At switch-on the display shows the amount of freon, which is available within the internal bottle. If an error occurs
during the execution of the phases, the display will show an Error according to the following messages:
The message
ERR1 occurs if a minimal amount of freon is available within the inner bottle (<1kg). In this case the
freon has to be recovered from an external bottle (see chap. 6.0).
The message
ERR2 will be shown if a leak is detected within the air conditioning device of the vehicle during the
vacuum test (see chap. 6.3).
The message

The message
ERR4 will be shown when the internal bottle contains a too high amount of cooling liquid (>15 kg) and
this is just about to perform the recovery. In this case a charging of the external container has to be performed. (see
chap. 6.0).
The message
ERR5 will be shown if a “vacuum” is performed with the A/C station under pressure or if during the
vacuum phase a pressure rise occurs. (>0,5 bar). In this case a recovery has to be performed first (see chap. 6.4
The message
Attention 6 means that the interval for maintenance (150 h) is overdue – exchange the internal filter.
The message
Attention 7 will be shown if the recovery is being performed (manually) and the pressure of the plant,
which should be checked is under 0,5 bar – circulation empty. (chap. 6.2);
The message
Attention 8 will be shown if the recharging of the internal bottle and the external bottle is empty or is
emptying now before the programming of the charge is finished (Chap. 6.0).
