8. Installation
8.1 Transport and storage
• Transport the device carefully, do not drop!
• Store the electrodes with electrolyte filling and protection cap
fitted.
• Store at a dry location, protected from direct sunlight.
– Storage temperature for measuring modules: -5 °C to +50
°C.
8.2 Unpacking
• When unpacking, be aware of loose parts.
• Check the delivery to ensure that no parts are missing.
• Also check for transport damage. Never fit or connect any
damaged parts.
• Install as soon as possible after unpacking.
8.3 Installation requirements
• Ambient temperature of +5 to 35 °C at the installation site.
• Vibration-free location.
8.4 Installation
• The fixing accessories supplied include hanger bolts, dowel
pins, compression springs and nuts.
• Attach the AQC-D6 measuring cell or the measuring module to
a stone or concrete wall using the fixing accessories supplied.
Do not twist or distort the devices.
• Nuts may be attached behind the base plate to ensure that the
module is free from distortion when attached to an uneven
wall.
1. Mark the location of the boreholes, and then drill them (
∅
10
mm). See section
6.3 Dimensional sketch / drilling diagram
2. Insert the dowel pins, and screw the AQC-D6 measuring cell
or the measuring module onto the wall.
9. Commissioning
9.1 Water connections
9.1.1 AQC-D6 water connections
Fig. 8
AQC-D6 with open water outlet
• Connect the sample water supply line (hose 6/8 mm).
• Connect the sample water drain line.
• Do one of the following:
– When a drain is available, connect (hose 6/8 mm) to a
suitable drain.
– Feed the fluid back to the pipework.
9.1.2 Measuring module water connections
The standard scope of delivery includes one PP and one PVC
insertion section each for the input and output of the measuring
module for connecting a pipe in DN 20.
When installing, do one of the following:
• Weld on a PP pipe.
• Glue on a PVC pipe (only suitable for cold water).
9.1.3 Water sensor of the AQC-D6
1. Screw the water sensor into the thread all the way to the stop.
2. Secure with the PVDF ring.
Note
Do not allow foreign bodies to enter any parts that
carry water.
Note
Retain the packing material or dispose of it according
to local regulations.
Note
The measuring module should be fitted as close as
possible to the main water line.
Note
The installation of the sample-water feed pipe must
not contain any copper. Copper interferes with the
measurement and can damage the electrodes.
Caution
Always fit the AQC-D6 measuring cell or measuring
module on a flat and stable surface. Do not twist or
distort the base plate.
Caution
Observe the maximum permissible pressures and
temperatures for materials used! The measuring cell
must
never be exposed to shock pressure. It can be
operated up to a maximum of 8 bar.
Caution
When selecting the supply and discharge conduits,
please observe their resistance against the
temperature and pressure occurring in your
application.
Note
For the best possible accuracy of the measured
value, keep the flow of sample water as constant as
possible.
Note
To keep the system short and prevent drops in
pressure, the connection lines to the measuring cell
or the measuring module should be kept as short as
possible.
