contact with any electrical component either inside or outside the ice-box. If the sensing tube needs to be bent within the confines of the refrigerator or freezer box, it must be done with great care, heeding the warnings above.

C: Operation:

The thermostat knob is marked from 1 to 7. The coldest setting is 7, & from this position the knob can be rotated counter-clockwise to setting 1, which is the warmest. If the knob is rotated further counter-clockwise, beyond setting 1, some initial resistance is felt & then the thermostat will click into the OFF position. On initial system start-up, it is recommended that you set the thermostat to number 4 & let the system run through a few cycles while monitoring box temperature before any adjustments are made.

Temperatures above are in Fahrenheit and are a range from warmest to coldest. The “in” temperature is when the unit will turn on during that setting. The “out” is the temperature when the unit will turn off during that setting. The temperature is measured by the silver capillary sensing tube on the thermostat. Each thermostat is stamped with the model number indicating the thermostat range. See below:
