Air Purging and Evacuation

Evacuation

1.Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit.

Confirm the "Lo" knob of the manifold valve is open. Then, run the vacuum pump.

The operation time for evacuation varies with tubing length and capacity of the pump.

[Each Room] The vacuum pump must be operated less than 0.8torr (0.015 psi) of the gage pressure.

2.When the desired vacuum is reached, close the "Lo" knob of the manifold valve and stop the vacuum pump.

Finishing the job

1.With a service valve wrench, turn the valve stem of liquid side valve counter-clockwise to fully open the valve.

2.Turn the valve stem of gas side valve counter-clockwise to fully open the valve.

3.Loosen the charge hose connected to the gas side service port slightly to release the pressure, then remove the hose.

4.Replace the flare nut and its bonnet on the gas side service port and fasten the flare nut securely with an adjustable wrench. This process is very important to prevent leakage from the system.

5.Replace the valve caps at both gas and liquid side service valves and fasten them tight.
