ACM 150
Under these conditions you should close the external shut off valves:
• The system is shut down for an extended period, taken out of service or
relocated.
• The venturi pumps or gas cell are serviced.
• The utility external connections
disconnected.
CAUTION!
This is a high pressure safety hazard. The compressed air (CDA) supply
pressure normally exceeds 100 psig (7 kg/cm2). After shutting off the external
supply valve, check the internal pressure regulators on the CDA Panel,
20, to ensure that they read zero. This confirms that the pressure has bled
down and that it is safe to continue.
MISE EN GARDE!
Ceci est un risque de sécurité à haute pression . L'air comprimé ( CDA ) offre
pression dépasse normalement 100 psig ( 7 kg / cm2) . Après arrêt de l'
externe fournir vanne , vérifier les régulateurs de pression internes sur le
panneau de CDA , figure 20 , afin d'assurer qu'ils lisent zéro. Cela confirme
que la pression a saigné vers le bas et qu'il est sûr de continuer .
Internal disconnects
If you need to disconnect a specific assembly from line power to prevent it from
starting when power is restored, unplug it from the Power Distribution Panel,
19.
