4) When the correct quantity has been reintegrated, close the new oil tap.
ATTENTION: the level of the oil in the container will fall, and consequently the quantity must
be calculated by subtraction. Upon termination of the oil reintegration operation you may go
on to the refrigerant fluid charging/reintegration phase.
CHARGING/REINTEGRATION PHASE
During this phase, the refrigerant fluid is returned to the A/C system circuit.
1) Press the SEL key until the “Charging” LED lights.
2) Proceed as described below to set the quantity of refrigerant fluid to be charged.
a. Press the ENTER key. The first digit on the left of the display will begin to flash.
Press the + key until the desired value appears. Likewise, press the ARROW
and + keys to change the values of the other digits. Press ENTER when setting
is completed to confirm the values. The quantity of fluid required for filling the
system is usually reported on a data plate in the engine compartment of the
vehicle. If the quantity is not known, consult the relevant system operating and
maintenance manuals.
b. The database can be used, if installed:
Press the ARROW key. The first number on the left will begin to flash on the
display. Find the relevant vehicle code on the special “table”. Use the ARROW
and + keys to enter the code. When finished, press ENTER to confirm. The
display will again show the quantity of refrigerant available and the machine will
be able to insert the correct amount of refrigerant.
NOTE: if the database has not been installed, “nodb” will appear on the display
for a couple of seconds, then the quantity of refrigerant available will reappear.
Please contact your retailer if you wish to install the database.
3) Open the high- and low-pressure taps (if previously closed) and press the START key.
ATTENTION: if the pressure in the bottle is higher than 8 bar, open the low pressure
tap only halfway (ca. 45° rotations) in order to avoid possible negative effects on the
A/C system.
4) The machine will stop automatically when the preset quantity has been charged.
5) Close the high- and low-pressure taps.
6) Start the vehicle motor and switch on the A/C system. And allow both to run for at least
3 minutes. At this point the system will be at steady state and it will be possible to
check the high and low pressure values on the relative pressure gauges.
7) Disconnect ONLY the high-pressure quick-connect coupling (if necessary, switch the
engine off). Then, with the A/C system still running, open the high- and low-pressure
taps to force the A/C system to draw up the refrigerant contained in the hoses.
8) After about 1 (one) minute, disconnect the low-pressure couplings the machine from
the vehicle A/C system and switch off the engine. Turn the main switch (i) to the 0
position.
ATTENTION: Should the pressure in the bottle be insufficient to charge the A/C system, it will
be necessary to force the system to take up the fluid by suction. With the quick-connect
couplings attached, CLOSE the high-pressure tap and run the A/C system with the low-
pressure tap open. In the case of a single high-pressure coupling, charge about 100g in
excess of the required quantity, since this amount will remain in the high-pressure hose at the
end of the operation.
