General Power Tool Safety Warnings
WARNING
Read before use!
To reduce the risk of injury, the user must read and understand the instruction
manual.
The device has been built and operates safely in accordance with the state of the
art and the recognised rules of safety. Nevertheless dangers for the user or third
parties or material damage may arise from improper use or use not for the intended
purpose. Therefore read and follow the safety instructions!
Keep all safety rules and instructions for the future.
Only use the device for the intended purpose and under observance of the general
safety and accident prevention regulations.
A) Work place
●
Keep the work place tidy. Untidiness can cause accidents.
●
Avoid dangerous ambient infl uences (e.g. infl ammable liquids or gases).
●
Keep children and other persons away when using the device. Distractions can
lead to you losing control of the tool.
●
Make sure that the work place is well lit.
●
Make sure you are standing safely during work.
●
All unauthorised modifi cations to the device are prohibited for safety reasons.
●
Change worn parts immediately.
B) Safety of persons
●
Only employ trained personnel. Youths may only operate the device if they are
over 16 years of age, it is essential to achieve their training goal and they are
supervised by a specialist.
●
Wear tightly fi tting clothing, tie loosely hanging hair, take off jewellery and similar.
●
Use personal safety equipment (protective glasses, gloves).
●
Only use genuine accessories and spare parts for your own safety, to assure
proper functioning of the device and to uphold your warranty rights.
Special safety instructions for handling carbon
dioxide CO
2
WARNING
●
Inhalation of CO
2
in concentrated form is dangerous to the health. Therefore the
breathing air may not contain greater concentrations of CO
2
.
There is danger
of suffocation!!!
●
If a CO
2
system or a defective safety valve leaks CO
2
, this must be allowed to
escape into the outside air immediately. Submerged rooms (pits, shafts, base-
ments) must be evacuated immediately.
●
Only work in a well aired environment. CO
2
is non-toxic and non-fl ammable but
heavier than air. It therefore gathers near the fl oor and displaces the air if there
is no adequate ventilation.
Danger of suffocation!
WARNING
●
Work with naked fl ames may not be carried out closer than 60 cm from the
freezing point.
●
Do not hit freezed collars with tools (danger of breakage).
●
Keep other persons and especially children, also animals away. Dry ice causes
burns in contact with the skin. Do not dispose of residue ice from collars care-
lessly at the end of work but throw it in the waste bin.
WARNING
Handling CO
2
cylinders
●
Unauthorised refi lling of CO
2
from one gas cylinder into another is a high safety
risk and must be performed by appropriately trained staff of an authorised fi lling
company.
●
CO
2
cylinder valves frequently have overpressure protection in the form of a
rupture disc which is fi xed to the valve by a union nut. This device may
never
be
never be never
manipulated in any way to avoid unwanted and dangerous escaping of CO
2
.
●
CO
2
ice can be dangerous in many ways. There is a danger of cold burns if the
emerging jet comes into contact with the human skin.
●
CO
2
cylinders with dip tubes are clearly labelled as such by the fi lling company
and have a
red
valve hand wheel.
Drawing from CO
2
cylinders with dip tubes
●
CO
2
must be drawn from the CO
2
cylinder in a liquid state is order to produce
CO
2
ice (dry ice). Therefore only use CO
2
cylinders with a dip tube. Do not attach
a pressure regulator to the cylinder. Keep the cylinder in a secure, upright posi-
tion.
●
Due to technical reasons the CO
2
cylinder can never be fully emptied. Never
manipulate nozzles, collars or valves including cylinder valves.
WARNING
●
The drawing device must therefore be pressure-proof and suitable for liquid CO
2
.
For example, it could be
fatal
to connect a CO
2
cylinder with dip tube without or
without pressure regulator to a beer barrel. The beer barrel might not be able to
withstand the evaporating CO
2
liquid and would burst.
●
A frozen cylinder valve could prevent it from being closed. For safety reasons,
you must wait until the valve has thawed. A cylinder cap may not be screwed on
because this could build up pressure due to the dry ice and cause a high injury
risk during handling.
WARNING
Transport of CO
2
gas cylinders
●
Pressur
ised gas cylinders should only be transported with cylinder trolleys or in
case of sma
ll cylinders in suitable cariers or in the cylinder pallet. Do not hang
pressuri
sed gas cylinders to a crane by the valve protection (e.g. protective cap
or cage) for transport. The valve protection devices are designed exclusively for
protection of the valve and may not be used for lifting with a crane or lifting devices
(e.g. chains).
Storage of CO
2
gas cylinders
●
A risk assessment must be made before emptying pressurised gas cylinders.
●
Pressurised gas cylinders connected for emptying must always be secured against
falling over.
●
Before emptying pressurised gas cylinders, it must be ensured that the gas cannot
fl ow back into the pressurised gas cylinders from the pipe system.
●
Follow the safety instructions of the CO
2
gas manufacturer.
● Observe and follow the valid national safety conditions, rules and regula-
tions for the place of application.

1. Technical Data
Use for the intended purpose
WARNING
REMS Eskimo is intended for freezing unemptied pipes with carbon dioxide (CO
2
)
refrigerant.
All other uses are not for the intended purpose and are therefore prohibited.
1.1. Scope of Supply
Pipe freezer, 2 freeze collars each Ø 1/8“ – 2“, Ø 10–60 mm (10 sizes), bottle
connection with T-distributor, closing nut, 2 handle pieces with injector nozzle,
2 high-pressure hoses, operating instructions, plastic case.
1.2. Working range
Liquids of all types such as water, milk, beer etc. in pipes made from steel,
copper, cast iron, lead, aluminium, plastic etc. Pipe sizes ⅛ –
2"
respec tively
10 – 60 mm.
The ice pack which forms in the pipe is capable of withstanding a pressure of
approx. 500 bar.
1.3. Refrigerant
Carbon dioxide (CO
2
), commercially available in cylinders of different sizes. It
is best to purchase large cylinder sizes.
1.4. Noise data
Emission at workplace 75 dB (A).
2. Preparations for Use
Remove the seal from the CO
2
cylinder. Screw connector with T-distributor to
cylinder valve (right-hand thread). Screw high-pressure hoses to the T-distrib-
utor. Screw on the handle piece with injector nozzle to the high-pressure hoses
(Fig. 1). Choose freeze collars which correspond to the size of the pipe to be
frozen. Place the freeze collars on the pipe and secure by tightening the screws
evenly to give a fi rm but not overtight hold (Fig. 2). Turn and, at the same time,
push each handle piece with injector nozzle into the bore of the freeze collar
until it is completely inserted and resting against the stop (Fig. 3).
If one only operates with one collar, the free side of the T-distributor has to be
closed by the closing nut. If a 3. or further freezing points are required, additional
T-distributors (accessory) can be connected to the T-distributor.
3. Operation
WARNING
CO
2
displaces air! Do not use REMS Eskimo in submerged rooms (pits, shafts,
basements).
Danger of suffocation!
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
2
required is controlled auto-
matically. The liquid CO
2
expands in the injector and forms dry ice with a
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
