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:
