Precautions for Using Low-Temperature Thermostatic Baths

　　1. Add water or alcohol before use. Keep the level above the instrument's minimum-level mark to ensure proper performance.

　　2. Connect power, switch on and select the required temperature.

　　3. Switch on the circulation pump to equalize the water or alcohol temperature in the bath.

　　4. Once the set temperature is reached, place the object to be cooled in the bath or circulate coolant externally to establish a second controlled-temperature zone.

　　Refrigerated thermostatic bath precautions:

　　At low temperatures, the coolant also cools the pump. If the circulation pump is off, moisture can form inside its motor and cause slight electrical leakage. Keep the circulation pump running during use so that motor heat evaporates moisture. This issue does not arise when the pump and motor are installed separately.
