On c) Distribution system / dosing lines for chloride solution
The whole distribution system for the chloride solution is installed on the feed
system and ready for use.
The dosing lines consist of the following components:
63.
Membrane valves or dosing ball valves for setting the flow or dosing performance
required (1)
64.
Flow meter to indicate the flow performance (1)
65.
pH monitoring (option)
66.
Solenoid valves controlled by measuring and control equipment for free chlorine
67.
Ball valves
68.
Screw connection of the feed pump
The flow performance required is determined from the chlorine concentration in
the solution and the required dosing performance regarding free chlorine. See
Section 5.2.11,
Dosing performance assessment = Nominal performance of the
granulate dosing at the initial operation
A relay system separates the power supply to the control valves, when the feed
pump is switched off due to a fault message in the GRANUDOS system. This causes
the control valves to close. The dosing lines must be equipped with reflux valves
provided by the customer to prevent reflux from the swimming pool into the buffer
tank (in case a control valve does not fully close).
ATTENTION !
Ball reflux valves must in all cases be installed in dosing lines by the
customer to provide additional protection!
