Horizontal Cylindrical Pressure Steam Sterilizer
(Autoclave Machine)
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 clinics, scientific research institutes and other organizations to
sterilize surgical instruments, fabric glassed, culture media etc.

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.
Operation
Operation procedures:
manual operation
connection water----- trun on the water source
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.
By reaching the rating pressure, the sterilizing lamp will be on, and the timer would s
tart to count down. After counting to the zero, the buzzer would go off to remind the
end of the sterilizing. The unit would automatically exhaust the air, and pay attention
that don’t open the door till the needle of the pressure gauge point to zero. Open the d
oor a little for about 5~10 cm, and the objects can be fetched in 20~30 mins.( the po
wer could be shut off when the door is open)

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.
