Installation instructions aroTHERM 0020217827_03
▶
Secure against being switched back on
again.
▶
Wait for at least 3 minutes until the capa-
citors have discharged.
▶
Check that there is no voltage.
1.3.4 Risk of death due to lack of safety
devices
The basic diagrams included in this docu-
ment do not show all safety devices required
for correct installation.
▶
Install the necessary safety devices in the
installation.
▶
Observe the applicable national and inter-
national laws, standards and directives.
1.3.5 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.
1.3.6 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.
1.3.7 Risk of material damage due to
additional elements in the heating
water
Unsuitable frost and corrosion protection
agents may damage seals and other com-
ponents of the heating circuit and may there-
fore also lead to leaks in the water outlet.
▶
Only add approved frost and corrosion
protection agents to the heating water.
1.3.8 Risk of material damage caused by
using an unsuitable tool
▶
Use the correct tool.
1.3.9 Avoid environmental damage caused
by escaping refrigerant
The heat pump contains the refrigerant
R410A. The refrigerant must not be allowed
to escape into the atmosphere. R410A is a
fluorinated greenhouse gas covered by the
Kyoto Protocol, with a GWP of 2088 (GWP
= Global Warming Potential). If this gas es-
capes into the atmosphere, its impact is 2088
times greater than the natural greenhouse
gas CO

.
Before the heat pump is disposed of, the re-
frigerant that is contained in it must be com-
pletely drained into a suitable vessel so that
it can then be recycled or disposed of in ac-
cordance with regulations.
▶
Ensure that only officially certified com-
petent persons with appropriate protective
equipment carry out maintenance work on
the refrigerant circuit or access it.
▶
Arrange for the refrigerant contained in the
product to be recycled or disposed of by
certified competent persons in accordance
with regulations.
▶
Use only R410A as the refrigerant.
▶
Only use a tool suitable for R410A 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 refrigerant circuit with liquid
refrigerant.
▶
If the refrigerant circuit is not leak-tight,
check which components must be repaired
or replaced.
▶
Lower the negative pressure in the refri-
gerant circuit to max. 10 mbar (1000 Pa).
▶
When filling the refrigerant circuit, observe
the values in the "Technical data" section.
