Thank you for choosing the Zubler VARIO 200
Ceramic Oven. We hope you are pleased with the
improvements and new features. Be assurred, our
technology comes from the requirments of experi-
enced dental technicians and our desire to continu-
ally improve the performace of our products for our
clients.We focus on the goal of building furnaces of
the highest quality, flexibility and sustainability.
Performance and efficiency are a basic requirement.
Although easy operation is ensured, we encourage
you toread the manual carefully.

hereby declare, that the ceramic furnace product
VARIO 200
is in compliance with the protective requirements in
accordance with the provisions of the following
directives:
2006/42/EG Machines Directive
2006/95/EG Low-Voltage Directive
2004/108/EG EMV Directive.
In the event of any amendments being made to the

Managing Director
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.

in use.
The “night mode” program is started by pressing
the green “Enter” key. If you start the “night
mode” program and the oven is open, the oven
cools down to the programmed temperature and
closes automatically. The program is ended by pres-
sing “abort”.
1.5.1 Stand-by temperature
To save energy and prevent impujriteis or con-
densation inside the furnace, we advise you to
keep the firing chamber closed when it is not
being used.
Should you be prevented from closing the furnace
yourself, stand-by is automatically activated 30
minutes after a program has finished and the oven
is not closed.
If the oven is closed after the last firing, the idle
temperature is kept for 4 hours. After 4 hours the
oven automatically starts the “stand-by” mode.
■irst you hear an acoustic signal
■The temperature in the firing chamber is lowe-
red to the 100°C stand-by temperature.
■Once stand-by temperature has been reached,
the lift closes and remains in a closed position.
■After touching one of the pads, the oven goes
back to idle temperature.
■The stand-by temperature is a fixed temperature
and cannot be changed.

2.5 Operational Information
The operator using the furnace must close the
lift after completing a firing program
After closing the lift, the unit will remain at the pro-
grammed idle temperature for four hours. If the unit
is not used, it will automatically go into the “stand-
by” mode.
If, at the end of the program, the chamber is not
manually closed, the device will automatically cool
down to the safety temperature of 400°C, indepen-
dent of the idle temperature selected. Once this
temperature has been reached, the device will
remain in this state for 30 minutes.
At the end of this time, the device will enter stand-
by mode and close automatically after the defined
stand-by temperature of 100°C has been reached.
Duplicate program names are not allowed.
Overwriting a program during operation
(see 1.1 Run Programs)
1. Should you find that you have to temporarily
change one or more parameters while a program is
running, you can do this by pressing the yellow
“Edit Prog.” key below the display.
2. In general, you can only change parameters that
have not already been started when you press the
yellow “Edit Prog.” key.
3. The changes you have made are temporary and
apply only to the current firing cycle.
4. Editing can be carried out only once during the
firing cycle.
