Safety devices
A) Pressure relief valve on internal gas tank: releases pressure if 18 Bar are exceeded in the gas tank.
B) Safety fan: ventilates the unit continuously when in use. The software displays a warning message in
case of failure of this fan. This device applies to models designed for R1234YF refrigerant
Scrapping of the unit
-Do not treat the unit as mixed solid waste for scrapping but take it to pieces (waste separation).
- Refer to the specific collection points for waste of electric and electronic devices (AEE), according
to the relevant CEE RAEE 2002/95/EC, 2002/96/EC2003/108/EC regulation.
- The vacuum pump and the containers of new and used oil contain mineral and synthetic oil.
Therefore, specific regulations for scrapping have to be followed. The same procedure has to be
followed for refrigerant gas residuals in the storage bottle. Also the exhaust oil drained from the
pump is a specific waste and has to be collected according to the relevant regulations in force.

INSTALLATION
Connection of tubes and leak test
Connect the charging hoses to the unit (high pressure = RED, low pressure = BLUE). Make sure that the
quick couplings are in position “CLOSED” (eventually, turn handle counter-clockwise to close)
Carry out a vacuum cycle of one/two minutes followed by a leak test under vacuum. The above procedure
avoids that air residuals are left in the hoses and checks for eventual leaks. (See the relevant instructions)
The vacuum and the following leak test the test should be repeated whenever the charging hoses could
have been contaminated with air.
Check if the setting relevant to the length of the hoses is correct (select “OPTIONS AND SETTINGS” then
“HOSE LENGTH” and modify if needed, by means of the buttons “UP” and “DOWN” (3 Mis default setting)
If the hose length, on the opposite, is set to “0” (zero), at the end of the working cycle, the unit will
not calculate the gas remaining in the hoses at the end of the working cycle and will lead the user to
suction the gas residuals in the A/C system of the vehicle, instead.
(in case of a pressure test which is not preceded by a standard working cycle, the unit recovers the gas
residuals in the vehicle by default, regardless to the above setting)
Filling of internal bottle
The unit is delivered with the empty internal gas bottle for safety reasons. It is therefore
necessary to fill the bottle with a refrigerant g quantity not lower than 2 Kg and not higher than
eighty percent of the maximum nominal capacity of the reservoir (this percentage may vary
according to local safety rules). In order to fill the internal tank please follow the relevant
instructions of the present manual. To connect to the bottle, use the HP hose with the HP
quick coupling (a special coupling is required to couple the quick coupling to the bottle, see
hereunder)
Connecting to power feeding
Connect to proper power feeding according to the unit's technical specifications
Position on an even surface
During the operations, the unit must be located on a flat and leveled surface in order to
correctly perform the weight measurements and in order to comply to the safety rules.

MENU DESCRIPTION
Main menu and main working cycle description
After switching on the unit displays the SW version and performs an automatic test to check if there are any
gas leaks in the machine and, eventually, stops the operation.
Switch on the unit which will display
Firmware version and refrigerant type
The unit automatically starts a series
of tests:
A. Recovery check
B. Drain check
C. Vacuum check
D. Safety Check
In case the test fails, the unit displays
a warning message (in the case at the
right, a leak in the system). Call the
service if such a message appears.
After the test you land in the “Home
Page”:
1 –Home page Icon
2 –Gas quantity in the tank
3 –Theoretical tank pressure
4 –Actual gas temperature
NOTE:
Release of Non-Condensable Gases
If the theoretical gas tank pressure shown on the home page (see above n. 3)
calculated on the base of the gas temperature is signficantly lower than the actual
tank pressure (shown on the gas tank manometer) the refrigerant is contaminated
by non-condensable gases (NCG’s) The unit automatically releases NCG’s during
the vacuum cycle, but the user (for instance in case of failure of the NCG release
valve) may also manually release by pulling the ring on the max pressure valve until
the theoretucal and the actual presur evalues comply. NOTE: If the theoretical gas
pressure, on the opposite, is higher than the actual value shown on the tank
manometer the gas quantity in the tank is too low .

WORKING CYCLE
Automatic A/C service cycle, with automatic or manual working parameter setting
NOTE: always wear safety gloves and
protection glasses when servicing an A/C
system!
You may perfom the A/C service cycle in three ways :
A) AUTOMATIC working cycle all working phases performed in one step
B) MANUAL working cycle single working phases performed one by one
C) SEMI-AUTOMATIC working cycle recovery, oil drain, vacuum first step. Oil/dye and gas charging made
after the setting of the oil quantity by the user.
In all cases, there is no setting needed for the recovery phase. The vacuum/vacuum test time and the refrigerant
quantity
1. Can be taken from the internal DATABASE or
2. Can be defined by the user (manual setting of the parameters)
The dye quantity has to be set by the user (default is 0 g)
The new oil quantity, can be set in two ways:
1. It can be set by the user with no regard to the the recovered oil (“MANUAL” oil setting)
2. It can be set by the user according to the recovered quantity. In this case, the oil quantity has to be set on SA
Pressing on the DOWN button below 0 the letters SA (“SemiAutmatic”) are displayed and the unit stops after
the vacuum to allow the user to evaluate the recovered oil quntity) and set the same new oil amount.
