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 Pro-
tocol, with a GWP of 1725 (GWP = Global
Warming Potential). If it escapes into the at-
mosphere, its impact is 1725 times stronger
than the natural greenhouse gas CO
2
.
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 re-
placed.
▶
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.
