1.1 Important Information:

ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
ATTENTION!
The transport securing device is to be removed prior to commissioning.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
ATTENTION!
Ensure that there is a clockwise rotating field: With incorrect wiring the
starting of the heat pump is prevented. A corresponding warning is
indicated on the display of the heat pump manager (adjust wiring).
ATTENTION!
It is not permitted to connect more than one electronically regulated
circulating pump via a relay output.
ATTENTION!
Operating the heat pump at low system temperatures may cause the heat
pump to break down completely.
ATTENTION!
The integrated dirt trap must be cleaned at regular intervals.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.

1.2 Intended Use

This device is only intended for use as specified by the manufac-
turer. Any other use beyond that intended by the manufacturer is
prohibited. This requires the user to abide by the relevant project
planning documents. Please refrain from tampering with or alter-
ing the device.

1.3 Legal Regulations and
Directives
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 heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be fulfilled. Any further
connection requirements stipulated by local utility companies
must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or their inexperience or lack of knowledge, must not operate 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.
ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
1.4 Energy-Efficient Use of the
Heat Pump
With the purchase of this heat pump you are helping to protect
the environment. A prerequisite for energy-efficient operation is
the correct design of the heat source system and heating system
(radiators and circulation pump).
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and heat
source as small as possible. For this reason, it is advisable to de-
sign the heat source and heating system very carefully. A tem-
perature difference of approx. one Kelvin increases the
power consumption by around 2.5 %. When designing the
heating system, it should be borne in mind that special consum-
ers such as e.g. hot water preparation should also be considered
and dimensioned for low temperatures. Underfloor heating
systems (panel heating) are optimally suited for heat pump use
on account of the low flow temperatures (30 °C to 40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation because this increases the tempera-
ture difference, in turn reducing the COP.
Correct adjustment of the Heat pump manager is also important
for energy-efficient use of the heat pump. Further information can
be found in the Heat pump manager's operating instructions.
