 solder hole or check if all LEDs are off.
3. Don’t touch the metal body of electrolytic capacitor for avoiding electrical shock before confirming discharge.
4. To discharging the capacitor use power resistor of about 1 Kohm 10W. Soldering tool(non electronic temperature control type) can
be used as a discharging resistor.
5. Don’t pull the lead wire but hold the whole housing to disconnect or connect a housing from or to the PCB.
4-6-2 Inspection Procedure
1. Check the connection of each housing to the connector first and the peeling of PCB copper pattern.
2. The PCB is composed of the 3 part in the indoor unit.

■ CONDENSER
High temperature and high pressure gas state coolant discharged from the compressor is converted to a liquid state as it
is cooled down by the heat emission in the outdoor condenser unit, and sent to the evaporator.
■ COMPRESSOR
Low temperature and low pressure coolant is compressed and sent to the cycling system
■ EVAPORATOR Liquid coolant sucked in through the capillary tubes cools down the room by absorbing the surrounding heat as it evaporates (converting from liquid to gas). (Absorbing heat required for evaporation)
■ SERVICE VALVE
You can open the valve by turning the need valve counterclockwise using hex wrench, and it is used for vacuum, gas
purging, coolant injection, coolant purging, and indoor-outdoor unit connection.
■ ACCUMULATOR
Accumulator prevents the flow of liquid-state coolant into the compressor. (Liquid-state coolant flowing into the compressor will overload the compressor.)
