If you attempt to open the lid when pressurized high pressure steam could
cause serious bodily injury. Do not stand close to the lid since steam will
exhaust once opened.
Do not open drain when vessel is pressurized. Since sterilization water is hot just after
sterilization, let the water cool before draining.
The bottle, located in the inside of the front door contains hot water after operation. Let the
water cool prior to removing the bottle. To avoid possible bodily injury, do not open the door
during operation.
The plate, lid and surrounding areas are hot after operation. To avoid bodily injury, do not touch
these areas. Always wear protective gear when removing a processed load.
Once the lid is open and all steam has exhausted remove sterilized material with heat-resistant
gloves to prevent bodily injury.
Hot steam will disperse out of the louvers located in the back of this unit if a malfunction
occurs. Do not close the louvers.
When using the pressure relief switch be sure not to touch the exhaust areas of the sterilizer
since high pressure steam will exhaust.
Do not operate this unit without a basket.

Operational Example
How to operate the “STERILIZE” process
Sterilize operation using a waste bag.
① Be sure to open the mouth of the bag to let steam.
② Keep the bag approximately 2/3” height of the total depth of the chamber (Example: SE310 is
17.5” deep, so the bag should be placed 11.5” from the bottom). If the bag is placed higher than
this point, steam will not disperse easily and may result in incomplete sterilization, in addition,
the bag can easily cover the exhaust in the upper part of the container.
③ Set the temperature lower than the heat resisting point of the bag.
④ Set time depends on quality and quantity of the material being sterilized. (See chart below)

Troubleshooting Guide
Safety
Self-diagnostic Circuitry
The Yamato sterilizer was designed with self-diagnostic circuitry capable of monitoring operation of
the sterilizer. If a malfunction occurs, the display panel blinks the error code and an alarm is sounded.
The microprocessor disables power to the heater element. If this occurs, check the error code and
immediately shut off the main breaker.
The safety valve is activated if pressure inside the chamber is abnormal. No special alarm is given
when the safety valve is activated. However, a significant amount of steam will spout out of the louvers
or spaces on the exterior. In this situation, there can be some problems such as an air purge or
problems with the temperature controller. Push the “ENTER” key immediately to stop the operation.
Turn off the main breaker after the steam spouting out settles down.

In case of power failure
If the main circuit breaker is turned off during operation or main power is temporally interrupted
during operation.
1.The sterilzier will remain in the state it was disabled at. A power failure will result in the
chamber remaining pressurized if it was under pressure at the time of the failure.
2.When power is restored the operation program is lost and the solenoid exhaust valve will
remain closed until the chamber temperature is below boiling point.
Do not open the lid in this situation or hot and high pressure steam will spout out.
If you want to open the lid, use the pressure relief switch to reduce pressure inside the chamber
to “0psi”.

it to cool. Wipe off any dirt on the exterior with a damp cloth. Do not use benzene, thinner or
cleanser to wipe, nor scrub with a brush.
Daily Maintenance
Cleaning after liquid loads
Biological media tends to boil at a higher rate compared to other liquids. This can cause media
to be splattered inside the chamber. Therefore, the chamber must be cleaned daily with a damp
cloth after temperature has cooled.
Weekly Maintenance
Cleaning the inside of the chamber
Clean the inside of the chamber with a clean damp cloth. Do not pull the filter out, located in the
bottom center when cleaning the inside of the chamber. If cleaned without the filter inside, the
pipe can get clogged with dust.
Filter cleaning
If the filter in the bottom center of the chamber is
clogged, drainage is prevented. Clean the filter in
appropriate intervals, according to frequency of
use.
Pull the filter out, from the bottom drain port. The
filter may be cleaned under the water faucet.
Cleaning the Door Gasket
The door gasket, located under the lid of the sterilizer can be wiped clean with a clean damp
cloth. The gasket should be examined for cracks or damage that can result in a poor pressure
seal. If replacement is needed, contact Yamato Scientific.
Cleaning the Pipe Heater
The pipe heater should be cleaned twice a month.
Accumulation of scale build up results in poor heat transfer and high sheath temperatures.
