Important installer and user information: A redundant temperature
sensing device has been included in this ULT freezer. This device is a type
“T” thermocouple. For convenient access, the thermocouple (Figure 1-3)
terminates in an interconnect jack (Figure 1-5) behind the base front cover.
(May be located differently in chests. See Section 1.) It is strongly
recommended that this thermocouple be attached to a redundant 24 hour
7 day monitoring system with alarm capabilities. Connecting the sensor to
a monitoring and alarm system separate from the freezer provides the
utmost in product safety, should the integral system fail. s

To remove the freezer from the pallet, use the 7/16" wrench to remove all
the bolts securing the shipping bracket to the pallet.
Remove the shipping bracket. Remove the ramp boards from the pallet
and place the slotted end over the ramp brackets on the pallet. The
support blocks on the ramps will be facing down. Before moving the
freezer, make sure the casters are unlocked and moving freely. Align the
caster with the ramp boards. Use adequate personnel to roll the freezer off
the pallet.
The freezer can be easily pushed to the desired approved location,
described following. If necessary, the doors and lower front panel may be
opened to move the unit through tight openings. When the freezer is in
position, set the front caster brakes.
Caution The freezer must not be moved with the product load inside. s
Caution For proper ventilation and airflow, a minimum clearance of 5” at
the rear and top and a clearance of 8” on the side of the freezer is required.
Allow adequate space in the front of the freezer for door opening. s
Locate the freezer on a firm, level surface in an area with an ambient
temperature between 18°C and 32°C. Provide ample room to reach the
