INSUFFICIENT GAS ALARM: Beeper advise when the charging quantity set exceeds the
difference between availability and bottle minimum.

PRELIMINARY OPERATIONS

Check that the main switch (i) is set to O. Check that all the MACHINE taps are closed.
Connect the MACHINE to the electrical supply and switch on. Check that the vacuum pump oil
level indicator shows at least one-half full. If the level is lower, add oil as explained in the
MAINTENANCE section. Check that in the new oil container (n) there are at least 100 cc of the
oil recommended by the manufacturer of the vehicle A/C system. Check that the oil level in
tank (m) is < 200 cc. Check on the MACHINE display that there are at roughly 3 kg of
refrigerant in the bottle. Should this not be the case, fill the on-board MACHINE bottle from an
external bottle of appropriate refrigerant following the procedure described in the
MAINTENANCE section.

PURGING NON-CONDENSABLE GASES

Before every use, check if there is air in the bottle: Select MANUAL AIR PURGING from
MAINTENANCE. Read the bottle pressure on the bottle manometer (ref A4, Fig.9), if the bottle
pressure is higher than TARGET PRESSURE pull the valve ring (ref 1, Fig.18) using a
screwdriver (ref 2, Fig.18) to purge the air making the bottle pressure drop, then release the
valve ring when the TARGET PRESSURE is reached.
