METHOD II: Us this method if the existing outdoor unit is not equipped with shut-off valves,or if the unit is not operational and you plan to use the existing HCFC-22 to flush the system. Remove all HCFC-22 refrigerant from the existing system.Check gauges after shutdown to confirm that the entire system is completely void of refrigerant. METHOD 2: Use this method if the existing outdoor unit is equipped with manual shut-off valves,and you plan to use new HCFC-22 refrigerant to flush the system. The following devices could prevent full System charge recovery into the outdoor unit: Outdoor unit's high or low-pressure switches(if applicable)when tripped can cycle the compressor OFF. • Compressor can stop pumping due to tripped internal pressure relief valve. • Compressor has internal vacuum protection that is designed to unload the scrolls(compressor stops pumping)when the pressure ratio meets a certain value or when the suction pressure is as high as 20 psig.(Compressor suction pressures should never be allowed to go into a vacuum. Prolonged operation at low suction pressures will result in overheating of the scrolls and permanent damage to the scroll tips,drive bearings and internal seals.) Once the compressor can not pump down to a lower pressure due to one of the above system conditions,shut off the vapor valve.Turn OFF the main power to unit and use a recovery machine to recover any refrigerant left in the indoor coil and line set. Perform the following task: A Start the existing HCFC-22 system in the cooling mode and dose the liquid line valve. B Use the compressor to pump as much of the existing HCFC-22 refrigerant into the outdoor unit until the outdoor system is full.Turn the outdoor unit main power OFF and use a recovery machine to remove the remaining refrigerant from the system. NOTE—It may be necessary to bypass the low pressure switches(if equipped)to ensure complete refrigerant evacuation. C When the low side system pressures reach 0 psig,dose the vapor line valve. D Check gauges after shutdown to confirm that the valves are not allowing refrigerant to flow back into the low side of the system.

MINIMUM 3/9°HOSE B Evacuate the line set and indoor unit to an absolute pressure of 23,000 microns(29.01 inches of mercury). NOTE—During the early stages of evacuation,it is desirable to close the manifold gauge valve at least once.A rapid rise in pressure indicates a relatively large leak.If this occurs,repeat the leak testing procedure. NOTE—The term absolute pressure means the total actual pressure within a given volume or system,above the absolute zero of pressure.Absolute pressure in a vacuum is equal to atmospheric pressure minus vacuum pressure. C When the absolute pressure reaches 23,000 microns(29.01 inches of mercury),perform the following: • Close manifold gauge valves • Close valve on vacuum pump • Turn off vacuum pump • Disconnect manifold gauge center port hose from vacuum pump • Attach manifold center port hose to a dry nitrogen cylinder with pressure regulator set to 150 psig(1034 kPa)and purge the hose. • Open manifold gauge valves to break the vacuum in the line set and indoor unit. • Gose manifold gauge valves. D Shut off the dry nitrogen cylinder and remove the manifold gauge hose from the cylinder.Open the manifold gauge valves to release the dry nitrogen from the line set and indoor unit E Reconnect the manifold gauge to the vacuum pump,turn the pump on,and continue to evacuate the line set and indoor unit until the absolute pressure does not rise above 500 microns(29.9 inches of mercury)within a 20-minute period after shutting off the vacuum pump and dosing the manifold gauge valves. F When the absolute pressure requirement above has been met,disconnect the manifold hose from the vacuum pump and connect it to an upright cylinder of HFC-41 OA refrigerant Open the manifold gauge valve 1 to 2 psig in order to release the vacuum in the line set and indoor unit.
