Unsupervised operation
The device may be operated unsupervised, provided the national and
local laws and provisions allow for such action and provided that they are
observed. Furthermore, the requirements of the respective insurance
company must be met.
– Never use the device if the work environment is heavily soiled.
– Protect the device against unauthorized access.
Safety notes
This device has been designed according to EN 61010-1 and has been
shipped from the manufacturer in excellent condition as far as safety
regulations are concerned. To maintain this condition and to ensure risk-
free operation, the user must observe the notes and warnings contained
in these Operating Instructions.
– The user must especially become familiar with the warnings and
operating conditions to prevent injury to personnel or damage to
materials. The manufacturer is not responsible for damage resulting
from misuse or failure to observe the Operating Instructions. Warranty
claims cannot be accepted in such cases.
– Before switching on the furnace, make sure that the voltage indicated
on the rating plate complies with your local power supply.
– The mains socket must be equipped with a residual current operated
device (FI).
– The power plug acts as a circuit breaker and may only be connected
with an easy-to-access power socket with protective contact.
– Use only the power cord supplied with the furnace or a power cord with
the same specifications.
– Place the furnace on a fire-proof table. Observe local regulations,
(e.g. distance to combustible substances or objects, etc.).
– Always keep the air vents on the sides and at the rear of the furnace
free from obstruction.
– Do not touch any parts that become hot during operation of the
furnace. Burn hazard!
– When removing hot components from the firing chamber (e.g. firing
table, firing tray), make sure to place them on a fire-proof surface.
– Clean the furnace only with a dry, soft cloth. Do not use any solvents!
Disconnect power before cleaning and allow the furnace to cool down!
– The furnace must be cool before it is packed for transportation.
– Before calibration, maintenance, repair or change of parts, the power
must be disconnected and the furnace must be cool if it needs to be
opened.
– If calibration, maintenance or repair has to be carried out with the
power connected and furnace open, only qualified personnel who are
familiar with the risks and dangers may perform the procedures
(certified Service Centre).
– After maintenance, the required safety tests (high voltage resistance,
protective conductor, etc.) must be carried out.
– Make sure that only fuses of the indicated type and rated current are
used.
– Use only original spare parts.
– If it is assumed that safe operation is no longer possible, the power
must be disconnected to avoid accidental operation.
– If the furnace is visibly damaged, the power must be disconnected to
avoid accidental operation.
– Check the correct function of the device after storage under
unfavourable conditions over an extended period of time.
– If the furnace does not work properly, the power must be disconnected
to avoid accidental operation.
– The temperature range for faultless operation is +5 °C to + 40 °C
(41 °F to 104 °F).
– If the furnace has been stored at very low temperatures or high
atmospheric humidity, it must be left to dry or to adjust to room
temperature for approx.
4 hours before it is operated (do not connect the power yet).
– The furnace is tested for use at altitudes of up to 2000 m above sea
level.
– The furnace may only be used indoors.
– Before leaving the factory, the furnace functions were tested for
several hours. It is therefore possible that these tests have caused slight
discolouration of the insulation. Nevertheless, your Programat is still a
brand new furnace.
