It is therefore necessary to firmly tighten the flare pipe connecting sections (which connect the indoor and outdoor units) up to the specified tightening torque. Incorrect connections may cause not only a gas leakage, but also damage to the refrigerant cycle.

Then tighten the nut with a spanner and torque wrench as shown in the figure. Mark line CAUTION · Do not apply excess torque. · Otherwise, the nut may crack depending on the conditions. Half union Fig. 8-5-5 Flare nut Externally threaded side Internally threaded side Use a wrench to secure. Use a torque wrench to tighten. Fig. 8-5-6 CAUTION · KEEP IMPORTANT 4 POINTS FOR 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) - 53 - FILE NO. Evacuating After the piping has been connected to the indoor unit, you can perform the air purge together at once. AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using a vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of the vacuum pump. <Using a vacuum pump> Be sure to use a vacuum pump with counter-flow prevention function so that inside oil of the pump does not flow backward into pipes of the air conditioner when the pump stops. Connect the charge hose from the manifold valve to the service port of the gas side packed valve. Connect the charge hose to the port of the vacuum pump. Open fully the low pressure side handle of the gauge manifold valve. Operate the vacuum pump to start evacuating. Perform evacuating for about 15 minutes if the piping length is 20 meters.
