2*Cooling Lock Function
In general condition, the cooling of chamber will be faster than that of sterilized articles, and in
other words, the actual temp of load may be higher than the value on meter (especially for liquid).
Where the cover of chamber is opened before sterilized articles reaching safe condition, the
operator may face scald dangers. For safety purpose, this series sterilizer is designed with cooling
lock function so that the user may set cooling lock OPEN temp to have the cover only be opened
when temp in chamber is lower than set OPEN temp. In case the load thermometer is equipped,
the cover could only be opened when the temp in chamber and load temp are both lower than
the set OPEN temp.
CHAPTER 2 INSTALLATION OF INSTRUMENT
I. PLACEMENT OF INSTRUMENT
* This is a precision instrument, and it must be placed on the level ground with the brakes
of four wheels pressed down during installation. Never place the instrument in an environment
with high humidity and direct sunlight or a room with temperature lower than 5* or over 40 *.
* For better heat dispersion, it is recommended to keep some
gaps between the instrument and the wall, normally at leastAt least15cm
15cm from the back , 15cm from the left and 30cm from the
right.
* During steam exhaust or when opening the chamber cover,
At
leastsome steam may spill over, therefore, it is recommended not
30cmto
install the instrument beneath the fire alarm sensor to avoid
triggering the alarm.
* The steam exhaust hole of the safety valve must be kept
away from the power socket and not blocked.
At least
15cm
PLACEMENT OF INSTRUMENT
3*Optional accessories:
1*Load thermometer:
* There are some articles (such as liquid) with higher thermal inertia, so when the temp of
chamber reaches sterilization temp, the temp of load is not high enough for sterilization. For the
purpose of better sterilization effect, it is recommended to monitor the real temp of load with load
thermometer. In this case, the temp of sterilization chamber will firstly reach sterilization temp,
but the sterilization timer will only start when the load really comes to the set sterilization temp.
* Note:
After the installation of load thermometer, set it in administrator menu to be enabled. (see details
in Chapter IV: Setting of Administrator).
After use, the load thermometer should be placed on water level plate and kept in sound. The
load thermometer should be set to disabled in administrator menu for long term idling.
2)Printer:
* The printer is optional for the need of recording sterilization process parameters. For enabling
the printer, the operator shall enter into administrator menu to set printer to enabled and choose
language of printing (English or Chinese) and display of date (DDMMYY or YYMMDD).

LOCKED indicator will be off and sterilizer
will be disabled.
* Grab the handle and open the cover of chamber
* Note:
Do not open the chamber cover rudely to prevent seal ring from damage.
During Lock lever operation, it is necessary to make sure that the instrument
has been powered on and power switch is also on.
3. ADDING WATER
* Check and confirm if the drainage valve is turned off, otherwise the water
in sterilization chamber or water tank may be discharged.
* The distilled water must be used inside the sterilizer chamber, well water,
brine or hard water must be avoided to prevent the sterilizer chamber from
corrosion, fouling and shortening the life of heater.
* In order to ensure the conductivity of filled water, do not use ultrapure water.
1) DA Series
* Add distilled water into the sterilizer chamber until the water flows into the
observation hole in the middle of the water level plate. The water level shall
not exceed the water plate.
1. TURNING ON THE POWER
* Turn on the power switch on the left side
of the machine
* The system may start self-inspection
automatically, and then enter the standby

* No need to pre-add water to the DA series water tank, bu the cooling water in
the water tank may increase continuously when the instrument works continuously.
when the water level is higher than the note "HIGH" , drain the water in the water
tank.
* The water level inside the sterilizer chamber may decrease after each sterilizing.
Care must be taken to compensate distilled water on time.
* If it is in a constant water shortage status, the heater may always be easy to
dry scorch and then get rusted.
2) DF Series / DR Series
* Check if WATER indicator on display panel is on, when WATER indicator is off,
the system will automatically start to feed water. When the water is short in tank,
the instrument will show E11 and alarm.
* Check if the water level tube at rear right of instrument stays between LOW and
HIGH.When the level is below LOW line, fully drain water in water tank and
sterilization chamber, and add water until HIGH line.
* The water feed ladle with guide port will be used to add water to water tank and
do not have water overflowed. In case of overflowing, dry it with cloth at once.
4.LOADING ARTICLES TO BE STERILIZED
Chamber
1*Take the stainless steel basket out, and put the
temp
articles to be sterilized into the basket;sensor
2*Put the basket back to the chamber of sterilizer
*Note:
ExhaustDo not block outlet or extrude the sensor in
port
sterilization chamber, otherwise it may lead to
abnormal work of instrument.Verify whether the
water level plate is in place or not before putting the basket back into the sterilizer
chamber, so that it will not be put on the heater directly.The load thermometer
should be placed on water level plate and kept in sound.
* When plastic bag is used for sterilizing, please place the bag into the basket
beforehand to avoid affecting the accuracy of temperature control of sterilizer.
* When sterilizing the waste processing bag, the bag must be opened to allow
the steam to contact the articles to be sterilized adequately.
* When sterilizing the glassware like beaker, conical flask and test tube, the
vessel must be put upside down or across. If the vessel can only be in vertical
direction, put little water to the vessel before sterilizing.
* 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.
* The cover of container to be sterilized should be loosened for air exhaust to
prevent container broken.
* During agar melting, the volume of container should be lower than 2L to
prevent incomplete melting.
* The DURHAM TEST TUBE with over 6mm caliber should be used, otherwise
air bubble may stay in the tube.
Cover of water tank
5. CLOSING THE STERILIZER CHAMBER COVER
Add water to water tank
* The water level sensor should be regularly maintained, and it is recommended
to frequently replace the water in sterilization chamber and water tank to prevent
scale in water attaching to water level sensor and therefore affecting normal work
of water level sensor.
* Slightly press the middle of front end of chamber cover, slide the lock lever
to the left to LOCK position so the system will trigger a warning tune and then
the LOCKED indicator on display panel will be on.
* Note:
* Before closing the cover, check if there are objects on the surface of sealing
ring of the cover and its contact part to avoid damaging the sealing ring that may
result in steam leakage.
* The sterilizer will only start working until the LOCKED indicator is light;
otherwise, the sterilizer will not be functional.

2. DELETING THE PROGRAM
* Select the program to be deleted, and press and hold the *FUNC* &
*STOP* button at the same time to delete the current program.
* These six basic programs ,U01-U06,cannot be modified or deleted.
III. CLOCK CHECKING AND CALIBRATION
* Under standby status, press *FUNC* and *NEXT* buttons together to
enter the clock checking and calibration mode F05, with the digital display A and
B showing the currently parameters automatically by sequence:
Screen 1
Screen 2
Screen 3
3. SETTING THE STERILIZING TIME
* Some articles (such as liquid) have higher thermal inertia, so for obtaining
better sterilization effect, it is recommended to use load thermometer. In case
of not providing load thermometer, it is necessary to compensate it based on
normal sterilization time.
It is required to delay the sterilizing time of liquid, i.e. the set sterilizing time shall
be delayed:
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.
Actual required sterilizing time (53min) = Delay time (33min) + Normal sterilizing
time (20min)

* Where load thermometer is provided and enabled, the temp of sterilization
chamber will reach set sterilization temp, but the timer of sterilization won't start
to count backward. The timer of sterilization could only start when the article
really comes to set sterilization temp.
* When waste processing bag is used for sterilizing, 300~500ml water will be
helpful to shorten the delay time of temperature-rise period.
* When sterilizing the plastic products, the sterilizing time shall be delayed
adequately due to the slow heat conduction of plastic products.
1) After setting the time, press *DATA* button to exit.
