5.3 Installation of units
5.3.1 Installation of vacuum regulator
The chlorine cylinders must be secured by wall holders when being stand up. Before connecting the units,
the cylinders should have reached room temperature and the cylinder contents must have calmed down after
transportation. When using chlorine drums make sure that the marking of the drum is in horizontal position
(see information of the manufacturer). For a supply of gaseous chlorine the upper connection is used (see
„Comments regarding chlorine drums“ on page 14).
The vacuum regulators are either mounted directly on the chlorine cylinder valve or on the wall holder. For
cylinder mounted vacuum regulators a PVC wall connector is mounted above the chlorine cylinder. At this the
vacuum regulator will be mounted during the cylinder changing and the regulator connection is protected of
incomming humanity. The connection sealings made of special PTFE must not be greased with silicone grease.
These sealings must also only be used once. The union nut for connecting the cylinder is tightended gently and
the unit is secured against distorsion using a secowrench.

The flow meter is in vertical position with the dosing connector at the top.
The blowoff connection of the safety valve is also carried out as tubing connection. The connected tubing
should end close to the gas sensor so that in the case of malfunction an alarm can be be released immedi-
ately. The integration of an activated-carbon cartridge at the outlet of the safety valve avoids faulty alarms
resulting from system-related temporary shock pressures.
It is quite reasonable to run the blowoff connection close to the gas sensor so that in the case of malfunction
an alarm signal can be released immediately. The integration of an activated-carbon cartridge at the outlet of
the safety blowdown valve avoids faulty alarms resulting from system-related temporary shock pressures. It is
advisable to use a PVC tubing for connecting the active-carbon cartridge. As soon as a chlorine contact occurs
the appearance of the tubing changes from transparent to milky thus signalling a leakage.
