Intended use

Vestfrost biomedical freezers are designed to provide reliable temperature stability and precision
and ensure an ideal cold temperature storage for sensitive items is achieved. The products are
designed for the following operating ranges:
WARNING: This unit is not a "rapid-freeze" device. Freezing large quantities of liquid,
or high-water content items, will temporarily increase the chamber temperature and will cause
the compressors to operate for a prolonged time period. Avoid opening the door for extended
time periods since chamber temperature air will escape rapidly. Also, keep the inner doors closed
as much as possible. When room air, which is higher in humidity, replaces chamber air, frost may
develop in the chamber more rapidly.
