g) Secure the workpiece. Use clamps or a vice to hold the workpiece. This is safer
than holding it with your hand, and also it frees both hands to operate the equipment.
h) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power
tool, taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could result in
a hazardous situation. All unauthorised modifications to the power tool are
prohibited for safety reasons.
E) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.
b) Comply with maintenance instructions and instructions on tool replace-
ments.
c) Check mains lead of power tool regularly and have it replaced by a qualified
expert or an authorised ROLLER after-sales service facility in case of
damage. Check extension cable regularly and replace it when damaged.
Specific Safety Warnings
WARNING
● Wear gloves suitable against cold temperatures.
● Ice causes burns upon contact with skin. After work is finished, let deep- freezer
heads thaw out.
● Do not bend or twist hoses or subject them to tensile stress. This can lead to
leaks.
● Do not open up the refrigerant circuit. The apparatus contains the refrigerant
R-404 A in a closed circuit. Should refrigerant leak out in the event of defective
apparatus (e.g. breakage of a refrigerant hose), then the following must be taken
into consideration:
– Do not inhale: Get those affected into the fresh air and let them rest. Should
their breathing stop, use artificial respiration and call a physician.
– After contact with the skin: Thaw out or wash off affected portions of skin
with warm water.
– After contact with eyes: Rinse out thoroughly for 10 minutes with clean water;
call a physician.
– After swallowing: Do not induce regurgitation. Wash out mouth with water,
drink a glass of water. Go to a physician.
– Notice for physician: Do not administer any drugs of the Ephedrine / adre nalin
group.
DANGER
In case of thermal decomposition of the refrigerant (e.g. fire) highly noxious
and corrosive vapours are generated!
● Observe safety tips for refrigeration systems.
● When scrapping the apparatus, dispose of the refrigerant properly.
● Refrigerant may not be allowed to get into sewers, basements or work pits.
Refrigerant vapours may create a suffocating atmosphere.

Weighted effective acceleration reading
The indicated weighted effective value of acceleration has been measured
against standard test procedures and can be used by way of comparison with
another device. The indicated weighted effective value of acceleration can also
be used as a preliminary evaluation of the exposure.
CAUTION
The indicated weighted effective value of acceleration can differ during opera-
tion from the indicated value, dependent on the manner in which the device is
used. Dependent upon the actual conditions of use (periodic duty) it may be
necessary to establish safety precautions for the protection of the operator.
2. Preperations for Use
2.1. Electrical Connection
WARNING
Note the mains voltage! Before connecting the ROLLER'S Elektro-Freeze 2,
check whether voltage on the rating plate matches the mains voltage. At work
sites, in damp surroundings, in the open or in the case of comparable types of
use, only operate the equipment off the mains using a 30 mA fault current
protected switch (FI breaker).
Deep freezing occurs by means of a transfer of refrigeration from the deep-
freezer heads to the outer surface of the tubing. To ensure good contact
transition, paint, rust or other pollutants should be removed from the tubing.
Deformed tubes cannot be frozen up.
The water (or other liquid) in the tubing can only freeze up if there is no flow,
i.e. pumps should be turned off, water removal should be avoided. Cool off
water in the heating tubes to ambient temperature before deep freezing.
2.2. Mounting of the deep freeze heads
With tube sizes ¼ – 1" resp. 14 – 35 mm the deep-freezer heads are placed
directly against the tube (Figure 1). Fasten deep-freezer heads with the tightening
strap (Figure 2). Shortest freezing times will be achieved when the hose
connector at the deep-freezer head is pointing upwards.
2.3. Using the deep freezer inserts
For tube sizes ⅛" (10, 12 mm), 1¼" (42 mm), 1½", 54 mm, 2" (60 mm) deep-
freezer inserts (accessories) are required (Figure 1). The latter are placed in
the deep- freezer heads. Each application can be seen in the table (Fig. 3).
Fasten deep-freezer heads with deep-freezer inserts to the tube with the
tightening strap (Figure 2).
3. Operation
Turn the apparatus on only if the deep-freezer heads have been mounted. For
improving refrigeration transfer from the deep freezer heads to the tube, during
the deep freezing process water should be sprayed between the deep freezer
head and the tube (Figure 2) several times with the water squirt bottle. Impor-
tant: Mount deep-freezer heads and apply water by spraying. When deep
freezing begins, water should be sprayed intensively in order to fill the gap
between the deep-freezer head/insert and the pipe. Spray water onto both
131011 freezing points alternating from one to the other until a closed ice layer has
131110 been formed. This can take up to 10 minutes for large pipes. After that no more
131155 spraying is needed. If not followed, longer deep-freeze times apply or the pipe
131156 does not freeze despite frost formation on the deep-freeze heads. Should this
131157 frost formation not occur within the period given in the table, then this strongly
131158 suggests flowing water in the tubing or that the tube contents are hot. Where
131160 applicable, pumps should be turned off, prevent water leakage, let water cool
131115 off. In addition, take care that the deep- freezer heads are not subjected to solar
131104 radiation or hot air draughts. In parti cular, air emissions from the apparatus
093010 valves should not be allowed to blow on the deep-freezer point.
