2.3Safety instructions: handling and operation of the instrument

2.3.1 Transport

•To avoid severe damage to the instrument by running it while the compressor oil is dis- placed from its regular position:

•Do not tilt the instrument,

only transport in an upright position.

•After transport, wait at least 4 hours be-

fore turning the instrument on.

-->The compressor oil may have been displaced during transport and must settle to its original position be- fore switchingthe instrument on. Otherwise, the instrument may be severely damaged.

2.3.2 Site requirements

•Do not operate the instrument in rooms with explosion hazard.

•To ensure proper instrument function main- tain a minimum distance of 10 cm between walls and/or furniture and all sides of the in- strument!

2.3.3 Electrical connections

•Do not use extension cords for connecting the instrument to mains.

-->Fire hazard!

-->Instrument malfunctions caused by voltage drop.

•During the start-up phase of the compressor, the nominal voltage must not drop below the values specified in chapter 4.2 ‘Technical data’!

-->The compressor needs a start-up current at between 25 and 35 A (see chapter 4.2 ‘Technical data’)

•Ensure uniform current supply according to specifications.

-->Electrical power supply deviating from specifications damages the instrument.

•Therefore, arrange for the electrical in- stallations on site to be checked by a trained professional and make sure any necessary upgrades are installed!

•Have the circuit protected by a fuse of its own!

•Do not connect any other consumers to the same circuit.

•Prior to connecting the instrument to mains, make sure the electrical power supply in your laboratory corresponds to the values indicated on the instrument nameplate (located at the rear of the in- strument)!
