1.1 Important information

ATTENTION!
The device is not suitable for operation with a frequency converter.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride, as
these can damage the surfaces.
ATTENTION!
Before opening the device, ensure that all circuits are powered down.
ATTENTION!
The hydro tower is to be fixed to the transport pallet with screws.
ATTENTION!
Work on the system must only be performed by authorised and qualified
after-sales service technicians.
The operational reliability of the safety valve should be checked
at regular intervals. We recommend having an annual service in-
spection carried out by a qualified specialist company.
The outflow from the safety valve should visibly flow into a waste
water drain.
The installer of the heating system is responsible for checking
whether an additional expansion vessel is required.
Operating the system in a sensible way can provide significant
energy savings. The heating water temperature should be as low
as required during heat pump operation. The planner of the heat-
ing system is responsible for determining the system tempera-
ture.
When installing an underfloor heating system, a sensible value
for the maximum flow and return temperature should be set on
the heat pump controller. The position of the temperature sensor
is important in this regard.
1.2 Legal regulations and
guidelines
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EC directive 2006/42/EC
(machinery directive) and is thus subject to the requirements of
EC directive 2006/95/EC (low-voltage directive). It is thus also in-
tended for use by non-professionals for heating shops, offices
and other similar working environments, in agricultural establish-
ments and in hotels, guest houses and similar / other residential
buildings.
The construction and design of the hydro tower complies with all
relevant EU directives, DIN and VDE regulations (see CE de-
claration of conformity).
When connecting the hydro tower to the power supply, the rele-
vant VDE, EN and IEC standards must be fulfilled. Any further
connection requirements stipulated by the mains supply network
operator must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
EN-2
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or due to their inexperience or lack of knowledge, must not oper-
ate this device without supervision or instruction by the person in
charge.
Children must be supervised to ensure that they do not play with
the device.
2 Purpose of the hydro
tower

2.1 Application

The hydro tower constitutes the interface between a non-revers-
ible heat pump and the heating system in the building. The hydro
tower contains all hydraulic components required between heat
generation and heat distribution with an unmixed heating circuit.
A dual differential pressureless manifold with a buffer tank allows
an energetically optimised hydraulic integration of the heat gen-
erator and the heat consumers.
ATTENTION!
The device is not suitable for operation with a frequency converter.

2.2 General properties

Low installation effort
All components easily accessible
Ready-to-connect, contains all essential components, i.e.
pumps, shut-offs, safety devices and heat pump manager
(HWK 332 Econ)
Integrated 300l hot water cylinder
Integrated buffer tank reduces operating cycles of the heat
pump, thus increasing the efficiency of the system
The infinitely adjustable operation of the circulating pump in
the heating circuit allows the output to be adjusted according
to need.
Optional immersion heater up to 6 kW
Switchable pipe heater (2 / 4 / 6 kW) for supplementary heat-
ing.
