Refrigeration cycle intervention
 Only allowed by refrigeration technical experts. Contact customer service.
 Take care in the event of accumulation of cooling agent vapours at ground level – lack of
oxygen – risk of suffocation!
 Smoking and unshielded flames prohibited!
 Always ensure the power is off in the system before intervention see above)!
First aid
 Use protective goggles to shield your eyes against exposure to liquid cooling agents!
In the event of eye contact with liquid cooling agent do not rub the eyes and avoid all eye aggra-
vation. Consult a physician immediately.
 First aid: Apply a few drops of sterile mineral oil to the eyes or a weak boric acid solution or
2% common salt solution. Subsequently rinse out eyes.
Attention: Please comply in full with the following safety
information in order to exclude the danger of property dam-
age and damage to the environment!
Disruptions
If the refrigerating system fails to operate
 check whether the current entry has been interrupted. This calls for troubleshooting by tech-
nical experts!
If both refrigerating clamps fail to ice over
 check whether the refrigerating machine is running and if the condenser is being aerated
adequately is not contaminated, ventilation slots not displaced). If this should be the case,
troubleshooting needs to be carried out by a technical expert cooling device constructor, re-
frigeration technician)!
If only one of the refrigerating clamps ices over
 hold both refrigerating clamps upright for about 10 minutes while the machine is running so
that any process oil that may have become displaced in the refrigerating clamps drains back
to the compressor. If this does not lead to a change, a technical expert should be asked to
carry out troubleshooting.
If the refrigerating system shuts down for no recognisable reason this could be due to
 unduly high process temperatures or electric currents as a result of excessively high or low
ambient temperatures
 inadequate air flow air grille displaced, condenser contaminated)
 electric failure.
Troubleshooting must be carried out by a technical expert if the equipment temperature was
maintained upon commissioning min. 16° C), the ambient temperatures are within the permissi-
ble limits and the air flow is correct.
In the event of a fire
 Shut down the refrigerating system and use a carbon dioxide or powder fire extinguisher to
fight the fire.
General information
 Only carry out freezing in compliance with the intended use described in the operating man-
ual.
 Do not obstruct the air circulation, i.e. do not close the lid and block the ventilation slots dur-
ing operation as otherwise the freezing process cannot be carried out properly.
 Protect cooling hoses and refrigerating clamps against damage.
 Only store, transport and operate the pipe freezing system in the installation position. Pro-
tect against impact, strong vibrations and falling. The system is suitable for portable use ac-
cording to class 7M2.
 The installation location must be dry and free from dust.

3 Scope of elivery, transport an storage
Scope of elivery:
Essentially, the ROFROST Turbo R290 28 UK pipe freezing system consists of the following
components or following accessories respectively:
• Electric refrigerating system consisting of:
Refrigerating aggregate including housing, carry handle, lid, plastic insert as receptacle for
the reducing inserts, shutdown switch and power cord
2 cooling hoses with refrigerating clamps evaporator system) and clamping screws with in-
tegrated thermometer
• Set of reducing inserts 8-10-12-15-22)
• 1 tin of heat-conductive paste
Transport an storage:
 Store the cooling hoses, refrigerating tongs and the reducing inserts in the portable housing.
 Only store in installation position i.e. upright) in a dry and dust-free environment at tempera-
tures between -10° C to 35° C.
 Protect against impact and vibration.
4 Function of the Unit
4.1 Commissioning
The equipment ROFROST Turbo R290 28 UK freezing system) must be tempered, i.e. have
adopted room temperature + 16° C up to a max. of 32° C) before commissioning.
 Shut down the heating circuit on which the piping is to be interrupted by means of an ice
plug. Shut down the heating and pump in good time in order to stop the water flow.
 Position the freezing system in such a way that the equipment ventilator motor does not
blow onto the pipes to be frozen, as they must be protected against warm air.
The fitted ventilator sucks in the air that is required for the liquefaction of the cooling agent and
cooling the compressor on the long side of the equipment and presses it out again on the top
side.
 Hold the refrigerating clamps upright and switch the system on for about 5 minutes so that
any oil that may still possibly be in the refrigerating clamps can drain back into the circuit.
Switch on by operating the rocker switch.

