Standards
National Pharmacopoeia, Australian AS3100, US FDA, EN, ICH, cGMP/ICH/380/95/Q1A/Q1B, German DIN 12880 Class 3.1, European Union CE safety certification
Steps
1. Connect the power supply and ensure that the voltage is single-phase AC220V/50Hz.
2. Open the device and select the Chinese or English interface through the LCD display.
3. Set the required temperature (0~ 65 ° C) and humidity (40~ 95% R. H), and use the user password to control.
4. Adjust the wind speed and running time as required (0 to 99 hours or 0 to 9999 minutes).
5. Place the sample on the movable mesh Shelf and close the double door.
6. Start the device, monitor the running status, and connect multiple devices through the RS485 interface for real-time monitoring.
7. After the experiment, stop running and clean the liner and shelf.
Notice
• Ambient Temperature should be kept at 10~ 30 ℃ and humidity below 70%.
• Regularly check the over-temperature protection device to ensure that the safety function is normal.
• Use appropriate tools when cleaning to avoid damage to liners and accessories.
• Disconnect the power supply during maintenance, and the electrical components are located at the back of the box.
• Use original imported refrigerant to avoid environment pollution.
• Read the user manual before operation and follow the set parameters.
