6.2 Operating Test of Safety-Valve
Table 4: Safety-Valve
Start of the Test:
• Turn the knurled-screw
in counter- clockwise
direction
• After an evident audible crack stop turning
of the knurled-screw
• Now turn the knurledscrew in clockwisedirection back to start
position.
The audible crack while
turning the knurled-screw signals the functioning of the safetyvalve.
If during the test the crack is not audible, the safety-valve is
out of order.
In this case the safety-valve has to be replaced unconditional
before the next use of the sterilizer.
WARNING: A Cleaning or Repair of the safety-valve
can only be made by the manufacturer.
Any change or manipulation at the safety-valve, except the operating test, can be followed by a damage of the equipment or
in case to Explosion of the pressure chamber.

2. Preheating and after-heating temperature
Preheating: If the media sensor has been activated while
the „F“ key (start key) has not been depressed, the autoclave is preheated to an
„operating readiness“ temperature of 60°C.
After-heating: After sterilization the autoclave is cooled
down to 60°C, when the media sensor
remains activated. This temperature is
maintained until the autoclave is switched off
so that nutrient media can be further
processed.
5 Optional extras: Port for Documentation
The port for documentation of the sterilization cyclus only works
together with the MCS-processor.
It allows the transfer and documentation of sterilizationprocess
on an external PC.
6 Maintenance and Care
WARNING: It is imperative that maintenance and care
are completed according to the following table to prevent damage and injury and to achieve the required
sterilization result.

7. The autoclave is heated up to the entered setpoint temperature. A flashing dot at the bottom right-hand side of the
display indicates when the sterilization time has started.
CAUTION: Renewed depression of the "F" key will abort the
process.
8. The heating system is switched off when the sterilization
time has elapsed, and the autoclave cools down. been The
cooling down process can be accelerated when solids have
sterilized by slightly opening the exhaust steam valve
(WARNING: Not with liquids ⇒The autoclave is heated up
to the entered setpoint tem delayed boiling!).When the display shows ENDE the sterilization is ready. When you press
the button F the display shows the chamber temperature
again.

1.1 Explanation of symbols
DANGER: This symbol draws attention to a dan-
gerous electrical voltage. Non-observance through
direct or indirect contact can result in serious injury
and even death!
WARNING: This symbol draws attention to a dangerous situation (location). Before the device is operated it is imperative that these operating instructions are read and understood completely.
1.2 Acceptable risk
DANGER:
1. Removal of the control housing gives rise to the
danger of direct contact with live parts of the device.
2. Only qualified personnel are allowed to open the
control housing when the device is disconnected.
3. The autoclaves with electrical heater must only be
connected to an earthed, shock-proof socket conforming with the requisite safety requirements.
__________________________________________________

The MCS control (microcomputer) permits digital time and temperature control with a PT 100 sensor and an analogue pressure display. The data of the electrical heating system are either
230 V/2000 W/50 Hz (TKL-MCS 123) or 230 V/1500 W/50 Hz,
depending upon the given model. MCS control eliminates the
need for manual control, and it also means that the autoclave
does not have to be supervised during operation.
Follow the subsequent steps to complete a sterilizing cycle:
A: Preparations for operation
WARNING: Please observe the "Safety Instructions"
and "Acceptable Risks" (Chapters 1. and 1.2), but
particularly the section "Preparations for Operation".

page 23
WARNING: Preparation for operation:
1. Never sterilize in your autoclave :
⇒ packaged solid matter
⇒ fluids in closed containers
Closed containers may, in case of a sudden fall of pressure
(e.g. autoclave is opened at a temperature of over 70°C),
lead to a retardation of ebullition and explode.
⇒ dangerous fluids (see page 9)
2. Sterilization products that are sensitive to rust must only be
sterilized with alkalised fresh water. For this purpose add
2% of soda to the fresh water. Please note that alkalised
water will attack sterilization products made of aluminium.
3. Distilled water will eventually damage enamel. Consequently, only use tap water.
4. Sterilization results will be inadequate if the water level falls
short or exceeds the minimum and maximum quantities,
and there is an added risk of injury by emitted hot water.
Please refer to the corresponding details in these Operating
Instructions.
5. Pay attention:
⇒ that the rubber gasket is correctly seated when the autoclave is closed.
Leaks can result in inadequate sterilization.
6. Operation of the device without water can damage the heating system.
7. Ensure that sterilization products do not get into reaction
with the operating water.

