If using approved Recovery/Recycling/Charging Center (023-00105 or 023-00150), connect to high-side and low-side service valves. See SERVICE VALVE LOCATIONS under SYSTEM SERVICE VALVES. Operate charging center according to manufacturer's instructions. Charge system with specified amount of refrigerant and refrigerant oil. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS article. Check amount of refrigerant oil in system before adding oil. See COMPRESSOR REFRIGERANT OIL CHECKING article.
If using manifold gauge set, connect to high-side and low-side service valves. See SERVICE VALVE LOCATIONS under SYSTEM SERVICE VALVES. Connect 2 hoses with shutoff valves to manifold gauge set center port. Connect one hose to vacuum pump and other hose to refrigerant container. Weight of refrigerant container before and after charging can be used to determine amount of refrigerant drawn into system. Using vacuum pump, purge air from center hoses.
Fully open manifold gauge set low-side valve and refrigerant container valve to allow refrigerant to enter A/C system. When no more refrigerant is being drawn into A/C system, start engine and allow to idle. Select MAX A/C, set blower motor speed to maximum and allow remaining refrigerant to be drawn into A/C system.
NOTE: When ambient air temperature is high, it may be necessary to use an external cooling fan to blow air through condenser and radiator.
When proper amount of refrigerant has been added, close refrigerant container valve. Allow any refrigerant remaining in hose to be drawn into A/C system. When low-side pressure decreases to about 30 psi (2.1 kg/cm² ), close center valve on manifold gauge set. Ensure A/C system is operating properly. Disconnect manifold gauge set. Install service port caps. Check system for leaks. See LEAK TESTING .
