Ambient conditions
4.3.1 Installation site
The following points must be taken into
account when installing flow cell:
•
The flow cell must be protected from
moisture, rain, frost, heat and direct sun-
light and must not be installed outdoors.
•
Do not use the flow cell in environments
where there are flammable gases, fumes
or dust or conductive dust.
•
Do not subject the flow cell to strong
shocks or vibrations.
•
The air in the room should be non-con-
densing.
4.3.2 Installation location for drinking
water, industrial water and waste
water
For problem-free mixing of the chlorine solu-
tion, the distance between chlorine addition
and sample water take-off must be at least ten
times the pipe diameter:
Example:
Pipe DN300
=> 300 mm × 10 = 3000 mm
=> minimum distance = 3 m
The time between chlorine addition and
excess chlorine measurement is the soak time.
It consists of the travel time between chlorine
addition point and sample water take-off and
the travel time between sample water take-off
and measurement (sample water line to flow
cell). Keep the sample water line to the flow
cell as short as possible.
For longer required soak times, for example 5
to 15 minutes, a delay tank can be installed
into the sample water line immediately before
the flow cell. Note that the longer soak time
prevents chlorine addition control based
purely on excess chlorine. Instead, combined
flow and excess chlorine dependent control
must be used. This also applies to the use of
chlorine, chlorine dioxide and ozone as disin-
fectant.
4.3.3 Installation site for pool water
The sample water take-off point must be
installed in the pool return line according to
standards (see DIN 19643, DIN = German
Industrial Norm). Make sure that the sample
water take-off point is upstream of the floccu-
lant station.

Mechanical installation
NOTICE
Correct and safe operation can only be gua-
ranteed if the requirements for the ambient
conditions are met. All applicable national
and local regulations must be observed!
WARNING
Risk of injury or damage to the installation!
•
Only authorized and qualified electrici-
ans are permitted to install the flow cell.
•
All electrical work on the equipment
must be performed only by authorized
and qualified electricians.
•
Modifications to the device other than
those described in this instruction
manual are not permitted.
NOTICE
•
Install the flow cell to the left of the
electronics module.
•
Leave a clearance of at least 250 mm
above the flow cell for working with the
sensors.
•
Screws and dowels for fixing to a solid
wall are included in the scope of delivery.
•
Tallow-drop screws and dowels for fixing
to a solid wall are included in the scope
of delivery.
•
If the device is to be installed on a suita-
ble lightweight wall, use the appropriate
mounting fixtures. Not included in the
scope of delivery!
•
The electronics module is not suitable
for electrical connection with perman-
ently installed cable conduits. If the
cable glands do not meet local installa-
tion rules and regulations, these glands
must be replaced with suitable ones.
•
If electronics module and flow cell are
installed in different locations, you must
use CAN bus extension cable (optional).
This must not be longer than 1000 m.
•
Measurement are shown in millimeters.
To convert to inch measurement, divide
by 25.4 (1 inch = 25.4 mm).
