Testing Mobrey`s
Float operated switches.
Starting with the dual Mobrey turn the sequencing valve handle in a clockwise direction until the halfway mark and pause for the count of Ten, the alarm should sound at this point. Then continue turning the handle until the valve is fully open, again pausing for the count of Ten. The Mobrey should now be completely drained with the alarm sounding continously. Now proceed to turn the handle in an anti-clockwise direction until you reach the halfway mark once more pausing for the count of Ten. Now proceed further until the valve is back at the operating position. The alarm should stop sounding at this point. The Mobrey is now in its operating position.
Should the alarm not sound? Call an Electrician immediately.
Should the alarm continue sounding after testing the Mobrey? Call an Electrician immediately.
Next we proceed to the single Mobrey, turn the sequencing valve handle in a clockwise direction until the halfway mark and pausing for the count of Ten, at this point the I D Fan, F D Fan/s and stokers should trip out. Now continue turning the handle in a clockwise direction until the valve is fully open, again pausing for the count of Ten. Then proceed to turn the sequencing valve handle in an anti-clockwise direction until the halfway mark is reached, pausing again for the count of Ten. Proceed to turn the sequencing valve handle in an anti-clockwise direction until the valve is back at the operating position.
At this point the boiler can be restarted making sure that the dampers are closed before starting the I D Fan.
Should the boiler fail to stop? Call an Electrician immediately.Should the boiler fail to start? Call an Electrician immediately and bank the boiler if necessary. Should the Mobreys fail to work,Stop the boiler immediately and bank the boiler until the problem is rectified

If the question says, explain how to blow down the mobrey controls. Does this satisfy the question?
