procedure to reduce the risk of comebacks that can be caused by charging excess
NCGS into an A/C system.

VACUUM

Use the quick-connect couplings to connect the hoses to the A/C system, bearing in mind that
BLUE must be connected to the low pressure side and RED to high pressure. If the system is
equipped with a single quick-connect coupling for high or low pressure, connect only the
relative hose. Select the assisted procedure by pressing ENTER when "Assisted Procedure"
flashes on the LCD. Select the vacuum operation by pressing ENTER when the message
"Vacuum xx min." flashes on the LCD. Set the vacuum time only if different from that
previously used. Press ENTER to confirm. Open the high and low-pressure taps of the
machine and press START. After the first 10 minutes of this phase, the machine will test for
leaks in the A/C system (WARNING! If vacuum time < 10 minutes this test is excluded). If
leaks are found, the machine will stop automatically and display the A/C SYSTEM LEAKS
alarm. Detection of micro-leaks is not guaranteed. If the A/C system seal is good, the machine
will continue with the vacuum phase.

ADDING NEW OIL

This operation can be carried out ONLY following a vacuum operation and before charging.
Select the assisted procedure by pressing ENTER when the "ASSISTED PROCEDURE"
message flashes on the LCD. Select the OIL by pressing ENTER when "OIL XX CC" flashes
on the LCD. Set the volume of new oil to be added, in cc. Press ENTER to confirm. Open the
high- and low-pressure taps (if the A/C system is equipped with a single quick-connect coupling
for high or low pressure, open only the relative tap) of the machine and press START.

ADDING UV DYE (If Equipped with DK300)

This operation can be carried out only following a vacuum procedure and before charging.
Select the assisted procedure when the "ASSISTED PROCEDURE" message flashes on the
LCD, and press ENTER. Select "OIL AND UV DYE;" when "Oil xx cc" flashes, select UV DYE
xx CC and set the volume of dye to be added, in cc. Press ENTER to confirm. Open the high-
and low-pressure taps (in the case of an A/C system with only one pressure coupling—high or
low—open only the relative tap) on the machine and press START.

CHARGING THE A/C SYSTEM

Select the ASSISTED PROCEDURE by pressing ENTER when the "Assisted Procedure"
message flashes on the LCD. Select charging by pressing ENTER when "CHARGING XXXX
G" flashes on the LCD.
Set the quantity of fluid to be reintegrated as explained below.
1. MANUAL OPERATION: set the quantity of refrigerant in pound for the A/C system to be
charged. For example, for 1lb 7 oz., press key 1, key 0, and key 7, "Charging 1:07 lb".
After setting the quantity, press ENTER to confirm.
On most systems the quantity of fluid to be reintegrated is given on the plate inside the
engine compartment of the vehicle. If you do not know the correct quantity, consult the
relevant manuals.
