1.2.7 Risk of death due to lack of safety
devices
A lack of safety devices (e.g. expansion relief
valve, expansion vessel) can lead to poten-
tially fatal scalding and other injuries, e.g. due
to explosions.
▶
Have your competent person check that
all required isolator devices are present in
your heating installation.
1.2.8 Preventing the risk of injury from
freezing as a result of touching
coolant
The heat pump is delivered with an oper-
ational filling of R410A coolant. This is a
chlorine-free coolant which does not affect
the Earth's ozone layer. R410A is neither a
fire hazard nor an explosion risk. Escaping
coolant may cause freezing if the exit point is
touched.
▶
If coolant escapes, do not touch any com-
ponents of the heat pump.
▶
Do not inhale any steam or gases that es-
cape from the coolant circuit as a result of
leaks.
▶
Avoid skin or eye contact with the coolant.
▶
In the event of skin or eye contact with the
coolant, seek medical advice.
