Precautions on Safe Operation
Precaution:
♦For your safety and to operate the instrument properly, please read this operation instruction
carefully before using and operate the following requirements in this manual.Where you violate
the instruction of manufacturer in this manual, it is possible to damage the protection of this
instrument.
♦This instrument shall not be used for purposes other than sterilization，drying，and it shall also
not be used for sterilizing the flammable, explosive and readily oxidizable products or strong acid,
alkali and saline solutions to avoid explosionand corruption of sterilizer chamber or pipelines.
♦The power supply of sterilizer should be properly connected according to nameplate on the
instrument. In case of excessive voltage fluctuation, the regulated power supply shall be used to
ensure optimum performance of the instrument. IF you are using other types of voltage, a
transformer must be used to prevent the instrument from being damaged.
♦It is necessary to ground the instrument properly, and never connect the ground wire to
plastic pipeline, gas pipe, telephone ground wire and lightning rod.
♦Never block the steam exhaust hole on the safety valve with articles, so that the safety valve
may work properly under abnormal conditions.
♦Always ensure that the reading of pressure gauge is "OMpa" before opening the chamber
cover. Never attempt to open the chamber cover and drainage valve, or draw out the steam
trapping bottle when the pressure inside the sterilizer chamber is over "OMpa" to avoid injury
from ejected pressurized steam.
♦Avoid dripping water to the control circuit when adding distilled water to the sterilizer
chamber to against electric shock or other faults.
♦When using waste processing bags or other type of bags, please put the bags into the
stainless steel basket before put into the sterilizer chamber to avoid affecting the precision of
temperature.
♦If the handle is turned by mistake during sterilization, it will not continue turning as it has
been locked by the interlocking device, and there will be a little steam exhausted to release. In this
case, press the"STOP" button to stop the instrument immediately. When opening the chamber
cover, turn the handle slightly toward the opposition direction that it is wrongly operated, and
then turn the handle counter-clockwise until the cover is released.
♦Observe the temperature variation inside the sterilizer chamber. The temperature is relatively
high when operation has been finished, keep the face and hands away from the sterilizer chamber
when opening the cover to avoid injury from ejected pressurized steam. Gloves must be used
when taking articles out of the sterilizer chamber.
♦Liquid does take some time to get cooling, verify whether the temperature is low enough or
not, when taking the liquid after sterilization out of the chamber to avoid scalding.

Drawell Scientific
♦Use only distilled water as sterilizing water to avoid affecting the service life of sterilizer.
♦When using the instrument continuously, 15 minutes and above interval is required before
next operation to allow the instrument to cool down, so that it will be able to produce adequate
saturated steam.
♦In case of abnormal conditions, such as noise, odor and smog, please turn off the power
immediately, and observe until the abnormal condition stops, and then contact the local dealer or
customer service department of our company.
♦The user shall observe the local regulations related to the pressurized vessels.

Drawell Scientific
3. Adding water
Adding distilled water into the sterilizer chamber until the water flows into the observation hole in
the middle of the water plate.
2) Push the handle rigntward slightly to move the cover to one side
★Note:
〇The indicator "locked" is off at this time, and the sterilizer will not be able to work until the chambercover
is closed and secured.
〇Do not open the chamber cover too fiercely, so that it will not be extruded and broken.
4.Loading articles to be sterilized
1) Put the articles to be sterilized into the baskets and close the cover
2) Make sure the water plate is placed well, in case baskets place on the heater directly.
3) Put the baskets lightly into the chamber
★Note:
〇Verify whether the water plate is in place or not before putting the baskets back into the sterilizer chamber, so that
they will not be put on the heater directly.
〇When plastic bag is used for sterilizing, please put some water into the bag and keep the bag open, and make sure

Drawell Scientific
the bags do not contact with the inner wall of the sterilizer. Sealed bags will result in inefficient sterilization. If the
sterilization chamber is over crowded, steam can not reach every corner, will result in incomplete sterilization.
〇When sterilizing the glassware like beaker, conical flask and test tube, the vessel must be put up side down or across.
If the vessel can only be in vertical direction, put a little water in the vessel before sterilizing.
〇When sterilizing the liquids like chemical reagent or menstruum, care must be taken to the volume of liquid inside the
container (3/4 of total volume of flask, and 1/2 of total volume of test tube), so that the liquid will not overflow from the
container during sterilizing.
〇The cover of container to be sterilized should be loosened for air exhaust to prevent container broken.
〇When melting the agar, each container should be less than 2 L, otherwise the melting may not be completed
thoroughly.
〇The DURHAM TEST TUBE with over 6mm caliber should be used, otherwise air bubble may stay in the tube.
〇Please put article temperature sensor properly if the instrument is attached artilcle thermometer.
5.Closing the sterilizer chamber cover
1) Push the handle leftward slightly until the arm leans against the arm stopped.
2) Turn the handle until it is secured and the cover closed indicator “Locked”is on. The cover closed indicator may
change repeatedly in course of tightening. When it is nearly secured, turn the handle slowly while observing
whether the cover closed indicator is on or not.
6. Selecting sterilizing program
Select the sterilization mode, set up the Sterilization time and drying time according to your needs.
★Note:
〇For sterilization of liquids, set a sterilization time longer than desired, taking a delaytime
into account:For example, if the volume of water in the flask is 3L , when the internal
temperature of the sterilizer chamber reaches the set value, another 33 minutes shall be
required for the water in the flask to reach this temperature, therefore, the sterilizing time
must be set to 53 minutes.
