7. Operation
7.1 Start up
Normal startup of the compressor/vacuum pump (referred to in the following text as the “machine”) is carried out as described in
section 0 .
7.2 Regular Checks
During Compression Operation
Check operating pressure on the manometer (see rating plate on the machine for the permissible pressure).
During Suction Operation
Check the operating vacuum on the vacuum meter (see rating plate on the machine for the permissible vacuum).
Final Compression Temperature
The final compression temperatures are approximately:
Drain Condensate
Drain condensate from the condensate and safety tanks.
Rotation Speed
Check the permissible rotation speed.
Oil Level
Check the oil level by observing the oil tank.
If the oil level reaches the minimum mark on the tank bracket, add more lubricating oil.
For the lubricating oil specification, see section 6.7 .
7.2.1 Safety Valve
A non-lockable safety valve must be installed in the pressure line after every compressor. It must be set so that the highest
permissible operating pressure cannot be exceeded by more than 10%.
The setting of the valve must be safeguarded against unauthorised or erroneous alteration.
The safety valve must not be blocked, or otherwise manipulated in any way.
Avoid expelling the entire volume via the safety valve when the pressure line is closed, as doing so may cause harmful pressure
pulses.
The safety valve must not be used as a pressure regulation device!
Check the valve for proper functioning upon initial startup, and thereafter once a week, by activating the manual
ventilation while the machine is running.
