6.3 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
final 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: 7-8 kg.
- Connect the red hose of the station to an external bottle.
- Note: it is necessary to recover the gas in liquid phase! If the bottle is not equipped with double riser, put
it upside-down before making the recovery.
- Select Gas Recharge from the main menu.
- Confirm your choice.
- Set the gas quantity that you want to recover.
- For the use of the encoder and the keyboard please refer to chapter 6.0
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 level (17,5kg) on the display will appear the error message and the message 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 17,5kg.
THE INTERNAL BOTTLE IS SUPPLIED WITH A MECHANICAL SAFETY VALVE
