Operating procedures (settings for Standalone overheat prevention device
(Thermostat))
As a safety measure for preventing overheat, a standalone overheat prevention device (Thermostat)
hydraulic overheat prevention device (manual return) is installed.
Temperature setting range and functions
The temperature setting range for the standalone overheat prevention device (Thermostat) is “50 ～
350 .”
When the temperature in the bath keeps rising beyond the controller set temperature and reaches the
set temperature of the standalone overheat prevention device (Thermostat), the heater circuit trips
and the controller operation is shut off.
When the standalone overheat prevention device (Thermostat) is activated, it will not be released until
the ELB is turned on.

if the device functions improperly.
② The temperature setting range for the standalone overheat prevention device is “50℃～
320℃.” Be sure to set the overheat prevention activation temperature correctly otherwise the
device may not start, the overheat prevention device is activated before temperature in the
bath increases completely, or a fire or other unexpected accidents may result.
The temperature is set at 320℃ on shipping from the factory.
③ The standalone overheat prevention device (Thermostat) has been designed to prevent
overheating of devices not to protect samples. The device does not prevent accidents
