Cautions in Using with Safety
Fundamental Matters of "WARNING!" and "CAUTION!"
UCAUTION!
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 temperatur
e 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 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.
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.

Close the drain valve at the bottom
on the
left side face of main unit.
Water leak
occurs
if not fully closed, which may cause
the burn
injury no-load (water) operation.
The d
rain valve and lead it to the
draining site.
2 Pour water into the chamber
•
Before setting the sterile samples, pour water into the chamber to the water level gauge (notch)
position.
•Insufficient water may cause the no-
load (water) operation. Check the water level every time
before operation. Refill it befor
e the level becomes too low. Water is required to be poured at
dissolution operation, as well as sterilizing operation.
•When the water level lowers, the equipment
cuts off the heater. Depending on the conditions of
equipment, however, the detection require
s too much time, which may cause the heater
deterioration. Refill water before the water level becomes too low.
Refer to the right table for the quantity of water to be refilled.
3 Use distillated or purified water for sterilizing water
•Fill distillated o
r purified water inside the chamber. Tap water may be used. Calculus generate
inside the chamber when tap water is used. Frequent cleaning is therefore required.
•
Do not use well water. It may cause the corrosion or dirt inside the chamber.
4 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 connectio
n 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 or
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.

Operation Method
Apparatus/Liquid Sterilization Course
0B★In order to ensure the sterilization effect, the lower
exhaust valve knob should be turned to the micro
exhaust state (Figure 21) during the heating, pressure
rising and sterilization process to keep a small amount
of steam constantly discharged from the
cylinder, so
that the temperature in the cylinder can become
uniform.
When the heater starts to work, both the
sterilization temperature lamp and the heating
lamp on the control panel light up, indicating
that the sterilizer has entered into the operation
state of heating, temperature and pressure
rising (Figure 19). When the temperature in the
cylinder rises to be about 102℃, the interlock
indicator lamp will turn to be normally ON
(Figure 20).
When the temperature of sterilizer rising to the
set temperature, the sterilizing lamp and the
sterilization time lamp on the control panel light
up, the working lamp turns to blink, and the
sterilization countdown appears in the display
window (Figure 22), indicating that the
sterilization articles are being sterilized inside
the cylinder of sterilizer.
The sterilization countdown is over, the word
"END" appears in the display window, the END
