Cautions in Using with Safety
Fundamental Matters of "WARNING!" and "CAUTION!"
CAUTION!
When opening the cover...
Make sure that the pressure of equipment has decreased to 0(zero) MPa before
opening the cover. Generally the cover does not open due to the safety lock
mechanism under the high pressure condition. The high-temperature and pressure
vapor blows out if the cover is forced open under high pressure, which may cause a
burn injury. A large amount of vapor blows out from inside of the chamber when
opening the cover just after the sterilizing operation has completed (when the
temperature inside the chamber is high). Do not put your hands and face close to the
cover.
When draining water...
Make sure that the pressure of equipment has decreased to 0(zero) MPa before draining the sterilizing
water. The hot water blows out if the valve is opened under high pressure. The sterilizing water
remains very hot just after the sterilizing operation has completed even the pressure reading is 0(zero)
MPa. Drain the water after it is sufficiently cooled down.
Do not touch the drain bottle during operation
A drain bottle, which contains hot water during and just after operation, is placed inside the door in the
front face of equipment. To avoid a burn injury, remove the bottle after the water is sufficiently cooled
down. Do not open the door during the operation of equipment.
Make sure to drain the water when the water level comes to the seal position
The hot water or vapor may blow out from the drain bottle if the equipment is operated with too much
drain water (water level above the seal position). (Refer to 17 of “Precautions for continuous operation”
in Page 13 for details.)
Securely fix the silicon plug of the drain bottle
Securely fix the silicon plug when installing the drain bottle. The hot water or vapor may blow out from
the drain bottle if the equipment is operated with the plug loosen. (Refer to 6 of “Set the drain bottle” in
Page 10 for details.)
Pour off the water inside the vapor cup after every operation
The cup becomes full with the water after the equipment is operated a few times. Pour off the water
inside the cup after every operation. The hot water or vapor may blow out from the drain bottle if the
cup is full with water. (Refer to 14 of “Attach the vapor cup” in Page 12 for details.)
Do not touch the hot section
Some sections on the equipment such as the circumference of cover or drain bottle are very hot during
or just after the operation of equipment. Do not touch these sections to avoid burn injury.

Cautions in Using with Safety
Fundamental Matters of "WARNING!" and "CAUTION!"
When taking the sterile samples from the chamber...
Sufficiently remove the vapor inside the chamber before taking the sterile samples from the chamber.
Wear heat-resistant leather gloves to take them from the chamber to protect your hands from
high-temperature samples.
Do not touch the heat releasing outlet
Do not directly touch the heat releasing outlet located around the outer covering. The vapor may blow
out from the safety valve by an accident during sterilizing operation. Do not block the outlet.
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and the main
power. If this procedure is not followed, fire or electrical shock may be caused.
When power failure occurs...
The lock lever on the cover goes into locked state for safety reasons when the power is turned off due
to a power failure. The state is automatically cancelled when the power is turned on and the pressure
inside the equipment decreases.
Do not operate the equipment without supplying sufficient amount of water
Do not operate the equipment without supplying sufficient amount of water. The heater is exposed to
the open-air if the amount of water supplied is insufficient, which causes a deterioration or breakage of
equipment. Make sure before operation that the appropriate amount of water is supplied inside the
chamber. (Refer to 9 of “Pour water into the chamber” in Page 11 for details.)
Do not open the panel on the outer covering
Touching the interior portion of equipment may cause an electric shock, burn injury, fire disaster or
equipment failure.

Installation Procedure
11 Set the sterile samples
• Set the samples to the chamber, putting them into the attached rack or cast (sold separately).
• Put the sample or sterilization bag into the chamber so they should not block or cover the
sensor inside the chamber, exhaust outlet and end connection to pressure gauge. If they are
blocked or covered, the vapor cannot be discharged and the equipment cannot be operated
correctly. Do not spill the samples when taking them out from/putting them into the chamber.
The failure in piping system, bad smell or dirt may result in.
• In case liquid such as medicinal solution or medium is sterilized, the amount of liquid should be
60% or less of the capacity of container. They may be boiled over if too much quantity is
supplied.
• Widely open the opening of sterilization bag when used. If it is closed, the samples are
insufficiently sterilized.
12 Close the door before operation
• Make sure to close the door of equipment before operation. If the door is not fully closed, the
drain bottle falls down and may cause a burn injury. Do not open the door during operation.
Before Using This Unit

Installation Procedure
16 Precautions for drainage
• Before draining the water, make sure that the pressure, equipment temperature and water
temperature inside the chamber have decreased sufficiently.
17 Precautions for continuous operation
• When operating the equipment continuously after sterilization is completed, leave the
equipment for about 15 minutes with the cover opened to sufficiently lower the temperature
inside the chamber and then close the cover. If the temperature is high, the cover may not
close due to high internal pressure of chamber.
• Before operating the equipment again, check the water level of drain bottle by observing it from
the observation window to make sure that it is below the level indicated by the drain level seal
on the door. In case the water level of drain bottle is above the drain level seal, drain the
water until the water level comes to 1500cc of the water level gauge, indicated on the side face
of bottle. The hot water or vapor may blow out from the drain bottle if the equipment is
operated with too much drain water (above the seal position).

