2. Safety
2.3 Operating conditions
Transport and installation
• After transporting do not turn the instrument on for a minimum of 4 hours!
• Do not operate in rooms with explosion hazard!
• To ensure an adequate cooling capacity, the instrument must be set up
with at least 10 cm distance from walls and furniture!
Connection to mains
• Before connecting to the mains power, please check if the local voltage
complies with the power rating specified on the name plate of the instru-
ment!
• During the compressor start-up the nominal voltage must not drop be-
low the values specified in the ‘Technical data‘!
The compressor requires a start-up current between 45 and 50 A.
Therefore, the electric circuit at the place of installation must be inspected
by an electrical engineer to ensure that it meets the requirements for a
smooth operation of the instrument.
A constant adequate power supply to the instrument must be ensured at
all times.
Failure to comply with the above will cause severe damage to the instru-
ment.
• After transporting, wait at least 4 hours before turning the instrument on.
This waiting period is necessary to allow the compressor oil, which may
have been displaced during transport, to return to its original position.
Failure to comply with this can cause severe damage to the instrument.
Defrosting
• The quick freeze shelf may become hot during defrosting!
Therefore, do not touch it!
2.4 Operating the instrument
• Take care when handling microtome knives and disposable blades. The
cutting edge is extremely sharp and can cause severe injury!
