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
