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.
