Handling Refrigerant Safely - Waeco AirConServiceCenter BMW5500G RPA Operating Manual

Safety
 Only use R-1234yf refrigerant. If other refrigerants are mixed in, this
can damage the AirConServiceCenter and the vehicle air condition-
ing system.
 Before you shut down the AirConServiceCenter, 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
AirConServiceCenter from rolling away.

Handling refrigerant safely

!
WARNING!
 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 405 °C.
!
CAUTION!
 Wear personal safety equipment (safety goggles and protective
gloves) and avoid coming into contact 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.
A
NOTICE!
 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 unit due to the presence of refrigerant in the vicinity
of the AirConServiceCenter.
 Take suitable precautions to ensure that leaking refrigerant is not able
to get into the drainage system.
