121 ℃ corresponds to 0.11MPa). The choice of temperature and time is generally 121 ℃ 20 minutes (min) or 132 ℃ 8 minutes (min), the user can decide according to the actual situation.
QiuLong Instruments counterpressure autoclave (carbon steel type) instructions for use
1 Add water:
Open the lid directly to the water, observe the water level, the water level should be in the heating tube above the plane of more than 3cm, but should not be too much, close the water inlet valve (temporarily do not shut down the bleeder valve)
2 Lid open/close:
Open the counterclockwise rotation of the handwheel Note: Do not exert too much force, subject to the seal does not leak.
3 Put the package: according to the instructions in this item 2 method to open the lid, the required items will be placed in the bucket as required. Note:Do not stack too tightly to prevent steam penetration. Seal the lid according to instruction 2 after placing.
4 Power:
After connecting the power supply according to the four methods of this instruction, close the external power switch and turn on the power of the equipment. Note: When using 220V power supply, the zero line should be 2.5 square millimeters above the copper core wire.
5 time setting:
According to the sterilized items of sterilization needs, toggle the time relay on the alphabet dial code, appear "M" and then toggle the digital dial code to determine the time value to "minutes" as a unit. Sterilization temperature setting: Toggle the dial code on the thermostat selected sterilization temperature, factory has been set to the general sterilization temperature of 121 ℃, according to the needs of different sterilized items can be set arbitrarily.
6 counter-pressure temperature: open the air compressor and counter-pressure inlet valve into the air pressure, the pressure value is determined by the required sterilization temperature (the pressure gauge is a double scale display, can correspond to see 0.1 MPA corresponds to 120 degrees), pressurized to the corresponding value and then close the inlet valve. After connecting the external power supply, turn on the power switch Ⅰ and Ⅱ on the control panel in turn, the power indicator will light up, and then turn on the 2 or 4KW heating switch, the equipment begins to heat.
Note:
(1) If there is a lack of water in the heating process, power failure alarm, you must first turn off the power supply, open the bleeder valve, exhaust the steam in the body, the pressure gauge pointer back to "0", and then open the water valve to fill the water, and then according to the above instructions to re-heat.
(2) If there is no actual shortage of water and power failure alarm, you can press the red reset switch on the control panel, but after sterilization must be in the off position.
(3) When the pressure exceeds 0.25Mpa and the safety valve is not open, the power must be turned off to find out the reason, troubleshooting before continuing to use.
7 sterilization: when the pressure in the sterilizer reaches the set pressure temperature sterilizer automatically transferred to the sterilization timer. Note: Timer automatic timing is controlled by the temperature control table AL1, to change the timing temperature point must press the temperature control table SET key for 5 seconds to enter the setup, when the display AL1 can be set when the timing temperature point.
8 counterpressure cooling:
After the buzzer prompts the end of sterilization, counterpressure cooling, this time the water pump, air compressor, air inlet valve, counterpressure into the water valve are open, observe the pressure gauge pointer swing, in the case of keeping the pressure basically unchanged, adjust the air inlet valve, counterpressure into the water valve flow rate, when the temperature of the inner chamber drops to below 80 ℃, close the air inlet valve, water valve, air compressor, Water pump, and then, open the sterilizer itself bleeder valve, the pressure gauge pointer back to "0", in accordance with the instructions of the 2 method will be open and lift the lid to remove the mouth of the device, the sterilization package out.
