Vacuum Regulator for Chlorine Gas C 2700-V Operating Instructions
BA-21210-02-V05
6.3.3 Safety valve
The blow-off line is a tube whose open end should be located in the
vicinity of the gas sensor. The installation of an activated carbon
cartridge is recommended at the open end of the tube which prevents
an alarm being issued in the event of system-related short shock pres-
sures.

"Inspecting the vacuum system" on page 19).
Item Description
1 Vacuum regulator
2 Blow-off line
3 Activated carbon cartridge
4 Gas sensor
A transparent PVC tube is ideal as a blow-off line. It becomes
milky in appearance when it comes into contact with chlorine
for the first time and thus allows faults to be detected early
on.

All the exposed bare metal surfaces must be painted as the
atmosphere in chlorine gas rooms is highly corrosive. A two-
part epoxy resin varnish yellow RAL1003 is suitable for
example. The surfaces must not be painted until after
successful completion of the leak test.
