Chapter 3 – Operation
Introduction
The Front Panel Switches control power to the chamber. The Front Panel Lights provide
indication of heat and cool functions.
The Limit Controller is a protection device. It turns the chamber OFF if the workspace
temperature exceeds either a high temperature or low temperature limit set point.
The Temperature Controller controls the temperature of the chamber. It can function as either a
single set point controller or as a programmable profile controller. The Temperature Controller
automatically turns the refrigeration system on or off based on the demand for cooling.
Refer to the separate F4T or F4 Temperature Controller manual for details on how to use
the Temperature Controller.
!
CAUTION:
This chamber has a crankcase heater to protect the high-stage compressor. The
chamber must be connected to the power source AND the Main Disconnect
Switch must be ON for 3 hours prior to operating the chamber. Although it
may be safe to use the chamber immediately, this procedure ensures the
longest possible life for the high-stage compressor if the chamber has been
removed from the power source for more than 24 hours.
