Do not violate for any reason at all the safety devices the unit is equipped with, like the high pressure valve of the internal reservoir. Do not fill compressed air in the lines of the service unit or in the vehicle aircon system (a mixture of air and refrigerant can be flammable or explosive); Please be aware that whatsoever damages due to a wrong or improper use of the recharging station will not be covered by our warranty. Consumables like packing and seals for hoses and quick couplings, fuses and damages occurred during transport are not part of the warranty Warning icons used in the present manual Caution! Connect to 230V socket 50Hz Wear gloves when handling refrigerants Wear goggles Protect against when handling rain refrigerants Read instruction manual carefully Safety devices A) Pressure relief valvse on internal gas tank: releases pressure if 16 Bar are exceeded in the gas tank. FAST20FAST20F only: B) Max pressure sensor. In case of a failure of the pressure relief valve and if the pressure in the unit exceeds 20 Bar, the safety system will switch off the unit and light a warning signal on the back of the machine (see par. 3.2 Description of the unit n. 19 Warning light ) After having repaired the unit, press on the max pressure reset button (see par.3.2 description of the unit n. 20 Reset button ) in order to switch on the unit. 1.3 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 the specific regulations for scrapping have to be followed. The same procedure has to be followed for the refrigerant gas residual in the storage bottle. The exhaust oil drained from the pump is a specific waste and has to be collected according to the relevant regulations in force. 4/23

5 2. Installation and preparing for use 2.1 Unpacking and checking of the unit Check the integrity of the packaging to exclude damages occurred during transport. Check the entirety of the equipment and of the relevant accessories. Not conformities, if any, have to be pointed out immediately and written down on the transport documents Checking the accessories delivered with the unit Charging hoses HP+LP Quick couplings HP+LP Feeding cable Calibration hook (fixing screw during transport) 2.2 Preparing for use Removal of safety device Before using the unit for the first time remove the safety screw which is screwed to the tank load cell for protection (see fig. 1). It is recommended to check the regular functioning of the load cell, for example by hooking a known weight to the bottle to check the correspondence with the weight shown on the display (see relevant paragraph). 1 Rivet nut to fix the load cell during transport 2 Threaded hole to fix the calibration hook to the load cell 3 Fixing bolts of the load cell Oil level checking of vacuum pump Check the level of hydraulic oil in the vacuum pump and, if necessary, fill up to the level (about half of the spy glass) Medium level 5/23

6 2.2.3 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. 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 If the hose length 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 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 correclty perform the weight measurements and in order to comply to the safety rules. 6/23

7 3. Use 3.1 Preliminary checks Connect the feeding cable to the mains (220V AC single phase) and turn on the main switch.

10 3.3 General description of the working cycles 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. (the initial test is mandatory for R1234yf units only. Press on Exit to bypass the leak control and continue to work in case you are using a R134a unit). Following data are shown on the starting page: a) the weight of the refrigerant in the internal bottle b) the temperature of the gas in the tank and c) the corresponding (theoretic) pressure value of R134a or HFO12234yf d) the icons for the selection of the available functions. c a d b Icon Meaning Refers to the current refrigerant quantity in the internal bottle Temperature and theoretical pressure of the refrigerant in the internal reservoir. (the actual pressure can be read on the analogical gauge see above) Initial display Access to the internal DATABASE, both AUTOMATIC/MANUAL working modes Access to both the MANUAL / AUTOMATIC working modes, no data bank access ACCESSORIES: available accessory functions OPTIONS: selection of the different functioning options SET UP: setting of the basic information parameters PRINT last working cycle data 10/23

11 3.3.1 Release of Non-Condensable Gases If the value of the (theoretical) gas pressure (see above point c) calculated on the base of the gas temperature measured by the temperature probe - is significantly higher than the actual pressure of the gas in the tank (you may read its value by means of the tank pressure gauge, see above part no.3) the refrigerant is mixed with non-condensable gases. (NCG)The unit automatically releases the gases during the vacuum phase through the NG release valve You may also pull the ring on the max pressure valve to release the NCG until the theoretical and the actual pressure comply. 16 Note: if the value on the pressure gauge, on the opposite, is lower than the calculated one, the gas quantity in the tank is too low. 3.4 Analytical description of the working cycles Model choice through the internal DATABASE Select the working mode through data bank, browse the list of car manufacturers, types and the versions of the car you are going to service. After the final selection the unit shows the same display as in the MANUAL -AUTOMATIC mode (see here following) but indicates the recommended refrigerant quantity for the specific car model of your choice. By pressing selecting START and ENTER, the unit starts an automatic working cycle, as explained more in detail hereafter. Otherwise is also possible to select the single working cycles, and press ENTER in order to perform that particular cycle only MANUAL /AUTOMATIC mode Select MANUAL in order to reach the AUTOMATIC/MANUAL working cycle selection (all cycles can be done automatically or you can perform one cycle at a time) The unit will show the following display: Icon Meaning START: immediate start of AUTOMATIC and complete working cycle according to the parameters shown on display (all cycles performed at one time) RECOVERY: immediate start of refrigerant gas recovery from the vehicle 11/23

