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 re-
turn into its original position. Furthermore, any condensation that has formed during this time
due to temperature fluctuations must be allowed to dry completely.
Failure to comply with this can cause severe damage to the instrument!

Failure to comply with this can cause severe damage to the instrument!
During the start-up of the compressor the nominal voltage must not drop below the values
specified in the "Technical Data".
Please note that the compressor requires a start-up current between 25 and 35 A.
Therefore, the electric circuit at the installation site must be inspected by an electrical
engineer to ensure that it meets the requirements for a smooth operation of the instrument.
Failure to comply with the above will cause severe damage to the instrument!
