4.3 Use and change of tools
The freeze clamps are designed for pipes with an
e x t e r n a l d i a m e t e r o f 2 . 1 / 8 " o r 6 0 m m . S p e c i a l
reduction inserts (fig. 1) are required for freezing
pipes with a smaller diameter. Generously coat

pound to avoid insulation by-passing and achie-
ve optimum thermal conductivity and conducting
capacity between the freeze clamps (a), reduc-
tion inserts (b/d) and pipes (fig. 2).

the best possible results!
Treat the precision-made, accurate-to-size reduc-
tion inserts and freeze clamps with care! Clean
them after use with a dry cloth and replace in the
insets provided to prevent damage.
Rags soiled with heat transfer compound can be
disposed of without problem as normal waste.

Taking out of service

After the work has been completed, pull out the
appliance plug from the mains and allow the fre-
e z e c l a m p s a n d h o s e s t o d e f ro s t , b e f o re y o u
remove them from the pipe to clean them.
Caution: do not kink or stretch hoses!

led cooling circuit on the compression principle.
Continuous operation over several hours or days
presents no problems.
The simple clamping system of the freeze clamps
ensures a firm attachment to the pipe.
For attachment, press the clamp and the appro-
priate inset against the pipe which is to be frozen
a n d s e c u re w i t h t h e f i x i n g s c re w. R e m o v e a n y
superfluous heat transfer compound.
Caution: tighten the fixing screw only by hand!
In addition, it is recommended that the screw be
greased, as this enables the clamps to be deta-
ched more easily after the freezing process.
Working near a wall or in a constrained position
is made possible by the favourable width across
cor ners. The freeze clamps are connected to a
flexible, diffusion resistant mono-hose system.
As a result, the ROFROST TURBO II is extreme-
ly handy, and the 2.5 m long hoses also ensure an
ample working area.
Important:
There can be a temperature difference from dis-
play (L) to display (R) during freezing; this, howe-
v e r, i s n o r m a l l y c o m p e n s a t e d f o r i n t h e m i n u s
range.
In addition, external factors may also play a role,
e.g.:
- variable initial temperatures of the respective
pipes to be frozen
- variable pipe diameters
- variable contacting of the freeze clamp to the
pipe
- adverse effect of draughts
S w i t c h o n t h e a p p l i a n c e o n l y a f t e r b o t h f re e z e
clamps are securely attached to the pipes which
are to be frozen. The central heating system or
the pump must be switched off in due time to stop
the water circulation in the pipes.
The metal parts of the freeze clamps reach a tem-
perature of approx. -30°C during the freezing pro-
cess. To prevent frost-bite, the freeze clamps may
only be handled using suitable thermally insula-
ted gloves.

table (approximate values) has elapsed (fig. 4).
The values stated are approximate values, which
were determined at an ambient temperature of
22°C.
7. Maintenance
The ROFROST TURBO II is designed for use on
construction sites and is therefore contained in
a robust sheet steel case. Nevertheless, handle
it carefully. The technical components inside the
appliance are sensitive to rough treatment. As a
result, never drop the appliance or allow it to fall
over.
Should, contrary to expectations, a technical fault
occur in spite of careful handling, please contact
the dealer or the manufacturer directly.

When the ROTHENBERGER heat transfer com-
pound has been used up, a further supply can be
ordered quoting order no. 6.2291.
