CAP. 10 - A/C SYSTEM RECHARGE 42 / 77 ENGLISH
M
ULTIGAS 8500 PLUS
10.2 NON-CONDENSABLE GAS DISCHARGE
The station is equipped with the AIR PURGE SYSTEM function, which allows automatically detecting
and purging non-condensable gas (mainly air) accumulated within the tank.
Periodically, basically every week, the station, the first time it is switched on that day, will suggest
running the AIR PURGE SYSTEM procedure
If the station detects non-condensable gas in the tank, it will automatically run the non-condensable
gas discharge procedure.
Running this procedure is very important to ensure the ideal working parameters for the station
operation. The presence of non-condensable gas in the tank will increase the pressure inside the
tank and, therefore, will slow down and reduce the efficiency of recharge cycles on the vehicle.
The AIR PURGE SYSTEM function can be disabled from the setup menu. In this case, execution of the
procedure will no longer be suggested when switching on the station.
The procedure will take a few minutes, and its duration may vary according to the amount of non-
condensable gas within the tank.
If needed, the non-condensable gas discharge procedure can be executed at any time from the
maintenance menu.
WARNING: Leave the quick coupling taps closed when the unit is not in use and
at the end of vehicle service operations.
WARNING: For the Air Purge System procedure to be executed manually, the
station must have been off for at least one hour.
