1 Safety
1.1 Action-related warnings
Classification of action-related warnings
The action-related warnings are classified in
accordance with the severity of the possible
danger using the following warning signs and
signal words:
Warning symbols and signal words
Danger!
Imminent danger to life or risk of
severe personal injury
Danger!
Risk of death from electric shock
Warning.
Risk of minor personal injury
Caution.
Risk of material or environmental
damage
1.2 Required personnel qualifications
▶ Secure against being switched back on
again.
▶ Wait for at least 3 minutes until the con-
densers have discharged.
▶ Check that there is no voltage.
▶ Cover or insulate adjacent live parts.
1.3.3 Risk of death due to lack of safety devices
A lack of safety devices (e.g. expansion relief valve, expansion vessel) may lead to potentially fatal scalding and other injuries, e.g.
due to explosions. The schematic drawings
included in this document do not show all
safety devices required for correct installation.
▶ Install the necessary safety devices in the
system.
▶ Inform the operator about the function and
position of the safety devices.
▶ Observe the applicable national and inter-
national laws, standards and guidelines.
Improper work carried out on the product
may cause material damage to the complete
installation and, as a consequence, may even
cause personal injury.
▶ You should therefore only work on the
product if you are an authorised competent
person.
1.3 General safety information
1.3.1 Danger caused by improper operation
Improper operation may present a danger to
you and others, and cause material damage.
▶ Carefully read the enclosed instructions
and all other applicable documents, particularly the "Safety" section and the warnings.
1.3.2 Risk of death from electric shock
There is a risk of death from electric shock if
you touch live components.
1.3.4 Risk of being scalded by hot drinking water
There is a risk of scalding at the hot water
draw-off points if the hot water temperatures
are greater than 50 °C. Young children and
elderly persons are particularly at risk, even
at lower temperatures.
▶ Select the temperature so that nobody is at
risk.
1.3.5 Risk of injury or material damage due to incorrect handling of the product
Using the fins on the front side of the product
as conductors may lead to injuries (due to
falling) or to material damage.
▶ Do not use the fins as conductors.
1.3.6 Risk of material damage due to additional elements in the heating water
Before commencing work on the product:
▶ Disconnect the product from the power
supply (electrical partition with a contact
opening of at least 3 mm, e.g. fuse or
power switch).
Unsuitable frost and corrosion protection
agents may damage seals and other components of the heating circuit and may therefore also lead to leaks in the water outlet.
▶ Only add approved frost and corrosion
protection agents to the heating water.
0020154078_03 Envirosorb₃ Installation instructions 3
1 Safety
1.3.7 Risk of material damage caused by using an unsuitable tool
▶ Use the correct tool to tighten or loosen
screw connections.
1.3.8 Avoid environmental damage caused by escaping coolant
The heat pump contains R410A coolant.
The coolant must not be allowed to escape
into the atmosphere. R410A is a fluorinated
greenhouse gas covered by the Kyoto Protocol, with a GWP of 1725 (GWP = Global
Warming Potential). If it escapes into the atmosphere, its impact is 1725 times stronger
than the natural greenhouse gas CO2.
Before the heat pump is disposed of, the
coolant it contains must be completely
drained into a suitable vessel so that it
can then be recycled or disposed of in
accordance with the regulations.
▶ Ensure that only officially certified com-
petent persons with appropriate protective
equipment carry out maintenance work on
the coolant circuit or access it.
▶ Arrange for the coolant contained in the
product to be recycled or disposed of by
accredited specialists in accordance with
regulations.
▶ Only use coolant R410A.
▶ Only use a suitable R410A tool for the
filling, pressure measurement, vacuum
generation and discharge.
▶ Solder the lines using shielding gas. Check
the lines for leak-tightness using nitrogen.
▶ In the event of a repair or maintenance
work, fill the coolant circuit with liquid
coolant.
▶ If the coolant circuit is not leak-tight, check
which component must be repaired or replaced.
▶ Lower the negative pressure in the coolant
circuit to max. 10 mbar (1000 Pa).
▶ When filling the coolant circuit, observe the
values in the "Technical data" section.
1.4 Regulations (directives, laws, standards)

protection agent should be added to the heating water as
the heating water temperature may fall below the freezing point in the event of a power cut, which poses a risk
of frost to the heating installation.
Note
Operating the heat pump outside the application
limits results in the heat pump being switched off
by the internal control and safety devices.
3.2 Functionality
The product comprises the following circuits:
– The coolant circuit releases heat into the heating circuit
by means of evaporation, compression, condensation
and expansion
– The heating circuit
3.2.1 Heating mode
3 System overview
3.1 Safety devices
– The product can work at the following outside temperat-
ures:
Envirosorb
5
Heating mode −15 … 28 ℃ −20 … 28 ℃
Cylinder charging mode −15 … 46 ℃ −20 … 46 ℃
– If the product's coolant circuit pressure exceeds the max-
imum pressure of 4.15 MPa (41.5 bar), the high-pressure pressure switch switches the product off. Following a waiting period, the product attempts to start once
more. After three failed start attempts in succession, a
fault message is displayed.
– If the product is switched off, the crankcase housing
heating is switched on when the compressor outlet temperature reaches 7 °C in order to prevent possible damage caused by switching it back on.
– If the compressor inlet temperature and the compressor
outlet temperature are below 1 °C, the compressor does
not start up.
– A temperature sensor on the compressor outlet limits the
product's operation if the measured temperature exceeds
the maximum permissible temperature. The maximum
permissible temperature depends on the evaporation and
condensation temperature.
– The product measures the flow rate of the connected
heating circuit when starting up the product.
– If the heating circuit temperature falls below 3 °C, the
product's frost protection function is automatically activated as the heating pump is started. In addition, frost

5.1 Preparing for fitting and installation
5.1.1 Delivery, transport and positioning
5.1.1.1 Transporting the product
▶ During transport, do not tilt the heat pump
by any more than the maximum angle of
45°.
1. Use the transportation belt to carry the product to the
final installation site.
2. Only lift the product from the back and side where the
hydraulic connections are located.
3. When transporting the product using a hand truck, secure the product using a belt.
4. In order to avoid scratches and damage, protect the
sides of the product that come into contact with the
hand truck.
5.1.1.2 Unpacking the product
Warning.
Risk of injury from lifting a heavy weight.
Lifting weights that are too heavy may cause
injury to the spine, for example.
▶ When transporting the product, two
people should lift it.
▶ Observe the product weight stated in the
technical data.
▶ When transporting heavy loads, observe
the applicable directives and regulations.
1. Remove the accessory (2).
2. Remove the documentation supplied (1).
3. Remove the transport belt (4).
4. Carefully remove the packaging and padding without
damaging the product (3).
5. Remove the screws from the pallet at the front and rear
of the product.
Caution.
Risk of material damage due to incorrect
transportation.
Regardless of the mode of transport, the heat
pump must never be tilted by more than 45°.
Otherwise, this may lead to malfunctions in
the coolant circuit during subsequent operation. In the worst case scenario, this may lead
to a fault in the whole system.
