The above-cited safety systems control oven start/stop; in particular:
A. If the oven door is opened while the oven is working the microswitch (F), located centrally
underneath the door aperture, will be tripped.
Pressure on this pin automatically cuts electrical power to the elements, deactivating them.
• The word “Door” and the in-chamber temperature will flash alternately on the display (1).
• re-closure of the door results in restoration of the electricity supply powering the elements.
• real-time in-chamber temperature re-appears on the display (1).
B. The furnace is equipped with a protection system for any overshoot in the temperature
value set.
Up to 550°C: if the temperature setting is exceeded for at last 30 seconds, up to 600°C the
following occurs:
• the words “tEmP” and “OFF” start flashing alternately on the display
.
• an overheating warning buzzer sounds;
• the cycle in progress is automatically cancelled.
Beyond 600°C the setting need only be exceeded by 50°C for at least 30 seconds for the above
to happen.
Pressing CYCLE (5) deactivates the alarm and the word “OFF” appears on the display (1).
It is advisable to run a check on the programmed data.
You can now re-start the interrupted program.
If, of course, the cause of the alarm is not removed the same problem will occur as soon as the
oven is put back in use.
The equipment must not be used with any of its parts disassembled: before
using the equipment make sure that all its components are properly in place.
To ensure that work is done in absolute safety always make sure that you
follow the described procedures with caution.

C. During the second stage temperature increase and during final holding:
- by pressing “+” (8) the display shows the second temperature setting,
- by pressing PROG. (6) the display shows the second stage temperature increase rate.
1. During delayed start (timer countdown).
If there is a power failure during the pre-start phase the timer will recommence its countdown from
the point at which it was interrupted once power has been restored.
2. During temperature increase (both stages).
If there is a power failure while the temperature is increasing the oven will recommence heating once
power has been restored.
3. During the holding time.
If there is a power failure during the temperature holding phase the following occurs:
- if the interruption is only brief and the firing chamber has not had time to cool the oven
recommences the holding phase from the point it had reached at the time of the power failure.
- if, instead, there has been a fall in temperature inside the chamber the oven will, once power is
restored, recommence heating to increase temperature and then restart the holding phase.

RESIDUAL RISK
Residual risk is:
• a danger that cannot be completely eliminated through design and application of safety devices.
• a potential danger which cannot be highlighted.
DE series ovens reach very high temperatures and thus allow specific odontotechny materials to be
fired; the residual risks thus consist of:
• accidental contact (and/or caused by a safety system fault) with the materials or the equipment itself,
during and after the melting phase (risk of serious burns to limbs).
• inhalation of fumes or combustion gas caused by backflow from an incorrectly positioned
aspiration tube.
• work carried out on the equipment interior by unauthorised personnel.
The above-mentioned dangers are indicated by special labels attached to the equipment, as
described in sub-section 3.5.1.
The DE series oven is a equipment that could potentially cause an explosion or
fire where users fails to observe the instructions given in this manual.
Should you have any doubts or queries please do not hesitate to get in touch
with the Manufacturer or an Authorised Servicing Centre.
A beep informs the operator that power has been restored.

equipment.
Eye goggles and a face mask must be worn when using compressed air for
cleaning purposes. Do not allow any persons near the equipment as they could
be hit by flying dust.
Before cleaning the equipment exterior always turn the main switch to OFF. It is
strictly forbidden to clean the equipment while it is connected to the mains
power supply.
Should any of the above anomalies be discovered it is strictly forbidden to
restart the equipment before such faults have been set right.
Never use a naked flame to see what you are doing during checks or maintenance
operations.
More precisely, should the operator note any defects or problems of any kind whatsoever he/she
must place a warning sign on the equipment indicating that maintenance work is in progress and
that using the equipment is forbidden (EC-compliant signs can be purchased from the relevant
suppliers).
Routine maintenance, cleaning and proper equipment use are essential factors in guaranteeing
long-lasting equipment performance and safety.
