The water (or other liquid) in the pipe can only be frozen when it is no longer
fl owing. All pumps must therefore be stopped and no liquid removed or allowed
to escape from the pipe. Before freezing, let the water cool down to room
temperature.
Fully open the cylinder valve. The amount of CO

temperature of –79°C and freezes the water within the pipe. After a brief period,
frost will form on the pipe in the vicinity of the freeze collars. If frost does not
form in accordance with time given in the table, then this indicates that the
liquid within the pipe is still fl owing (check that all pumps have been switched
off and prevent any removal or outfl ow of water) or the water is too warm. While
work is in progress, the fl ow of CO

Always ensure a suffi cient supply of refrigerant by providing a stand-by cylinder.
The only way to determine the amount of remaining CO
If it is necessary to change the cylinder during work, it is essential that this proce-
dure should be complete within 7 minutes to prevent the ice pack from melting.
Once work is complete, close the cylinder valve and wait until the pressure in
the high-pressure hoses has returned to normal. Remove the high-pressure
hoses. Once the ice pack has completely melted,
remove the handle pieces with injector from the freeze collar and remove the
freeze collar.
5. Procedure in Case of Trouble
Fault: Frost does not form on the pipe.
Cause:
● Freezing time still too short.
● Pumps not switched off, outfl ow of water.
● CO cylinder is empty or cylinder valve is not open. cylinder is empty or cylinder valve is not open.
2 2 2
● Choke in cylinder connector with T-distributor is blocked up.
● Filter in front of injector nozzle blocked up.
6. Disposal
ROLLER'S Polar may not be thrown into the domestic waste at the end of use
but must be disposed of properly by law.

be regarded as general guidelines and are valid for a water temperature of
approx. 20°C. The freezing times and refrigerant consumption values will there-
fore vary for higher temperatures. For freezing liquids in plastic pipes much
longer freezing times are generally required.
