2. The COOLING TEMPERATURE regulating valve is used to adjust the
temperature at which the refrigerant evaporates, which determines cooling
efficiency. The ideal temperature for operation is about 5-10 degrees Celsius
below the desired bath temperature. Refer to label below gauge for
approximate psi and evaporative temperature settings. The table from the
label is reproduced below.

Back Panel

The back panel has six standard features and two optional features. (See Figure
4.) The standard features are: 1) the probe connector, 2) the stirrer power outlet,
3) the system and heater fuses, 4) the power cord, 5) the drain valve, and 6) the
serial number notation. The two optional features are: 7) the RS-232 interface
connector and 8) the IEEE-488 interface connector.
1. The probe connector in the back panel is used for the temperature controller
probe.
2. The stirrer power is provided for the stirring motor.
3. The system and heater fuses are internal.
4. The power cord
5. A drain valve is provided for ease of removing the fluid media from the bath.
