Then tighten the nut with a spanner and torque wrench as shown in the figure. CAUTION · Do not apply excess torque. Otherwise, the nut may crack depending on the installation conditions. Tightening touque N·m (kgf·m) 16 ~ 18 (1, 6 ~ 1, 8) 30 ~ 42 (3, 0 ~ 4, 2) 50 ~ 62 (5, 0 ~ 6, 2) Flare nut Outer dia. 6, 35mm 9, 52mm 12, 7mm Half union or packed valve Externally threaded side Use a wrench to secure. Internally threaded side Use a torque wrench to tighten. 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 for R22 Port size 7/16 UNF 20 threads per inch Manifold for R410A 1/2 UNF 20 threads per inch 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 VP B Liquid (Ø6, 35) Packed valve D AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using 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. (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). (7) Securely tighten the stem cap to each of the packed valve stems. Fig. 8-5-5 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. · Valve stem cap tightening torque is as follows; 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 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. (1 screw) (2) Connect the connecting cable to the terminals as identified with their respective matched numbers on the terminal block of indoor and outdoor units. (Strip the sheath of connecting cable with following stripping length to and insert into the terminal block. ) (3) When connect the connecting cable to outdoor unit terminal, make a loop as shown in the installation diagram of indoor and outdoor unit, to prevent water coming in the outdoor unit. (4) Insulate the unused cords (conductors) with water coming in the outdoor unit.
