AirConServiceCenter Safety
Each time you start up the device or top up the AirConServiceCenter,
first check whether the device and all the service hoses are undamaged
and that all valves are closed.
Only used approved refrigerant bottles with safety valves to refill the
AirConServiceCenter.
Drain the service hoses before you release connections.
Only use R-134a refrigerant. If other refrigerants are mixed in, it can dam-
age the AirConServiceCenter and the vehicle air conditioning system.
Only use WAECO UV additive. If you use other UV additives, it can dam-
age the AirConServiceCenter.
Before you shut down the AirConServiceCenter, make sure that the
selected program has ended and that all valves are shut. Otherwise
refrigerant can leak.
Always use the main switch of the AirConServiceCenter to switch the sta-
tion on and off. Do not leave the device unattended when it is switched
on.
Do not pump compressed air in the refrigerant lines of the
AirConServiceCenter or the vehicle air conditioning system. A mixture
of compressed air and refrigerant can be flammable or explosive.
2.3 Handling refrigerant safely
Maintenance must not be carried out on the vehicle air conditioner 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
405 °C.
Wear personal safety equipment (safety goggles and protective gloves)
and avoid coming into contact with the refrigerant. Contact with the refrig-
erant draws out body heat and the affected areas can freeze.
Make sure that refrigerant is not able to escape and leak into the environ-
ment during operation, when filling or draining refrigerant or during repair
and service work.
This adheres to environmental protection laws. It also avoids the difficulty
or impossibility of detecting leaks in the vehicle or in the unit due to the
presence of refrigerant in the vicinity of the unit.
Do not inhale refrigerant vapour. Although the vapour is non-toxic, it dis-
places the oxygen you need to breathe.
Refrigerant must not be used in low-lying spaces such as assembly pits
or soakaways. Refrigerant is heavier than oxygen and therefore dis-
places the air you need to breathe. This can cause a lack of oxygen when
working in unventilated assembly pits.
