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.

1.1 Explanation of symbols

DANGER: This symbol draws attention to a dangerous 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.

__________________________________________________ page 2

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".

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.

_____________________________________________________ page 4

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 water 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 autoclaves without media sensor the sterilization time has to be extended by additional time (see table

6),depending on the liquid volume for each container.

__________________________________________________ page 19

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.

_____________________________________________________ page 8

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 process!

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)!
