Specifications: Inner chamber volume: 24L（φ270×410 mm） Working pressure: 0.22Mpa Working temperature: 134℃ Adjustment of temperature: 105-134℃ Timer: 0-60 min Heat average: ≤ ± 1℃ Power: 1.5 KW / AC220V /110V 50Hz Plate size: 340 ×200 × 30 mm ( 3piece ) Dimension: 560 × 350 × 500 mm Package dimension: 620 × 410 × 570 mm G.W/N. W: 20/18 kg Safety protection device: 1. Water-off & over-temperature protection. When the heating element is heating without water, the power supply will be cut. 2. Over-current protection. If the current exceeds the rated value, the power broken circuit will cut power automatically. 3. Safety valve. When the pressure exceeds 0.22Mpa(34Psi), the sterilizer will automatically exhaust to drop the pressure Maintenance: l. To ensure the reliability of the steriliza*tion effect chemical indicating piece of biologic indicating piece must be put into the sterilization chamber, together with the: objects to be sterilized. After sterilizing, the sterilization effect can be checked. 2. Safety valve and the exhaust valve are on the top, Safety valve must be checked once every year If it is in malfunction, replace it. If the safety valve is in malfunction during use and the pressure keeps increasing, the power supply must be cut to ensure a safe use. 3. The rubber seal ring is easily aged. If aging causes leakage, the seal ring should be replaced in time. 4. The pressure meter must be standardization every year. 5. The machine must be keeping clean, and protecting the incrustant occurs on the surface, often method is wash it with distilling water once a week. 6. If the overheat protector be damaged, you just take of the round cover on the bottom, and change the protector.
