▶
If you are going to be away during a cold
period, ensure that the heating installation
remains in operation and that the rooms
are sufficiently heated.
▶
You must observe the frost protection in-
structions.
1.2.13 Frost damage caused by a power
cut
During installation, your competent person
connected your product to the power mains.
If the power supply is cut, it is possible that
parts of the heating installation may become
damaged by frost. If you want to use an emer-
gency power generator to maintain the opera-
tional readiness of the product during a power
cut, note the following:
▶
Contact your competent person for advice
on installing an emergency power gener-
ator.
▶
Ensure that the technical values of this
generator (frequency, voltage, earthing)
match those of the power mains.
1.2.14 Malfunction caused by incorrect
system pressure
To avoid operating the system with too little
water and thus prevent resulting damage,
note the following:
▶
Check the system pressure of the heating
installation at regular intervals.
▶
You must observe the system pressure
instructions.
1.2.15 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
atmosphere, its impact is 1725 times stronger
than the natural greenhouse gas CO

.
Before the heat pump is disposed of, the
coolant it contains must be completely
drained into a suitable vessel so that it can