8 ENGLISH
Caution: During the freezing process make sure that all
the air grilles are not blocked as proper air circulation must
be guaranteed!
The ROFROST Turbo R290 28 UK is a “contact freezing unit“. The function of the unit can only
be guaranteed if there is proper heat-conducting contact between the refrigerating clamps and
the pipes that are to be frozen. Paint and contamination in the application range of the clamps
will extend freezing times; ideally, the pipe to be frozen should be metallic bright.
 Only apply the refrigerating clamps to the straight pipe sections. Badly distorted or out-of-
centre pipes are not suitable for freezing.
4.2 Application an replacement of the tools
The refrigerating clamps are designed for pipes with an exterior diameter of:
ROFROST Turbo R290 28 UK: 28 mm
Special reducing inserts are required in order to also be able to freeze pipes of a smaller diame-
ter see ill. A).
 Spread heat-conducting paste generously on the contact surfaces between the refrigerating
clamps, reducing inserts and pipes to avoid insulation bridges see ill. B-1).
Caution: Heat-conducting paste must be used for optimum
performance! Important information: The refrigerating
clamps and pipes must be protected against draughts dur-
ing the freezing process!
 Handle the reducing inserts and refrigerating tongs with care. Clean them with a dry cloth af-
ter use and store them in the lining provided to protect them against damage.
4.3 Operating
The ROFROST Turbo R290 28 UK is a compact ready-to-plug unit. It works with a hermitical
compression refrigerating system. Troublefree continuous operation for hours or days is possible
under supervision and within the prescribed ambient temperature range and voltage / frequency
in accordance with the technical data.
The simple clamping system of the refrigerating clamps ensures safe connection to the pipe.
 Press the clamp together with the appropriate insert onto the pipe to be frozen and tighten
by means of the fastening screw see ill. B-2).
Caution: Only tighten the fastening screw by hand!
 Remove superfluous heat-conducting paste!
We recommend greasing the screw as this makes it easier to release the refrigerating tongs af-
ter the freezing process!
Important information: During the freezing process a temperature difference between display
L) and display R) is possible. As a rule, however, this is compensated for in the minus range.
Furthermore, exterior factors can also play a part, e.g:
– Different output temperatures of the respective pipes due for freezing,
– Different pipe diameters,
– Different contacting of the refrigerating clamps on the pipe,
– Adverse effect of draughts.
 Do not switch the unit on until both refrigerating clamps have been secured firmly to the
pipes to be frozen see ill. B-3). The heating or pump must be switched off in good time in
order to stop the water flow in the pipe.

ENGLISH 9
Danger: Danger of frostbite! The metal parts of the re-
frigerating clamps have a temperature of approx. –30°C
during the freezing process. Only touch the refrigerating
clamps wearing gloves suitable for the cold!
 Open the circuit when the temperature is at < -5° C and the time has been reached accord-
ing to the table see ill. A).
The stated values are guideline values determined at a room temperature of 22° C.
4.4 Shut own
 Shut down the freezer system, allow the refrigerating clamps and hoses to defrost, remove
them from the pipe and clean.
 Hold the refrigerating tongs upright for about 5 minutes and switch the system back on so
that any oil that may still possibly be in the refrigerating tongs can find its way back into the
circuit.
 Shut down the system, remove the power plug and carefully store the hose assembly group
in the housing compartment
Caution: Do not bend or stretch the hoses!
5 Care an Maintenance
 Handle the equipment with care and consideration
 Avoid hard impact, vibrations and mechanical damage
 Only operate, transport and store the equipment in an upright installation position.
If, contrary to expectations, and in spite of careful handling a technical fault should occur, please
contact your dealer or the manufacturer dir.
The cooling circuit must only be opened by technical experts from ROTHENBERGER
Werkzeuge GmbH.
Once the ROTHENBERGER heat-conductive paste has been used up it can be re-ordered by
quoting order no. 62291.
6 Troubleshooting
Basic details can be found in the chapter on safety information.
In addition please also check:
– that adequate heat-conductive paste is applied for the contact between the refrigerating
clamps and the pipe or the reducing insert and the pipe,
– that the refrigerating tongs are attached to the pipes properly,
– that the water circuit is not flowing.
Among other things, additional influences can have an effect on the length of freezing time:
– wall thickness of the pipes,
– pipe material,
– contaminated water,
– outgoing temperature of the water to be frozen,
– ambient temperature e.g. solar irradiation),
– operating temperature of the equipment,
– bent or stretched refrigerating hoses.
The freezing parameters in the table are only reference guides and ROTHENBERGER
Werkzeuge GmbH does not accept responsibility for the variations in field use.
