The dosing device is supplied ready to use on a roller carrier.
The device is assembled in the technical room approximately 1 m above the floor. In case of Installation with
console, the device can be assembled at any height. The container with the fragrances concentrate is put

Hydraulic installation
ATTENTION !
Do not bend the dosing pipe.
Install the dosing pipe in such a way that the fragrance concentrate cannot flow through
the steam pipe into the steam generator.
1.
If necessary, screw the dosing valve (option) at the dosing point in the steam pipe.
2. In case of a bigger distance between the installation place and the dosing valve, install a transparent protec-
tion pipe for the dosing pipe, if necessary.
3. Connect the dosing pipe at the right connection of the hose pump.
4. Connect the other end of the dosing pipe onto the steam pipe (dosing valve).
5. Connect the suction pipe at the left connection of the hose pump.
Electrical installation
The dosing pump is supplied with connection cable without plug. The pump starts running as soon as power
is supplied. Therefore the pump must be connected to an external control.
See Section 9.2, “Terminal plan“.
Do not open the casing.
DANGER DUE TO HIGH VOLTAGE !
The electrical installation may only be performed by appropriately trained specialist
staff! The device must be switched off and secured against re-operation before any
electrical work is carried out!
Hint !
The dosing of the fragrance concentrate must be coupled with the function of the steam
generator. This avoids a dosing without steam. For example, lock the power output
with steam generator or by means of a temperature probe on the steam pipe.
