8. Installation
8.1 Transport and storage
8.2 Unpacking
• Check the scope of delivery.
• Install as soon as possible after unpacking.
8.3 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
Conex
®
DIA and the motor of the measuring cell.
• Maximum permissible cable length between measuring cell
and measuring amplifier: 3 metres.
• Ensure a continuous supply of sample water.
• Retain the permissible inlet pressure and counter-pressure of
the sample water.
– Fit a pressure booster pump or pressure reducer, if
necessary.
8.4 Mounting
The flow armature is fastened to the mounting plate from factory.
1. Drill four dowel holes with a diameter of 10 mm and minimum
60 mm deep. See section
6.2 Dimensional sketch / drilling
2. Mount the mounting plate on the wall using the mounting
material provided. Distance between the mounting plate and
the wall: minimum 20 mm.
