7.6 Installation with bypass
The volume to be removed from a supply battery is limited by the number
of pressure tanks connected. To prevent the unnecessary connection of
too many pressure tanks, in the majority of cases, the supply battery is
designed for normal operation. Such installations are fitted with a bypass
valve for higher volumes required at short notice (e.g. a shock chlorina-
tion). It is thus possible to extract from both supply batteries simultane-
ously.

If the dosing system is also to be operated whilst maintenance is per-
formed on the changeover unit, 5 manual valves are required in the pipe
line.
