5. Installation
5.1 General information on installation
5.2 Installation location
5.2.1 Space required for operation and
maintenance
The control elements must be easily accessible
during operation.
Maintenance work on the dosing head and the
valves must be carried out regularly.
Provide sufficient space for removing the dosing
head and the valves.
5.2.2 Permissible ambient influences
Permissible ambient temperature: 0 °C to +40 °C.
Permissible air humidity: max. relative humidity:
92 % (non-condensing).
5.2.3 Mounting surface
The pump must be mounted on a flat surface.
5.3 Mounting
5.3.1 Horizontal mounting
Fig. 10
Drilling scheme
•
Use four M6 screws to mount the pump on the
tank or on a console so that the suction valve is
at the bottom and the discharge valve is at the
top (dosing always flows upwards).
5.3.2 Vertical mounting
1. Mount the pump on a vertical surface (e.g. a wall)
using four M6 screws.
2. Unscrew the dosing head (four inner dosing head
screws (1q + 2q)).
3. Turn the intermediate ring (4q) so that the
discharge hole points downwards.
4. Turn the dosing head 90 ° so that the suction
valve is at the bottom and the discharge valve is
at the top (dosing always flows upwards).
5. Cross-tighten the screws using a torque wrench.
Maximum torque:
DDI 0.4 - DDI 5.5: 2.1 Nm.
DDI 13.8 - DDI 20: 2.5 Nm.

5.3.3 Diaphragm leakage detection
With diaphragm leakage detection:
•
Screw the sensor from the bottom into the
opening in the dosing head flange.
Warning
Observe the specifications for the
installation location and range of
applications described in sections
1. General information and
5.2 Installation location.
Warning
Faults, incorrect operation or faults on
the pump or system can, for example,
lead to excessive or insufficient
dosing, or the permissible pressure
may be exceeded. Consequential faults
or damage must be evaluated by the
operator and appropriate precautions
must be taken to avoid them!
Caution
The DDI 0.4-10 (not with Plus
3
system)
should be operated with flooded
suction!
Note
The pump must be installed in a
position where it is easily accessible
during operation and maintenance
work.
Caution
The installation site must be under
cover!
Ensure that the enclosure class of
motor and pump is not affected by the
atmospheric conditions.
Pumps with electronics are only
suitable for indoor use!
Do not install outdoors!
Caution
Carefully tighten the screws, otherwise
the plastic housing may be damaged.
