VACUUM PHASE
1.Upon completion of the RECOVERY phase it is possible to start the vacuum phase by opening the high- and
2.During the vacuum phase, the display will clock its duration. Leave the machine running until the displayreads 0000 and the pump stops automatically.
3.Close all the valves and read the vacuum value on pressure gauges (A1) and (A2). Wait for about 2 minutes, and then check that the pressure has not increased during the interval. An increase in pressure signals leaks in the A/C system. Locate and eliminate the leaks; repeat the vacuum phase.
WARNING: Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose, and throat. To remove
NEW OIL INJECTION
You can inject virgin lubricating oil into the vehicle A/C system at this time. Make certain that the Oil Charge Bottle has sufficient quantity of oil. Cautiously open the Oil Charge valve until the same amount of oil that was recovered in the RECOVERY AND RECYCLING operation is removed from the container and replaced back into the vehicle's A/C system. The oil will be drawn into the vehicle A/C system by the deep vacuum that was obtained while evacuating. The subsequent charging of refrigerant will ensure all of the oil will be charged from the lines and hoses.
RECHARGE AN A/C SYSTEM
WARNING: Always wear safety goggles and hand protection when working with refrigerants. Failure to follow these procedures may result in serious injury. Due to the extreme cold temperatures associated with the use of refrigerants, any contact with the eye can cause blindness and contact with the bare skin can cause burns or frostbite.
CAUTION: When charging a vehicle do not lean on the machine as this may affect the scale readings. Inaccurate weight measurements may result. The vehicle system can be damaged if weights are not measured accurately.
During this phase, the correct refrigerant charge is returned to the vehicle’s A/C system.
1.Press the SEL keyuntil the “RECHARGE” LED lights.
2.Proceed as described below to set the quantity of refrigerant fluid to be charged. Press the ENTER key. The first digit on the left of the display will begin to flash. Press the INCREASE keyuntil the desired value appears. (Digits read in pounds and ounces, or kilograms.) Likewise, press the ARROW and INCREASE keys to change the values of the other digits. Press ENTER when setting is completed to confirm the values. The quantity of fluid required for filling the system is usually reported on a data plate in the engine compartment of the vehicle. If the quantity is not known, consult the relevant system operating and maintenance manuals.
