VACUUM PHASE
1. Upon completion ofthe RECOVERY phase itis possible to start the vacuum phase by
opening the high- and low-pres sure valves, press ing the SEL key until the LED
corresponding to “EVACUATE”lights,and then pres sing GO. The vacuum time can be
setas follows. Pres s SEL until the “EVACUATE”LED lights , then pres s ENTER; at this
point the firs t digit on the left ofthe displaywill begin to flash. Pres s the INCREASE key
until the desired digit appears. Likewise, press the ARROW and IN CREASE keys to
change the other digits .When s etting is complete, press the ENTER keyto confirm the
vacuum time value.
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. Clos e all the valves and read the vacuum value on pres sure gauges (A1) and (A2).
Wait for about 2 minutes, and then check that the pressure has not increased during
the interval. An increase in press ure s ignals leaks in the A/C s ystem. Locate and
eliminate the leaks;repeatthe vacuum phase.
WARNING: Avoid breathing A/C ref rigerant and lubri cant vapor mis t. Exposure may
irritate eyes, nose, and throat. To remove HFC-134a from the A/C system, use service
eq uipment certified to meet the requirements of SAE J2210 (HFC-134a recycling
equi pment). Additional health and safety informa tion may be obtai ne d from additional
refrigerant and lubrica nt manufac ture rs.
N EW OIL IN J ECTION
You can injectvirgin 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 s ame amountofoil thatwas 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 s ystem bythe deep vacuum that was obtained while evacuating.
The s ubsequent charging ofrefrigerantwill ensure all ofthe oil will be charged from the lines
and hoses.

W ARNING: Always w ear safety goggles and hand protection when w orking with
refrigerants. Failure to follow these procedures may result in serious injury. Due to the
extreme cold temperatures associatedwith the use of refrigerants, any contact w ith the
eye can cause blindne ss and contact with the bar e skin can cause burns or frostbite.
CAU TION : When cha rging a vehicle do not lea n on the machine as this may aff ect the
scale readings. Inaccurate w eight measurements may result. The vehicle system can
be dam aged if weights are not mea sure d acc uratel y.
During this phase,the correctrefri gerantcharge is returned to the vehicle’s A/C system.
1. Pres s the SEL key until the “RECHARGE”LED lights.
2. Proceed as described below to setthe quantityofrefrigerant fluid to be charged. Pres s
the ENTER key. The firs t digit on the left of the display will begin to flash. Press the
INCREASE key until the desired value appears. (Digits read in pounds and ounces, or
kilograms .) Likewise, pres s the ARROW and INCREASE keys to change the values of
the other digits . Press ENTER when setting is completed to confirm the values . The
quantityoffluid required for filling the system is usuallyreported on a data plate in the
engine compartment of the vehicle. If the quantity is not known, consult the relevant
system operating and maintenance m anuals.
