PRESTIGE MEDICAL 210048 (01) PDF DOCUMENT

Before using the PRESTIGE MEDICAL 210048 autoclave, ensure that you read and fully understand the operating instructions.

This model is designed to operate at 121 +2°C for 22 minutes, for the sterilization of culture media. Please note that the Classic Media should not be used to sterilize wrapped instruments or porous loads. This cycle is not recommended for the sterilization of medical or dental instruments. TST Strips are not supplied with this model.

When sterilizing media, to ensure the safe operation of the autoclave and to avoid damage to the media, DO NOT manually vent the pressure by operating the pressure release valve at the end of the cycle. As an added safety feature, the lid interlock has been set to release only when the temperature of the chamber contents has dropped to 80°C or below.

Together with the PRESTIGE MEDICAL 210048 unit and operating manual, you will find the following:

Electrical mains cord

Instrument furniture

Spare fuses x2 (when fitted)

WARNING! Do not touch body or lid as these parts become hot when the autoclave is in operation.

WARNING! Mains outlet MUST BE GROUNDED (EARTHED). The mains plug should always be easily accessible as it is to be relied upon as “the means of disconnection”.

1. Connection.

Attach the cable supplied to the rear of the unit and plug into an EARTHED mains electrical socket of the CORRECT voltage.

2. Water.

Fill the unit to the water level line on the inside of the chamber with 0.75 litres of distilled or de-ionised water. DO NOT USE TAP WATER OR OVERFILL.

3. Loading (Media).

Place media containers into the instrument basket, and place in the unit. When using the basket, always place the metal ‘V’ support in the bottom of the unit so ensuring load is not in the water.

4. Closing.

Always place the lid on the autoclave with the Depressurization Valve (A) in the open position. Align the arrows on the lid and body (F1) and with the interlock button (E) pressed down turn in a clockwise direction ensuring it is completely closed (F2). Release the interlock button. Close the Depressurization Valve (A).

5. Power on.

Switch the unit on at the mains. Light L1 illuminates GREEN.

6. Temperature.

The 121°C temperature is automatically selected when the power is turned on.

7. Starting.

Press the cycle start button (B) to start the sterilizing cycle. Light L2 illuminates ORANGE and may flash. As the temperature rises, air will be displaced by steam through the Air Bleed Device located in the lid, until it closes with an audible “click”, sealing the unit.

Sterilizing temperature is reached when: Light L3 illuminates ORANGE and L2 flashes ORANGE.

The sterilizing cycle is completed when: The internal buzzer sounds and Light L4 is illuminated GREEN.

8. Depressurizing.

Once sterilizing has finished the unit should be left to automatically cool down without opening the pressure release valve.

9. Unlocking.

Once the temperature has reached a safe level and is below 80°C the interlock will release and the lid can be unlocked. Remove the lid by pressing down on the interlock button (E) and turning the lid in an anti-clockwise direction, aligning the arrows (F1 & F2).

10. Unloading.

Lift off the lid, gently place upside down on a solid work surface and leave to cool. Ensure the Depressurization Valve (A) is in the closed position to avoid damaging it. The basket containing the sterilized media can now be lifted out of the unit with care. Allow 5 minutes for the lid to cool down before replacing as per Step “4”.

DO NOT USE THE MEDIA IF A COMPLETE STERILIZATION CYCLE HAS NOT BEEN ACHIEVED.

To ensure your PRESTIGE MEDICAL 210048 gives you years of service, it is important to remember a few “do’s”.

1. …you read these instructions and always follow the operating sequence.

2. …the media will withstand the sterilizing temperatures selected, bottles are not sealed and screw tops are loose – do not overload the autoclave.

3. …the water level is maintained regularly with clean distilled or de-ionised water only.

4. …the unit is in a “draft free” environment and is positioned not less than 250mm from adjacent walls.

5. …you only use green sealing gasket (219500) and that it is changed at the end of its life, if visibly damaged, or when shrinkage has occurred.

6. …the lid is securely closed when the unit is not in use, to avoid the risk of accidental damage. Never leave in position (F1).

7. …you record the temperature and pressure readings for each cycle completed, to ensure they remain constant between cycles. Check readings against those quoted in the “Technical data” section.

8. …you quote your model details, serial number and date of purchase when contacting Prestige Medical or your supplier.

Do not….

1. …lose this operating instruction manual.

2. …add any chemicals whatsoever to the water.

