Symbol Warning to prevent injuries
FLEXIBLE HOSES MAY CONTAIN LIQUID
REFRIGERANT UNDER PRESSURE. Contact with
the refrigerant can cause injury, blindness and
skin freezing. Wear protective clothing that include
safety glasses and gloves. Disconnect the hoses
with extreme caution. Make sure that the step has
been completed before disconnecting the station,
to avoid refrigerant emissions in the atmosphere.
DO NOT INHALE REFRIGERANT OR LUBRICANT IN
THE FORM OF STEAM OR SPRAYED The refrigerant
R1234yf reduces the amount of oxygen available
for breathing, causing drowsiness and dizziness.
Exposure to high concentrations of R1234yf causes
asphyxia, ocular, nose, throat and lungs lesions
and may harm the central nervous system. Use
the station in places where there is a mechanical
ventilation system that completes the air exchange
at least once per hour. If accidental spillage from
the system occurs, ventilate the work area before
resuming operations.
DO NOT DISPERSE THE REFRIGERANT IN THE
ENVIRONMENT. This precaution is necessary to
prevent the presence of refrigerant in the working
environment.
The refrigerant R1234yf is heavier than air and
tends to concentrate in the pits of the workshop.
TO REDUCE THE RISK OF FIRE, do not use the
machine near petrol containers or other flammable
liquids or near any point where one of these
substances has been spilled.
TO REDUCE THE RISK OF FIRE, do not use an
extension, as it may overheat and cause a fire. If it
is necessary to use an extension, make it as short
as possible and with a section of at least 14 AWG.
TO REDUCE THE RISK OF FIRE, do not use the
machine near flames and high temperature
surfaces. Refrigerant can decompose at high
temperatures and emit toxic substances in the
environment that may be harmful to the user.
TO REDUCE THE RISK OF FIRE, do not use the
machine in environments containing explosive
gases or vapors.
TO REDUCE THE RISK OF FIRE, do not use the
machine in areas or zones with ATEX classification.
Protect it from conditions that could cause
electrical failure or other hazards related to the
interaction with the environment.
DO NOT USE COMPRESSED AIR TO SUBMIT
THE VEHICLE MACHINE OR A/C SYSTEM TO A
PRESSURE OR LEAK TEST. Air and refrigerant
mixtures R1234yf can be high-pressure
combustible materials; they are potentially
dangerous and can cause a fire or an explosion
and therefore accident or damage to property.
HIGH VOLTAGE IN THE MACHINE; RISK OF
ELECTROCUTION. Exposure can cause injuries;
disconnect the power supply before performing
any maintenance or repairs to the machine.
NEVER LEAVE THE MACHINE ENERGIZED IF IT
MUST NOT BE USED INTERMEDIATELY. Disconnect
the power supply before long periods of inactivity
or before performing internal maintenance. To
ensure that unauthorized personnel can not
operate the machine, use the function that allows
to padlock the main power switch.

i
To minimize the risk of fire, the station software
periodically performs a guided leak check
otherwise the station stops. For the same purpose,
there are also hardware features such as ventilation
fan monitoring system, openings properly located
on the bottom of the trolley (R1234yf is heavier
than air) and sealed electronic circuits.
Symbol Caution to prevent damage to the equipment
TO PREVENT CROSS CONTAMINATION, USE THIS
MACHINE ONLY WITH THE REFRIGERANT R1234yf.
The machine is equipped with special fittings for
recovery, recycling and refilling of the refrigerant
R1234yf. Do not attempt to adapt it for use with
another refrigerant. Do not mix different types
of refrigerant through a plant or in the same
container; it would cause serious damage to the
station and to the A/C system of the vehicle.
Do not use refrigerants other than those
indicated on the technical data plate. It is also
recommended to buy it at specialized companies
that guarantee its good quality.
DO NOT USE THE STATION OUTDOOR IN CASE
OF RAIN OR HIGH HUMIDITY. Protect it from
conditions that could cause electrical failure or
other hazards related to the interaction with the
environment.
DO NOT USE THE STATION AT DIRECT SOLAR
LIGHT. Place the machine away from heat sources
such as direct sunlight, which may cause excessive
temperatures.
Using the machine under normal environmental
conditions (10 to 50 °C) keeps pressures under
reasonable limits.
Make sure that the machine does not exceed the
operating temperature indicated on the technical
data plate.
DO NOT USE THE STATION IN AREAS IN WHICH
THERE IS THE RISK OF EXPLOSION.
Place the station on a flat surface and in sufficient
lighting conditions; lock the front wheels and do
not subject them to vibration.
For more information on safety and health protection,
contact the refrigerant manufacturer.
WARNING: Warranty is not valid in all cases
of improper use of the machine and if the
machine is not submitted to periodic ordinary
and extraordinary maintenance (according
to PED directive 2014/68/EU) provided in
this original instructions. The manufacturer
therefore declines all responsibilities for
any damage resulting from not observing
all the instructions and warnings provided
to the user regarding installation, use and
maintenance.
