rine, salt, sewer gas, ue gases etc. may cause
damage leading to complete failure or even a
total write-o of the heating pump!
WARNING!
In the air outlet area the air temperature is
ca. 5 K below the ambient temperature. Un-
der certain climatic conditions, therefore,

Operating principle of heat
pumps
Heat pumps operate on the principle of a refrigerator:
the same technology, only with the opposite eect. 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 ground water. The extracted heat is con-
ditioned 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 he-
at pump can be utilized in new or existing heating sys-
tems.
Overview "Technical data/ scope of delivery".
Heat quantity recording
In addition to the proof of the unit's eciency, EEWaer-
meGalso meets the demand for a heat quantity recor-
ding (hereafter refered to as HQR). The HQR is manda-
tory with air/water heat pumps. With brine/ water and
water/water heat pumps, a HQR may only be set up
when a forward ow temperature of ≥ 35 °C has been re-
ached. The HQR must record the total warm energy re-
lease (heating and hot water) in the building. In heat
pumps with heat quantity recording, the analysis is con-
ducted by the regulator. The regulator displays the ther-
mal 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 wi-
th the control element of the heating and heat pump re-
gulator.
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
operates eciently and ecologically, the following are
especially important:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.
A lower ow temperature on the hot water side
increases the eciency of the system.
€ENERGY SAVING TIP
When letting in fresh air. do not leave windows
open for an extended period in order to save
energy and reduce 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 ab-
rasives, acids and/or chlorine. Such products would de-
stroy 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 regu-
lar maintenance.
According to EU regulation (EC) 517/2014, leak
inspections and maintenance of a log book are required
by law for certain heat pumps!
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 hea-
ting or cooling system technician.
It is a good idea to have a maintenance contract with a
specialist company. The company will conduct the re-
quired maintenance at regular intervals.
ATTENTION
Check regularly to ensure that the condensate
can drain out of the unit unobstructed. To this
end, regularly check the condensate pan in the
unit and the condensate drain to ensure that
they are clean / free from obstructions and clean
as needed.
CLEANING AND RINSING OF UNIT COMPONENTS
WARNING!
Unit components may be cleaned and rinsed
only by customer service personnel autho-
rized by the manufacturer. Use only liquids
recommended by the manufacturer.
Rinsing of the liqueer with chemical clea-
ning agents must be followed by neutraliza-
tion of residue and intensive rinsing with wa-
ter. 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 he-
ating and heat pump regulator.
Operating manual of the heating and heat
pump regulator.
DANGER!

Circulating pumps
ATTENTION
Always note the model.
Do not use regulated circulating pumps.
Circulating pumps and domestic hot water cir-
culation pumps must be multi-stage pumps.
Water heating
Water heating with the heat pump requires an additio-
nal hot water circuit, parallel to the heating circuit. Ma-
ke sure that the heating water charge is not channeled
through the buer tank of the heating circuit.
“Hydraulic connection” instructions.
Hot-water tank
If the heat pump will be used for heating hot water, you
must integrate special hot-water tanks in the heat pump
system. The storage volume must be sucient so that
the required hot water quantity is available even during
a power outage.
NOTICE.
The heat exchanger surface of the hot water
tank must be dimensioned so that the heating
capacity of the heat pump is transferred with
minimal spreading.
We oer a variety of hot-water tanks for you to choose
from. They are optimized for use with your heat pump.
NOTICE.
Integrate the hot-water tank in the heat pump
system corresponding to the hydraulic diagram
for your system.
“Hydraulic connection” instructions.
Pressure relief
Equip the heating circuit in accordance with local stan-
dards and directives with a safety valve and an expansi-
on tank.
Also install lling and emptying devices, shut-o de-
vices and non-return valves in the heating circuit.
Overow valve
Use an overow valve for tanks integrated in series to
ensure the minimum ow rate of the heating circuit vo-
lume ow through the heat pump. The overow val-
ve must be dimensioned so that the minimum ow ra-
te of the volume ow through the heat pump is ensured
when the heating circuit is shut o.
“Set the overow valve”, page 26.
Buer tank
The hydraulic connection of the heat pump requires a
buer tank in the heating circuit. It ensures a minimum
operating time of the heat pump when the heating cir-
cuit valves are closed. The required volume of the buer
tank is calculated based on the following formula:
VBuffer tank =
minimum ow rate of heat circuit volume ow / hour
10
For the minimum ow rate of the heat circuit vo-
lume ow, see overview “Technical data / Scope
of delivery”, “Heating circuit” section.
