4.1 MESSAGES ON THE DISPLAY
All signals will be displayed on the LCD by sliding messages.
When switching on the machine the display shows the amount of freon, which is available inside the internal
bottle.
If an error occurs during the execution of the phases, the display will show the following Errors and mes-
sages:
ERROR 1 – when a minimal amount of freon is available inside the internal bottle (<1kg). In this case the
freon has to be recovered from an external bottle (Chap. 6.0).
ERROR 2 – when a leak in the air conditioning device of the vehicle is detected during the vacuum test
(Chap. 6.3).
ERROR 3 – inactive.
ERROR 4 – when the amount of cooling liquid contained in the internal bottle is too high (> 10 kg) and you
try to perform the recovery. In this case you should perform a charge in an external container. (Chap. 6.0).
ERROR 5 – when you try to perform a “vacuum” with the A/C station under pressure or if during the vacuum
phase a pressure increase occurs (> 0,5 bar). In this case, you should perform a recovery first (Chap. 6.4).
ATTENTION 6 – means that the interval for maintenance (150 h) is overdue – replace the internal filter.
ATTENTION 7 – when you try to perform the recovery (manually) and the pressure of the system to be
checked is less than 0,5 bar – empty circuit. (Chap. 6.2).
ATTENTION 8 – when you try to charge the internal bottle and the external bottle is empty or it becomes
empty before the set charge is finished (Chap. 6.0).
ATTENTION 9 – when the recovery from the external bottle is finished, you have to close the tap of the bot-
tle and press the key “ENTER” to recover the gas in the hoses.
ERROR: Insufficient quantity of gas to perform the flushing of the AC system, it is necessary to have at least
4 kg of gas.
PLEASE NOTE: In some versions of the software the display may show the message “ERROR” instead of
“ATTENTION” (e.g. “ERROR 8” is the same as “ATTENTION 8”).
