tive conductor connection may lead to danger for the user in case of malfunction. Deliberate interruptions are not tolerated. Materials developing harmful gases must not be ﬁred.

Warnings regarding the dismounting of the heating muffle

This product contains ceramic ﬁbres and may release ﬁbre dust. Fibre dust has proved to be carcinogenic in animal experiments. The correspon-

ding EU Safety Data Sheet must be observed.

The heat insulation of the ﬁring chamber in the Programat P300 & P500 consists of ceramic ﬁbres. After prolonged use of ceramic ﬁbres at temperatures of over 900 °C (1652 °F), silicogenic substances (Cristobalite) may be produced. In certain cases, e.g. upon changing of the heating muffle, the possible resulting dust exposure may cause irritation of the skin, eyes, and respiratory organs. Therefore, proceed as follows when changing the heating muffle:

– Make sure the corresponding staff wears long-

sleeved clothing, as well as headgear, goggles, and gloves.

– Place suction equipment at the source of the

dust or, if not possible, provide the staff with FFP3 facemasks or similar items.

– Once the procedure has been completed, any

dust possibly adhering to exposed skin must ﬁrst be rinsed off with cold water. Only after that should soap and warm water be used.

– The corresponding work clothes should be

washed separately.

Warning

The insulation on this product contains refractory ceramic ﬁbres (RCF) which pose a possible cancer hazard, if agitated and inhaled. May be irritating to the skin, eyes or respiratory tract if insulation is cracked or corrupted.

California Proposition 65 Warning: ”This product contains Refractory Ceramic Fibres, a substance known to the State of California to cause cancer.”

Disposal:

The furnaces must not be disposed in the normal domestic waste. Please correctly dispose of old furnaces according to the corresponding EU council directive.

7. Maintenance, Cleaning, and Diagnosis

This chapter describes the user maintenance and cleaning procedures for the Programat P300. All the other tasks must be performed by qualiﬁed service personnel at a certiﬁed Ivoclar Vivadent Service Center.

7.1 Monitoring and maintenance

The time for these maintenance procedures depends on the frequency of use and the working habits of the users. For that reason, the recommended times are only approximations.

daily Firing chamberCheck the quartz glass cylinder to make sure the quartz glass is not defective.

twice a year

Firing chamberCheck temperature. Use the temperature checking set to check and adjust the temperature in the furnace.

weeklyKeypad (10)Check the keypad for visible damage. If the keypad is damaged, it has to be replaced

by a certiﬁed Ivoclar Vivadent Service Center.

weeklySealing rims of the furnace head (2) and the furnace base (1)

Check if the sealing rims of the furnace head and the furnace base are clean and undamaged.

monthlyInsulation (3)Check the insulation for cracks and damages. If the insulation is worn down it has to

be replaced by a certiﬁed Ivoclar Vivadent Service Center. Fine hairline cracks on the surface of the insulation are harmless and do not inﬂuence the function of the furnace in a negative fashion.

WhenPartWhat

This furnace has been developed for typical use in dental laboratories. If the product is used in a production enterprise, for industrial applications, and for continuous use, premature ageing of the expendable parts has to be

expected.

The expendable parts are as follows: – Heating muffle – Insulation material

Expendable parts are not covered by the warranty. Please also observe the shorter service and maintenance intervals.

If the furnace head is replaced, the furnace must be calibrated.

7.2 Cleaning

The furnace may only be cleaned when it is cool, since there is a burn hazard. Do not use any cleaning solutions.

The following parts have to be cleaned from time to time:

*Never clean with compressed air!

Item Frequency: Cleaning material:

Housing (9) and furnace if required soft, dry cloth head (25)

Keypad (10) weekly soft, dry cloth

Cooling tray daily cleaning brush * (34)

Insulation (3) daily cleaning brush *

Sealing rim of the furnace daily cleaning brush and head (2) and sealing a soft cloth surface (1)

7.3 Test programs

Press the 'cog-wheel' key (Settings/Information)

– Vacuum pump test program:

With this program, the vacuum performance of the furnace vacuum system can be automatically tested. For that purpose, the achieved (minimum) pressure in mbar is measured and indicated. If the pressure value is below 80 mbar, the vacuum performance of the system is adequate.

– Keypad test program

– Heating muffle test program

– Dehumidiﬁcation test program

– Cleaning program

7.4 Stand-by

We recommend keeping the furnace head closed, especially if the temperature drops below 150 °C (302 °F).

7.5 Dehumidiﬁcation program

The condensation of water in the insulation of the ﬁring chamber and the vacuum pump will result in a lower vacuum and thus to impaired ﬁring results. For that reason, the furnace head should be kept closed when the furnace is switched off, in order to prevent the absorption of humidity. Start the dehumidiﬁcation program if required (humidity in the insulation).

7.5 Calibration

Furnace calibration (Silver Test)

The sheathed thermocouple may be subject to changes with affect the furnace temperature, depending on the mode of operation. Check furnace temperature with the ‘Silver Test’ at least once a year and adjust if necessary. For

that purpose, the furnace features a special calibration program.

Procedure:

a) The Furnace must be at operating temperature (switched on for

at least 60 minutes) and have a stand-by temperature of 403 °C (757 °F).

b) Press and keys to

enter the Options menu.

Then press key until the Display shows this screen:

To select the calibration program press the ENTER-key. The following is displayed:

c) Insert silver wire into the Ivoclar

Vivadent sample holder.

d) Place the sample holder with the

silver strip in the centre of the ﬁring plate (6).

e) Press START (if error message Error 14 appears, the furnace

temperature is still too high fort he ‚Silver Test’ (>410 °C/770 °F)). The furnace closes automatically at the correct temperature and the program starts.

If the silver wire has started to melt (and has a ‚pitted’ appearance) at the end of the program, the furnace temperature is correctly calibrated (Figure B) If not, recalibration is necessary.

Recalibration

A change in temperature of ”+/-” 100 °C (180 °F) is possible in the Programat P300. Select calibration program to activate the calibration keys + and –. The program must not be started for this purpose. The latest calibration value is indicated on the Display.

– If the silver wire has not started

to melt after the Silver Test, recalibrate using the +key (Figure A)

– If the silver wire has melted

down to a ball after the Silver Test, recalibrate using the –key (Figure C).

Every time a calibration key is pressed, the set temperature changes by 1 °C (1.8 °F) Experience has shown that a recalibration of 5 °C (9 °F) is appropriate, which means pressing the relevant key ﬁve times.

While the calibration keys are in use, the calibration value in °C (°F) is shown in the Display. Entering the calibration value does not have to be conﬁrmed with ENTER. We recommend that you do not recalibrate the furnace immediately before it reached the holding temperature or during the holding time of the Silver Test program. Repeat the Silver Test until the silver wire starts to melt correctly (Figure B).
