2. Safety
2.4 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 proper function, the instrument must be set up with
the following minimum clearance to walls and fixtures on all sides:
- rear: 15 cm - 5.9 inch
- right: 30 cm - 11.8 inch
- left: 15 cm - 5.9 inch
Electrical connection
• Before connecting the instrument to an AC power outlet, ensure that the
AC power of your laboratory matches the values on the nameplate of the
instrument.
• During the start-up of the refrigeration system, the minimum nominal
voltage must not drop below the values specified in Chapter 3, "Technical
Data".
The compressor draws a starting 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 stable power supply in accordance with the instrument's specifications
is essential to its proper functioning.
Failure to comply with the above can damage the instrument.
• 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 may cause damage to the instrument.
• No additional extension cable may be used.
Defrosting
• The quick freeze shelf can become very hot during the defrosting process.
Therefore, do not touch it!
