    Operation & Maintenance Manual Operating Instructions NOTE: As soon as the engine stops, the automatic blowdown valve will relieve all pressure from the system, except for the discharge pipe/ manifold area. This area should be depressurised by opening the discharge valve, keeping clear of any airflow from it. If the automatic blowdown valve fails to operate, then pressure must be relieved from the system by means of the service valve(s).
  • Page 55 Operating Instructions Operation & Maintenance Manual CAUTION To ensure an adequate flow of oil to the compressor at low temperature, never allow the discharge pressure to fall below 3,5 bar (50 psi). Decommissioning When the machine is to be permanently decommissioned or dismantled, it is important to ensure that all hazard risks are either eliminated or notified to the recipient of the machine.
