5. Preparations
5.1. Installation
 Place the unit in an upright position.
For better stability, apply the holding brakes on the front casters.
 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: 35 °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.
 Keep at least 20 cm of open space on the front and rear venting
grids.
 Do not set up the unit in the immediate vicinity of heat sources
and do not expose to sun light
 Before operating the unit after transport, wait about one hour after
installation. This will allow any oil that has accumulated laterally
during transport to flow back down, thus ensuring that the
compressor can develop its maximum capacity.
Recommendation:
Before filling please install a drain cock at the discharge nozzle. (25)
