Automatic Mode Operation

Standard for determining operation mode

First Determination:

Second Determination: One hour after the above determination, the unit will operate according to the table below.
1. Indoor fan operates at super low speed for 20 seconds. 2. After judging indoor air temperature, the operation is determined and operation continued at the mode determined. 3. If indoor temperature is less than 16C, heating operation will immediately operate. 4. After the operation mode has been determined, the mode does not change. However, Soft Dry mode operation induces cooling mode operation. 5. If automatic mode operation is started while the unit is operating, operation will continue. If current operation is in cooling mode (including the cooling mode operation when is a part of Soft Dry mode operation) it will be maintained, and if current operation is not cooling mode, the appropriate operation mode is determined for 20 seconds at super slow fan speed. Then the selected mode will continue. 6. Room temperature adjustment

Air purging (Installation)
The air in the indoor unit and in the piping must be purged. If air remains in the refrigeration pipings, it will affect the compressor, reduce the cooling capacity and could lead to a malfunction.
Required tools: hexagonal wrench, adjustable wrench, torque wrench, wrench to hold joints and gas leak detector. The additional gas for air purging has been charged in the outdoor unit. However, if the flare connections have not been done correctly and there are gas leaks, a gas cylinder and the charge set will be needed.
Service port cap Be sure using a torque wrench to tighten the service port cap (after using the service port), so that it prevents the gas leakage from the refrigerant cycle.
Procedure: 1. Recheck the piping connection. 2. Open the valve stem of the 2-way valve counter-clockwise, wait 10 seconds and then set it to close position Be sure to use a hexagonal wrench to operate the valve stem. 3. Check for gas leakage. Check the flare connections for gas leakage. 4. Purge the air from the system Set the 2-way valve to the open position and remove the cap from the 3-way valves service port. Using hexagonal wrench to press the valve core pin, discharge for 3 seconds and then wait for 1 minute Repeat this for 3 times. 5. Use torque wrench to tighten the service port cap to a torque of 1.8kg.m (18N.m) 6. Set the 3-way valve to the opened position. 7. Mount the valves stem nuts to the 3-way and 3-way valve. 8. Check for gas leakage At this time, especially check for the leakage from the 2way and 3-way valves stem nuts, and from the service port cap. Caution

If gas leakage is found in step (3) above, take the following measure. 1. If the gas leaks stop when the piping connections are tighten further, continue working from step (4). 2. If gas leaks does not stop when the connections are retighten, repair the location of the leak, discharge all of the gas through the service port, and then recharge with the specified amount of gas from a gas cylinder.

2 Pumping down

(For Re-installation)
Procedure 1. Confirm that both 2-way and 3-way valves are set to open positions. Remove the valve stem caps and confirm that the valve stems are in the open position. Be sure using a hexagonal wrench to operate the valve stems. 2. Operate the unit for 10-15 minutes. 3. Stop operation and wait for 3 minutes, then connect the charge set to the service port of the 3-way valves. Connect the charge hose with the push pin to the service port. 4. Air purging of the charge hose Open the low-pressure valve or the charge set slightly to air purge from the charge hose. 5. Set the 2-way valve to the close position. 6. Operate the air conditioner at the cooling cycle and stop it when the gauge indicates 2 kg/cm2G (0.1Mpa). If the unit cannot be operate at the cooling mode operation (weather is rather cool), press the pump down, switch on the indoor unit, so that the unit can be operated. 7. Immediately set 3-way valve to the closed position. Do this quick so that the gauge ends up indicating 3 to 5 kg/cm2G. (0.3 to 0.5 Mpa). 8. Disconnect the charge set, and mount the 2-way and 3-way valve stems nuts and service port cap. Use torque wrench to tighten the service port cap to a torque 1.8kg.m (18N.m). Be sure to check for gas leakage.

9.2.1.

