HORIZONTAL CYLINDRICAL PRESSURE STEAM STERILIZER
General
Saturated pressure steam is used to sterilize article, for it will liberate a great amount of heat when condensing. To make the articles (need to be sterilized) hot and wet for a certain time, most resistant bacterial spores will be killed, and then sterilization aim is reached. The method is reliable, economical, and easy to be controlled, so it has been used for more than one hundred years.
This unit is ideal equipment for hospitals, chemical, food, scientific research institutes and other organizations to sterilize surgical instruments, dressings, medicines, culture medium, food, fabric glassed etc.

Specifications
The main body is composed of a chamber and steam-jacket with closed double jacket. The chamber wall will be pre-heated as steam enters and fills the jacket up. A main valve is connected between the chamber and the jacket, which is turned to "sterilize" position and admit steam from jacket to chamber to make articles moist and heated. The above-mentioned method ensures requirements for pre-heating, sterilizing, drying and following operations.
The vaporizer, gauge in front above easy watch, the thermometer on the side, all the pilots and display in front lower part control box for easy operating. (fig.1)

Installation
for installation. More floor space around the sterilizer is set aside for operating and repairing. The Min. Installation size for single door 200×93×182cm, for double doors 200×93×182cm.(see fig.3)
Connect inlet with tap water supply and outlet with drain pipelines so as to make daily operation simpler.
Extend exhaust pipe outside to avoid vapor throughout inside, so as to affect operation inside.
During sterilizing, condense will be discharged through the condense ejector. It is suggested that a cone-shaped funnel is supplied to join the exhaust pipe and drain pipe. Thus the drainage of condense may be easily observed, as well as prevent drain flowing back, in case of drain line clogged.
The unit has been fully inspected before leaving the factory, but after installation by users, training should be performed according to manual instructions. In case that anything abnormal occurs, it should be resolved until the unit is in operation.

connection the power-----pilot display
Pile --------The articles (to sterilize) should be well packed and separated certain distance from each other in chamber, so as to leave free passage for steam. Dressing package cannot be close to chamber door, otherwise condense drops along door into dressing and prolongs drying time. In general dressing package should be no more than 20×20×10cm, otherwise the period of sterilizing time would be prolonged .If sterilize solution, pour it into a rigid heat-resistant flask, do not exceed 3/4 containment of the flask. Stuff mouth with cotton and gauze, and bind it with yarn. Be sure not to use a non-perforated rubber stopper or cork, or the flask will be broken. Put the flask onto a larger enamelware or metal tray, in case the explosion of the bottle occurs, the liquid won't flow away to pollute and damage the inside of the sterilizer.
Close the door, turn the safety handle clockwise to the center position, to make radial arms into the door ring, then turn the octagonal hand wheel clockwise along axis, till the door is steam-tight (Avoid over-tightening or it will shorten the life of the door gasket). Then the door close indicator lights. Solenoid valve is closed so that steam pipelines admit the steam into chamber. For the double-doors unit, till both the front and the back doors are all closed, then the door close indicator lights.
Preset Sterilizing Time:
The customer can preset the required sterilizing time (see form 1) according to following table. Turn the timer knob on the time line you wanted clockwise. When it reached the preset temperature, the pilot of time light, the timer start to count automatically.

setting fulfill---- press key SET. Pilot door,start, water-in on. Auto water-in to high level and the pilot off, and heating pilot on, this time you press start the buzzer sound to inform you setting temperature and time.
Press key start----- sterilizing begin.
End---- buzzer sound, when the inner gauge show zero, open the door the buzzer stop.
At the end of the sterilization period, in case of rapid decrease in pressure of chamber, solution or culture media in flasks would boil over or be spoiled. Therefore, turn the main valve knob to "slow exhaust" position to release the steam in the chamber slowly. Also cut off steam supply, let pressure and temperature in chamber drop naturally. Another way is provided to turn pressure adjustment switch to "close "position till chamber pressure gauge is reduced to "0". Wait a few minutes after main valve is turned to "slow exhaust", door can be opened.
End------If no more sterilization is needed, switch off the key emergency, to exhaust the steam in jacket and chamber, and open the door slightly to release steam from the chamber in order to keep its inner surface dry. And then cut off the power.

Notice
Do not sterilize different articles at the same time, such as dressing and solution or the same article but has different sterilization requirements
Check the water level indicator before using the unit, see whether it has sufficient water in tank, if not, add more water when the water level below water line, adding water must in no pressure state.
if alarm pilot for the water level on, it'll auto exhaust the steam, press emergency key or turn off the power then restart the power,the adding water going on, this time the pilot off, then press key start to going on the heating.
If you want adding water in the standby,press emergency key, the machine recover to the state of connect power, vaporize & magnet valve open to release, pilot start,heating and sterilize off, press repeat useless. Thus it auto adding the water and going on heating.
The handle of safety valve draw up 1-2times per week,make it smoothly.
Electric connector should tighten often to prevent loose and overheat.
Keep the sterilizer clean and dry, particularly if not used for a certain period of time, please clean up for the purpose of no rust. And lubricate the active parts regularly.
The unit should be operated in normal conditions, as well as periodically checked and maintained by professional personnel.
Operating regulations should be set up beside the unit, for the convenience of reference and conformance.
Protective earth should be provide to ensure safety.
In the course of sterilizing, if the safety gauge release,means the jacket pressure over the working pressure, you should inspect the pressure controller gauge and safety valve.
Maintenance
Gasket:
The door gasket of rubber should be replaced timely, if steam leakage occurs.
Pressure gauge:
If pressure gauge pointer doesn't return to "0" or reading isn't accurate, repairs should be made and then see if it up to standard pressure gauge. If not, replace it with new one.
Thermometer:
There are one thermometer, equipped in condenser outlet at the bottom of chamber, for test the temperature between condensate and chamber ,If temperature difference of them is large and the mercurial thermometer is in good order, the dial one should be repaired and checked.
Pressure controller:
It is equipped with temperature pressure controller preset: 0.05MPa,~0.15Mpa, after be using for a period and large difference please replace.
