R410A ozone a new HFC layer is The working refrigerant which pressure of 1 6 times higher than conventional proper installation servicing is essential does this not new refrigerant damage the refrigerant is R22 thus which is designed to operate with R410A POE or PVE oil is used as lubricant for R410 A compressor is different compressor must be to moist During from the installation mineral or oil servicing used extr a for To R22 precaution mischarging the diameter As an than R22 If the servicing taken not to expose the R410A system too long air Residual POE or PVE oil in the piping and prevent and materials exclusively for exclusively R410A are for refrigerant manifold R410A units air it conditioner is essential to valve flare incurs tools higher choose R410A charging the torque pressure copper refrigerant be sure gas to leakage ventilate occurs fully If during the installation refrigerant comes into contact with fire a poisonous gas may occur When installing or removing an ah conditioner do allow ah or moisture to remain in the refrigerant cycle of the service pipes correctly components can absorb moisture from tire air tools hose pressure gauge gas leak detector wrench vacuum pump and refrigerant cylinder Never use refrigerant other than R41OA in an air conditioner which Use Tools port on the flare valve is different from that of R22 VACUUMING AND CHARGING Vacuuming is necessary to eliminate all moisture and ah from the system Vacuuming The Piping And The Indoor Unit Except for the outdoor unit which is pre charged with refrigerant the indoor unit and the refrigerant connection pipes must be air purged because the air containing moisture that remains in the refrigerant cycle may cause malfunction of the compressor Remove the caps from the valve and the service port Connect the center of the charging gauge to the vacuum pump Connect the charging gauge to tire service port of tire 3 way valve Start the vacuum pump Evacuate for approximately 30 minutes The evacuation time varies with different vacuum pump capacity Confirm that the charging gauge needle has LOW PRESSURE GAUGE HIGH PRESSURE GAUGE moved towards 760mmHg Caution If the gauge needle does not move to 760mmHg be sure to check for leakage at flare type connection of the indoor and outdoor unit and repair the leak before proceeding to the next step Close the valve of the changing gauge and stop the vacuum pump On the outdoor unit open the suction valve 3 way and liquid valve 2 way in anti clockwise direction with 4mm PURGE BY CHARGING key for hexagon sacked screw Charge Operation LOW PRESSURE GAUGE This operation must be done by using a gas cylinder and a precise weighing machine The additional charge is topped up into the outdoor unit using the suction valve via the service port Remove the service port cap Connect the low pressure side of the charging gauge to the suction service port center of the cylinder tank and close the high pressure side of the gauge Purge the air from the service hose Start the ah conditioner unit Open the gas cylinder and low pressure charging valve When the required refrigerant quantity is pumped into the unit close the low pressure side and the gas cylinder valve Disconnect the service hose from service port Put back the service port cap HIGH PRESSURE GAUGE PURGE BY CHARGING 1 13 gas not English SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT
