5.1 Operating personnel
The constant climate chamber may only be operated by persons who are of legal age, and
who have received instructions for the constant climate chamber. Personnel who are to be
trained, instructed or who are undergoing general training may only work with the constant
climate chamber under the continuous supervision of an experienced person.

5.3 Loading the constant climate chamber
Warning
When loading the chamber with an
unsuitable load, poisonous or explosive
vapours or gases may be produced. This
could cause the chamber to explode, and
people could be badly injured or poi-
soned. The chamber may only be loaded with materials/test objects
which do not form any toxic or explosive vapours when heated up
and cannot ignite (see also chapter " Intended use " on page 12 ). If
there is any doubt as to the composition of materials, they must not
be loaded into the constant climate chamber.
Caution:
Check the chamber load for chemical compatibility with the materials of the constant
climate chamber (see page 12 ).
Replacing sliding shelf/shelves. The maximum quantity, and load capacity of the sliding shelves
can be found in table in chapter " Technical data " on page 14 .
The chamber must not be
loaded too tightly, so that
proper air circulation in the
working chamber is guaran-
teed. Do not place any of the
chamber load on the floor,
touching the side walls or
right below the ceiling of the
working chamber ( Fig. 13 , see
also the "correct loading"
sticker on the appliance).
If the load is unfavourable
(too close together) it may
take longer than normal to
reach the set temperature
under some circumstances.
