4 Assembly and installation
4.1 Pump assembly
The pump is delivered with a mounting plate. The mounting plate can be mounted vertically,e.g. on a wall, or horizontally, e.g. as on a tank. It takes only a few quick steps to firmlysecure the pump to the mounting plate by means of a slot mechanism.The pump can easily be released from the mounting plate for maintenance.
4.1.1 Requirements
- The mounting surface must be stable and must not vibrate.- The direction of dosing should be vertically from bottom to top.
4.1.2 Align the mounting plate and install it.
- Vertical installation: The mounting plate slot mechanism must be on top.- Horizontal installation: The mounting plate slot mechanism must be opposite the
dosing head.- The mounting plate can be used as a drilling template; for drill hole distances, see
above figure.
Attaching the mounting plate
CautionTake care that no cables or lines are damaged during installation!
1. Mark the drilling holes.2. Drill the holes.3. Secure the mounting plate with four screws (5 mm diameter), to the wall, on the
mounting bracket, or on the tank.
4.1.3 Engage pump in mounting plate
Attach the pump to the mounting plate support clamps and slide under slight pressureuntil it engages.

4.2 Hydraulic connection
Caution:Danger of chemical burns!Wear protective clothing (gloves and safety glasses) while working on dosing head,on connectors or cables!
Warning:The dosing head may contain water from the factory inspection. When dosing mediawhich should not come into contact with water, another medium must be dosedbeforehand!
Warning:A proper function can only be guaranteed when lines supplied by dinotec are used.The used lines must correspond to the pressure limits specified in chapter 3"Technical data".
Important details regarding the installation- Observe suction lift and cable diameter, see chapter 3 "Technical data".- Shorten the hoses at right angles.- Ensure that there are no loops or kinks in the hoses.- Keep the suction lines as short as possible.- Route suction line up towards the suction valve.- Installing a filter in the suction line protects the entire installation from dirt, thus
reducing the risk of leakage.
How to connect the hose1. Slide the union nut and tensioning ring on the hose.2. Insert the cone part completely into the tube (slide in).3. Push union nut and tensioning ring across hose.4. Tighten the union nut by hand.
– Do not use any tools!– When PTFE is used as sealing material, re-tighten the union nut after 2-5
hours of operation!5. Attach the deaeration hose to the corresponding connection and lead it into a
receptacle, such as a drip pan.
Note:The pressure differential between the suction and pressure side must be at least 1bar!
Warning:Re-tighten the dosing head screws with 3 Nm before commissioning and after 2 - 5hours of operation.

6 Operation
6.1 Operating elements
Adjustment knobUse the capacity adjustment knob to set the dosing capacity in percent of the maximumdosing flow of the pump. Due to the logarithmical increase of the percent values, even smalldosing capacities can be set accurately.
Mechanical lockThe mechanical lock protects the set dosing capacity against unauthorised manipulation. Forlocking, tighten the screw until the adjustment knob cannot be turned anymore.
Keys and LEDsWhen pressing and holding down the deaeration key, the pump doses at 100 % for a certaintime. The deaeration key can be used e.g. for deaeration.The operation mode switch is used to change between the ’Manual’ and ’Pulse’ modes (seechapter.6.2 "Operating modes"). Depending on the current mode, the respective status LEDis active ("Pulse" = upper LED; "Manual" = lower LED).The status LEDs indicate the following operating states and faults:

6.2 Operating modes
The following operating modes are available:
Manual, see chapter 6.2.1
Pulse, see chapter 6.2.2)
6.2.1 Manual
In this operation mode, the pump doses constantly the dosing quantity set by the adjustmentknob.
The setting range is dependent on the pump type:
Type Setting range [l/h]
DDE 6-10 0.0060 – 6
DDE 15-4 0.0150 - 15
6.2.2 Pulse
In this operating mode, the pump adds the set dosing quantity for each incoming (potential-free) pulse, e.g. from a water meter. There is no direct connection between incoming pulsesand dosing strokes. The pump automatically calculates the optimum stroke frequency fordosing the set volume per pulse.
The calculation is based on:- the frequency of external pulses- the set stroke volume in percent
The dosing quantity per pulse is set to a value between 0.1% and 100% of the stroke volumeusing the adjustment knob.
The setting range is dependent on the pump type:
Type Setting range [ml/pulse]
DDE 6-10 0.0008 - 0.81
DDE 15-4 0.0016 - 1.58
The frequency of the incoming pulses is multiplied by the set dosing quantity. If the pumpreceives more pulses than it can process at the maximum dosing flow, it runs at themaximum stroke frequency in continuous operation. Excess pulses will be ignored.
Note:To achieve the maximum dosing capacity, we recommend the following setting fordinotec measurement and control devices (also dinotecNET ready and AquaTouch), ifthey are set to pulse frequency:
Type Frequency (pulses/h) atcontrol unit
DDE 6-10 7200
DDE 15-4 9600
Please observe our operating instructions for your measuring and control device.