3. …attempt to sterilize volatile substances, toxic materials or inappropriate loads.

4. …place the unit on heat sensitive surfaces ie polished wood or glass.

5. …open the Depressurization Valve (A) during the sterilization cycle.

6. …leave the Depressurization Valve (A) in the “open” position when placing the lid upside down on a work surface.

7. …immerse the unit or electrical cord in water when cleaning.

8. …use abrasive materials or lubricants when cleaning.

9. …drop or abuse the unit.

10. …use in areas of risk associated with flammable materials or gases.

11. …attempt to change any fuses until the unit has been unplugged from the mains. These operations should only be undertaken by a qualified person.

12. …reach over the unit when removing cover, to do so may cause burns from rising heat and steam.

13. …cover lid or obstruct steam venting area when manually depressurizing.

Green Sealing Gasket Care and Maintenance:

1. Remove from inside the lid and clean with warm, soapy water.

2. Rinse thoroughly, shake dry, do not wipe.

3. Replace in the lid by tucking evenly under all lugs. It may appear slightly wrinkled until used.

4. Replace when it begins to show signs of leakage.

Autoclave Care and Maintenance:

6. If a new gasket leaks, or a persistent leak develops, gently clean the sealing surface of both the lid and body of the unit with a “Scotchbrite” scrubbing pad making sure you do not remove any metal. Rinse both surfaces, but do not dry.

7. Clean both interior and exterior with warm soapy water ensuring electrical parts are kept dry.

8. Monitor the first cycle of the day to check the Air Bleed Device which is located inside the lid, audibly “clicks” shut.

9. Prestige Medical recommend that your unit is calibrated at six monthly intervals.

10. Lubricate underside of body lugs with “vaseline” if the lid becomes stiff. DO NOT LUBRICATE GASKET.

This corresponds to Fault 1: No power to unit.

The L1 light fails to illuminate.

Check for defective socket.

Check for power to socket.

Ensure lead is connected to electrical socket.

This corresponds to Fault 2: Low water or boil dry. The L5 light flashes RED.

Allow unit to cool before refilling to the correct level.

Disconnect from mains then reconnect and repeat cycle.

If the fault repeats with sufficient water, arrange for a service engineer to visit.

This corresponds to Fault 3: Sterilization failed to be achieved.

The L4 light fails to illuminate GREEN and there is no audible buzzer.

Disconnect from mains then reconnect and repeat cycle.

If the fault repeats arrange for a service engineer to visit.

This corresponds to Fault 4: Steam or water leaks from under the lid. This can be due to two reasons:

i) Worn or dirty gasket.

Wash gasket and sealing surfaces on the body and lid as described under “Care and Maintenance”. If the fault persists, replace with a new gasket.

ii) Incorrectly closed lid.

Ensure the unit is fully depressurised by opening Depressurisation Valve (A). Remove lid and re-fit carefully. Disconnect from mains, reconnect and repeat cycle.

This corresponds to Fault 6: Excessive steam or water leaking from Depressurisation Valve (A).

This is caused by the Depressurisation Valve (A) being in the “OPEN” position.

To remedy this, close the Depressurisation Valve (A).

In the unlikely event that something should go wrong, the PRESTIGE MEDICAL 210048 has incorporated a number of safety features to ensure it remains safe at all times.

Safety features:

1. Located to the rear of the lid, beneath the cover, is a spring called the Gasket Offset Device (GOD Spring), designed to prevent pressure building up if the lid has been incorrectly fitted. DO NOT TAMPER WITH THIS SAFETY DEVICE.

2. If for any reason, the temperature falls below the minimum required sterilizing temperature, resulting in the Sterilizing light (L3) switching off, the cycle timer will re-start from zero once the correct temperature has been restored.

3. If there is an electrical or electronic failure resulting in a build up of pressure – in excess of normal operating pressure – one or all of the following safety features will be activated:

i) The Depressurisation Valve (A) will loudly and rapidly “vent” steam.

ii) The gasket will “extrude” through the slot in the rear of the lid rapidly releasing excess pressure and steam.

iii) A non – resettable thermal fuse located in the base of the unit will “melt’ at a pre-determined temperature, disconnecting the power.

Should any of the devices listed above activate, please observe the following steps:

a) Do not touch the unit.

b) Switch off at the wall socket and un-plug.

c) Allow temperature and pressure to drop before i) touching the unit and ii) removing your instruments.

d) Do not attempt to re-start the unit.

e) Arrange for an immediate service.
