protective caps and harm the operator.
,
WARNING!
During installation, pay maximum attention that the suction
flange is connected to the vacuum chamber and the exhaust
flange is not closed (see the following figure).
The pump must not be used as a compressor.
Maximum pressure inside the oil container must not exceed 1.5
bar (abs.)
Non-observance of these precautions may be dangerous for
