having cracks or scratches.
Contravention is dangerous with likelihood
of burns or serious accident due to blowout
during removal of equipment.
Do not block the hole in the inside
of the chamber with articles to be
sterilized.
Contravention is dangerous with likelihood
of serious accident such as blowout from
the chamber because the pressure in the
chamber cannot be controlled when the
exhaust hole in the inside of the chamber is
blocked by articles to be sterilized such as a
sterilizing bag. Make sure that articles to be
sterilized are placed in the basket provided
etc. so that the vicinity of the hole is not
blocked.
Stop operation immediately when the
pointer of the pressure gauge reads
above the red line during operation.

When returning the autoclave or its
parts, or requesting repairs, disinfect
the autoclave or parts whenever
condition 1 or 2, given below, applies.
When the autoclave or any part of the
autoclave has been subjected to infectious
and dangerous material or radioactive
material.
When blood or other chemicals have
pooled in the autoclave or any part of the
autoclave, of a type judged to be dangerous
to personnel.
1:
2:
Be careful of high-temperature liquid
because it may boil suddenly.
The temperature of liquid falls more slowly
than that of the chamber and liquid may
boil as a result of a trigger such as physical
shock. When liquid is not dealt with
carefully, there is likelihood of scalds or
unexpected accident.
Do not operate the autoclave with
flammable or explosive articles in
place.
Contravention is dangerous with likelihood
of fire or explosion.
Do not leave contamination in the
inside of the chamber or sterilizing
water.

malfunction and cause deterioration of the
empty heating prevention function, which
may result in fire in case of empty heating.
Before carrying out preventive
maintenance work, remove the power
plug of the autoclave from the outlet.
Contravention is dangerous with likelihood
of electric shock. For models with which
a power plug is not provided, turn OFF
the breaker to which the power cable is
connected.
Stop operation when corrosion,
damage, or deformation is found in
the chamber, chamber lid, hinges,
hinge shafts, cover rings, lid hooks,
or lid hook catches.
Contravention is dangerous with likelihood
of death or serious accident due to blowout
during rise of the pressure. When an
abnormality is found, contact the dealer or
business institution of our company.
Stop operation when damage such as
cracks or deformation is found in the
chamber lid gasket.
Contravention is dangerous with likelihood
of scalds due to steam leakage. When an
abnormality is found, contact the dealer or
business institution of our company.
Unplug and check the power plug
regularly.
Failure to do so may cause a fire or
burnout.
After replacing the chamber lid
gasket, be sure to make a test run.
Make sure the chamber lid gasket is
properly replaced. Failure to do so may
cause burns as the unexpected hot steam is
escaping through the lid.
WARNING
Pay extreme caution when removing
sterilized articles as they are very hot.
Immediately after autoclaving, sterilized
articles can become very hot and must be
handled with extra care, otherwise cause a
serious burn injury or accident.

ー6ー
CAUTION
Drain water after sterilizing water
cools down sufficiently.
Contravention is dangerous with likelihood
of scalds because the sterilizing water is
heated immediately after operation.
Do not place the hands on the top
plate.
Contravention is dangerous with likelihood
of injury because hands may be caught by
the chamber lid.
Carry out preventive maintenance
work only after the temperature in
the chamber has fallen sufficiently.
Contravention is dangerous with likelihood
of burns due to high temperature.
Be careful of steam coming from the
vicinity of the steam exhaust opening
during operation.
Contravention is dangerous with likelihood
of scalds due to high temperature.
Be careful of steam coming from the
vicinity of the safety valve during
operation.
Contravention is dangerous with likelihood
of scalds due to high temperature.
Handle the spring band of the gasket
gland with extra care since the elastic
force may cause unexpected injuries.
Be sure no other people are in the
immediate vicinity when handling the
spring band.
Do not use a cable which exceeds
the length of three meters when
connecting to a data output device.
Using the cable exceeding three meters may
introduce more noise and cause abnormal
operation or give adverse effect to other
electric devices.
Do not touch the thermal head
because it can be very hot after
printing.
Failure to do so may cause burn injury.
Be careful not to touch the paper
cutter blade.
Failure to do so may cause injury.

2. EXPLANATION OF THE AUTOCLAVE
2-1. Operating Principle
The high-pressure steam sterilizer is a autoclave used for sterilizing articles with saturated
steam under a pressure which is higher than atmospheric pressure.
After commencement of operation, sterilizing water in the chamber is heated by the element
heater at the bottom of the chamber to generate steam. Steam generated through heating drives
air from the chamber and warms the inside of the chamber. When the temperature sensor
in the chamber detects that the temperature has risen to the specified level, this temperature
is maintained for a specified time. Residual air in the chamber is driven out through this
operation. When the specified time has elapsed, the valve closes to carry out heating.
When the temperature sensor detects that the temperature has risen to the specified level,
the timer is activated to maintain a constant temperature. When the set sterilizing time has
elapsed, the element heater stops. The sterilizing action is determined by the three elements:
temperature, humidity, and time applied to articles to be sterilized during this time.
When the temperature in the chamber falls, the valve opens to return the pressure in the
chamber to the atmospheric level. When the temperature sensor detects 60 °C, all processes are
completed and completion is indicated by a buzzer sounding and by the indication lamp.
When an abnormality is generated in the autoclave, it changes to a safer status and the
abnormality is indicated by an error code display and by a buzzer sounding.
