Fig. Vacuum Pumping Pressure gage INFORMATION In order to prevent any other refrigerant from being charged accidentally, each port of the manifold has been changed in shape. Differences in Port Size between Conventional R22 and R410A Manifold valve High pressure side handle Low pressure side handle Charge hose (A) Outdoor unit Indoor unit Gas (Ø9, 52) C A Service port Charge hose (B) Lo Hi Manifold for R22 Port size 7/16 UNF 20 threads per inch Manifold for R410A 1/2 UNF 20 threads per inch D B Liquid (Ø6, 35) Packed valve VP Fig. 8-5-5 AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of vacuum pump. <Use of vacuum pump> (1) Connect the charge hose (A) from the manifold valve to the charge inlet of the gas side packed valve. (2) Connect the charge hose (B) to the port of vacuum pump. (3) Open fully the low pressure side handle of the manifold valve. (5) Close the low pressure side handle of manifold valve after vacuumizing and stop the vacuum pump. Continue vacuumizing more than 15 minutes and check the pressure gage indicates ­0, 1MPa (­76 cmHg). (6) Open the stems of packed valves A and B all the way. (7) Securely tighten the stem cap to each of the packed valve stems. CAUTION · KEEP IMPORTANT 4 POINTS FOR INSTALLATION (PIPING WORK) (1) Take away dust and moisture (Inside of the connecting pipes. ) (2) Tight connection (between pipes and unit) (3) Evacuate the air in the connecting pipes using VACUUM PUMP . (4) Check gas leak (connected points) <Packed Valve Handling Precautions> · Open the valve stem all the way out; so not try to open it beyond the stopper. · Securely tighten the valve stem cap with the wrench or like. · Valve stem cap tightening torque is as follows; Gas pipes side (Ø12, 7) : 49 ~ 62 N·m (5, 0 ~ 6, 2 kgf·m) Gas pipes side (Ø9, 52) : 30 ~ 42 N·m (3, 0 ~ 4, 2 kgf·m) Liquid pipe side (Ø6, 35) : 16 ~ 18 N·m (1, 6 ~ 1, 8 kgf·m) Service port cap : 9 ~ 10 N·m (0, 9 ~ 1, 0 kgf·m) <A5 mm hexagon wrench is required. > Flare nut Valve body Stopper Wrench m Service port Valve stem Service port cap Valve stem cap Note : Service port at Gas pipes valve only. Wiring Connection (1) Remove the electric parts cover from the outdoor unit.
