5. Preparations
5.1. Installation
 Place the unit on an even surface on a pad made of non-flammable
material.
 Press down the castor levers on model FT900.
 The instrument should be set up at a frost-proof and dry 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: 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.
> For 0.25 kg of refrigerant R134a, 1 m
3
of space is required.
> For 0.52 kg of refrigerant R404A, 1 m
3
of space is required.
> For 0.68 kg of refrigerant R23, 1 m
3
of space is required.
 The ambient temperature must not exceed 35 °C.
 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. Immersion Probe
Avoid touching the immersion probe if it is frosted.
DANGER OF INJURY. Use gloves.
Switch the unit on only if the probe is immersed into the bath fluid.
To prevent the immersion probe (A) from icing, it should be completely
immersed into the bath liquid (B).
