conform to the state of the art, all relevant DIN/VDE
regulations and all relevant safety regulations.
Every person who performs work on the unit must have
read and understood the operating manual prior to
starting any work. This also applies if the respective per-
son has already worked with such a unit or a similar unit
or has been trained by the manufacturer.
Every person who performs work on the unit must
comply with the applicable accident prevention and safety
regulations. This applies in particular to the wearing of
personal safety gear.
DANGER!

ly by qualied electricians.
Before opening the unit, disconnect the
system from the power supply and secure
it from being switched back on!
DANGER!
Only qualied technicians (trained heating,
cooling, refrigerant and electrical techni-
cians) may perform work on the unit and
its components.
WARNING!
Observe safety labels on and in the unit.
WARNING!

Leaking refrigerant could result in
personal injury or material damage.
Therefore:
– Shut down unit.
– Notify the manufacturer’s authorised
service centre.
ATTENTION
For safety reasons:
Never disconnect the unit from the power sup-
ply, unless the unit is being opened.

ATTENTION
Install the heat pump only outdoors and operate
only with outside air as the heat source. Do not
restrict or block the air-conducting sides.

spective model.
WARNING!
Never switch on unit if air ow bafes on
the unit are removed.
ATTENTION
The integration of the heat pump in ventila-
tion systems is not permissible. The use of the
cooled air for cooling purposes is not permitted.
WARNING!
In the air outlet area the air temperature
is ca. 5 K below the ambient temperature.
Under certain climatic conditions, there-
fore, an ice layer can form in the air out-
let area. Install the heat pump so that the
air blower does not blow in the direction
of footpaths.

Operating principle of heat
pumps
Heat pumps operate on the principle of a refrigerator:
the same technology, only with the opposite effect. The
refrigerator extracts heat from foods, which is released
into the room through ns on the back.
The heat pump extracts heat from our environment: air,
earth or water. The extracted heat is conditioned in the
unit and supplied to the heating water. Even when it is
extremely cold outside, the heat pump draws enough
heat to heat a house.
Example: drawing of a brine/water heat pump with oor
heating:
4/4= usable energy
approx. 3/4= environmental energy
approx. 1/4= external
electrical energy
Area of utilisation
Taking into consideration the ambient conditions, limits
of application and the applicable regulations, every heat
pump can be utilised in new or existing heating systems.
Overview “Technical data / scope of delivery”.
Heat quantity recording
In addition to verication of the unit's efciency,
EEWaermeG also meets the demand for a heat quantity
recording (hereafter referred to as HQR). The HQR
is mandatory with air/water heat pumps. With brine/
water and water/water heat pumps, an HQR may only
be set up when a forward ow temperature of ≥ 35 °C
has been reached. The HQR must record the total warm
energy release (heating and hot water) in the building. In
heat pumps with heat quantity recording, the analysis is
conducted by the regulator. The regulator displays the
thermal energy that is exchanged from the heating system
in kWh.
Operation
Your decision to purchase a heat pump or a heat pump
system is a long-term contribution to protecting the en-
vironment through low emissions and reduced primary
energy use.
You can operate and control the heat pump system with
the control element of the heating and heat pump regu-
lator.
NOTICE
Make sure that the control settings are correct.
Operating manual of the heating and heat pump
regulator.
To ensure that your heat pump or heat pump system op-
erates efciently and ecologically, the following are espe-
cially important:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.
The lower the ow temperature on the hot wa-
ter side, the more efcient the system.
€ENERGY SAVING TIP
Do not leave windows open continuously;
ventilate by opening windows wide for a
short time as this saves energy and reduc-
es your heating costs.

Care of the unit
The outer surfacesof theunit can be cleaned with a damp
cloth and household cleaning products.
Do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy the surfaces and could also damage the technical
components of the unit.
Maintenance of the unit
The cooling circuit of the heat pump requires no regular,
technically-qualied maintenance.
According to EU regulation (EC) 842/2006 of May 17,
2006, leak inspections and maintenance of a log book
are required for certain heat pumps!
The criteria for conducting leak inspections and
maintaining a log book are based on the hermetic
impermeability of the cooling circuit and the refrigerant
capacity of the heat pump! No log book is required for
heat pumps with a refrigerant capacity of < 3kg. With all
other heat pumps, the log book is included with all other
delivered materials.
Log book for heat pumps, Section “Information
on use of the log book”.
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps, l-
ters, dirt traps) should be inspected as well as cleaned as
needed – at the very least annually – by a qualied heat-
ing or cooling system technician.
The intake and blow-out openings must be inspected for
dirt at regular intervals (depending on the installation lo-
cation) and cleaned, if necessary.
ATTENTION
Regularly check to ensure that the condensate
can drain out of the unit unobstructed. To this
end, check the condensate pan in the unit as well
as the condensate drain on a regular basis to en-
sure that they are clean / free from obstructions;
clean as needed.
Icing of the protective grating
When temperatures fall below freezing and high levels
of humidity are present, ice can form on the protective
grating of the air ow bafes. In order to ensure
problem-free operations, the ice must be removed on a
regular basis.
It is a good idea to have a maintenance contract with a
heating installation company. The company will conduct
the required maintenance at regular intervals.
CleaningandFlushingunitComponents
WARNING!
Unit components may be cleaned and
ushed only by customer service person-
nel authorised by the manufacturer. Use
only liquids recommended by the manu-
facturer.
Flushing of the condenser with chemical
cleaning agents must be followed by
neutralisation of residue and intensive
ushing with water. Always observe the
technical data of the manufacturer of the
heat exchanger.
Malfunctions
In the event of a malfunction, you can detect the cause of
the malfunction via the diagnostic program of the heating
and heat pump regulator.
Operating manual of the heating and heat pump
regulator.
DANGER!
Service and repair work on the compo-
nents of the unit may be performed only by
customer service personnel authorised by
the manufacturer.

DANGER!
The unit can tip when being removed from
the wooden pallet and during transport!
This can result in personal injury and dam-
age to the unit.
– Take suitable precautionary measures
to eliminate the danger of tipping.
DANGER!
Make sure to secure unit against slipping
during transport.
ATTENTION
Never use components and hydraulic connec-
tions on the unit for purposes of transport.
ATTENTION
Do not damage the hydraulic connections under
any circumstances.
ATTENTION
Do not tilt the unit more than a maximum of 45°
