1. Scope of supply
The C 7520 chlorine changeover unit is supplied
as a plate-mounted unit ready for connection. When
unpacking, ensure that the enclosed wall mounting
material is not lost.
2. Installation
The preassembled chlorine changeover unit is
mounted on the wall using the screws and washers
supplied.
The installation location should be within easy reach
for the operating personnel so that the changeover
unit can be operated by hand if necessary. It should
not be exposed to direct sunlight or similarly bright
direct light, as this impairs the legibility of the
operating displays.
Installation example
2.1 Hydraulic installation
Important!
The chlorine changeover valve system is designed
for use in pressure-type chlorination installations
only! The changeover unit is resistant to pure, dry
chlorine (liquid or gaseous).
Important!
Connections must be carried out very carefully. Even
small leakages allow chlorine to enter the room
atmosphere and, together with air humidity, form
corrosive air.
The automatic chlorine changeover unit may
only be operated with two connected chlorine
gas batteries. If only one chlorine gas battery
is connected, the unused side must be tightly
closed.
Check for tightness using ammonia!
