4.1 Installation into pipeline

4.1.1 Safety instructions

Danger
If used not according to intention, the tap can be a danger to persons,
systems in the surroundings and to the environment.
Only use the tap as intended in regulations.
Injury through high pressure in the system.
Clear the pipelines of pressure and media before assembling
the tap.
Danger through uncontrolled start-up of the system
Secure the system against unintentional operation during
installation.
After an interruption of the electrical or fluid supply, a defined or
controlled re-run of the process must be ensured.
Warning
The tap is not designed for outside usage.
Temperature, light and moisture influences can lead to
malfunctions and damage to devices.
Do not use the tap outside.
Danger through improper installation
Performance of tasks only by qualified personnel (see section
1.6).
Danger of burning from high media temperatures.
Clear the pipelines of pressure and media before assembling
the tap.
Let the system cool down before installing the tap.
Caution
Damaged or wrongly installed tap.
Malfunctions
Do not damage the tap and only install in clean, perfectly
functioning condition.
Install the tap according to the described arrangement.
Install free of voltage and of bending moments.
Individual housing parts are to be removed for the installation
process, which means that the IP protection of the device is no longer
complete.
No water is to enter into the device interior during assembly.

4.1.2 Installation notes

• Install input and output shut-off valves
• When filling and connecting up the media system with a drinking water
supply, a suitable system separator is to be set upstream (optionally
available)
• Suitable filter against particles ≥ 600μm set upstream
- Refill unit is protected against malfunctions and corrosion damage from rinsed-in
foreign bodies, for instance sweat drops, sealing material, swarf or rust
• Installation into horizontal pipeline
• The installation may not take place in areas or ducts where poisonous
gases or vapours may be present or where flooding can occur
• The installation location must be ventilated well
• The installation location should be protected against frost and be easily
accessible
- Simplified maintenance and cleaning
- The display on the device can be viewed very well
• Calm-down distance provided of at least 5xDN after refill unit (correspon-
ding DIN 1988, part 5)

4.2 Electrical connection

4.2.1 Safety instructions
Danger
Danger of injury from electric voltage.
High shock currents and burns from direct and indirect contact
with live parts.
Switch off power supply before assembly of the tap and secure
against being switched on again.
Non- or erroneously-connected cables
Malfunctions, which endanger the safety of operating personnel.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Wrongly wired connections
Destruction of electrical / electronic components.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Improperly connected wiring and lines (e.g. too small bend radius)
Smouldering and fires from cables.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Live cable ends and components
Make sure the protective earth system is connected throughout.
