ED
5. Preparations
5.1. Installation
•
Place the unit on an even surface on a pad made of
non-flammable
material.
•
Set selector dial for cooling machine (16) in position
"0" for operation with ED circulator. (only F25, F26)
•
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 radiates to the environment.
(Max. permissible ambient temperature: 40 °C).
With regard to a disturbance in the cooling loop
(leakage), the guideline EN 378 prescribes a certain
room space to be available for each kg of
refrigerant.
The necessary amount of refrigerant is specified on
the type plate.
> For 0.25 kg of refrigerant R134a, a room space of
1 m
3
is required.
