Safety
Each time you start up the unit or top up the A/CServiceCenter, first
check whether the unit and all the service hoses are undamaged and that
all valves are closed.
Always position the unit on level ground and secure the front wheels.
Only use approved refrigerant vessels with safety valves to refill the
A/CServiceCenter.
Drain the service hoses before you undo the connections.
Only use R-1234yf refrigerant. If other refrigerants are mixed in, this can
damage the A/CServiceCenter and the vehicle air conditioning system.
Only use WAECO UV additive. If you use other UV additives, it could
cause damage to the A/CServiceCenter. This will invalidate any war-
ranty.
Before you shut down the A/CServiceCenter, make sure that the
selected programme has ended and that all valves are shut. Otherwise
refrigerant can leak.
Always use the main switch of the A/CServiceCenter to switch it on and
off. Do not leave the unit unattended when it is switched on.
Maintenance and repairs to the unit may only be performed by qualified
and approved personnel from suitable and certified specialist companies.
Do not pump compressed air into the refrigerant lines of the
A/CServiceCenter 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
displaces the oxygen you need to breathe.
