Checking the safety valve
 If the maximum permissible operating pressure (10 bar) is exceeded in the pressure container, the
safety valve opens and ejects the excess air (at 11 bar) in order to protect the compressor and the
compressed air user attached to it.
 The safety valve must be bled occasionally in order to prevent the valve seat sticking.
 A defect safety valve has to be replaced completely.
 The compressor must be switched of thereby and the compressed air reservoir emptied.
Attention: Interventions in the controls are prohibited as such action cancels any liability.
Pressure container (accessory if requested)
 The condensed water that gathers in the pressure container must be drained off every day using
the condensed water drainage tap.
 Leaky pipe connections can lead to extensive loss of pressure.
 Occasional tightening of the pipe connections in necessary to prevent loss due to leakage.
Performance check
The effective performance of the compressor can be checked by measuring the compressed air reservoir
filling time:
 Switch off the compressor.
 Close the compressed air reservoir.
 Release container pressure using condensation drainage tag and then close it again.
 Switch on the compressor and simultaneously check the refill time until excess pressure and
compare it with the table.
Filling time in seconds (ca.) for 10-litre pressure container with the conditions of a constant
voltage. (1 V deviations are about 100 rpm)
