• Fit the multi-function valve directly on the pressure valve of the
dosing pump.
Refer to the installation and operating instructions for the multi-
function valve.
5.2.5 Installation of the dosing lines
Route hoses free from mechanical tension and
bends.
Only use the clamp rings and hose connectors
intended for the hose diameter in question.
Caution
Only use original hoses with the required dimensions
and wall thickness.
Observe the maximum permissible operating
pressure.
Connect the suction line to the suction valve of the dosing pump.
Connect the discharge line to the discharge valve or to the multi-
function valve of the dosing pump.
1. Cut the hose ends to length (straight cut).
2. Pull the union nut and the clamp ring over the hose.
3. Slide the hose end over the connector until the stop, widen if
necessary. Depending on the type of connection, secure it
with a counterpiece or a hose clip.
4. Fit gasket.
– Ensure that the O-ring or flat gasket is positioned correctly
in the counterpiece (pump valve/injection unit).
5. Use the union nut to screw the hose on the valve.
Refer to the installation and operating instructions for the dosing
pump.
5.2.6 Installation of the injection unit
• Screw the injection unit into the coupling thread (provided by
