The chamber is refrigerated by the forced circulation of cooled air inside the chamber. Ensure that the
air intake and exhaust vents are not blocked. Adequate space should be provided between the items
inside the unit to allow air circulation.
If any electrical equipment is used in the chamber, the chamber temperature cannot be maintained due to
the heat emission from the equipment. Refer to the table below when you use any equipment.
