0.1 Conformity Declaration
0.2 General
The correct processing of modern dental ceramic
materials is placing higher demands on dental techni-
cians. We believe that the VARIO 200 furnaces meet
these requirements by providing the latest technology
for current and future ceramic processing.
The software installed in the VARIO 200 series
enables you to optimize firing management for all
dental ceramics available on the market.
The use of materials of the highest quality increases
the lifetime of the furnace, enabling you to reproduce
optimal results over many years.
Our goal is to ensure that you will be able to produce
top-quality ceramic prosthesis using our VARIO 200
furnaces for many years. We will therefore keep you
informed of any changes to the software or extension
of the processing possibilities.
We hope that the ceramic furnace provides you with
great success and satisfaction. Thank you.
0.3 Setting up the furnace
Connect to pump
Fi ter
Connect to furnace
■Put the furnace onto a stable and level surface.
■Place the vacuum pump near the furnace.
■Please make sure to retain the original cardboard
boxes and other packaging materials. You will need
to have them if returning the device for service.
■Attach the short transparent vacuum hose with
its filter to the connector marked “VACUUM” at
the back of the furnace.
■Attach the long transparent hose to the free end
of the filter.
■Connect the vacuum pump and the furnace
using the vacuum pump power cord.

After the furnace is switched on for the first time
and the firing brick is inserted, run the setup pro-
gram. You are prompted to set the following para-
meters
Main menu ⇒Setup Oven ⇒irst setup program
1. Setting idle temperature
2. Setting night temperature
3. Setting language
4. Setting date and time
5. Setting the unit (° C or ° )
6. Display functions
7. Activate preview mode: "Yes" or "No"
8. After that the furnace will automatically run a dry-
ing program to remove any residual humidity that
might be in the oven after transport or storage
(cycle time approx. 20min).
9. Subsequently, a vacuum test is performed during
which the pump draws vacuum for 2 minutes. After
which a leakage test starts (for another 2 minutes)
to check the seals of the firing chamber.
10. inally, there appears the prompt "Set Vacuum
level." Confirm with "Yes" use the dialer or the plus-
/minus buttons to enter your individual vacuum
level. Always deduct 20mm from the value reached
(e.g: value reached 760mm - 20mm = 740mm indi-
vidual vacuum value).
0.4 Initial oven setup
Start of operation:
■Have the firing tray ready
Electrical connection:
■The ceramic furnace requires 120V/60Hz.
1. Do not use any other power cable or extensi-
on cables
2. Use fused circuit protection before the oven
(e.g. multiway connector at the desk)
■The power switch should be in position "0".
■Connect the furnace to a grounded power outlet
using the supplied power cord.
■Switch on the furnace.
■After a brief self test, the lift will automatically
lower to its maximum open position.
Please immediately insert the firing tray.

■The VARIO 200 furnace series was exclusively
designed for the firing of dental ceramics, and is
intended only for those applications.
■the user shall be liable for damages resulting
from any other use,
■At temperatures above 1075°C/1967° , the working
life of the heating muffle is reduced.
■In case of defect of the furnace, the stated
warranty will apply provided that use conforms
to the specifications within this manual.
■Repairs and maintenance may only be performed
by our authorized Customer Care Center.
■Do not touch the screen with wet fingers.
■Please unpack the oven with caution. It should
always be carried by two persons. Always lift
the device at the bottom, never at the furnace
chamber or table slide bar.
■Never use hard or sharp objects to operate the
touch screen.
■The oven must always have a firing brick on the
lift table.
■During operation, never place your hand between
the lift table and the furnace chamber. There is a
risk of pinching, crushing and a burn hazard.
■During operation never place your hand under
the lift table and do not put any objects under
the lift table.
■Do not block the lift table during the opening
process.
■The air vents must be kept free from obstruction
and clean at all times to allow proper air circulation.
If this is not done, there is a risk of overheating
the furnace.
■Make sure that no liquids or other foreign objects
enter the furnace or the air vents, as this may
result in an electrical shock.
■The lift of the furnace has an electrical lift drive
and has to be operated using the “Open” and
“Close” keys. Do not open or close the lift
manually.

Start temperature Temperature in the
firing chamber at which the program starts.
Pre-dry Selecting “YES” activates the special pre-
drying program.
Pre-dry time Enter a time. In this section, the lift
identifies a predefined position for the entire
time, depending on the heat radiated by the
firing chamber. The object can thus be pre-dried
at a constant temperature.
Closing time Time in which the lift moves in 10
increments into the firing chamber.
Soak temperature At this temperature the object
remains in the closed firing chamber in order to
achieve an even temperature distribution. Soak
temperature = Vacuum start
Soak time States the retention period of the object
in the firing chamber before evacuation and the
temperature increase.
Heat rate Temperature increase per minute
Final temperature Temperature at which the cera-
mic is sintered.
Hold time Period for which the ceramic is maintai-
ned at the final temperature.
Temper Selecting “YES” activates the special tem-
pering program.
Temper temperature Temperature at which the
ceramic is tempered, i.e. subjected to precise
thermal treatment at a constant temperature.
Temper time States the duration of the thermal
treatment in the firing chamber when closed.
Open temperature Temperature at which the devi-
ce opens the firing chamber.
Opening time Decent time of the lift from the
chamber to the fully open position.
Vacuum Selecting “YES” activates the vacuum
parameter (firing under vacuum).
Vacuum release (⇒=Selection)
During the heating up stage ⇒“Release Vacuum
Heat up”
During the hold time at final temperature ⇒
„Release Vacuum Hold time“
During the cooling stage ⇒„Release Vacuum

Vacuum end Displays the temperature or time at
which the vacuum is released.
