Warnin g
When working with chemicals, the accident
prevention regulations applicable at the
installation site must be applied.
Observe the chemical manufacturer's safety data
sheets when handling chemicals.
Warnin g
When working on the product, or connections
and lines, always wear protective clothing (e.g.
safety goggles and gloves).
The system must be unpressurised.
Only operate the system if all lines are connected
correctly.
Warnin g
The chemical resistance of the parts that come
into contact with the dosing medium depends on
the medium, media temperature and operating
pressure.
Ensure that all parts in contact with the medium
are resistant to th e med ium un der opera tin g
conditions.
English (GB)
Warning
Prior to installation, read these installation and
operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.

Warning
Danger of chemical burn!
Avoid direct contact with chemicals.
Wear protective clothing when handling
chemicals.
4.1.1 Conditions for installation
• Proper functioning can only be guaranteed when using
Grundfos accessories.
• For suction height and line diameter, please see the technical
data of the pump.
4.1.2 Notes for installa tion
• Shorten the hoses at right angles.
• Make sure there are no loops or kinks in the hoses.
• Keep the suction line as short as possible.
• Install the suction line upwards to the suction valve of the
pump.
4.1.3 Connecting the hose (fig. 4)
1. Slide union nut (2) and tensioning ring (3) onto the hose (1).
2. Insert the cone part (4) fully into the hose.
3. Put the cone part with hose onto the corresponding threaded
connection of foot valve / suction lance or suction valve of the
pump.
4. Tighten union nut manually. Do not use any tools!
– Tighten up union nut after 2-5 operating hours if using
PTFE gaskets!
5. If existing, insert the deaeration line of the pump and the relief
line of the multi-function or pressure relief valve via the
corresponding connection of the foot valve or suction lance
into the container.

Note

2
In order to monitor the filling level of the container, a two-step
level indication (low-level signal, tank-empty signal) can be connected to the pump or other downstream devices.
Observe the manuals of the downstream devices.
4.2.1 Signal connection with round plug
All SMART Digital pumps and the digital dosing pump DDI 222
are connected with round plugs.
4.2.3 Changing the contact type
Suction lances and foot valves with two-step level indication have
two signal outputs. Both are factory-set to NO contact type.
The symbol is on the floater top (see fig. 7).
• The symbol that is visible from above shows the switch mode
"floater above".
• The symbol that is visible from below shows the switch mode
"floater below".
The contact type can be changed from NO to NC by turning the
floater horizontally by 180 °. A cable break will provoke a
tank-empty signal.
Reversing the floater:
1. Remove the floater sidewards
2. Turn the floater horizontally by 180 ° and attach it. Make sure
that the NC symbol at the floater points upwards.
3. Adjust the signal inputs of the downstream devices (pump)
accordingly
Observe the manuals of the downstream devices
(pump).
