Never open the furnace head by hand; always use the electronic control keys to avoid damaging the motor mechanism.
: The firing chamber temperature (T-value) is lower than the actual temperature. This often occurs if the furnace hasn't cooled sufficiently between cycles.
2. Resolving Heating Failures (Error Code: E1 or No Temperature Rise)
While most labs use the pre-installed programs (P1-P90 for e.max), the manual mode is essential for testing new materials, firing small batches, or troubleshooting. Here is the for fixed manual operation. ivoclar programat p90 manual fixed
: Unlike modern "smart" furnaces that automate drying and closing, the P90 allows the technician to manually adjust and lock in specific closing times and heating rates.
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
To execute manual changes, operators must navigate the classic numeric interface. The standard layout controls primary functions: : Selects custom or pre-set programs. B (Standby Temp) : Modifies idling furnace temperatures. tr (Temp Increase) : Dictates the thermal ramp rate. T (Firing Temp) : Adjusts final heat setpoint. S (Closing Time) : Manages gradual lift head speeds. H (Holding Time) : Controls duration at peak temperature. L (Long Term Cooling) : Regulates the cooling cycle. Never open the furnace head by hand; always
The Ivoclar Programat P90 manual is designed for a wide range of applications in fixed dental prosthetics, including:
Vacuum switch-off temperature is set higher than the peak firing temperature (
is a reliable workhorse, modern Programat furnaces offer significant technological leaps: Programat ceramic furnaces - Ivoclar : Unlike modern "smart" furnaces that automate drying
: Unlike modern touchscreen units, the P90 uses physical buttons and a digital display. Technicians often find this "no-frills" interface easier to navigate for standard cycles. Maintenance
Access the rear or top casing (depending on your specific chassis variation) to locate the thermocouple wires.
The Programat P90’s heating element (muffle) is a fixed, non-user-replaceable part in some senses (requires professional service). If yours is broken, you need:
To ensure optimal results with the Ivoclar Programat P90 manual, follow these step-by-step instructions:
The firing chamber contains ceramic fibers that can release carcinogenic dust. Care must be taken when changing the heating muffle, including using protective gear and avoiding compressed air. Comparison to Modern Models (e.g., P310/P510 G2)
