Coolants

The heat pump is delivered with an operational filling of
R 407 C coolant. This is a chlorine-free coolant which
does not affect the Earth's ozone layer. R 407 C is neit-
her a fire hazard nor an explosion risk.
However, maintenance work and interventions into the
coolant circuit may only be undertaken by an expert
technician with appropriate protective equipment.
d Danger!
R 407 C coolant!
Do not inhale gases or vapours emana-
ting from leaks in the coolant circuit.
Risk to health! Avoid contact with the
skin and eyes. Escaping coolant can
cause frostbite if the exit point is
touched! R 407 C coolant presents no
danger in normal use and under normal
conditions. With improper use, however,
it can cause injury and damage.
a Caution!
This appliance contains R 407 C coolant.
The coolant must not be allowed to es-
cape into the atmosphere. R 407 C is a
fluorinated greenhouse gas covered by
the Kyoto Protocol, with a GWP of 1653
(GWP = Global Warming Potential).
Before the appliance 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.
The relevant work in connection with the
coolant may only be carried out by offi-
cially certified specialists.
Coolant (see identification plate for
quantity) may only be drained off and
fresh coolant may only be added via the
service valves. All warranties become
void if any approved replacement coolant
other than the R 407 C recommended by
Vaillant is used.
