13-4-2.Connect the vacuum pump and a manifold valve as shown Fig. 1. Confirm that all connections are cor- rectly made.

NOTE

In order to withstand negative suction pressure during evacuation, the manifold valve should be equipped with a Hi/Lo compound gauge with a minimum scale reading of –76 cmHg.

13-4-3.Install (first by hand-tightening, then securely with a wrench) flare nuts and bonnets at service valves in the refrigeration circuit where evacuation will take place. This process is highly important to completely evacuate the system.

13-4-4.Check that the BLK/WHT connector is properly attached. (Fig. 1)

13-4-5.Turn the disconnect switch ON (if it has been OFF) to open the 2 solenoid valves (SV1 and SV2). (Fig. 2)

13-4-6.With both the “Lo” and “Hi” knobs of the manifold valve open, run the vacuum pump. The operation time varies with the capacity of the pump. (Run the pump at least 30 minutes.) Evacuation is successful if

the vacuum gauge reading remains at –75 cmHg or more for at least 10 seconds after closing both the “Lo” and “Hi” knobs of the manifold valve.

13-4-7.With the vacuum pump still running, turn both the narrow and wide service valves all the way in to close the valves (position – b – in Fig. 3). Then stop the pump.

13-4-8.After removing the vacuum hoses from the service valves, replace the flare nuts and bonnets on the valves. The refrigerant circuit is now ready for charging.

13-5. Refrigerant Charging

13-5-1.After evacuation is completed, charge the circuit with the proper amount of refrigerant.

NOTE

The proper amount of refrigerant is specified on the nameplate of the outdoor unit and in Section “2-1. Unit Specifications” in the service manual.

13-5-2.Use a hose to connect the narrow tube service valve to the liquid port of the charging cylinder. (Fig. 4)

13-5-3.Purge air from the hose. Do this by opening the charging cylinder valve, then slightly loosening the connection to the narrow tube service valve. Wait a few moments, then retighten the connection.

13-5-4.With a hex wrench, open the service valve little by little to let liquid refrigerant enter the circuit. (Fig. 4)

NOTE

Write down the gradation levels on the charging cylinder before and after the charging. This allows you to calculate the charging volume.
