the associated dangers. Otherwise, there is a danger of operat-
ing errors and injuries.
Supervise children during use, cleaning and maintenance. This
will ensure that children do not play with the device.
The equipment must only be operated by qualified specialized
staff!
What to do in the event of accidents or disruptions in the refrigerating system
Danger: Please comply in full with the following safety
information in order to exclude personal injuries!
Shutting down in emergencies
 Shutting down in emergencies
Pulling out the plug
Switching off the fuse
Refrigeration cycle intervention
 Only allowed by refrigeration technical experts. Contact customer service.
 Take care in the event of accumulation of cooling agent vapours at ground level – lack of
oxygen – risk of suffocation!
 Smoking and unshielded flames prohibited!
 Always ensure the power is off in the system before intervention (see above)!
First aid
 Use protective goggles to shield your eyes against exposure to liquid cooling agents!
In the event of eye contact with liquid cooling agent do not rub the eyes and avoid all eye aggra-
vation. Consult a physician immediately.
 First aid: Apply a few drops of sterile mineral oil to the eyes or a weak boric acid solution or
2% common salt solution. Subsequently rinse out eyes.
Attention: Please comply in full with the following safety
information in order to exclude the danger of property dam-
age and damage to the environment!
Disruptions
If the refrigerating system fails to operate
 check whether the current entry has been interrupted. This calls for troubleshooting by tech-
nical experts!
If both refrigerating clamps fail to ice over
 check whether the refrigerating machine is running and if the condenser is being aerated
adequately (is not contaminated, ventilation slots not displaced). If this should be the case,
troubleshooting needs to be carried out by a technical expert (cooling device constructor, re-
frigeration technician)!
If only one of the refrigerating clamps ices over
 hold both refrigerating clamps upright for about 10 minutes while the machine is running so
that any process oil that may have become displaced in the refrigerating clamps drains back
to the compressor. If this does not lead to a change, a technical expert should be asked to
carry out troubleshooting.
If the refrigerating system shuts down for no recognisable reason this could be due to
 unduly high process temperatures or electric currents as a result of excessively high or low
ambient temperatures
 inadequate air flow (air grille displaced, condenser contaminated)
 electric failure.
