6 Check that the float rests on the bottom stop of the flowmeter.
Any movement of the float indicates an ingress of air on one of
the following locations:
• through the pressure relief valve
• through the 'O' ring on the bottom of the flowmeter
• through cracks in the flowmeter
• through the 'O'-rings at the pipe connections
• through any incorrectly cemented joints or slack unions in
the pipework.
7 Repair all leaks before going any further.
4.11.4 Check for gas leaks
Warning!
Chlorine gas irritates the respiratory tracts. Contact with chlorine
gas in high concentrations irritates and damages the membranes,
respiratory system and the skin. In extreme cases death can result
due to suffocation.
The same applies to sulphur dioxide.
When inspecting the system for leakage always keep your gas
mask to hand. Practice use of the mask regularly.
If chlorine gas is discharged, only use a gas mask which is inde-
pendent of circulating air!
In case of carbon dioxide care for sufficient fresh air.
Do not tolerate any leakages in the chlorine system.
Before servicing the system the gas supply must be closed off di-
rectly on the gas cylinders or tank and the chlorine gas in the sys-
tem must be consumed completely.
In case of strong chlorine smell put on your gas mask.
Note
Testing for chlorine (or SO2) gas leaks is accomplished by intro-
ducing ammonia fumes to the area under test. Any escaping gas
will combine with the ammonia to form dense white clouds of am-
monium chloride. Liquid ammonia solution must not be applied di-
rectly to the part being tested. Hold a bottle of 25% ammonia
solution in the vicinity of the part under test.
Ammonia must not be inhaled, splashed, or spilled.
When testing for CO2 use e.g. leak spray.
