Heating/ventilation/air-conditioning
Safety instructions for the air-conditioning system
Safety instructions for the air-
conditioning system
Air-conditioning systems that are op-
erated with refrigerant R 134 a are la-
belled with appropriate stickers and/or
plates on the compressor.
Never mix R 134 a refrigerant and the
corresponding DEA Triton SE 55 refriger-
ator oil with other products.
It is forbidden to disregard the latest
technological standards and allow refri-
gerant to escape into the environment
when servicing or decommissioning air-
conditioning systems.
Refrigerant and refrigerator oils must be
disposed of separately, or recycled.
Maintenance work on air-conditioning
systems as well as removal of refriger-
ants and oils may only be carried out by
persons who have the relevant and ne-
cessary specialist knowledge, technical
equipment and official approval (control
of health and safety at work, local gov-
ernment, TÜV).
The operator must maintain a logbook
auditing the consumption of refrigerant
and refrigerator oils.
Danger.
On automatically controlled air-condition-
ing systems, the ventilation blowers can
be started at any time by the condens-
er or evaporator units. Therefore turn the
ignition switch to the OFF position when
carrying out cleaning work. Do not reach
into the fan blades or fan rollers. Avoid
any contact with refrigerant as there is
a risk of frostbite. Treat affected skin
areas as for frostbite, and contact a doc-
tor straight away. Carry out maintenance
and repair tasks with the engine switched
off whenever possible. Keep a safe dis-
tance from moving parts (e.g. belt drive)
when the engine is running.
Operating instructions for the air-
conditioning system
Note:
The driver's window should remain closed
while the vehicle is in motion and the
air-conditioning is operating to ensure
faultless operation of the air-conditioning
system.
