2.4 Residual risks
Electric shock
Components in the device are energised with
life-threatening voltage. Before working on the unit:
Disconnect the device from power supply.
Protect the device against being switched back
on again.
Existing earthing connections within housings or on
mounting plates must not be altered. If this should nev-
ertheless be necessary in the course of repair or as-
sembly work:
Restore earthing connections to their original con-
dition after completion of the work.
Injuries caused by high temperatures
Before working on the unit, let it cool down.
Safety labels
Observe safety labels on and in the unit.
2.5 Avoid damage to property
Improper action
Requirements for minimum scale and corrosion dam-
age in hot water heating systems:
Proper planning, design and commissioning
Closed system with regard to corrosion
Integration of an adequately dimensioned pres-
sure maintaining device
water corresponding to the VDI 2035 norm
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated according to the given requirements, there is
a risk that the following damage and faults will occur:
Malfunctions and the failure of components, e.g.
pumps, valves
Internal and external leaks, e.g. from heat ex-
changers
Cross-section reduction and blockages in compo-
nents, e.g. heat exchanger, pipes, pumps
Material fatigue
-
coatings, deposits, and associated noises, e.g.

3.1 Energy and environmentally
conscious operation
The generally accepted requirements for energy con-
scious and environmentally conscious operation of a
heating system also apply to use of a heat pump. The
most important measures include:
No unnecessarily high domestic hot water tem-
Do not open windows with just a gap or tilt open
Always ensure that the controller settings are cor-
