CAUTION! Failure to obey these cautions could result in minor or moderate injury.
• Do not start up the A/C service unit if it is damaged.
• Each time you start up or top up the A/C service unit, first check whether the A/C service unit and all
the service hoses are undamaged and that all valves are closed.
• Lay the service hoses in such a way that they pose no tripping hazard for other persons.
• Serious injuries due to overturning or falling load: The handle is not used to lift the A/C service unit.
Only push the A/C service unit on rollers to transport it.
• Always position the A/C service unit on level ground and secure the front wheels.
• Only use approved refrigerant vessels with safety valves to refill the A/C service unit.
• Always use the main switch of the A/C service unit to switch it on and off. Do not leave the device un-
attended when it is switched on.
• Risk of injury from leaking fluids: Leaking fluids on the floor can cause persons to slip and injure them-
selves. Wipe up leaked or dripped fluids immediately or absorb them with a suitable binding agent.
Dispose of them in an environmentally sound manner.
NOTICE! Indicates a situation that, if not avoided, can result in property damage.
• Never expose the A/C service unit to heavy moisture.
• Do not operate the A/C service unit outdoors when it is raining.
• Do not operate the A/C service unit near heat sources (such as heaters) or in direct sunlight.
• Only use the refrigerant that you have set in the A/C service unit. If other refrigerants are mixed in, this
can damage the A/C service unit and the vehicle air conditioning system.
• Before you shut down the A/C service unit, make sure that the selected program has ended and that
all valves are shut. Otherwise refrigerant can leak.
• When you modify values in the menus, always compare them with the specifications on the vehicle.
• When parking, use the brake lever on the front wheels to secure the A/C service unit from rolling away.
6.2 Handling the refrigerant safely
WARNING! Failure to obey these warnings could result in death or serious injury. Do not carry out
maintenance work on the vehicle air conditioning system when the engine is at operating temperature.
When performing maintenance on the vehicle air conditioner, the surface temperature of attachment parts
or surrounding parts must be less than the refrigerant's flashpoint:
R1234yf: 405 °C
R134a: 743 °C
R153A: not applicable
CAUTION! Failure to obey these cautions could result in minor or moderate injury.
• Wear personal safety equipment (safety goggles and protective gloves) and avoid coming into con-
tact with the refrigerant. Contact with the refrigerant draws out body heat and the affected areas can
freeze.
• Do not inhale refrigerant vapor. Although the vapor is non-toxic, it displaces the oxygen you need to
breathe.
• Only use the device in well-ventilated areas.
• Refrigerant may not be used in low-lying spaces such as assembly pits or soakaways. Refrigerant is
heavier than oxygen and therefore displaces the air you need to breathe. This can cause a lack of oxy-
gen when working in unventilated assembly pits.
NOTICE! Indicates a situation that, if not avoided, can result in property damage.
• Make sure that refrigerant is not able to escape and leak into the environment during operation, when
filling or draining refrigerant or during repair and service work. This will protect the environment. It also
avoids the difficulty or impossibility of detecting leaks in the vehicle or in the A/C service unit due to the
presence of refrigerant in the vicinity of the A/C service unit.
• Take suitable precautions to ensure that leaking refrigerant is not able to get into the drainage system.
Note Supplementary information for operating the product. Special information on the refrigerant and
safety measures as well as the protection of personnel and objects, including fire protection, can be found
in the safety sheets of the refrigerant manufacturer.
