you to quickly attach and detach your air Air Fitting (13) supply hose from this tool.

Operation

It is unlawful and hazardous to discharge refrig- erants into the atmosphere. Before beginning work with this tool, safely capture refrigerants using an

approved refrigerant recovery system, and dispose of them properly. Contact the

EPA for important certification regulations and other regulations that apply, see Front Cover.

Warning: The AC system must be turned OFF during this procedure.

1.Empty the AC system of refrigerants, in preparation for purging and refilling.

2.Attach your air pressure hose (not in- cluded) to the Air Fitting (13) either by threading it directly on, or by using a quick release fitting.

3.Attach the R-134a Manifold fitting to the AC drain port in your vehicle.This is a quick release fitting. NOTE: The drain port is generally the lower of the two R-134a manifold ports in your system, and is lo- cated downstream from the compressor in your system. Please refer to your ve-

R-134a Connector (8)	hicle owner or shop manual for specific
	information on your vehicle.

4.Turn on the Air Vacuum Pump by activating your air compressor (not included). Recommended pressure is 40 PSI, and not to exceed 90 PSI.

5.The vacuum will build for approximately 2 minutes, before reaching its full power. Allow the pump to draw vacuum on the system for approximately 5-10 minutes to thoroughly remove all moisture from the system.

6.The gauge (not included) should show negative pressure and maintain that reading for 10 minutes. If it rises back towards 0, there may be a leak in the system.

7.Remove the R-134a manifold fitting, and turn off your air compressor.
