7. ADVICES - PRECAUTIONS FOR USE
During operation and after use, the surface of the furnace head may become very hot: avoid
direct contact with the skin (risk of burns).
The equipment is equipped with heat extractors to control the temperature of the components
and guarantee safety. Do not cover the furnace during use. Do not place objects on the furnace
or on the ventilation openings.
For avoid screen damage, do not use a sharp object to operate the touchscreen.
Do not open the platform during high temperature cycles: danger of burns and risk of
irreversible damage to heating elements and refractories.
At the end of the cycle, the temperature must be lower than 300°C before opening the
furnace. Do not switch off the power supply, because heat extractors are stopped and the
internal temperature increases and can damage the equipment.
At the end of the cycle, the furnace automatically returns to the standby position. When the
temperature is below 200°C, the power supply can be switched off (switch at the back of
furnace).
When the furnace is in standby, the platform must be in the high position to avoid
condensation.
If the temperature is above 300°C, it is not possible to start a cycle (risk of damaging the
refractories.) Wait for cooling: temperature displayed on the screen below 300°C.
For the first time or after a long time without use, need to preheat the muffle furnace 1 hour
at 120℃ follow 2 hours at 300℃ to eliminate condensation and avoid fractures of the
refractory material.
Molybdenum silicon rods are very brittle at room temperature, do not handle them. Avoid
moving the furnace after installation.
At the start of the cycle, avoid using an increase rate too fast to avoid damaging the heating
elements. Likewise, a large difference between two increase rates is not recommended.
Observe the recommendations of the manufacturer of Zirconia to avoid significant gaseous
emissions which may damage the muffle.
Regularly check the electrical contacts of the heating elements and tighten.
The heating elements must not be maintained for long periods between 400°C and 700°C to
avoid their oxidation.
Place the support on the platform while the furnace is working. Use only the original support
e.ON SINTER – UGIN DENTAIRE. Before use, check support: no dirt or damage. If necessary
clean with a brush (see chapter 8 - maintenance), if damage or crack: do not use and replace-it.
Wear suitable gloves when handling support, tray/cover and the prosthetic objects: hot
surfaces - risk of burns.
