• If the cooling light is not lit, check the control temperature set point and bath temperature to verify
that cooling is required.
• Check for low or high line voltage.
• Check for blocked airflow through ventilation screens.
• Check ambient air temperature. Refrigeration unit should not be operated above 32°C ambient
temperature as high air temperature may cause the refrigeration compressor to temporarily shut
down.
• Check for excessive heat being transferred to the bath liquid as this may exceed the cooling
capacity of the refrigeration system.

The first time the Controller is powered up, a language selection menu is displayed which allows the
user to select the language used for operational displays and programming. This is a one-time
display; the next time the Controller is powered up, either Standby or the main operational display
will appear once the initial self-test procedure has been completed.
You may change the language used for operational and programming displays in either of two ways.
One is to change the language using the Preferences sub-menu (see Section 4.11 – Setting
Operational Parameters and Functions). The other is to recall the initial power-up language selection
display. This is performed as follows.
1. Press the Power Button to turn Controller power off (Standby displayed).
2. Place the circuit breaker/power switch on the rear panel in the OFF position (display blank).
3. Press and hold ESC Button.
4. Place the circuit breaker/power switch in the ON position; continue holding ESC Button.
5. Release the ESC Button when the language selection menu is displayed.
6. Rotate the Select/Set Knob until the desired language is highlighted.
7. Press the Select/Set Knob.
The Controller will complete the start-up sequence and display “Standby” on the LCD. All operating
and programming screens will now be displayed in the selected language.
