Evacuating the System On Ford?

The details for Evacuating the System on Ford vehicles.

The procedure is as follows :---


Evacuating the System
USING AN R-134A MANIFOLD GAUGE SET
USING AN R-134A SERVICE CENTER
The details for both are mentioned below :----

Using An R-134a Manifold Gauge Set



Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

NOTE
Ford Motor Company recommends use of an A/C service center to carry out recovery, evacuation and charging of the refrigerant system. If an A/C service center is not available, refrigerant system recovery, evacuation and charging may be accomplished using a separate recovery station, vacuum pump, charging meter and manifold gauge set.


NOTE
Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle's refrigerant system. It is necessary to leak-test all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are present.

  1. Connect the R-134a manifold gauge set to the low-side and high-side service gauge port valves.
  2. Connect the center (yellow) hose from the manifold gauge set to the suction port on the vacuum pump.
  3. Open all valves on the R-134a manifold gauge set and both service gauge port valves.
  4. Turn on the vacuum pump and evacuate the system until the low-pressure gauge reads at least 29.5 in. Hg (99.4 kPa) of vacuum and as close to 30 in. Hg (101.1 kPa ) as possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
  5. Close the high-side and low-side valves on the manifold gauge set (not the service gauge port valves) and turn OFF the vacuum pump.
  6. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If vacuum is not held for 5 minutes, leak test the system, repair the leak and evacuate the system again.

It is necessary to leak-test all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are present.

  1. Connect an R-134a service center to the low and high-pressure service gauge port valves following the instructions provided by the equipment manufacturer.
  2. Evacuate the system until the low-pressure gauge reads at least 29.5 in. Hg (99.4 kPa) of vacuum and as close to 30 in. Hg (101.1 kPa ) as possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
  3. Turn OFF the vacuum pump. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If vacuum is not held for 5 minutes, leak test the system, repair the leak and evacuate the system again.

This details will guide and help you to Evacuate the System.

Thanks.
