Vacuum Check: Ensure the vacuum indicator is in the green sector for proper operating vacuum. Emergency Opening: If the actual temperature is at least
, depressing the [B] key should open the furnace head within 30 seconds. Troubleshooting & Maintenance
Maintaining an older P90 requires attention to mechanical and electronic shifts over time.
Calibration: Temperature characteristics can shift due to contamination. It is recommended to recalibrate periodically using an independent system or the ATK2 Temperature Checking Set.
Vacuum Loss: Often caused by a contaminated vacuum valve or O-ring. Weekly cleaning of the firing plate and head seal is recommended.
Manual Head Issues: Never force the furnace head shut manually; this can damage high-torque electric drive motors. If the head stalls, check for obstructions or perform a factory reset to re-align sensors.
Dehumidification: Run a dehumidification program if moisture enters the chamber, which typically happens if the head is left open while the unit is off. Programat®

is a classic dental furnace known for its reliability in firing dental ceramic materials. While it is an older model, maintenance and proper operation remain key to its performance. Manual & Service Support
Finding a digital version of the original P90 manual can be challenging as it is often not available for direct download on the modern web. For specialized technical repairs or specific program data, it is highly recommended to contact your local Ivoclar Service Center for official documentation or guidance. Essential Maintenance Tips Post-Reset Step: You must re-run the calibration program
For general upkeep similar to other Programat models like the P310, follow these standard maintenance practices:
Calibration: Regularly calibrate the furnace (using sets like the ATK2) to ensure temperature accuracy during firing.
Cleaning: Disconnect power and wait for the unit to cool completely before cleaning. Avoid using solvents.
Visual Checks: Inspect the firing chamber for damage to the insulation and ensure sealing surfaces are clean and free of contamination. Safety Precautions:
Never touch the thermocouple or quartz tube with bare skin, as grease can damage them. Do not operate the furnace without a firing table. Troubleshooting Common Issues
If the unit malfunctions, standard troubleshooting includes:
Vacuum Failures: Check that the vacuum hose is securely connected and that the firing chamber seal is tight.
Power/Start-up Errors: If the self-test fails, switch the unit off and on again. Ensure the supply voltage matches the rating plate.
"Service" Hint: On newer Programat generations, a service hint appears after 1200 firing hours or two years, recommending a professional technical inspection.
The Ivoclar Programat P90 is a classic fully automatic vacuum ceramic furnace, first introduced in 1987. It is highly regarded for its reliability and was the first in the Programat line to feature a membrane-sealed keypad for entering parameters. Key Technical Specifications

Proper installation is critical for ensuring vacuum integrity and long-term operation.
Control Unit Attachment: Ensure the control unit is pushed into the furnace base until the locking bolts engage with an audible click.
Vacuum Connection: Use the dedicated vacuum recess for the hose and ensure the pump plug is securely connected to the base socket. The vacuum pump should always be placed in a well-ventilated area.
Furnace Head Mounting: Fit the mounting lug over the hinge pins and push down evenly so the sealing ring rests correctly on the furnace base rim. Essential Operating Controls
The keypad allows for direct selection of all firing parameters. START (Green Key): Begins the selected program. STOP (Red Key):
Press Once: Stops an active program, heating, or the buzzer. Press Twice: Stops the vacuum.
Open/Close Keys: Used to move the furnace head. Note: These cannot be operated while a program is running unless you press STOP first.
P Key: Allows for the entry and selection of program numbers (0–90). Maintenance and Calibration
Routine care is necessary to prevent temperature shifts caused by contamination in the firing chamber.
Silver Test Calibration: The established method for checking temperature accuracy. The user adjusts the temperature up or down based on the results of the silver wire test.
Cleaning: Use only a dry or slightly moist cloth. Never use solvents or compressed air, as the insulation contains ceramic fibers that can release hazardous dust.
Vacuum Seal: Regularly clean the sealing ring in the furnace head and the rim on the base to ensure they remain undamaged and free of debris. Important Safety Warnings
Avoid Hand Opening: Never open the furnace head by hand; always use the electronic control keys to avoid damaging the motor mechanism.
Burn Hazard: Do not reach under the furnace head or touch the quartz tube/thermocouple during operation. including detailed manuals
Ceramic Fibers: The firing chamber contains ceramic fibers. If the heating muffle must be changed, wear protective gear (goggles, gloves, and FFP3 mask) to avoid inhaling dust. IVOCLAR VIVADENT Programat P90 buy on Bimedis
The Ivoclar Programat P90 is a legacy ceramic furnace released in 1987, known for being the first Programat model with a membrane-sealed keypad. While a single "fixed" manual does not exist for this vintage device, the following resources and steps address common maintenance and technical issues. Common Error Codes & Troubleshooting
The P90 often displays specific error codes on its 7-segment display when internal components fail.
Er99: Indicates a "control unit malfunction". This typically occurs after replacing internal batteries or heating elements (muffles). If standard programs are lost or display garbled characters, internal parameters may need a factory reset.
Er03: This error appears if the pre-set vacuum switch-off value exceeds the pre-set temperature (
Heating Issues: If the furnace fails to heat, check the heater fuse first. If the fuse is intact, the heating muffle may be worn out and require replacement. Essential Maintenance Steps
For aging units like the P90, regular calibration is critical for firing accuracy.
Silver Test (Calibration): Use the Ivoclar ATK2 Automatic Double Range Calibration Set or a traditional silver wire test to ensure temperature accuracy. Vacuum System: Ensure the vacuum hose is at least long and not shortened, as this affects vacuum pressure.
Battery Replacement: The P90 uses an internal battery to store program memory. If the unit loses saved programs after being powered off, this battery likely needs replacement by a technician. Official Documentation & Support
