Mechanical installation
Installing dosing device
With the exception of the roller support, the dosing device is delivered ready for operation.
The device is installed in the utility room approx. 1 m above the ground. When installed with a console, the
device can be installed at any height desired. The container with the fragrance concentrate is placed under
the device.
1. When selecting the installation site, make sure it is easily accessible.
2. Attach the device to the wall or console using 4 screws.
Hydraulic installation
ATTENTION!
Do not bend the dosing line.
Do not install the dosing line in such a way that the fragrance concentrate is unable to
flow through the steam pipe into the steam generator.
1.
Screw in the dosing valve (optional) at the dosing point on the steam pipe.
2. If there is a large distance between the device installation site and the dosing valve, fit a transparent protective
tube for the dosing line.
3. Connect the dosing line to the right-hand connection of the hose pump.
4. Connect the other end of the dosing line to the steam pipe (dosing valve).
5. Connect the suction line to the left-hand connection of the hose pump.
Electric installation
DANGER DUE TO ELECTRICAL VOLTAGE!
Electrical installation must only be carried out by appropriately qualified personnel!
Before any electrical works are carried out, the device must be disconnected from the
power supply and secured against being reactivated! (Pull power plug.)
ATTENTION!
The electronic components in the devices are sensitive to electrostatic discharges. The
generally accepted safety precautions for ESD-sensitive devices must be observed when
handling the devices.
The following applies, in particular:

Connectors must only be connected or removed when the power has been deactivated.

The person handling the devices must discharge any electrostatic charge from themselves for
at least 5 seconds before touching the device directly. For example, by wearing an ESD
antistatic wrist strap connected to an earth wire.
Tip!
The dosing of the fragrance concentrate must be linked with the functioning of the
steam generator. This prevents dosing without steam. For example, interlock socket
with steam generator or via a temperature sensor located on the steam pipe.
