DANGER
Risk of fatal injury from falling parts!
The pump itself and pump parts can have a very high net weight. Falling parts pose a risk of
cuts, crush injuries, bruises or impacts which can be fatal.
• Always wear suitable protective equipment (e.g. helmet, gloves).
• Always use suitable lifting equipment and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and assembly work, ensure
that the pump is in a safe and secure position.
6.4

Preparing the installation

1. Attach pipes to the floor, ceiling or wall using appropriate fittings so that the pump does not bear the
weight of the piping.
2. Branch off the safety feed ahead of the pump when installing in feed of open systems (EN 12828).
3. Install the pump at an easily accessible point so that it can be easily checked or replaced at a later time.
4. Complete all welding and soldering processes.
5. Flush system.
6. Provide shut-off valves upstream and downstream of the pump.
7. Comply with the inlet and outlet sections in front of and behind the pump.
8. Make sure that the pump can be installed free of mechanical stresses.
9. Allow a 10 cm distance around the control module so that it does not overheat.
10. Observe permissible installation positions.
Installation within a building
The pump should be installed in a dry, well ventilated and dust-free room – in accordance with the protection
class (see rating plate of the pump).
CAUTION
Exceeding/dropping below the permissible ambient temperature!
The control module switches off in the event of excessive temperatures!
• Provide adequate ventilation/heating!
• Never cover the control module and pump with objects!
• Observe permissible ambient temperatures (see "Technical data" table).
Installation outside a building (outdoor installation)
• Observe permissible environmental conditions and protection class.
• Install the pump in a housing as weather protection. Observe permissible ambient temperatures (see "Tech-
nical data" table).
• Protect the pump against the effects of weather, for example, direct sunlight, rain and snow.
• Protect the pump so that the condensate drain openings remain free of dirt.
• Take suitable measures to prevent the formation of condensation water.
