▶ 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

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.
