Mounting and installation

5.1

Pre-installation requirements

Mounting and installation guidelines will be suggested as the preferred method. However
varying types of conditions and surrounding physical environments will dictate the actual
mounting and installation.
NOTE
The installation must be in accordance with all local regulations.
In order to ensure correct operation of the unit, the following dimensions must not be
exceeded. Distance between unit and product container: max. 3.0 meters
5.2

Installation of conductivity sensor

When selecting the measuring and metering points in the tank, the flow conditions in the
wash liquor must be considered.
NOTE
The measuring point must always be behind the metering point with regard to the flow
direction.
In order to ensure correct operation of the unit, the following installation instructions for
the measuring cell must be followed:
Distance from
tank corners
heating elements
Perform the installation and connection of the conductivity sensor as follows:
1. Drill an appropriate hole into the tank wall.
2. Install sensor into tank.
3. W. Inductive probe:
- Connect sensor w. plug to unit
W. 2-wire probe
- Install the connection cable to the sensor.
- Connect the cable to screw terminal "8 + 9" of PCB
5.3

Electrical connection

The permitted operating voltage for the unit is AC 24V, ± 10%, 50-60 Hz.
The use of the internal transformer of the dishwasher in case of 2-wire-conductivity
CAUTION
controlled system may cause malfunction or danger!
Special caution is required regarding energized or current-leading items.
During electrical connection of the unit, all valid international, national and local safety
regulations must be complied with.
WARNING
The electrical connection to the dishwasher must be performed by using the original
transformer (see accessory list).
Never connect both probe types (inductive, 2-wire) simultaneous at one PCB.
