the respective preceding value is changed).
MaIntenance/care
_ Wipe the upper surface of the furnace with a
moist cloth when necessary. In no event must
water enter the inside of the chamber! Do not
clean with organic solvents.
_ Regular maintenance/calibration of the heating
elements and insulation is not necessary. A
visual check of the heating elements before
starting the sintering program is recommended!
exchanging the heating elements
_ If the indicator lamp of the heating
@
shines
continuously after the start-up of the sintering
program, this means that the heating element
has failed.
_ If one heating element fails, always replace
all 3 elements! If a heating element should fail
again, the heating elements already used can
be fitted again.
general instructions
_ During the installation of the heating elements
in the furnace, a small amount of refractory
material may adhere to the heating elements;
this is harmless and will vitrify during the first
few sintering processes.
_ Lamp test: in case not all of the two LEDs

are defective; please contact the customer
service.

recommended to occasionally run a sintering
programme with empty furnace.
_ Each furnace runs through one programme
