meanings in this Operating Manual:
CAUTION Is used if non-precise observance or non-observance of operating instructions, work in-
structions, specified sequences and such like may lead to injuries or accidents.
WARNING Is used if non-precise observance or non-observance of operating instructions, work in-
structions, specified sequences and such like may lead to damage to the equipment.
*IMPORTANT Is used if particular attention in handling the equipment is required.
)NOTE Is used if attention is to be drawn to a special feature.
2.3 Special safety information for maintenance and repair work
CAUTION
Suitable protective clothing must be worn when carrying out service and repair work and
during handling the system. All relevant safety regulations, which apply when handling
chemicals, must always be observed.
The unit must be installed as far away as possible from any risks and physical hazards.
Before any repair work is carried out, the dishwasher must be disconnected from the
power supply.
Any material of this unit, which is subject to disposal (packing material, replacement
parts etc.) must always be disposed of i.a.w. all applicable local and international envi-
ronmental protection laws and -regulations.

4 Functional description, operation and settings
The control electronic is supplied with voltage via an external transformer (see accessory
list) as soon as the corresponding enabling signal from the dishwasher is applied. The
green LED at the front side of the unit lights up continuously in operation mode or is flash-
ing in standby mode.
The metering can be performed in “continuous controlled”, “timed controlled” or in “conduc-
tivity controlled” dosing mode. These modes can be set on the PCB
4.1 Settings
Detailed description see: “Operation manual Ecodos-PCB 2.237.82”
4.2 Adjustment of buzzer volume
The unit comprises a buzzer for the acoustical alarm indication. It’s volume can be changed
by manually turning the inner disk (see illustration below).

5 Mounting and installation
5.1 Pre-installation requirements
)NOTE 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. 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:
- Mounting height: max. 1.8 meters
- Distance between unit and product container: max. 3.0 meters
5.2 Overview
Not available for field test units.
5.3 Wall mounting
Perform the mounting as follows:
1. Mark two drilling holes by using the holes of the unit housing as a template and drill holes.
2. Mount the housing using appropriate wall anchors
(screws and dowels, p/o delivery content).
5.4 Installation of the product feed line and the metering hose
Perform the installation of the product feed- and metering line as follows:
1. Mark water level within the wash tank and drain tank.
2. Drill appropriate hole into wash tank wall.
3. Install an appropriate tank connector to the tank wall.
4. Install metering hose between unit and tank connector.
5. Install the product feed line between the unit and the pick up probe (if available).
5.5 Installation of conductivity sensor
)NOTE
When selecting the measuring and metering points in the tank, the flow conditions in the
wash liquor must be considered. The measuring point must always be behind the mete-
ring 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 Distance
tank corners at least 50 mm
heating elements as far as possible
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 “7 8” of PCB
