Remote Control Operation Mode• When the remote control is selected by the slide switch on the main unit, the appliance operates according to
the input by the remote control.
Protection of the evaporator pipe from frosting• If the indoor pipe temp is below 0°C in 7 min. after the compressor operates without any pause while in cool-
ing cycle operation mode, the compressor and the outdoor fan are turned off in order to protect the indoorevaporator pipe from frosting.
• When the indoor pipe temp is 7°C or higher after 3 min. pause of the compressor, the compressor and theoutdoor fan is turned on according to the condition of the room temperature.
Buzzer Sounding Operation• When the appliance-operation key is input by the remote control, the short "beep-beep-" sounds.• When the appliance-pause key is input by the remote control, the long "beep—" sounds.• When a key is input by the remote control while the slide switch on the main unit of the appliance is on the
forced operation position, the error sound "beep-beep-beep-beep-beep-" is made 10 times to indicate that theremote control signal cannot be received.

• Procedure1. Confirm that both the gas side and liquid side
valves are set to the open position.- Remove the valve stem caps and confirm that
the valve stems are in the raised position.
- Be sure to use a hexagonal wrench to operatethe valve stems.
2. Operate the unit for 10 to 15 minutes.
3. Stop operation and wait for 3 minutes, then con-nect the manifold gauge to the service port ofthe gas side valve.- Connect the hose of the gauge with the push
pin to the service port.
4. Air purging of the charge hose.- Open the Low-handle valve on the gauge
slightly to air purge from the hose.
5. Set the liquid side valve to the closed position.
6. Operate the air conditioner at the cooling cycleand stop it when the gauge indicates 1kg/cm2g.
7. Immediately set the gas side valve to the closedposition.- Do this quickly so that the gauge ends up indi-
cating 1kg/ g.
8. Disconnect the charge set, and mount the liquidside and gas side valve caps and the serviceport nut.- Use torque wrench to tighten the service port
nut to a torque of 1.8kg.m.(4.2kg*m/5.5kg*m)
- Be sure to check for gas leakage.

2. Connect the vaccum pump to the center hose ofthe manifold gauge.
3. Connect the service port of the gas side valve tothe low side of the gauge.
4. Connect power supply to outdoor unit.5. Evacuation for approximately one hour.
- Confirm that the gauge needle has movedtoward-76 cmHg (vacuum of 4 mmHg or less).
6. Close the Low handle of the gauge turn off thevacuum pump, and confirm that the gauge nee-dle does not move(approximately 5 minutesafter turning off the vacuum pump).
7. Disconnect the charge hose from the vacuumpump.- Vacuum pump oil.
If the vacuum pump oil becomes dirty or deplet-ed,replenish as needed.
8. Mount the valve caps and the service port caps.

(3) Gas Charging(After Evacuation)
• Procedure1. Connect the gauge to the charging cylinder.
- Connect the charge hose which you disconnect-ed from the vacuum pump to the valve at thebottom of the cylinder.
- If you are using a gas cylinder, also use a scaleand reverse the cylinder so that the system canbe charged with liquid.
2. Purge the air from the charge hose.- Open the valve at the bottom of the cylinder and
press the check valve on the charge set to purgethe air. (Be careful of the liquid refrigerant). Theprocedure is the same if using a gas cylinder.
3. Open the low handle on the gauge and chargethe system with liquid refrigerant.- If the system can not be charged with the speci-
fied amount of refrigerant, it can be chargedwith a little at a time (approximately 150g eachtime) while operating the air conditioner in thecooling cycle; however, one time is not suffi-cient, wait approximately 1 minute and thenrepeat the procedure(pumping down-pin).
4. Immediately disconnect the charge hose fromthe gas side valve's service port.
- Stopping partway will allow the gas to be dis-charged.
- If the system has been charged with liquidrefrigerant while operating the air conditionerturn off the air conditioner before disconnectingthe hose.
5. Mount the valve stem nuts and the service portnut.- Use torque wrench to tighten the service port
nut to a torque of 1.8 kg.m.(4.2kg.m/5.5kg.m.)- Be sure to check for gas leakage.

Title Cause of error Check point & Normal condition
Check Point1. Unplug the sensor on Indoor unit PCB.
2. Estimate the resistance of each sensor.
3. If the resistance of the sensor is 10KΩ/ 5KΩ at 25°C, then sensor is normal.
4. If the resistance of the sensor is 0 KΩ or ∞, then sensor is abnormal. Change the sensor.
5. Plug the sensor on Indoor unit PCB and Power ON.
6. Estimate the voltage of each sensor.
7. If the voltage of the sensor is 2.5Vdc at 25°C, then sensor is normal.
8. If the resistance of the sensor is 0 or 5Vdc, then sensor is abnormal. Repair or Change the PCB.

Title Cause of error Check point & Normal condition
Check Point1. Check the input power AC380~450V. (Outdoor, Indoor unit)
2. Check the communication wires are correctly connected.
Adjust the connection of wire
Confirm the wire of “Live”, “Neutral”
3. Check the resistance between communication line and GND.(Normal : Over 2MΩ)
4. Check the connector for communication is correctlyconnected.
5. Check the connection of GND1, GND2, and main GND.
6. If one indoor unit is operated normally, outdoor PCB is noproblem.
Check the another indoor unit.
