0.1 Conformity declaration
0.2 General information
The correct processing of different translucent zirco-
nium dioxides places ever increasing demands on
the dental technician. We help technicians by com-
bining state-of-the-art technology with future-orient-
ed processes in the VARIO S 400 sintering furnace.
The software installed in the VARIO S 400 allows an
individual firing process for all zirconium dioxides
available on the market. The use of top quality
materials prolongs the service life of the furnace
and offers you reproducible results at the highest
level over a period of many years. It is important to
us that you can manufacture top quality dental
prostheses for many years to come with the VARIO
S 400 sintering oven. That's why we inform you of
software updates or additional processing options.
We are sure that you will have much success and
will enjoy working with the sintering furnace, and
we congratulate you on your choice.

0 Introduction
■The VARIO S 400 furnace series was developed
exclusively for the sintering of zirconium dioxi-
des in their different forms (standard, translu-
cent, full contour or dyed) and is intended only
for these applications.
■All other uses require the written consent of
Zubler Gerätebau GmbH.
■The user is liable for any damage resulting from
use other than that intended.
■The manufacturer's warranty conditions apply.
■Use within specifications also includes following
all the instructions in this operating manual.
■The appliance may be operated only by technical
or trained personnel.
■Repairs may be carried out only by authorized
service personal.
■Do not touch the control panel with wet or
moist fingers.
■Please unpack the furnace carefully. It should be
lifted/carried by two people. Always lift at the
base of the unit; never lift the furnace using the
chamber or the table guide.
■Do not actuate the control panel with hard
and/or sharp objects.
■Never operate the furnace without the insulation
base installed on the table.
■Do not reach with your hand between the furna-
ce table and furnace chamber during operation.
There is a danger of being crushed or burned.
■During operation, never reach underneath the
furnace table and never place anything under the
furnace table. The furnace table must not be
blocked during the opening process.
■The cooling slits must not be covered or
obstructed, otherwise the circulation of air is not
guaranteed and the appliance could overheat.
■No liquids or objects may be allowed to enter the
appliance or the vent openings, as it may cause
a short-circuit.
■The furnace table has an electric drive and must
be operated using the buttons on the glass touch
control interface. Do not open or close the furna-
ce table by hand.

Preparation
■Keep the two firing bases at the ready for the
further procedure
Power connection:
■The sintering furnace requires 230 V/50 Hz or
220 V/60 Hz (USA)
1. Do not use extension cables
2. Make sure the unit is plugged into a fuse
protected circuit.
■The main switch should be in the "0" position.
■Circuit breaker for heating in the "ON" position.
■Connect the furnace to the power supply using
the mains cable provided.
■Switch the furnace on at the main switch.
■After the furnace self-test has finished, press the
yellow "Open" button.
0.4 Installing the appliance ■Place the furnace on a stable, even and fireproof
worktop.
■The area surrounding the sintering furnace
should be free 30 cm/12 inches to the right, to
the left, above and behind the appliance.
■Retain the original packaging in case you have to
return the appliance in warranty or for service.
■nsure that the room is well ventilated during

There are a total of six programmable stages. Five
individually programmable heat rates, holding tem-
peratures and holding times. The last stage is
always designated as the cooling stage. The cooling
stage is programmable and does feature an adjusta-
ble cool rate and open temperature.
Programming Stages: Select the number of sta-
ges needed for the program, (Remember the
last stage is always reserved for cooling parame-
ters.)
Example: A three stage program would have 2 sta-
ges of adjustable heat rates, hold temperatures
and hold times, while the 3rd and final stage
would be for the cool rate and open temperature.
The total allowable hold time for an individual
program is 420 minutes. The total individual hold
time allowable for any stage is 300 minutes.
Allowable remaining stage times are automatical-
ly modified as entries are made.
Stage 1 – Stage 1 has a maximum heat rate of
50°C/min, a minimum temperature of 250°C and
a maximum temperature of 1650°C.
Stages 2 to 5: Depending on the desired program,
you can program heat rates or cool rates
between 1 and 100°C/min.
Hold Temperature 2- 5: Depending on the desired
program, you can program temperatures bet-
ween 350°C and 1650°C.
Holding Time 2 to 5: The maximum combined hol-
ding time is 7 hours (420 Min.). Depending on
the desired program and prior hold time entries,
you can program holding times of between 0
and 300 minutes.
Cooling Rate: Cool rate is for cooling down to the
opening temperature. Allowable entry is bet-
ween 1-50°C/min Opening Temperature: The
temperature at which the furnace opens (bet-
ween 250°C and 400°C).
Edit Done?: To save the program use the +/- buttons
or dial to select “Y S” or “NO” and press the

4 Safety warning !
Never place highly combustible materials such as
paper or brushes or highly flammable substances
such as methylated spirits, insulation spray or paint
near the sintering furnace.
■Use this furnace only for its intended purpose as
described in this operating manual and carefully
remove all packaging materials and adhesive
tape during the installation.
■The appliance may be used indoors only.
■Materials that give off toxic gases must not be
sintered.
■Fan openings must not be covered over. Danger
of overheating or safety cut-off of the furnace.
■The appliance may be connected only to a separate
power socket protected by a 16 A slow-blow
fuse with an earth contact and a 30-mA earth
leakage circuit breaker.
■Any interruption in the protective earth conductor
inside and outside the appliance or loosening of
the protective earth connection can lead to the
appliance posing a threat to the operator in the
event of an error. Intentional interruption is not
permissible.
■Position the furnace in a free-standing position. A
free space of 200-300 mm must be maintained
around and above the furnace. Immediately
adjoining walls surrounding the appliance should
be made of a non-flammable material. The area
should be well ventilated.
■In accordance with fire protection regulations,
install a suitable, recommended, multipurpose,
dry-foam fire extinguisher near the furnace and
make sure that your employees have been
instructed how to use it properly.
■Never wear loosely-fitting clothes or clothes that
hang down when operating the furnace. Be
careful when grasping objects in the vicinity of
the furnace. Inflammable material can catch fire
if it comes into contact with a hot surface of the
appliance. The user can sustain severe burns as
a result.
■Do not place the furnace in the immediate vicinity
of sources of heat (e.g. burnout furnaces, ceramic
and press furnaces).
■Make sure that the furnace has been professio-
nally installed in accordance with our instructions
and that the selected electrical connection is
properly grounded.
■Use the grounded appliance power cable I C
C19 for 230/240 V.
■The electrical service must be carefully performed
and must guarantee that the oven is connected
to sufficient voltage. Assign a qualified electrician
to install the proper outlet and voltage supply, so
that you can be sure that the connection is ade-
quate and that no existing circuit is overloaded.
■Do not use an extension cable with the furnace.
Ask your electricity supply company about the
electrical connection values that apply to your
local grid.
■The temperature may rise more slowly if the
voltage is too low.
■Connections should be checked from time to
time to ensure that they are correctly seated and
that they are not worn or damaged. They should
be tightened again or replaced if necessary.
■All cables should be located outside of
passageways and corridors.
■High temperatures can be radiated during operation.
