10.3 Refrigerant
NOTE
The air conditioning system is operated with
the refrigerant R134a (tetrafluoro-ethane).
This substance does not contain any chlo-
rine atoms and is thus harmless for the
ozone in the atmosphere.
The refrigerant must not simply be drained
off, bust must be professionally disposed
of. Connecting lines must therefore not be
disconnected. Have maintenance and repair
work on the air conditioning system solely
carried out by your HORSCH sales partner
using appropriate disposal and recycling
facilities.

10.4 Collector / dryer
NOTE
The ambient temperature must be higher than
the temperature set on the thermostat (nor-
mally +1 °C) so that the compressor will cut in.
Since the refrigerant collector is under operating
pressure, it is subject to the Pressure Vessel
Ordinance with respect to manufacturing and
testing.
In this ordinance the pressure vessels are clas-
sified in test group II in accordance with their
operating pressure p in bar, their volumetric
capacity l in litres and the pressure contents
product p x l.
According to § 10 of the Pressure Vessel Ordi-
nance, these pressure vessels must be subject-
ed to repetitive testing by an expert as per § 32.
Repetitive tests in this case consist of external
examinations, normally on vessels in opera-
tion. The refrigerant collector is to be visually
examined two times per year in connection with
the inspections. Special attention must thereby
be paid to corrosion and mechanical damage.
Should the tank not be in a fit state, it must be
replaced because of safety related reasons, as
a precautionary measure for the owner and third
parties, because of the dangers related with the
handling and operation of pressure vessels.