Reference Data
Sterilizing operation using disposal bag for biochemically dangerous object
① Open the opening of sterilization bag so the vapor can be easily entered into it.
Secure the bag with a wire rack so it should not fall down during operation.
② The height of bag should be about two-thirds of chamber. If it is too high, the
vapor cannot be easily entered into it, or it blocks the vapor outlet at the upper
part of chamber, which may cause insufficient sterilization.
③ The preset temperature should be the upper temperature limit of bag to be used.
④ The preset time varies depending on the quality and quantity of sterile samples. Refer to the
following data for the preset time.

right away, and then turn off the circuit breaker and the main power. Immediately contact a
service technician for inspection. If this procedure is not followed, fire or electrical shock may
result. Never perform repair work yourself, since it is dangerous and not recommended.
Measure for flammability and handling of flammable solvent
This unit is not designed as the explosion-proof construction. Pay special attention to the
handling of the sample to be handled with this unit on the consumption with the explosive
material, flammable material, and similar ones. The flammable material may be vaporized by
leaving it at the temperature higher than room temperature, and could cause the fire or
explosion. When handling such material, provide ventilation with enough before the operation.
(Refer to page 56 “List of Dangerous Substances”.)
Keep the unit well-ventilated
Keep the heat releasing outlets in the side and back of the unit open during operation. If they
are closed, the inside temperature of the unit may increase, its performance may deteriorate, or
an accident, malfunction or fire may result.
Exercise care not to allow a liquid to get on the unit
Exercise care not to allow a liquid to get on the unit or enter the unit through the heat releasing
outlets in the side or back of the unit. If it enters the unit, stop the operation. Otherwise. an
accident, malfunction, electric shock or fire may result.
Do not drop metallic pieces into the unit
Do not drop metallic pieces, such as clips, staples and screws, into the unit. If such a metallic
piece has dropped into the unit, turn it off. An accident, malfunction, electric shock or fire may
result.

Do not place or drop anything on the unit
Do not place or drop anything on the unit. Since the unit contains precision components, it may
malfunction due to vibration, impact, etc.
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and
the main power. If this procedure is not followed, fire or electrical shock may be caused.
Countermeasure for stop operation during night or long-term stop
Turn off the power of earth leakage breaker and disconnect the power cord from the power
source before stopping the operation of equipment overnight or for a long time.
Do not touch the hot section
The temperature on the cover and top board on the chamber are very hot during operation or just
after operation is completed. Do not touch these sections to avoid a burn injury.
When opening the cover…
Make sure that the pressure gauge reading has decreased to 0(zero) MPa before opening the
cover. Open the cover slow carefully. The high-temperature and pressure vapor blows out if
the cover is opened during high pressure.
When opening/closing the door…
Do not put your hands or face into the traveling range (space) of door when it is opened or
closed. The door may contact, which may cause an injury.
When draining water…
The water in the chamber is very hot just after operation is completed. Be careful not to get a
burn injury. Drain the water after the water is sufficiently cooled down.
Do not drain water during operation. The hot water blows out if the drain valve is opened while
the pressure is increasing.
Do not damage the packing on the cover or flange on the chamber
Damage or dirt on these areas may cause the vapor leakage, which may be the cause of burn
injury. Keep these sections always clean. Do not damage them with the rack when taking out
and putting in the sterile samples. The packing degrades wit time. It must be replaced if vapor
leak occurs frequently. In this case consult with the selling office where you purchased or our
sales office.
Replace the packing early
The packing is a consumable. If it shows the sign of damage or hardening, replace it early.
Please consult with the selling office where you purchased or our sales office for the replacement
of packing.

If the valves rotate or droplets are adhered, the piping is loose. Tighten it securely.
② Make sure that the nut on the joint does not rotate when turned clockwise with a screw wrench.
Make sure that no water droplets are adhered around it.
Piping
If the valves rotate or droplets are adhered, the piping is loose. Tighten it securely.
③ Make sure that damages do not exist on the piping. Make sure that no water droplets are
adhered around it.
If the conditions above, especially water droplet, are observed on the areas other than the joint, the
piping must be replaced.
Close the cover.

① Set up/connect the respective devices referring to the figure above.
② Pressurize the chamber inside. When the corrected pressure gauge reads 0.05MPa, 0.1MPa
and 0.15MPa, compare the readings between the corrected pressure gauge and the pressure
gauge on the main unit.
The tolerance of pressure accuracy compared should be within ±0.005 MPa. If it is beyond this
range, replace the pressure gauge.
① In order to confirm the operating pressure of safety valve, pressurize it to 0.15 MPa first and
then pressurize it gradually.
② The valve should be actuated at the pressure between 0.25 and 0.26 MPa. Do not pressurize
it with 0.27 MPa or more.
If the valve is actuated in the range other than the above, adjust it according to the procedures
below.

Water leak on solenoid valve/exhaust valve
② Pressurize the chamber inside. When the corrected pressure gauge reads 0.05MPa, 0.1MPa
and 0.15MPa, compare the readings between the corrected pressure gauge and the pressure
gauge on the main unit.
The tolerance of pressure accuracy compared should be within ±0.005 MPa. If it is beyond this
range, replace the pressure gauge.
Check the temperatue accuracy by using either of following methods.
① Fix a corrected temperature sensor (a recorder attached) or maximum thermometer near the
chamber temperature sensor inside the chamber. Perform the sterilizing operation at a preset
temperature of 135℃ with no load. Compare the temperature inside the chamber displayed
on the equipment with that indicated by the corrected thermometer. The temperature should
be between 135 and 137℃ to the preset temperature of 135℃. Use the service plug (internal
thread of R1/4) to fix the temperature sensor.
② Perform sterilization and compare the pressure and temperature at sterilization process. The
relation between the temperature inside the chamber and saturated pressure under the
atmosphere of 1013 hPa are as follows.
Temperature accuracy
115℃: 0.068MPa, 133℃: 0.187MPa
121℃: 0.104MPa, 134℃: 0.202MPa
126℃: 0.138MPa, 135℃: 0.212MPa
131℃: 0.170MPa, 136℃: 0.221MPa
132℃: 0.171MPa, 137℃: 0.231MPa
