• Avoid long door openings. To prevent that the
inner temperature rises to high during loading,
only one interior flap should be opened at a time.
• The air circulation at the inner walls must not be
obstructed.
• The loading must not exceed the storage areas.
• Remove any frost or ice on container and door
gasket regularly using the provided icescrapper.
• Make sure that the loading does not touch the
reference bottle of the display sensor.
• Do not store warm items in the freezer.
• Before being used, the freezer must have reached
the set point temperature.
• Make sure that the door closes correctly and that
the door gasket seals correctly against the
container.
• For optimum performance it is recommended to
switch off, defrost and restart the unit at least
once a year. In case of heavy duty i.e. frequent
daily door openings, repeat this procedure
several times a year.

• On the occurrence of an alarm situation attempts
must be made to find out the reason for the
alarm and remove it as quickly as possible. If that
is not successful the necessary measures must
immediately be taken so that the stored goods do
not sustain any damage.
• At a temperature alarm the red LED alarm lights
up and an acoustic signal sounds. In addition the
corresponding alarm message appears on the
display.
• In the case of a powerfail alarm the green power
LED and the red LED alarm flash and an acoustic
signal sounds. The display is switched off but be
temporarly switched on again by pressing any
key.
After a given time (setting: EXTRA - DISPLAY -
BACKL. TIMEOUT ) the display switches off again.
The acoustic alarm can be suppressed for a set
time by pressing the ENTER button. During a
powerfail phase no parameters can be changed.
• If the internal temperature rises above the upper
limit during a powerfail phase a temperature
alarm is triggered and entered into the History
list. In the case of a door alarm the red LED lights
up and an acoustic signal sounds. In addition the
corresponding alarm message appears on the
display.
