5. Preparations
5.1. Installation
 Place the unit on an even surface on a pad made of non-
flammable material.
 The circulator fitted with a stainless steel bridge is placed on on
the back of the bath tank leaving the bath open on the front side.
 Using the castors move the unit to the intended location.
 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.
 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.
5.2. Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid used, particularly with
regard to the fire point!
If a bath fluid with a fire point of
65 °C is used, only supervised operation is
possible.
Water:
The quality of water depends on local conditions.
 Due to the high concentration of lime, hard water is not suitable for
temperature control because it leads to calcification in the bath.
 Ferrous water can cause corrosion - even on stainless steel.
 Chloric water can cause pitting corrosion.
 Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.