In case a vehicle model has been selected from the data bank the various parameters are already indicated under their relevant icon, otherwise the parameters have to be set manually. The working cycles can be performed one by one or all together. The performed cycles are: a) Recovery of refrigerant gas form the vehicle b) Oil separation from recovered refrigerant and draining into proper container c) Vacuum (for the set duration) d) Leak test under vacuum (for the set duration) e) New oil charging f) Charge of dyeing substances (according to set quantity) g) Partial gas recharging (in case of HFO1234YF systems only) h) Leak test under pressure (in case of HFO1234YF systems only) i) Recovery of the refrigerant (in case of HFO1234YF systems only) j) Final gas recharging into the vehicle (according to set quantity) Note: in order to change a single parameters of an automatic cycle, browse the menu until you reach the cycle whose values have to be changed, press ENTER, change the values and press EXIT to return to START. If, on the opposite, you want to perform the single working cycle only, press ENTER after having changed the values Recovery By selecting RECOVERY the unit carries out the recovery of the gas in the A/C system and discharges the exhaust oil. In order to assure a perfect recovery and oil separation, the unit modulates the gas flow in relation to its pressure, therefore recovery cycles may be alternated by intervals. The operation is followed by a waiting period to check if there are any gas residuals in the system. The length of the waiting time can be set in the OPTIONS menu Vacuum By selecting VACUUM it will be possible to set the duration of the vacuum. Press EXIT to return to START If you press ENTER again the unit checks that the pressure allows to carry out the vacuum. The vacuum cycle is automatically followed by a leak test cycle under vacuum according to the set parameters ) Note: the unit gives out acoustic signals until a good vacuum level is reached. In case of a 12/23

13 remarkable leakage, when this level is never reached, the unit continues the signals and therefore warns the operator Leak test under vacuum By selecting LEAK TEST, it will be possible to set the duration of the leak test under vacuum. By pressing the button ENTER again, the unit will carry out a capacity test under vacuum according to the parameters set before. (select this option only if the vacuum in the system has already been carried out) Oil injection into A/C system By selecting icon OIL INJECTION, you access the oil injection selection menu It is possible to set the oil quantity to be injected into the A/C system. It is suggested to set a quantity of 10/15 g for a medium sized A/C system. 1) it could be necessary to adjust the oil viscosity parameter (see menu settings, here following) if the charged oil quantity is not correct. This could be due to particular environment conditions; the default settings allows accurate oil charging for medium viscosity oil at a temperature of C. Always check the presence of dye liquid or oil in the relevant container BEFORE starting the procedure.) Note(1): in order to charge oil in the A/C systems previously make a vacuum cycle. Note(2): the oil charging cycle is designed in order to charge small quantities of oil in the system. It is not recommended in case of charging bigger quantities Dye injection into A/C system By selecting the icon and DYE INJECTION it is possible to set the quantity of dye liquid to be injected into the A/C system. By pressing button Enter again, the unit opens the valve for the necessary time to inject the desired quantity. Always check the presence of dye liquid or oil in the relevant container BEFORE starting the procedure.) Refrigerant gas recharging into A/C system By selecting RECHARGING it is possible to set the refrigerant quantity to be injected into the A/C system (It is furthermore be possible to derive the quantity from a data bank as shown above) At the end of the cycle, the operator is requested to close the quick couplings on the vehicle in order to start the recovery cycle of gas residuals in the connecting tubes. Note(1)If, on the opposite you wish to suction the gas residuals of the hoses into the vehicles' A/C system, you should have set the hose length to the value 0 (see hereunder p Setting the hose length ) Note(2) The refrigerant charging is carried out thanks to the pressure difference between the tank and the A/C system. The unit automatically increases the tank temperature to increase its pressure during the vacuum time It is therefore advisable to carry out a recharging only after having carried a reasonable vacuum cycle. Note(3) in order to recharge the A/C system it is necessary that the internal bottle contains a sufficient gas quantity. If not enough gas is contained in the tank, the unit displays a warning message (to refill the internal gas tank see the relevant paragraph hereunder) 13/23
