By following these recommendations and guidelines, dental laboratories can optimize the performance of the Ivoclar Programat P90 and produce high-quality dental restorations.

Ivoclar Programat P90 is a classic ceramic furnace valued for its reliability in dental laboratories. Maintaining this device according to the Programat P90 Operating Instructions is essential for ensuring precise firing results and extending the life of the heating muffle. Core Components and Setup

The P90 system consists of three main modules that must be correctly connected to function: ivoclar programat p90 manual fixed

Control Unit: Features the keyboard and digital display for managing firing programs.

Furnace Head: Houses the heating muffle (heating element), sealing ring, and thermocouple.

Furnace Base: Contains the power supply connections, vacuum hose recess, and cooling plate. Proper Installation Steps:

Placement: Set the furnace on a flat, fire-proof table, ensuring air vents at the rear remain unobstructed.

Head Mounting: Align the furnace head level with the base and push down until the sealing ring sits evenly on the sealing rim.

Connections: Insert the pump plug into the base socket and connect the vacuum hose to the furnace recess. Troubleshooting Common Error Codes

If your unit displays an error, the following fixes are standard for the P90 model:

Er 1: The firing chamber temperature (T-value) is lower than the actual temperature. This often occurs if the furnace hasn't cooled sufficiently between cycles.

Er 12: Indicates the battery in the control unit is low and needs replacement to save program data.

Er 13: Temperature is too high (exceeding the T-value by more than ). Check for a faulty thermocouple or overheating.

Er 28: Interruption of the heating circuit. This can happen if the furnace is opened manually during a cycle or if the heating circuit fuse (6c) is blown.

Er 90 to Er 97: These typically indicate control unit defects. A common fix is to switch the unit off, leave the furnace open for several minutes, and then restart. Critical Maintenance and Calibration Symptom: The display shows "Heat Up" but the

To keep your furnace "fixed" in top working order, perform these routine tasks:

Sealing Ring Care: Regularly clean the sealing ring and sealing rim with a dry cloth. Debris here is a primary cause of vacuum failure.

Temperature Calibration: Use an ATK2 calibration set to verify firing accuracy. Insert the ATK2 sample into the furnace and run the dedicated calibration program.

Muffle Replacement: If heating performance becomes inadequate or Er 23/Er 24 appears, the heating muffle must be replaced. This involves removing the stone lining segments and spring clips inside the furnace head.

Vacuum Pump: Refer to specific servicing instructions for your pump; ensure the vacuum hose is free of kinks or leaks. Safety Guidelines

Burn Hazard: Never touch the furnace head during operation and always use firing tongs to move objects.

Electrical Safety: Always disconnect the power cord before removing the hood or connection cover for repairs.

Cleaning: Use only a slightly moist cloth; never use solvents or compressed air, as this can distribute ceramic fiber dust.

It seems you are looking for a specific service or repair part for the Ivoclar Programat P90 furnace, likely a "fixed" component (e.g., a fixed heating element, fixed thermocouple, fixed firing tray, or a fixed software part). The phrase “manual fixed piece” is ambiguous, so here are the most likely interpretations and where to find help:

Often, the "manual fix" is simply a power cycle.
