[. . . ] Using the hexagonal wrench to press the valve core pin, discharge for three seconds and then wait for one minute. Use torque wrench to tighten the service port cap to a torque of 1. 8 kgf. m. Set the 3-way valve to the opened position. 7. Mounted the valve stem nuts to the 2-way and 3-way valves. 8. At this time, especially check for gas leakage from the 2-way and 3-way stem nuts, and from the service port. Caution: If gas leakage is discovered in step (3) above, take the following measures. If the leaks stop when the piping connections are tightened further, continue working from step (4). If the gas leaks do not stop when the connections are retightened, 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. 14 7. 5 Pumping down (Re-installation) Procedure 1. Confirm that both the 2-way and 3-way valves are set to the opened position. Remove the valve stem caps and confirm that the valve stems are in the opened position. Be sure to use a hexagonal wrench to operate the valve stems. Stop operation and wait for 3 minutes, then connect the charge set to the service port of the 3-way valve. Confirm that both the 2-way and 3-way valves are set to the open position. Connect the charge set to the 3-way valve's service port. Leave the valve on the charge set closed. Connect the charge hose with the push pin to the service port. Open the valves (Low side) on the charge set and discharge the refrigerant until the gauge indicates 0. 05 to 0. 1Mpa. If there is no air in the refrigeration cycle [the pressure when the air conditioner is not running is higher than 0. 1Mpa, discharge the refrigerant until the gauge indicates 0. 05 to 0. 1 Mpa. If this is the case, it will not be necessary to apply an evacuation. Discharge the refrigeration gradually; if it is discharged too suddenly, the refrigeration oil sill be discharged. 17 7. 8 Evacuation Procedure: 1. Connect the vacuum pump to the charge set's centre hose. Confirm that the gauge needle has moved toward -0. 1 Mpa (-76 cmHg) [vacuum of 4 mmHg or less]. Close the valve (Low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump). [. . . ] No The power supply for outdoor PCB is fail. Check the wiring on outdoor PCB comparing with wiring plate. Is the failure cleared? NO Reconnect and retest again Yes 10. 3. 3 E2(zero-crossing signal error) diagnosis and solution Is power supply and connection of connectors good?NO Be sure the power supply is good and correct the connection 36 10. 3. 4 E3(indoor fan speed out of control) diagnosis and solution Is the indoor fan motor connector and connection good?
