b. Installing the Temperature Probe
10. Locate the 0.500” pre-punched hole in the upper left hand
back corner of the chamber ceiling. Remove the tie wrap
securing the coiled probe/solenoid harness. Uncoil the
probe lead and run the probe tip (approximately 12”)
down through
0.500” porthole
(Figure 6-4).

14. Plug the solenoid/probe connector into the BUS connec-
tion and secure with a screw on the right and left side.
The connector is keyed.
15. Loosen the terminal screws on the solenoid. Slide the
spade lug connectors under the screws and tighten to
secure.

switch at the OFF position. Turn the freezer on. The
Inject light on the BUS control panel will illuminate but
