7-segment display located above the parameter head, navigated via numeric membrane keys. Core Features Automated Functions:

Includes automatic opening of the furnace head and a slow cooling function to prevent thermal shock in ceramic restorations. Closing Time Adjustment:

Users can adjust the closing time of the furnace head to optimize pre-drying. Real-time Monitoring:

The display shows both the actual temperature and the setpoint value simultaneously. Ivodent Magyarország Maintenance & Troubleshooting

To ensure consistent firing results, regular maintenance and calibration are required: Calibration (Silver Test):

Users are encouraged to perform periodic temperature checks using an independent system or a silver test to adjust for temperature shifts caused by residue buildup.

The membrane-sealed keypad should be cleaned with a dry or slightly moist cloth; solvents must be avoided. Common Error Codes: Ivoclar Programat P90 Manual

The T-value (target temperature) is lower than the actual temperature in the firing chamber.

Entered B-value (standby temperature) is outside the permissible range of 100°C to 700°C.

The temperature is too high (exceeds target by more than 12°C). Safety Notes Burn Hazard:

Never touch the hot furnace head or reach under it during operation; always use the provided tongs for placing objects in the firing chamber. Electrical Safety:

Do not insert foreign objects or liquids into air vents to avoid electrical shock. Ventilation:

A. Initial Setup & Calibration

The manual stresses that placement is paramount. It requires a solid, vibration-free surface with 10 cm (4 inches) of clearance for ventilation. A dedicated section on "Mains Connection" warns against daisy-chaining power strips due to the unit’s high amperage draw during sintering cycles (up to 1500W).

Part 2: Critical Sections of the Manual – A Closer Look

Creating a Cooling Curve

For zirconia frameworks, the manual allows you to program a long, slow cool (segment 4 or 5). Set rate to 10 °C/min down to 500°C to prevent framework cracking. This reduces residual stresses by 70%.

Part 5: Advanced Features Only Found in the Manual

Most users never venture beyond the "Start" button, but the manual reveals powerful features:

C. Programming Firing Parameters (The "Meat" of the Manual)

This section is written for lab technicians, not casual users. It uses technical shorthand: Ivoclar Programat P90 , introduced in 1987, was

• Start Temp (°C): The temperature at which the furnace lid closes and firing begins.
• Closing Time (min): How long the muffle remains open before closing (crucial for pressing).
• Drying Time (min): Time at low heat to evaporate binding liquid.
• Rate °C/min: The temperature ramp speed (Slow for leucite, Fast for lithium disilicate).
• Final Temp & Hold Time: Peak temperature and duration.
• Vacuum On/Off & Vacuum Level: The manual includes a cross-reference chart showing that pressing requires high vacuum (90%+), while glaze cycles use no vacuum.

Final Score: 9/10

The Ivoclar Programat P90 loses a point only for its dated interface and lack of modern "smart" features (like touchscreen or remote monitoring). However, in terms of its primary function—pressing dental ceramics—it remains a top-tier machine. It is the AK-47 of dental furnaces: it may not look pretty, but it works every single time.

The Ivoclar Programat P90 , launched in 1987, was the first furnace in the Programat line to feature a membrane-sealed keypad. Below is a consolidated guide based on its original operating principles and technical specifications. 🛠️ Technical Specifications Programs: 90 customizable programs. Display: 7-segment display for parameter tracking. Max Temperature: 1200 °C. Voltage: Typically 220V (110-120V versions also existed). Dimensions: Approx. 415 x 433 x 295 mm. Weight: ~16.5 kg. 🚀 Operation Guide 1. Initial Setup IVOCLAR VIVADENT Programat P90 buy on Bimedis

While the specific, complete original manual for the Ivoclar Programat P90 is a vintage document that can be difficult to find as a single download, the following text outlines the standard operating procedures, maintenance, and technical specifications typical of this model based on historical data and similar Programat series furnaces. Ivoclar Programat P90: Quick Reference Guide

The Programat P90 is a classic dental vacuum furnace designed for the firing of various dental ceramic materials. Its reliability is rooted in its straightforward interface and precise temperature control. 1. Control Panel Overview

Numeric Keypad: Used for entering program numbers, temperatures, and hold times. Start/Stop Buttons: Initiates or cancels the firing cycle.

Vacuum Controls: Allows manual or programmed activation of the vacuum pump.

Display Screen: Shows current temperature, program status, and error codes. 2. Basic Operation Steps

Power On: Switch the main power on (usually located at the rear or side). Wait for the furnace to perform its self-test.

Select Program: Enter the specific program number for the ceramic material you are using (e.g., IPS Classic or IPS Design). Start Temp (°C): The temperature at which the

Check Parameters: Verify the following settings on the display: Standby Temperature ( ): Usually around Closing Time ( ): Time taken for the furnace head to close. Heating Rate ( ): Temperature increase per minute. Firing Temperature ( ): The peak temperature for the cycle. Holding Time ( ): Duration the peak temperature is maintained.

Load Material: Place the firing tray with your restoration onto the furnace stage.

Initiate Cycle: Press START. The furnace will automatically close and begin the drying, heating, and vacuum phases. 3. Maintenance & Calibration

Silver Test: It is recommended to perform a silver calibration test periodically to ensure temperature accuracy.

Vacuum Pump: Regularly check the oil level (if applicable) and connections of your vacuum pump to ensure consistent pressure.

Muffle Care: Avoid touching the heating coils and keep the firing chamber clean of debris to prevent contamination of porcelain. 4. Troubleshooting Common Errors

Error E1: Usually indicates a temperature sensor or thermocouple failure.

Error E2: Often relates to the furnace head's movement or a mechanical blockage.

Error E5: Typically a vacuum-related issue; check for leaks in the seal or hose.

Performing a Calibration (Calibration Offset)

If your restorations are coming out over-fired (melted margins) or under-fired (chalky), the thermocouple might drift.

1. Navigate to Service Menu (Press "Stop" + "Temp" simultaneously).
2. Select "Offset."
3. The manual recommends using the Ivoclar Calibration Kit (Ref. 653305AA).
4. Standard offset: If the furnace reads 850°C but the calibration ceramic shows 860°C, enter +10 in the offset menu.
