into the appliance.
The ventilation grille should be cleaned when it is
dirty.
Important:
If refrigerant should escape from the closed ref-
rigerant circuit of the
ROFROST TURBO II
, keep
it away from hot surfaces or fire.
Caution:
Formation of dangerous fumes. Danger
of poisoning!
When disposing of the
ROFROST TURBO II
, plea-
se ensure that the R404a refrigerant is removed
separately by a specialist firm.
Keep these operating instructions together with
the safety information in a safe place, and ensu-
re that personnel have read and understood them
before they use the
ROFROST TURBO II!

Placing in operation
4.1 Transport and storage
The cryogenic hoses, the freeze clamps and the
reduction inserts can be conveniently stored in
the portable case for transport and storage.
The
ROFROST TURBO II
should only be stored
in a dry place.
Transport and store the freezing appliance only
in an upright position. If it should tip over, stand
upright for a while before use.
4.2 Installing and setting-up
Switch off the central heating or pump in due time
to stop the water circulation.
Then set up the
ROFROST TURBO II
appliance
in such a way that the appliance’s ventilator motor
does not blow on the pipes which are to be fro-
zen, as these must be protected from draughts.
The built-in ventilator draws in air, which is requi-
red for the liquefaction of the refrigerant as well
as for cooling the compressor, at the long side of
the appliance and forces this out again at the top.
C a u t i o n :
a l w a y s l e a v e t h e c o v e r o p e n e d a n d
ensure that the ventilation grille is not obstruc-
ted during the freezing process, as the air must
be able to circulate freely.
The
ROFROST TURBO II
is a „contact freezing
appliance“, i.e. the appliance only works reliab-
ly, when there is a good heat conducting contact
between the freeze clamps and the pipes which
are to be frozen. Paint and contaminants in the
area of attachment of the tongs extend the free-
z i n g t i m e s ; i d e a l l y, t h e p i p e w h i c h i s t o b e f ro -
zen should be clean down to bare metal.
Furthermore, care should be taken that the fre-
eze clamps are only attached to a straight run of
pipework. Badly deformed or out-of-round pipes
are not suitable for freezing.
