Procedure for preparing the control air system for operation

This procedure assumes that all valves are initially closed and that air must be supplied from the operating air system.
a)      Make sure that the valves of all control devices are open.
b)     Switch the valves as shown in figure below.

Example of a control air system commissioning procedure

a)      Open the individual inlet valves for all control systems.
b)      Connect the control air dryer.

NOTE: It will take some time for the full drying effect to occur. Initially, release the supplied compressed air into the atmosphere until dry, moisture-free air is available to the control air system.
The air control system is now operational and ready for use.
