5.1 General notes
5.2 Check before commissioning
•
Check that the rated voltage indicated on the
nameplate complies with the local conditions.
•
Check that all connections are assembled
correctly. Tighten connections, if necessary.
•
Check that the dosing head screws are tightened
with the indicated torque (3 Nm). Tighten dosing
head screws, if necessary.
•
Check that all electrical cables and plugs are
connected correctly.
5.3 Start and deaerate the pump
1. Connect mains supply
(see
4.3 Electrical connection
).
2. Open the deaeration valve by approximately half
a turn.
3. DDE-PR/P control variant: Press the [100 %] key
and hold it down, until liquid flows out of the
deaeration hose continuously and without any
bubbles.
4. DDE-B control variant: Turn the capacity
adjustment knob to 100 % and wait, until liquid
flows out of the deaeration hose continuously
and without any bubbles. Then set the capacity
adjustment knob back to 0 %.
5. Close the deaeration valve.
The pump is deaerated.
6. Operation

Operating elements
* Applies to DDE-PR/P control variant.
Capacity adjustment knob
The capacity adjustment knob is used to set the
capacity in percent of the maximum dosing flow of
the pump. Due to the logarithmical increase of the
percent values, even small dosing capacities can be
set accurately.
Mechanical lock
The mechanical lock protects the set dosing capacity
against unauthorised manipulation. For locking,
tighten the screw until the adjustment knob cannot
be turned anymore.
Keys and LEDs
When pressing and holding down the [100 %] key,
the pump doses at 100 % for a certain time.
The [100 %] key can be used e.g. for deaeration.
The [Operation mode] key is used to change
between the "Manual" and "Pulse" mode
(see section
6.2.3
). According to the selected
operation mode, the respective status LED is active
("Pulse" = LED above key; "Manual" = LED below
key).
Warning
Suction and discharge hoses must be
connected correctly!
The deaeration hose must be
connected correctly and inserted into a
suitable tank!
Caution
Tighten up the dosing head screws
once before commissioning and after
2-5 operating hours at 3 Nm.
