3.3 Recovering Refrigerant

Note: Refrigerant should not be exhausted to the atmosphere.

3.3.1 Ensure the blue low side hose is connected to the A/C system’s low side service port, the red high side hose is connected to the A/C

  system’shighsideserviceportandtheyellowcentrehoseconnectstotheinletoftherecoveryunit.Setupasing.1.

3.3.2 Follow the instructions provided with the recovery unit for proper recovery of refrigerant from the A/C system.

3.4 Evacuating and Charging a Refrigerant System

3.4.1 See section 3.1 (Connecting quick couplers) before proceeding. Connect the blue low side hose to the A/C system’s low side service port.

Connect the red high side hose to the A/C system’s high side service port.

3.4.2 Check the manifold gauge pressure reading to be sure the A/C system has been recovered properly. If not, follow steps under Section 3.3

3.4.5 Disconnect the yellow hose from the vacuum pump and connect it to the refrigerant supply.

3.4.8 When you have charged the system, close both manifold hand-wheels. Let the compressor run and check the manifold’s gauge pressure

readings to be sure the system is operating properly. If it is not, adjust the system as necessary. To disconnect the manifold when the

  systemisoperatingcorrectly,rstclosethehighsidecouplervalve,thendisconnecttheredhighquickcouplerfromtheA/Csystem.

3.4.9 Restart the A/C system, then open both manifold hand-wheels. Refrigerant from both hoses will be drawn quickly into the A/C system

through the blue low side hose.

3.4.10 When both gauges show the lowest operating pressure recommended by the manufacturer, close the low side valve and turn off the A/C

system.

3.4.11 Close the low side coupler valve and disconnect the low side hose from the A/C system.

4. MAINTENANCE

4.1 Keep the manifold in good working order.

4.2 Periodically replace O-rings and valve seats.

4.3 Be sure to lubricate O-rings with high vacuum grease.

4.4 Generally keep the manifold clean from dirt and grime to

improve product life.
