Packing List
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 thermocou-
ple be attached to a redundant 24 hour 7 day monitoring system with
alarm capabilities. Connecting the sensor to a monitoring and alarm sys-
tem separate from the freezer provides the utmost in product safety,
should the integral system fail.
