11. Installation
11.1 Transport and storage
11.2 Unpacking
• Check scope of delivery.
• Assemble as soon as possible following unpacking.
11.3 Installation requirements
• The location must be vibration-free, dry, dust-free and free of
corrosive, pungent fumes or aggressive solvents.
• For safety reasons, the customer should install an earth
leakage circuit breaker for the measuring amplifier.
• Maximum permissible cable length:
– Individual devices for AQC-D3 measuring cells: between
measuring cell and measuring amplifier or sensor interface:
3 m.
– Preassembled systems with Conex DIS, DIA or DIP as
wall-mounted unit: completely prewired.
– Preassembled systems with Conex DIA as control cabinet
unit: Distance between measuring amplifier and sensor
interface

100 m.
• Ensure a continuous supply of sample water.
• Install the measuring cell so that the line length of the sample
water feed is as short as possible in order to reduce the delay
time of the flow armature.
• Retain the permissible inlet pressure and counter-pressure of
the sample water.
– Fit a pressure booster pump or pressure reducer, if
necessary.
11.4 Mounting
The flow armature is fastened to the mounting plate from factory.
Individual device for AQC-D3 measuring cells
1. Drill four dowel holes with a diameter of 10 mm and min.
60 mm deep. See section
10.4 Dimensional sketches / drilling
diagram
.
2. Mount the measuring cell and the mounting plate on the wall
using the mounting material provided.

Caution
Transport unit carefully, do not throw, store in
dry conditions between –20 and +65 °C.
Store electrodes between –10 and +30 °C.
Keep protective caps moist with 3-molar
potassium chloride solution.
Caution
Do not allow any foreign bodies to enter!
Caution
Non-observance may result in damage or errors
in measurement!
Caution
The measuring cell breaks when the screws are
tightened! Do not tighten the screws; only screw
them in without tightening them!
Caution
The potentiostatic measuring cell or
preassembled system must be mounted
vertically!
