THERMOCOUPLE REPLACEMENT
Disconnecting and reconnecting the thermocouple causes an error and resets the furnace and
all programs.
-
Disconnect
the furnace from the main power supply (switch OFF and unplug to mains socket).
-
If necessary,
wait the cooling
at room temperature before to replace.
-
Unscrew the
thermocouple cover
(No. 4).
-
Unscrew the thermocouple
and disconnect the two wires attached to it.
-
Place the new thermocouple
and re-connect the two wires, making sure to hook up the wires correctly
(respect the polarity):
+ : green wire / - : white wire.
NOTE: the negative wire (white) is slightly magnetic.
-
After replacing the thermocouple,
press the P key
to remove the faulty probe on the furnace. This also
resets the programs settings.
-
Let the furnace
heat up at a steady 200°C
to check if is working properly. It is then ready for use again.

MUFFLE REPLACEMENT
IMPORTANT
–
Personal Protective Equipment
PROGRAMIX 50 / 100 contains insulating material composed of high temperature insulation wool
(alkaline earth silicate), a substance not classified as dangerous according to Regulation 1272/2008/EC
(CLP).
The muffle replacement requires contact with the heating chamber and the insulation plates. The
personnel involved must be equipped with the appropriate
personal protective equipment
.
It is recommended to wear respiratory protection (mask type FPP2), protective coverall, gloves and
goggles. For cleaning, use a vacuum cleaner - do not use a broom and/or compressed air.
-
Disconnect
the furnace from the main power supply (switch OFF and unplug to mains socket).
-
If necessary,
wait the cooling
at room temperature before to replace.
-
Dismounting the thermocouple
: unscrew the thermocouple cover, the thermocouple and disconnect the
two wires attached to it.
-
Unscrew the rear panel.
-
Remove the insulation plates.
-
Disconnect the muffle connections.
-
Take the insulation wool
off the upper half.
-
Get the muffle out
, from the rear.
-
Install the new muffle
, taking care to keep the resistor terminal at least 5 cm away from heating element.
-
Reassemble the various components
by reversing the dismounting order.
Warning: during the placement of thermocouple, respect the polarity (re-connect the wires correctly:
+ : green wire / - : white wire
) (see chapter 9.3).
-
Dehydrate the furnace
by heating it up at
200°C for 1 hour
. It is then ready for use again.
