Important Information
GGeenneerraall
• Ultra Deep Freezers of the UF-series are designed
to ensure the structure-maintaining long-term
storage of valuable preparations at very low
temperatures. The units are not intended to be
used for cooling of foodstuffs.
• Before using the unit, read these operating
instructions carefully, including all the
information on operating safety, use and
maintenance.
• Keep these operating instructions ready at hand
and leave them with the machine, so that all
users can find out about the functions and safety
regulations.
• Ensure that there is sufficient room around the
unit for air circulation. Please refer to the
installation information regarding this point.
SSaaffeettyy
• All installation work and adjustments to the unit
must only be carried out by qualified personnel.
Work performed by persons with insufficient
technical knowledge may adversely affect the
performance of the unit or cause physical injury
or damage to the equipment.
• The units must only be used by adults. Do not
allow children to play with the units or touch the
controls.
• The inside of the unit and the stored products are
very cold. To protect against burning, always wear
gloves while working on it.
• All servicing and repairs must only be carried out
by a qualified customer service engineer. Only
genuine spare parts must be used.
• Ensure that the connecting cable is not squeezed
or bent when the unit is being installed or moved.
• Before cleaning or carrying out maintenance
work, always switch the machine off and
disconnect the mains plug. Always pull the plug
and never the cable. If the plug is not accessible,
switch off at the safety device.
• The unit's cooling system contains refrigerant.
Both the unit and the products stored inside can
be severely damaged if this system starts to leak.
Make sure, therefore, that no sharp or pointed
objects come into contact with the cooling
system..
• The sound intensity level produced by the
equipment is lower than 70 dBA (measured in a
distance of 1 meter).
TTrraannssppoorrtt
• Check whether the unit has been delivered
undamaged. If you find that damage has occurred
in transit, immediately contact the delivery
service or relevant sales outlet, submitting the
delivery note or proof of purchase.
• Do not operate a unit that has been damaged in
transit! If you are unsure, contact your sales
outlet and ask them.
• The unit must be transported in an upright
position only (maximum inclination 45°).
• Follow the instructions for transport and storage
of the product marked on the packing:
EEnnvviirroonnmmeennttaall PPrrootteeccttiioonn
• Make your contribution to saving the
environment. Bear in mind that orderly and
proper disposal is required. Packaging materials
and devices are always recyclable and should be
taken for recycling.
• Before scrapping an old unit, remove the door so
that children cannot lock themselves inside while
playing.
• Before scrapping the unit, arrange for the lead
accumulator to be removed and disposed of
separately.
• When disposing of the unit, make sure that it
does not get too hot, as combustible gas would
cause the insulating foam to froth up.