2.6.3 Sterilization by boiling in water under
pressure
All steps and safety measures described in Section 2.6.1 must
be observed, together with the following additional requirements:
1. Fill the pressure vessel with tap water until the product that
is to be sterilized is adequately covered.
CAUTION: Never fill more than ¾ of the hight of pressure
chamber.
2. To avoid breakage, glass parts should be placed in the wa-
ter while it is still cold.
2.6.4 Other uses of the autoclave
1. The temperature must be below 100°C, and the valves must
remain open, when the autoclave is used for the cultivation
of nutrient media or as an incubator. The temperature must
be controlled by adjusting the heating source accordingly.
The autoclaves are not permitted to cultivate nutrient media,
which are used for In-vitro-diagnostics.
2. With oil-bath sterilization it is necessary to use appropriate
containers to hold the sterilization oil and the instruments
that are to be sterilized.
__________________________________________________
page 21
WARNING: After sterilizing:
1. Never open the lid while the autoclave is under
pressure. The hot steam can cause serious injuries to the hands and face.
2. For taking out the still hot sterilization products
always use gloves or a suitable pliers.
Indication: If there should be formed a vacuum during cooling
down, it can be removed by lifting whistle valve
cone. For autoclaves with MCS-controller the exhaust valve has to be opened.
A: After sterilizing solids:
1. Ensure that emitting steam is not directed at a person when
the steam pressure is vented.
_____________________________________________________
page 6
We recommend the use of our sieve tray or sieve basket (accessories) to achieve uniform heating of the liquid container.
For sterilization of liquids we recommend the use of a mediasensor for autoclaves with MCS-controller (see chapter 4).
2. The liquid container must be surrounded by an adequateamount of water to guarantee the best possible transmission of heat. (CAUTION: Never fill the pressure chamber
more than ¾ full!).
B: During operation
WARNING: Please observe the "Safety Instructions"
and "Acceptable Risks" (Chapters 1. and 1.2), but
particularly the section "During Operation".
The same steps as those described in Section 2.6.1 B must be
observed during operation and, additionally, the following
points:
CAUTION: To achieve the required sterilization effect, for auto-
claves without media sensor the sterilization time
has to be extended by additional time (see table
6),depending on the liquid volume for each container.
table 6: Additional time for sterilization of liquids

WARNING: Inspection, maintenance and care:
1. It is imperative that the cleaning, maintenance and
inspection instructions of these Operating Instructions are observed. Non-observance can result in inadequate sterilization and damage both the autoclave and the product that is being sterilized.
2. Never change autoclaves in any way, particularly
⇒ the safety valve
⇒ whistling valve
⇒ steam-regulating valve
The valves are works adjusted. Any change of the
settings can result in inadequate sterilization, damage the product that is being sterilized and the autoclave, and even cause the vessel to explode.
3. Non-observance of the autoclave checks stipulated
by the manufacturer can result in inadequate sterilization, damage the product that is being sterilized
and the autoclave, and even cause the vessel to explode.
4. The use of tap water will result in scaling. This will
damage the tubular heaters and increase the power
consumption of strip heaters. Regular descaling is
therefore essential.
5. The autoclave must be stored in an open condi-
tion so that mould cannot form inside the moist
autoclave.
_____________________________________________________

4. ⇒ adjust the whistling valve by its knurled screw to the required operating temperature (indicated in the cut-out of the
scale disc), e.g. 3 bar.
⇒ then open the pressure control valve by turning it clockwise until the stop point is reached. The autoclave must be
vented during the heating up stage.
⇒ the heating system can then be switched on at full capacity.
B: During operation
WARNING: Please observe the "Safety Instructions"
and "Acceptable Risks" (Chapters 1. and 1.2), but
particularly the section "During Operation".
1. The autoclave is adequately vented when a strong jet of
steam is being emitted by the pressure control valve (approx. 100°C thermometer display). Close the pressure control valve.
2. The acoustic warning signal of the whistling valve indicates
that the required operating pressure has been reached.
Close the whistling valve by turning it to the right until the
stop point is reached. (Please note: The figures of the scale
disc relate to the outgoing connection of the valve). Only
from this moment onwards does the sterilization time
commence.
WARNING: Autoclaves without MCS control must
be
constantly
supervised during the sterilization proc-
ess!
The steam pressure control valve may have to be readjusted
to ensure that the operating pressure is not exceeded or undercut (see safety instructions and acceptable risks)!
