circulation of cold air in the entire cell;
• avoid prolonged and frequent door openings.

How to load the machine
A) In order to grant chilling/freezing time ensure that food
to be chilled/frozen in separated pieces (max thickness
2”/50mm).
B) Ensure a sufficient distance is maintained between the
trays to allow adequate air circulation.
If the machine is not completely loaded, distribute the
trays and the load over the entire useful height avoiding
concentrations.
C) Place the trays in the inner part of the door, making sure
that they are as close as possible to the evaporator.
D) The core probe must be positioned correctly in the
center of the product with the largest cut or piece, making
sure that the tip of the probe does not protrude out or
touch the tray. The probe must be cleaned and sanitized
before each new cycle (work) in order to avoid undesirable
contamination.
E) Do not cover the trays and/or container with lids or
insulating films: the more the food is insulated the greater
the time required for chilling and rapid freezing.
Packaging of the trays must be performed when the
product is already frozen, before it is put into storage.
