WARNING
Risk of burns due to hot surfaces!
Hot surfaces arise at some points on the inLab Profire high-
temperature furnace. Use the necessary caution around the furnace,
especially when the furnace is operated for extended periods.
➢ Do not reach into the casing or the furnace door during operation.
➢ Do not reach into the heating chamber. It may still contain
residual heat from a preceding heating operation.
➢ First allow the furnace to cool down before maintenance,
cleaning, and repair work.
➢ Wear heat-resistant safety gloves if work on hot components is
necessary.
➢ Use suitable and sufficiently long removal tongs to remove and
adjust the sinter.
WARNING
Risk of burns due to hot surfaces!
Once the program has ended and the furnace has shut down, the
cooling fan will run until the interior temperature of the furnace has
been reduced to normal. The power plug may not be disconnected
prior to this point.
CAUTION
Handling the insulation material
The combustion chamber contains ceramic mineral fibers as
insulating material (index No. 650-017-00-08), which are presumably
classified as carcinogenic CAT 1B (Annex VI, EC 1272/2008). When
working on the combustion chamber or replacing the door insulation,
fiber dust can be released. The dust pollution can possibly be
carcinogenic when inhaled as well as cause irritations to the skin,
eyes and respiratory organs.
When replacing parts of the insulation, proceed as follows:
- Wear long-sleeved protective clothing
- protective glasses, FFP 2 respiratory mask and protective gloves
- Only use a vacuum cleaner with a fine particle filter (HEPA dust
class H)
Abrasion of insulating material in the furnace door area may occur,
which is visible as white dust. These deposits should:
- be wiped off with a moist cloth or
- be extracted with a vacuum cleaner with a fine particle filter (HEPA
Dust category H),
- not be blown away with compressed air
First aid measures
➢ After inhalation: In the case of irritation, move yourself into a dust-
free zone, drink some water and blow your nose. If the symptoms
persist, please seek medical advice.
➢ After skin contact: In the case of contact with skin, immediately
wash off with plenty of water and soap.
➢ After eye contact: Immediately rinse with an eye wash in a careful
and thorough manner using plenty of water. Do not rub your eyes!

IMPORTANT
Always dispose of the insulating material in a closed container (see
also the section on "Disposal").
WARNING
Risk of burns due to objects falling out
As there is a serious risk of burns in this case, it is essential to install
a fire-proof table and floor covering.
I. For safety reasons, the furnace must be operated when standing.
This is the only way that the user can quickly avoid any parts that fall
out.
II. The operator of the site is responsible for providing the user with
appropriate safety instructions.
III. If a fracture occurs during the sintering process as a result of a
failure to adhere to the recommended drying procedure, there is a risk
that hot objects will fall out as soon as the furnace door is opened.
IV. The furnace should only be loaded and unloaded using the
crucible fork. For safety reasons, a trained user must be present
when the furnace is being loaded or unloaded.

3Technical description
3.1 Description of the furnace
The inLab Profire high-temperature furnace is used for processing
sinterable ceramics and cobalt-chromium.
The product to be sintered is placed in the sintering tray and positioned
on the bearing plate. After entering the heating parameters and
pressing the start symbol, the electrically powered furnace door closes
and the heating operation begins.
Once the heating program has been performed and the furnace has
cooled down, the furnace door opens and the finished product can be
removed.
Heating chamber
The product is sintered in the heating chamber.
It consists of two different ceramic insulating layers and is operated
using MoSi2 heating elements.
The outer insulating layer is designed for temperatures up to 1,200°C;
the inner one for temperatures up to 1,700°C.
Furnace door
The furnace door consists of a ceramic door panel.
A slip clutch used in the drive mechanism prevents an excessively high
contact pressure between the furnace door and the heating chamber.
Furnace casing
The furnace casing consists of a steel plate and is plastic-coated on the
inside and outside.
Program controller
The program control system is fitted with a timer function based on
week day and time.
Operating parameters and heating programs are stored in a nonvolatile
memory and are retained even if there is a power failure.
The configured setpoint temperature is kept with a precision of ± 1°C. A
temperature sensor integrated into the heating chamber detects the
chamber temperature near the product.
The furnace is prevented from overheating due to a defective
temperature sensor using a thermocouple break protection.
