5. Preparations
5.1. Installation
 Place the unit on an even surface on a base made of
nonflammable material.
 Cooling machine, pump motor and electronics produce intrinsic
heat that is dissipated via the venting openings.! Never cover
these openings!
 Be sure that the flow of ventilation can exit under the
instrument.
 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.
 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.
> For 0.25 kg of refrigerant R134a, 1 m
3
of space is required.
Model CF41 with 0.16 kg filling quantity of refrigerant R404A = 0,33 m

Model CF31 with 0.15 kg filling quantity of refrigerant R134a = 0.6 m

5.2. Temperature application to external systems
The Cryo-Compact Circulator is used for temperature application to external systems
(loop circuit)
Caution: Securely attach all tubing to prevent slipping.
Notice: Flood hazard!
If the liquid levels in the Cryo-Compact Circulator bath and the external system are at
different heights, overflowing must be prevented after the power has been turned off.
