6.0 RECHARGE OF GAS (INTERNAL BOTTLE CHARGE)
The amount of freon, which is present inside the internal bottle, has been charged in order to perform the fi-
nal inspection and the control of the station and it is sufficient to perform a complete charge. Therefore it is
advisable to charge the necessary gas using an external bottle when switching on the machine.
Total amount of gas suggested: 4-6 Kg
To charge the internal bottle select Gas Recharge and set the desired quantity.
Note: the machine is equipped with a safety device that checks the gas of quantity inside the internal
bottle; if you try to perform a recovery with the bottle with a quantity of gas inside esxceeding the
alalrm leve (10kg) on the display will appear “ERROR 4” and the messahe of full bottle. In this case
you can perform vacuuming and charging operations only until the quantity of gas inside the bottle
is less than 10kg.
If the quantity of gas inside the bottle is not sufficient (less than 1 kg), after the setting, the display will show
“ERROR 1” and the message of insufficient quantity of gas inside the bottle, in such a case you should follow
the instructions outlined ion “gas recharge”.