2-1 Re-air purging
Procedure 1. Confirm that both 2-way and 3-way valves are set to the closed position. 2. Connect the charge set and a charging cylinder to the service port of the 3-way valve. 3. Air purging Open the valves on the charge set and charging cylinder, purge the air by loosening the flare nut on the 2-way valve approximately 45for 3 seconds, then close it for 1 minutes; repeat this 3 times. After purging the air, use a torque wrench tightenting the flare nut on the 2-way valve. 4. Check for gas leakage Check the flare connections for gas leakage. 5. Discharge the refrigerant Open the valve on the charging cylinder and discharge the refrigerant unit the gauge indicates 3 to 5 kg/cm2G (0.3 to 0.5 Mpa). 6. Disconnect the charge set and the charging cylinder, and set the 2-way and 3-way valves to the open position. Be sure to use a hexagonal wrench to operate the valve stems. 7. Mount the valve stem nuts and the service port cap. Be sure to use a torque wrench to tighten the service port cap to a torque 1.5kg.m (18N.m). Be sure to check for gas leakage.

9.2.2.

2-2 Balance refrigerant of the 2-way, 3-way valves

(Gas leakage)

Procedure 1. Confirm that both 2-way and 3-way valves are set to the open position. 2. Connect the charge set to the service port of the 3-way valve. Leave the valve on the charge set closed. Connect the charge hose with the push pin to the service port. 3. Open the valves (low side) on the charge set and discharge the refrigerant until the gauge indicates 0.5-1 kg/cm2G (0.050.1Mpa). If there is no air in the refrigerant cycle [the pressure when the air conditioner is not running is higher than 1kg/cm2G (0.1Mpa)], discharge the refrigerant until the gauge indicates 0.5 to 1 kg/cm2G (0.05 to 0.1Mpa). If this is the case, it will not be necessary to apply a evacuation. Discharge the refrigerant gradually, if it is discharged too suddenly, the refrigerant oil will also be discharged.
Evacuation (Installation)
(No refrigerant in the refrigeration cycle)
Procedure 1. Connect the vacuum pump to the charge sets centre hose. 2. Evacuation for approximately 1 hour. Confirm that the gauge needle has moved toward-76cmHg (-0.1Mpa) [vacuum of 4 mmHg or less]. 3. Close the valve (low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle dose not move (approximately 5 minutes after turning off the vacuum pump). 4. Disconnect the charge hose from the vacuum. Vacuum oil If the vacuum pump oil becomes dirty or depleted, replenish as needed.

9.3.1.

Gas charging

(After evacuation)

Procedure 1. Connect the charge hose to the charging cylinder Connect the charge hose which was disconnected from the vacuum pump to the valve at the bottom of the cylinder. If you are using a gas cylinder also use a scale and reverse the cylinder so that the system can be charged with liquid. 2. Purge the air from the charge hose Open the valve at the bottom of the cylinder and use a screwdriver to press the check valve on the charge set to purge the air. (Be careful of the liquid refrigerant.) The procedure is the same if using a gas cylinder. 3. Open the valve (low side) on the charge set and charge the system with liquid refrigerant. If the system cannot be charged with the specified amount of refrigerant, it can be charge with a little at a time (approximately 150g each time) while operating the air conditioner in the cooling cycle. However, one time is not sufficient, wait approximately 1 minute and then repeat the procedure. (Pumping down pin)

This is different from previous procedures. Because you are charging with liquid refrigerant from the gas side, absolutely do not attempt to charge with large amounts of liquid refrigerant while operating the air conditioner.
4. Immediately disconnect the charge hose from the 3-way valves service port. Stopping part-way will allow the refrigerant to be discharged. If the system has been charged with liquid refrigerant while operating the air conditioner, turn off the air conditioner before disconnecting the hose. 5. Mount the valve stem nuts and the service port. Use a torque wrench to tighten the service port cap to a torque of 1.8kg. m (18N.m). Be sure to check for gas leakage.
