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 REMS Frigo 2, check whether
voltage on the rating plate matches the mains voltage. On building sites, in a
wet environment, indoors and outdoors or under similar installation conditions,
only operate the REMS Frigo 2 on the mains with a fault current protection
switch (FI switch) which interrupts the power supply as soon as the leakage
current to earth exceeds 30 mA for 200 ms. Only use sockets/extension leads
with a functioning protected earth contact.
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. 15 – 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). Shortest freezing times will be achieved when the
hose connector at the deep-freezer head is pointing upwards.
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

4.2. Inspection/Repair
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
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 subjected to solar
radiation or hot air draughts. In parti cular, 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 powered by a battery
(button cell) which can be changed as required.
CAUTION
The deep-freezer heads and the refrigerant hoses attain temperatures of
–30°C (–22°F)! 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 (Fig. 3) are ball-park values and
apply at an ambient/water temperature of approx. 20°C and when the refrige-
rant is applied at the highest possible position of the deep-freezer head. 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.
NOTICE
Transport the apparatus only in an upright position, never while lying flat!
WARNING
Pull out the mains plug before maintenance work! Check hoses and deep-
freezer heads for damage before every use. Do no used damaged hoses and
deep-freezer heads.
Clean plastic parts only with the REMS CleanM machine cleaner (Art. No.
140119) or a mild soap and a damp cloth. Do not use household cleaners These
often contain chemicals which can damage the plastic parts. Never use petrol,
turpentine, thinner or similar products to clean plastic parts.
Make sure that liquids never get inside the electrical device.
WARNING
Pull out the mains plug before doing maintenance work! This work may
only be performed by qualified personnel.
