Thermo Fisher Scientific ULT Freezers
Installation
Location
Install the unit in a level area free from vibration with a
minimum of 8" (20 cm) of space on the top and sides, 6" (15
cm) in back. Refer to
leveling cabinets. Allow enough clearance so that door can
swing open at least 85°.
The rear spacing posts provided with the freezer can be used
to ensure proper clearance. To install the spacing posts,
screw them into the back side of the unit, in the rear deck
area.
Do not position the equipment in direct sunlight or near
heating diffusers, radiators, or other sources of heat. The
ambient temperature range at the location must be 15°C to
32°C (59°F to 90°F).
Wiring
Leveling
Make sure that the floor is level. The unit must be level both
front to back and side to side.
The 300 and 400 box capacity models are equipped with one
or two leveling legs on the right hand side. Leveling legs on
300 size must be used as a safety precaution.
Ensure to lock the brakes for units equipped with casters.
Backup System (Optional)
If you are using a CO
2
or LN
2
backup system, refer to
for installation and operation
instructions.

WARNING:
Do not exceed the electrical rating
printed on the data plate located on the lower
left side of the unit.
CAUTION:
Connect the equipment to the
correct power source. Incorrect voltage can
result in severe damage to the equipment.
CAUTION:
For personal safety and trouble-free
operation, this unit must be properly grounded
before it is used. Failure to ground the equipment
may cause personal injury or damage to the
equipment. Always conform to the National
Electrical Code and local codes. Do not connect
the unit to overloaded power lines.
CAUTION:
Do not position the unit in a way that
impedes access to the disconnecting device or
circuit breaker in the back of the unit.
CAUTION:
Always connect the freezer to a
dedicated (separate) circuit. Each freezer is
equipped with a service cord and plug designed
to connect it to a power outlet which delivers the
correct voltage. Supply voltage must be within
±10% of the freezer rated voltage.
CAUTION:
Never remove or disable the
grounding prong from the service cord plug. If the
prong is removed, the warranty is invalidated.
CAUTION:
Never drill holes in or near the cabinet
walls. Drilling could damage the insulation and
make the unit inoperable.
