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.
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
Use of demineralised heating water (VE water) or
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
Gas bubbles and gas cushion formation (cavita-
tion)

3 Operation and care
NOTE
The device is operated via the control panel
of the heating and heat pump controller
( operating manual of the heating and
heat pump controller).
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-
perature (note and follow local regulations)
Do not open windows with just a gap or tilt open
(continuous ventilation), but instead open wide for
a short time (shock ventilation)
Always ensure that the controller settings are cor-
rect

damage to property if the device falls or overturns.
The hydraulic connections are not designed for me-
chanical loads.
Do not lift or transport the device by the hydraulic
connections.
Transport the device preferably with a pallet truck,
alternatively with a handcart or by carrying.

2. Dispose of the transport and packaging material
in an environmentally friendly way and in accord-
ance with local regulations.
If the device is to be carried, then it is recommended
that the wooden pallet is not removed yet.
5.2.2 Making transport easier
In order to make the transport simpler and easier, the
whole hydraulic system(including the controller with
switch box) can be unscrewed beforehand.

IMPORTANT
Dirt and deposits in the (existing) hydraulic system
can cause damage to the heat pump.
Ensure that a sludge separator is installed in the
hydraulic system.
Rinse the hydraulic system thoroughly prior to es-
tablishing the hydraulic connection of the heat
pump.
IMPORTANT
Damage to the copper pipes due to unacceptable
loading!
Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned. In do-
ing so, ensure that the connection pipework be-
tween the heat pump and hydraulic station are also
taken into account.
Freely pressing the recirculating pump produces
at least the minimum throughput required for the
device type ( “Free pressing”, page 21).

Contact the local partner of the manufacturer or
the factory's customer service. Have the fault
message and device number to hand.
14.1 Unlock the safety temperature
limiter
A safety temperature limiter is installed in the electric
heating element. If the heat pump fails or there is air in
the system:
Check whether the reset button (①) in the centre
of the safety temperature limiter (②, located
underneath the cover) has tripped.
If the reset button (①) has tripped, press it again
using a small screwdriver (③) .
