Cleaning the vacuum demand valve
Every year clean the vacuum demand valve. The standard and au-
tomatic switchover units are both cleaned in the same manner.
Warning!
To avoid possible severe personal injury or equipment damage,
shut the gas supply container valve; evacuate all gas from the sys-
tem and release any pressure in the solution discharge line as de-
tailed in Section 5.2.2.
Warning!
Any vertical section of the vent tube may contain chlorine gas/con-
densate.
Pinch the vent tube at its lowest point and then disconnect it from
the demand valve.
Remove and plug the open end. If necessary clear the vent tube
by blowing through it using an inert gas, or allow tube to drain/vent
into room under controlled conditions.
Refer to the drawing in chapter 7.3
