Page 2: Chapter 1: Safety Measures
Chapter 1: Safety Measures I. Use Instruction Precautions: 1. Keep the instrument used in a clean work environment; 2. Only be used and maintained by skilled operators; 3. Do not remove any safety device; 4. If the loss is caused by incorrect use or failure to use the instructions, our company will not be responsible for it. - Page 3 IV. Work area The so-called working area refers to the area in front of the instrument operating panel. The work area must be determined by the operator who installs the peripheral equipment. It is the user's responsibility to ensure that the device is in a clean and safe working area during temperature control.
- Page 4 1） Usually refers to water Flash point ≥ 65 °C, which means that it must be used under 2） strict supervision; 3） The over-temperature protection device can be composed of a thermal oil sensor and a corresponding over-temperature protection switch; 4）...
- Page 5 VII. Environmental conditions 1. Indoor use only. 2. Use location: altitude is <2000 meters. 3. The maximum air humidity must not exceed 80% at 32℃. 4. Voltage is maintained at ±10% of rated value. 5. Cleaning level is 2. 6. Overvoltage level is 2 VIII.
- Page 6 (5) Unsuitable heat transfer media will negatively affect the instrumentation and cause damage to the device. Therefore, only use the manufacturer's specified thermal media and use within the specified pressure range. The temperature can only be controlled below the boiling point of the heat conduction medium, and the viscosity must not exceed 50 m2s when the heat conduction medium is operated at a low temperature.

5 If the instrument is located on the BMX, the brake device must be installed on the BMX; 6 Put some materials that can absorb heat conduction medium under the instrument to prevent overflow or leakage of heat conduction medium; 7 If any heat conduction medium overflows, it must be cleaned;... - Page 8 is caused by the incorrect voltage connection, our company is not responsible for any liability! Safety instructions: Danger: Please connect the instrument to ground! Warning: Do not move while the instrument is running The phase sequence and open circuit protectors are installed inside the three-phase electrical equipment.
- Page 9 Ensure that there is enough flowing air on the ventilation side of the circulation pump and compressor, and allow the discharged heat to dissipate in time. Check the tightness of the connecting pipe connection between the peripheral system and the temperature control system.
- Page 10 match with the range of heat conduction oil and temperature. In order to ensure the correct operation of the machine, it must be ensured that no air bubbles are in the system, the outlet is connected to the inlet of the reactor, and the inlet is connected to the outlet of the reactor.
- Page 11 be replaced regularly to ensure safe use). (3). To connect with new-fashioned glass reactor: using stainless steel bellows connection, and the connector adopts detachable connection. (4). The device connector is a consumable item and is not covered by the warranty scope of the whole machine. 2.

After the whole circulation system has been filled with the heat conduction medium (including the reactor), the liquid level in the expansion tank is at the adding level (the circulation system has basically eliminated air).
- Page 13 be modified. When an over-temperature condition occurs, the system will automatically cut off the operation. This function does not work when filling the conduction media. Warning: Be sure to use the manufacturer's recommended oil. VII. Liquid level indication The instrument uses mechanical liquid level indication to minimize the failure of the liquid level display fault.

The indicator lights up when the controller is powered on; at the first second, the digital tube display “dF03” and the lower row of the digital tube display the sensor input type: two seconds after“IN–P”, the upper row of the digital tube displays the upper range value and the lower row of the digital tube display the next range value.
- Page 17 button, the controller automatically saves the set parameters and exits the temperature setting state. In the temperature setting state, if there is no buttons to be pressed within 60 seconds, the controller will automatically return to the normal state and the parameters will not be saved. In the non-setting state, click the “decrease/view”...

- Page 19 XIV. System Self-adjustment When the temperature control effect is not ideal, the user can perform system self-adjustment. In the process of self-adjustment, there will be a large overshoot of temperature, and users should fully consider this factor before performing system self-adjustment. In the non-setting state, press and hold the “...
