charging equipment. Refer to the operating instructions supplied by the equipment manufacturer for proper care and
use of this equipment.
A manifold gauge set may be needed with some recovery/recycling/charging equipment. The service hoses on the
gauge set being used should have manual (turn wheel), or automatic back-flow valves at the service port connector
ends. This will prevent refrigerant from being released into the atmosphere.
MANIFOLD GAUGE SET CONNECTIONS
CAUTION: Do not use an R-12 manifold gauge set on an R-134a system. The refrigerants are not compatible
and system damage will result.
LOW PRESSURE GAUGE HOSE The low pressure hose (Blue with Black stripe) attaches to the suction service
port. This port is located on the suction line near the driver side of the engine compartment.
HIGH PRESSURE GAUGE HOSE The high pressure hose (Red with Black stripe) attaches to the discharge service
port. This port is located on the discharge line between the compressor and the condenser inlet behind the front
grille.
RECOVERY/RECYCLING/EVACUATION/CHARGING HOSE The center manifold hose (Yellow, or White, with Black
stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on
the manifold gauge set are opened, the refrigerant in the system will escape through this hose.
STANDARD PROCEDURE - REFRIGERANT RECOVERY
WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PER-
FORMING THE FOLLOWING OPERATION. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARN-
ING).
A R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 must be used to recover
the refrigerant from an R-134a refrigerant system. Refer to the operating instructions supplied by the equipment
manufacturer for the proper care and use of this equipment.
STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE
WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PER-
FORMING THE FOLLOWING OPERATION. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARN-
ING).
If the refrigerant system has been open to the atmosphere, it must be evacuated before the system can be charged.
If moisture and air enters the system and becomes mixed with the refrigerant, the compressor head pressure will
rise above acceptable operating levels. This will reduce the performance of the air conditioner and damage the
compressor. Evacuating the refrigerant system will remove the air and boil the moisture out of the system at near
room temperature. To evacuate the refrigerant system, use the following procedure:
1. Connect a R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 and a manifold
gauge set to the refrigerant system of the vehicle.
2. Open the low and high side valves and start the charging station vacuum pump. When the suction gauge reads
88 kPa (26 in. Hg.) vacuum or greater, close all of the valves and turn off the vacuum pump.
a. If the refrigerant system fails to reach the specified vacuum, the system has a leak that must be corrected.
(Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - DIAGNOSIS AND TESTING).
b. If the refrigerant system maintains the specified vacuum for five minutes, restart the vacuum pump, open the
suction and discharge valves and evacuate the system for an additional ten minutes.
3. Close all of the valves, and turn off the charging station vacuum pump.
4. The refrigerant system is now ready to be charged with R-134a refrigerant. (Refer to 24 - HEATING & AIR CON-
DITIONING/PLUMBING - STANDARD PROCEDURE).
