4. Installation
 Place the unit on an even surface on a base made of
nonflammable material. Using the castors (10a, 10b) move the unit
to the intended location.
For better stability, apply the holding breaks on the front casters
(10a).
 Cooling machine, pump motor and electronics produce intrinsic
heat that is dissipated via the venting openings! Never cover these
openings!
 Do not set up the unit in the immediate vicinity of heat sources and
do not expose to sun light.
 Keep at least 20 cm of open space on the front and rear venting
grid.
 The place of installation should be large enough and provide
sufficient air ventilation to ensure the room does not warm up
excessively because of the heat the instrument rejects to the
environment.
For a fault (leakage) in the refrigeration system, the standard EN
378 prescribes a certain room space to be available for each kg of
refrigerant.
> For 0.52 kg of refrigerant R-404A, 1 m3 of space is required.
