ALARMS

HIGH PRESSURE ALARM: Beeper and LCD advise when the pressure of the fluid in the
circuit reaches 290 psi (20 bar). The recovery operation is automatically interrupted.
FULL BOTTLE ALARM: Beeper and LCD advises when the bottle is filled to more than 80% of
maximum capacity; that is, 40lbs (17kg). The RECOVERY operation is automatically
interrupted (to cancel this alarm, charge one or more A/C systems before recovering any more
refrigerant).
EMPTY BOTTLE ALARM: Beeper and LCD advise when the quantity of refrigerant fluid
contained in the bottle is low.
SERVICE ALARM: Beeper and LCD advise whenever the total recovered refrigerant amounts
to 132 lb (60kg). To deactivate the alarm, replace the filters and the vacuum pump oil. A code
for resetting the service alarm is supplied with the spare filters.
INSUFFICIENT GAS ALARM: Beeper and LCD advise when the charging quantity set
exceeds the amount available.

PRELIMINARY OPERATIONS

Check that the main switch (i) is set to 0. 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
used oil container (m) is < 200 cc. Check the machine's display that there are at least 4.5 lbs
(2 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
ROUTINE MAINTENANCE section.

AUTOMATIC PROCEDURE

In the automatic mode, the recovery and recycling, oil discharge, and vacuum operations are
performed in a sequence automatically. New oil must be added after the vacuum pump has
stopped. The machine then goes on to automatic refrigerant charging when the start button is
pressed.
Connect the hoses to the A/C system with the quick-connect couplings, bearing in mind that
BLUE must be connected to the low-pressure side and RED to high pressure. Open the quick-
connect valves. If the A/C system is equipped with a single quick-connect coupling for high or
low pressure, connect and open only the relative quick-connect coupling and hose.
Check that the high and low-pressure taps are closed. Start the vehicle engine and switch on
the air conditioner. Allow both to run for about 5 to 10 minutes with the passenger compartment
fan at full speed. Switch off the vehicle engine.
The machine is equipped with a 4-line LCD display, maximum 20 characters per line. On the
menus the selected line flashes; in this manual it is enclosed in quotation marks. Select the
automatic procedure; that is, press ENTER when "Automatic Procedure" flashes on the LCD.
