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 integral system fail. s
