parts, breakage of parts, mounting, and any other condition that may affect
the power tool's operation. A guard or other part that is damaged should be
properly repaired or replaced by an authorised service facility unless other-
wise indicated in the operating instructions. Have defective switches replace
by an authorised service facility. Do not use the unit if the switch does not
turn it on and off.
· Warning
Only use genuine spare parts and accessories, for personal safety reasons,
to ensure correct operation of the machine. The use of other accessories
or attachments involves a risk of injury.
· Have your unit repaired by an authorised service facility
This unit complies with the relevant safety. All maintenance and repair work,
particularly when involving the electrical systems, must be performed only
by specialist personnel or by persons familiar with the machine and by using
original spare parts, otherwise injuries may result to the user. All unautho-
rised modifications of the machine are prohibited for safety reasons.

Specific Safety Instructions

· 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 refri-
gerant R 404A 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 /
adrenalin group.
Attention: 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.

2. Preparations for Use

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.
2.1. Mounting of the deep freeze heads
With tube sizes 1 / –1” resp. 14–35 mm the deep-freezer heads are placed
4
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.
2.2. Using the deep freezer inserts

For tube sizes 1 /

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). Fa-
sten deep-freezer heads with deep-freezer inserts to the tube with the tigh-
tening 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. Im-
portant: 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
freezing points alternating from one to the other until a closed ice layer has
been formed. This can take up to 10 minutes for large pipes. After that no
more spraying is needed. If not followed, longer deep-freeze times apply or
the pipe does not freeze despite frost formation on the deep-freeze heads.
Should this frost formation not occur within the period given in the table, then
this strongly suggests flowing water in the tubing or that the tube contents are
hot. Where applicable, pumps should be turned off, prevent water leakage, let
water cool off. In addition, take care that the deep-freezer heads are not sub-
jected to solar radiation or hot air draughts. In particular, air emissions from the
apparatus valves should not be allowed to blow on the deep-freezer point.
As accessories, LCD digital thermometers are available which can be inserted
into pockets on the tightening strap and which facilitate assessment of the deep-
freezer point's condition. The thermometers are driven by a battery which can
be replaced as needed.
Attention: The deep-freezer heads and the refrigerant hoses attain tempera-
tures of –30°C. Wear suitable gloves against cold temperatures.
According to the deep-freeze times indicated in the Table (Figure 3), repair
work can be done on the tubing. Before beginning repair work, check if the
tubing has depressurised. For this purpose, open any eventual let-off valves
or loosen a fastener. Do not turn apparatus off during repair process.
The deep-freeze times indicated in the Table (Figure 3) are ball-park values
and apply at an ambient / water temperature of about 20°C. At higher ambient
/ water temperatures, the time periods are accordingly extended. With plastic
tubing depending on the material used, substantially higher deep-freeze times
must be expected.
After completion of work, turn the apparatus off. Remove the plug and let deep-
freeze heads thaw out. Wear suitable gloves against cold temperatures. Detach
the tightening strap, deep-freezer heads and, where applicable, deep-freezer
inserts only after complete thawing in order to avoid damage to the apparatus.
Do not bend or twist hoses or subject them to tensile stress. This can lead to
leakage from the apparatus.
Transport the apparatus only in an upright position, never while lying flat!
