5.3. Installation
Caution:
Danger of tipping
 Lift the unit only with a crane using the lifting strands and the wooden crate (see
pictures on page 2)
 The recessed grips on the side are not suited for lifting the unit!
Careful positioning of the unit on its rollers is permitted.
 Max. permissible application of force to the upper side 220 N.
Danger of tipping if larger force is applied.
 The unit is not suitable for use in explosive environment
 Place the unit on an even surface on a base made of
nonflammable material. Lift the handle (6) and using the
castor (19) move the unit to the intended location.
 Keep at least 20 cm of open space on the front and rear
venting grids.
 Do not install the unit in the immediate vicinity of heat
sources and do not expose it to sunlight.
 Before operating the unit after transport, wait about one
hour after setting it up. This will allow any oil that has
accumulated laterally during transport to flow back down
thus ensuring maximum cooling performance of the
compressor.
 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. (Max. permissible
ambient temperature: 40 °C).
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.
The refrigerant quantity is specified on the type plate.
> For 0.52 kg of refrigerant R404A, 1 m
3 of space is
required.
5.4. Connect the external system
The temperature systems are designed for temperature
application to closed, external systems (loop circuits). To profit
from the system's rapid performance, ensure the tubing line
between the temperature system and the connected external
system is as short as only possible.
