2.1. Electrical Connection
WARNING
Note the mains voltage! Before connecting the REMS Frigo 2 F-Zero, check
whether voltage on the rating plate matches the mains voltage. Only connect
REMS Frigo 2 F-Zero of protection class to a socket/extension lead with a func-
tioning protective contact. On building sites, in a wet environment, indoors and
outdoors or under similar installation conditions, only operate the REMS Frigo 2
F-Zero on the mains with a fault current protection switch (FI switch) which inter-
rupts the power supply as soon as the leakage current to earth exceeds 30 mA
for 200 ms.
2.2. Preparing the pipe
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 fl ow,
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.
2.3. Assembly of the deep-freezer heads and deep-freezer inserts
For pipe sizes ¼ –1" or 14 – 35 mm, the deep-freezer heads are applied directly
to the pipe (Fig. 1). For pipe sizes ⅛" (10, 12 mm), 1¼" (42 mm), 1½", 54 mm,
2" (60 mm), deep-freezer inserts (accessories) are required (Fig. 1). These are
inserted in the deep-freezer heads. See the table (Fig. 3) for the respective use.
Fix deep-freezer heads, with deep-freezer inserts and LCD digital thermometer
if necessary with a tensioning strap. The fastest freezing times are achieved
when the hose connection on the deep-freezer head is facing upwards (Fig. 2).

NOTICE
Freezing times depend on the ambient temperature, water temperature, pipe
size, pipe material, correct position in the deep-freezer head and the correct
deep-freezer inserts. The freezing times apply at an ambient/water temperature
of approx. 20°C. Higher ambient/water temperatures prolong the time accord-
ingly. Much longer freezing times can sometimes be expected with plastic pipes,
depending on the material.
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 fi ll the gap freezing begins
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 fl owing 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.
The scope of supply includes LCD digital thermometers which can be hung
onto the clamping bands and make it easier to assess the condition of the
freezing point. The thermometers are powered by a battery (button cell) which
can be changed as required.
CAUTION 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.
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 fl at!
Notwithstanding the maintenance described below, it is recommended to send
in the electrical device to an authorised REMS contract customer service
workshop for inspection and periodic testing of electrical devices at least once
a year. In Germany, such periodic testing of electrical devices should be
performed in accordance with DIN VDE 0701-0702 and also prescribed for
mobile electrical equipment according to the accident prevention rules DGUV,
regulation 3 "Electrical Systems and Equipment". In addition, the respective
national safety provisions, rules and regulations valid for the application site
must be considered and observed.
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 qualifi ed personnel.
