3.3 Coolants
The heat pump is delivered with an operational filling of
R 407 C coolant. This is a chlorine-free coolant which

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 emanat-
ing from leaks in the coolant circuit.
Risk to health! Avoid contact with the
skin and eyes. Escaping coolant can
cause freezing 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 unit contains R 407 C coolant. The
coolant must not be allowed to escape
into the atmosphere. R 407 C is a fluori-
nated, chlorine-free greenhouse gas that
has been included in 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.
Draining or filling with new coolant (see
identification plate for quantity) may
only be carried out via the service
valves. All warranties become void if any
approved replacement coolant other
than the R 407 C recommended by
Vaillant is used.
