Operating Instructions
Automatic Function
The AUTOMATIC function allows a user to perform an
automatic recovery, vacuum, leak test, and/or charge
sequence. A total automatic sequence may take up to an
hour to complete.
1. Connect high-side (red) and low-side (blue) service hoses
to the A/C system.
2. Open the service hose coupler valves by turning the
collars clockwise.
3. Select AUTOMATIC from the MAIN MENU. The display
shows
Vacuum Time: XX:XX
Vacuum Leak Test: ON
Charge: XX.XXX kg on High Side
Additional Oil: XXX ml
4. Use the numeric keypad to enter the desired length
of vacuum.
5. Using the arrow keys, maneuver downwards to choose
whether to perform a vacuum leak test or not. ON is the
default setting. To toggle, select on the control panel.
6. Use the arrow keys and the numeric keypad to enter the
desired charge amount. Select to change units.
7. Using the arrow keys, maneuver to the “charge path
selection.” High Side is default. To change, select
on the control panel. This will allow the user to toggle
between high, low, and both side charge paths. The text
on the display will change to the current selection.
8. Using the arrow keys, maneuver to the “additional oil”
entry eld. Use the numeric keypad to enter the desired
additional oil inject amount. Select to change units.
9. Select to begin the AUTOMATIC cycle. The unit will
now automatically proceed through all applicable functions:
RECOVER, VACUUM, and CHARGE. If the vehicle being
serviced has previously undergone a recover and vacuum
procedure, the machine will only perform a CHARGE.
10. When the AUTOMATIC COMPLETE
screen appears, it includes a summary of
results. The user may select to print the
summary, if a printer is installed. Select
to proceed.
11. The user will be prompted to close the
coupler valves and disconnect the hoses
from the vehicle. Select to recover any
remaining refrigerant from the hoses. Once
the clear is complete, the machine will
return to the Main Menu.
The vehicle A/C system is now ready to use.
Notes:
• The CHARGE function for vehicles
equipped with a single-service fitting
should be carried out manually according
to procedures in the vehicle manufacturer’s
service manual.
• After the RECOVER process, the user will
be prompted to “Check oil bottle and enter
oil to be injected.” The entered oil inject
amount should be equal to the amount of
oil drained and can be found by looking at
the graduations on the drain bottle.
• If RECOVER was not performed,
the amount of oil to be injected may
be entered while programming the
CHARGE information.
• If problems are encountered during the
automatic sequence, an audio alert sounds
three times. The sequence remains paused
until the user enters a decision regarding
how to proceed.
WARNING: To prevent personal
injury while working with refrigerant,
read and follow the instructions
and warnings in this manual, and
wear protective equipment such as
goggles and gloves.
