General Recommendations
Temperature Monitoring
General Usage
This refrigeration system is designed to maintain ultra-low
temperatures with safety in an ambient environment within
15°C to 32°C (59°F to 90°F), only when the freezer is used for
storage. For TSX70086* models, the maximum operating
environment is 28°C (83°F).
Initial Loading
Allow the freezer to operate at the desired temperature for a
minimum of 12 hours before loading.
Load the freezer one shelf at a time, beginning with the top
shelf. After loading each shelf, allow the freezer to recover to
the desired set point before loading the next shelf. Repeat this
process until the freezer is fully loaded.
Battery Door
Opening / Closing
To open the grille door, pull the door from the top right corner
as shown in the following figure.
To close the grille door, push the door against frame to hold
latch in position.

IMPORTANT NOTE: We recommend the use
of a redundant and independent temperature
monitoring system so that the freezer can be
monitored continuously for performance
commensurate with the value of product
stored.
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.
CAUTION: Failure to follow these procedures
or overloading the unit may cause undue
stress on the compressors or jeopardize user
product safety.
