1. General information for the user
1.1 Preliminary instructions/proper use
The present recycling and recharging unit for A/C systems is meant for commercial purposes and is thought
to be used by trained personnel only being aware of the principles of refrigeration, conscious of the hazards
which may derive from equipment working under pressure with substances at very low boiling temperature.
We advise to read the present instruction manual carefully and to strictly comply with the given
information, paying particular attention to the safety regulations. We shall decline any
responsibility resulting from the improper use of the equipment, use for purposes other than
those described in the present operating manual, incorrect operation, damages resulting from
external influences.
Always keep the unit in vertical position in order to avoid oil leaks and the compressor to be damaged.
1.2 General safety regulations
✔ Read the instructions for use careful before starting to operate with this Aircon service unit;
✔
Follow the informations and the instructions
✔ Observe any instructions on servicing vehicle aircon systems which apply at your company;
✔ Use with R134a refrigerant indicated on the data plate (R-134a for Fast20X/Ecos20X; HFO-1234YF
for Fast20XYF);
✔ Do not make modifications to the service unit;
✔ Only employ original spare parts and accessories;
✔ Use authorized additives or consumables only(ask for advice from an authorized reseller);
✔ Before starting the machine first check each time whether the charging hoses and the quick
couplers are undamaged and are not leaking;
✔ Recover refrigerant from the hoses before releasing the quick connections;
✔ Do not leave the unit unattended when switched on; Use the main switch to switch off the unit after
its use;
✔ Always wear personal safety equipment ( gloves and protective goggles);
✔ Avoid inhaling the refrigerating gas;
✔ Avoid the contact with the skin by refrigerating gas, danger of freezing;
✔ Never abandon the refrigerating gas in the environment;
of the refrigerant manufacturer;
✔ Do not use the unit in potentially explosive environments; (for instance: battery charging rooms);
✔ Do not smoke whilst using the recharging unit;
✔ During the operations, locate the unit on a flat and leveled surface;
✔ Do not use the unit near flames or sources of heat; at high temperatures the refrigerating gas can
generate poisonous substances for inhalation;
✔ Do not use the unit in very humid and wet environments or in the rain;
✔ Use the unit in airy environments;
✔ During maintenance operations disconnect the unit from the electrical power.
✔ Avoid removing the connecting hoses if not necessary; in case always make a vacuum in the
hoses before using again;

✔ Maintenance operations have to be carried out by specialized and authorized personnel.
✔ 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.
1.2.1 Warning icons used in the present manual
Caution! Connect to
230V socket
50Hz
1.2.2 Safety devices
A) Pressure release valves on internal gas tank: releases pressure if 16 Bar are exceeded in the gas tank.
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.
Wear gloves

carefully
- 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.

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
2.1.1
2.2 Preparing for use
2.2.1 Removal of load cell blocking device
Checking the accessories delivered with the unit
Before using the unit for the first time remove the safety screw which is screwed to the tank load
cell for protection during transport(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
Threaded hole to fix the calibration hook to the
2
load cell
3 Fixing bolts of the load cell
2.2.2 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)
Half of the level

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. The user has to
suction the gas residuals in the A/C system of the vehicle, at the en of the working cycle.
Note: in case of a pressure test which is not preceded by a standard working cycle, the user has to recover
the gas residuals in the vehicle A/C sytem, regardless to thehose length setting.
2.2.4 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.
2.2.5 Connecting to power feeding
Connect to proper power feeding according to the unit's technical specifications
2.2.6 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.
