Safety Information
Safety Precautions
Do not use this unit for any purpose other than its intended use, described in this manual.
This unit is not explosion proof. Never use in flammable or explosive gas environments.
Be sure to ground the unit. Electric leak could cause electrical shock or fire.
Be sure to use a power supply with more than the rated capacity specified in this manual. Use
of a power supply without the correct rated voltage and current could cause fire or electric
shock.
If smoke or any strange odor should disburse from this unit, turn the breaker off immediately
and pull out the main power cord. Then contact Yamato Scientific. Neglecting this procedure
can result in fire or electric shock. Never try repairing the unit yourself.
Forcibly bending, pulling, wrenching or extending the power cord can cause a fire or electric
shock.
Overheat or fire can occur if the power cord is bundled or if an object is on the cord.
The use of explosive, flammable or such compounds can cause explosion or fire. (See Pg.7)
Disassembling this unit can cause fire, electric shock or other crisis’s.
The exhaust is located on the right side of the unit. Possibility of personal injury if you come in
contact with this area during operation or for a period of time after use.

Safety Information
Safety Precautions
Do not plug the exhaust. Any obstruction in the exhaust may cause the tank to build pressure
and become hotter the normal.
Do not attempt to open the sterilizer lid until the pressure is at “0psi”.
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.

Safety Information
Safety Precautions
In the event of electrical storm turn off the main circuit breaker. Neglecting this procedure can
result in fire, electric shock or other troubles due to thunderbolts.
In the event of a power interruption or the main circuit breaker is switched off during operation
the sterilizer solenoid exhaust valve will remain closed once power has been restored. The
solenoid exhaust valve will not open until the chamber temperature reaches below boiling
point.
Do not attempt to open the sterilizer lid until the pressure is at 0psi.
Use the pressure relief switch to reduce the pressure inside the chamber to “0psi”. (refer to
page 35 for instruction how to use the pressure relief switch)
