Using this gas sterilizer is easy. First, connect the power supply cable to a suitable power source. Make sure all the connections - power supply, abator, and exhaust outlet - are properly attached. Insert the key to start the sterilization process. When using, keep in mind that due to lack of previous testing, closely monitor its performance. For maintenance, regularly check the exterior for any new scratches or damages. Clean the surfaces gently with a soft cloth. If you notice any issues during use, stop the machine immediately and consult a professional.
