WARNING!
The gaseous refrigerant is heavier than
air. In pits or in badly ventilated rooms
it can collect in high concentrations.
Breathing in high concentrations of
gaseous refrigerant leads to feelings
of faintness and suffocation. Toxic
gases can be formed if gaseous refrig-
erants come into contact with open fire
or hot objects.
When working on the refrigerant
circuit, ensure that the workplace is
well ventilated.
If necessary, before starting work,
evacuate the refrigerant system
completely.
Never carry out work on the refrig-
erant circuit in closed rooms or work
pits.
Do not let refrigerant come into
contact with open fire, embers or hot
objects.
Never allow coolant to escape into the
atmosphere (forms high concentra-
tions).
After removing the service pipes from
the filling connections, carry out a
leakproof test on the refrigeration
system. Refrigerant can escape
through leaks.
