Safety Considerations
In this manual, the following symbols and conventions are
used:
This symbol used alone indicates important
operating instructions which reduce the risk of
injury or poor performance of the unit.
CAUTION: This symbol, in the context of a
CAUTION, indicates a potentially hazardous
situation which if not avoided could result in
minor to moderate injury or damage to the
equipment.
WARNING: This symbol indicates potentially
hazardous situations which, if not avoided, could
result in serious injury or death.
WARNING: This symbol indicates situations
where dangerous voltages exist and potential for
electrical shock is present.
The snowflake symbol indicates extreme low
temperatures and high risk of frostbite. Do not
touch bare metal or samples with unprotected
body parts.
Below are important safety precautions that apply to this
product:
Use this product only in the way described in the
product literature and in this manual. Before using
it, verify that this product is suitable for its
intended use. If this equipment is used in a
manner not specified by the manufacturer, the
protection provided by the equipment may be
impaired.
Do not modify system components, especially
the controller. Use OEM exact replacement
equipment or parts. Before use, confirm that the
product has not been altered in any way.
WARNING: Your unit must be properly grounded
in conformity with national and local electrical
codes. Never connect the unit to overloaded
power sources.
WARNING: Disconnect the unit from all power
sources before cleaning, troubleshooting, or
performing other maintenance on the product or
its controls.
This symbol indicates a need to use gloves during
the indicated procedures. If performing
decontamination procedures, use chemically
resistant gloves. Use insulated gloves for handling
samples and when using liquid nitrogen.
Before installing, using or maintaining this
product, please be sure to read this manual and
product warning labels carefully. Failure to follow
these instructions may cause this product to
malfunction, which could result in injury or
damage.
WARNING: “Caution, risk of fire”. This unit is
charged with hydrocarbon refrigerants.
At delivery, examine the exterior for physical damage while
the carrier’s representative is present. If exterior damage is
present, carefully unpack and inspect the unit and all
accessories for damage.
If there is no exterior damage, unpack and inspect the
equipment within five days of delivery. If you find any damage,
keep the packing materials and immediately report the
damage to the carrier. Do not return goods to the
manufacturer without written authorization. When submitting
a claim for shipping damage, request that the carrier inspect
the shipping container and equipment.
The packaging can be stored and re-used.
Packing List

•English and metric connectors
If specified on the order, the bag may also include:
IMPORTANT NOTE: Thermo Fisher Scientific
recommends 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.
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.
WARNING: This unit is not a “rapid-freeze”
device. Freezing large quantities of liquid, or highwater content items, will temporarily increase the
chamber temperature and will cause the
compressors to operate for a prolonged time
period.
Battery Door Opening /
Closing
To open the grille door, pull the door from the top right corner
as shown in the figure below.
To close the grille door, push the door against frame to hold
latch in position.
Figure 1. Door Opening
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.
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.
CAUTION: Failure to follow these procedures or
overloading the unit may cause undue stress on
the compressors or jeopardize user product
safety.
