3. Safety
The FINOSINT KOMPAKT High-Temperature Sinter Furnace High-Temperature Sinter Furnace is a high-
temperature oven for commercial use in dental laboratories and may be used only for sintering sinterable
ceramics.
3.1 Requirements for personnel
Trained and qualified personnel who know how to use the unit and whose specialist training, skills, experi-
ence and knowledge of the relevant regulations enables them to carry out the tasks assigned to them inde-
pendently and recognise and avoid potential hazards.
DANGER
Electricity
!
Risk of death from electric shock.
➤ Do not touch live cables and components with wet hands.
➤ Observe the accident-prevention regulations when working with electric cur-
rent.
➤ Before carrying out any installation, maintenance, cleaning or repair work,
disconnect the power supply of the sintering oven (pull out mains plug) and
secure it against being switched back on.
DANGER
Risk of ignition!
Use of inflammable and explosive materials near the oven.
➤ Do not operate the sintering oven near highly inflammable sources.

WARNI
NG
Risk of burns from hot surfaces!
The surfaces of the sintering oven become hot during operation.
These may cause burns if touched.
➤ Do not touch the housing or the oven door during operation.
➤ Do not reach into the heating chamber. It may still retain a high level of resi-
dual heat from the previous heating process.
➤ Ensure that the sintering oven has cooled down before carrying out mainte-
nance, cleaning and repair work.
➤ Wear heat-resistant safety gloves if it is necessary to carry out work on hot
components.
➤ Use a suitable and sufficiently long pair of tongs to place items to be sintered
into the oven and remove sintered items from the oven.

CAU ION
Incorrect operation!
No liability is assumed for damage that may be caused by misuse, incorrect
operation, incorrect connections or improper maintenance/repair work carried out
by untrained personnel. All warranty services are also excluded in such cases.
The unit must not be used if it or the mains cable becomes damaged and no
longer functions correctly. In this case contact the manufacturer immediately.
For your own safety and to increase the service life of your unit, use only original
replacement parts.
To ensure safe operation of the sintering oven, regional regulations (e.g. acci-
dent-prevention regulations) apply in addition to the instructions in this operating
manual. The former must be made available by the operator of the unit. The
safety notices on the sintering ovenmust be kept in a legible condition.
NO ICE
This operating manual must be read and understood by each user before working
on and with the unit.
The operating manual must be kept for the specified service life of the sintering
oven.

4. echnical description
4.1 Function
The FINOSINT KOMPAKT High-Temperature Sinter Furnace is used to fire sinterable ceramics.
The product to be sintered is placed in the sintering dish and set on the support pins in the combustion
chamber.The heat-up process starts after entering the heating parameters and pressing the Start button.
Once the heating program has ended and the sintering oven has cooled down, the finished product can be
removed from the oven.
Heating chamber
The product is sintered in the heating chamber. This consists of two different ceramic insulation layers and is
operated using four heating elements connected in series. The outer insulating layer is designed for tempera-
tures up to 12 °C; the inner layer for temperatures up to 165 °C.
Oven door
The oven door consists of a two-part ceramic door panel. A safety switch disconnects the heating current as
soon as the oven door is opened.
The oven door has an electronic lock and can be opened only if the temperature is below 3 °C.
Oven housing
The oven housing consists of steel plate coated with plastic on both the inside and the outside and is cooled
by a permanent ventilation system.
NO ICE
The packaging protects the sintering oven against transport damage, corrosion
and other forms of damage. Only remove it shortly before initial commissioning
and store it in dry conditions for later reuse.
NO ICE
emperature damage!
To prevent temperature damage:
➤ Store the unit only at temperatures between +5 and +4 °C.
➤ Always store the unit in dry and dust-free conditions.
➤ Avoid exposure to direct sunlight.
➤ Avoid mechanical vibrations.

ENG
Program controller
The program controller has a finishing-time setting that can be used to specify a day and time for the program
to finish. The switch-on time is calculated automatically so that the heating process is stopped at the required
time and the sintered item can be removed.
Operating parameters and heating programs are stored in a non-volatile memory and are retained even if the
power supply fails.
The set target temperature is maintained within an accuracy of ± 1 °C. A temperature sensor integrated into
the heating chamber measures the temperature of the chamber close to the product.
A thermocouple fail-safe prevents the sintering oven from overheating if the temperature sensor becomes
defective.
4.2 Intended use
The FINOSINT KOMPAKT High-Temperature Sinter Furnace is a high-temperature oven for commercial
application in dental laboratories and may be used only for sintering sinterable ceramics using original spare
parts.
At a total output >1kW, no limit values for the harmonics apply.
4.3 Potential misuse
•Operation by untrained and insufficiently qualified personnel.
•Use of products that have not been approved by the manufacturer.
•Use of replacement parts that have not been approved by the manufacturer.
•Any use not in accordance with the declaration of conformity.
•Technical modifications to and conversions of the unit that have not been approved by the manufacturer.
NO ICE
The protection of persons can no longer be ensured and no liability can be assu-
med for damage that is caused by misuse, incorrect operation, incorrect connec-
tions or improper maintenance/repair work carried out by untrained personnel. All
warranty services are also excluded in such cases.
The use of spare and wearing parts that have not been procured from the manu-
facturer will render the approval and guarantee of the sintering oven null and
void.

6. Installation
6.1 Installation location
The FINOSINT KOMPAKT High-Temperature Sinter Furnace is designed as a table-top unit. To ensure
stability, we recommend a level surface of at least 5 cm x 6 cm that can support a load of up to 6 kg.
Installation conditions
➤ Always install the sintering oven in dry rooms that are as dust-free as possible and make sure that liquids
cannot penetrate the unit.
➤ Highly inflammable and combustible gases and liquids must not be stored in the installation rooms.
➤ Do not place any combustible and inflammable objects near the sintering oven.
➤ Keep a distance of 5 mm around the sintering oven for sufficient cooling.
1. Align the supporting surface horizontally.
Lift and carry the sintering oven only at the unit base.
2. Place the sintering oven on the supporting surface.
Make sure the surface is non-slip.
CAU ION
ipping loads!
Supporting surface with an insufficient load-bearing capacity.
➤ When installing the sintering oven, make sure that the supporting surface has
a sufficient load-bearing capacity.
CAU ION
Risk of injury due to oven weight!
Physical strain/back injuries due to the high inherent weight.
➤ Have at least two persons carry/move the sintering oven together (max. 3 kg
load bearing capacity/person).
CAU ION
Risk of overheating!
In the event of overheating, the electronic system will switch the heater off.
➤ Make sure that the air vents remain clear on all sides.

Electrical connection
7.2 Local installation
The sintering oven requires its own electrical circuit.
The building's electrical circuit must have a type-K or type-Z circuit breaker with a rated current of at least
16 A (other types of circuit breaker depending on the country of use).
An additional residual-current circuit breaker (designed for 3 mA tripping current) must be installed.
To ensure electrically safe operation, the sintering oven requires a protective earth conductor connected
to the power socket.
When selecting the installation location, ensure that the accompanying mains cable is 2. m long. Ex-
tending the cable is not permitted. The supply voltage must be within the rated voltage range of 2 - 24
V (see section „Technical Data“).
WARNI
NG
Release of pollutants!
Pollutants can be inhaled when the insulating materials are handled.
➤ Wear personal protective equipment (respiratory protection) during disposal.
DANGER
Electricity
!
Risk of death from electric shock.
➤ Do not touch live cables and components with wet hands.

rent.
➤ Only connect the unit to a voltage supply that matches the specifications on
the rating plate.
