 Place the unit in an upright position.
 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.
> For 0.25 kg of refrigerant R134a, 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 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.
 Connect the tubings for cooling the external system to the
pump connectors for feed and return (12.1. and 12.2.) on
the rear of the recirculating cooler.
Return flow safety device see page 18
 If necessary, connect a tube to the overflow port (13.) for
controlled draining of the liquid.
Do not close the overflow port.
 Only for water cooled models:
Ensure circulation of cooling water by connecting the
tubing to cooling water inlet (16.2.) and outlet (16.1) on the
rear of the recirculating cooler.
Cooling water temperature: <20 °C
Quality of cooling water see page 11.
Caution:
Securely attach all tubing to prevent slipping.
