3. ADVICE TO ENSURE EFFICIENT APPLIANCE
3.1 Shut-down procedures
In the event of emergency, shut down the
appliance by switching off power at the
main panel, by means of the knife switch or
by removing the plug from the power
socket.
3.2 Operating tips
Before starting up the appliance, clean the
inside of the cell thoroughly.
3.3 Pre-cooling
Before using the appliance for the first
time, or after a prolonged period of disuse,
pre-cool the cell by running an empty
cycle until the set operating temperature
has been reached. To ensure optimal
performance without any alteration to food
quality: arrange food products in such a
way as to favour the circulation of cold air
throughout the cell; open the door as little
as possible.
3.4 Loading the appliance
a) Ensure that foods to be chilled and/or
frozen are separate and do not have a
thickness greater than 50-80 mm. Do not
load the appliance beyond the quantity by
the manufacturer.
b) Ensure that there is sufficient clearance
between trays to enable free air circulation.
If the appliance is not completely full,
distribute the trays and foods evenly
throughout the available space.
c) Position trays inside the tray
compartment
as far as they will go, as close as
possible to the evaporator.
d) Position the core probe at the centre of
the largest product or food item; make
sure that the tip of the probe does not
protrude or touch the tray.
The probe must be cleaned and sanitised
before each new cycle (operation)
to prevent inadvertent contamination.
e) Avoid covering the trays and/or
containers
with insulating covers or film. The
more the product is insulated, the more
time is required for chilling or freezing.
Trays must be packaged when the product
has been chilled, before being
placed in storage.
