condition as far as safety
regulations are concerned. To
maintain this condition and to
assure risk-free operation, the
user must observe the notes and
warnings contained in these
Operating Instructions.
– Do not place furnace and
pump in the immediate
vicinity of heaters or other
sources of heat.
– The furnace must neither be
placed nor operated in areas
where there is an explosion
hazard.
– Place furnace on a fire-proof
table (observe local regulations,
e.g. distance to combustible
substances or objects, etc.)
– Always keep the air vents at
the rear and the side of the
furnace free from obstruction.
– Position vacuum pump in a
well ventilated place. Make
sure that no foreign objects
enter the furnace base.
– Do not place any objects on
the housing. Use the cooling
plate for this purpose.
– Keep sealing ring of the
furnace head and sealing rim
of the furnace base clean and
avoid damage.
– Do not touch any parts
that become hot during the
operation of the furnace.
There is a burn hazard!
– Clean furnace only with a dry
or slightly moist cloth. Do not
use any solvents! Disconnect
power before cleaning.
– Use original packaging for
transportation purposes.
– The user must especially

– If calibration, maintenance, or
repair has to be carried out
with the power connected
and the furnace open, only
qualified personnel, who are
familiar with the risks and
dangers, may perform these
procedures.
– After maintenance, the
required safety tests (high
voltage resistance, protective
conductor, etc.) have to be
carried out.
– Ensure that only fuses of the
indicated type and rated
current are used.
– If it is assumed that safe
operation is no longer
possible, the power must
be disconnected to avoid
accidental operation.
Safe operation is no longer
possible if
– the furnace is visibly
damaged
– the furnace does not work
– the furnace has been stored
under unfavourable
conditions over an extended
period of time
– Maintenance work and
changing of the heating
muffle may only be carried
out by qualified personnel.
– Use only original spare parts.
– The temperature range for
faultless operation is +5 °C to
+35 °C (+41 °F to +95 °F).
– If the furnace has been stored
at very low temperatures or
high atmospheric humidity
the head has to be opened
and the unit dried or left to
adjust to room temperature
for approx. 1 hour (do not
connect the power yet).

loosening of the protective
conductor connection may lead
to danger for the user in case
of malfunction. Deliberate
interruptions are not tolerated.
Materials developing harmful
gases must not be fired.
Do not place any flammable
liquids or objects in the vicinity
of the furnace. Observe the
necessary safety distance to the
