When choosing the tightening torque, comply with values designated by manufacturers. Table 6-2-7 shows reference values. b) Correctly align the processed flare surface with the union axis.
FILE NO. SVM-06012 6-3. Tools 6-3-1. Required tools The service port diameter of packed valve of the outdoor unit in the air conditioner using R410A is changed to prevent mixing of other refrigerant. To reinforce the pressure-resisting strength, flare processing dimensions and opposite side dimension of flare nut (For ∅12.70 copper pipe) of the refrigerant piping are lengthened.
FILE NO. SVM-06012 6-4. Recharging of Refrigerant When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the following steps. Recover the refrigerant, and check no refrigerant remains in the equipment. When the compound gauge’s pointer has indicated -0.1 Mpa (-76 cmHg), place the handle Low in the fully closed position, and turn off the vacuum pump’s power switch. Connect the charge hose to packed valve service port at the outdoor unit’s gas side.
FILE NO. SVM-06012 1 Be sure to make setting so that liquid can be charged. 2 When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down. It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant. Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the cylinder upside down if cylinder is not equipped with siphon.
FILE NO. SVM-06012 (2) Characteristics required for flux • Activated temperature of flux coincides with the brazing temperature. • Due to a wide effective temperature range, flux is hard to carbonize. • It is easy to remove slag after brazing. • The corrosive action to the treated metal and brazing filler is minimum. • It excels in coating performance and is harmless to the human body.

Air volume control (1) Distinction of outdoor units When the power supply is reset, the outdoors are distinguished, and control is exchanged according to the distinguished result. (1) Operation with [HIGH (H)], [MED (M)], [LOW (L)], or [AUTO] mode is performed by the command from the remote control. (2) Setting of the indoor fan speed Based on EEPROM data, rspeed of the indoor fan is selected.

Preset temp. °C 0 −0.5 −1 −1.5 −2 In heating operation, the indoor heat exchanger restricts revolving speed of the fan motor to prevent a cold draft. The upper limit of the revolving speed is shown in Fig. 8-4-1 and Table 8-4-1. L *1 *2 −5.0 −5.5 [FAN AUTO] Fig.
FILE NO. SVM-06012 8-5. Freeze preventive control (Low temperature release) 8-7. Louver control The cooling operation (including Dry operation) is performed as follows based on the detected temperature of Tc sensor or Tcj sensor. When [J] zone is detected for T1 minutes (Following figure), the commanded frequency is decreased from the real operation frequency. After then the commanded frequency changes every 2 minutes while operation is performed in [J] zone.
FILE NO. SVM-06012 8-9. Auto Restart Function 8-9-1. How to set auto restart function The indoor unit is equipped with an automatic restarting function which allows the unit to restart operating with the set operating conditions in the event of power supply being accidentally shut down. The operation will resume without warning three minutes after power is restored. This function is not set to work when shipped from the factory. Therefore it is necessary to set it to work.
FILE NO. SVM-06012 8-9-2. How to cancel auto restart function To cancel auto restart function, proceed as follows: Repeat the setting prodedure: the unit receives the signal and beeps three times. The unit will be required to be turned on with the remote control after the main power supply is turned off. When the unit is on standby (Not operating) Operation Motions The unit is on standby. → Push [TEMPORARY] button for more than three seconds. The unit starts to operate.
