>> Procedures for Replacing Parts
Temperature sensor
The tip of the replaced thermocouple is very important, the location must be the same as shown
in the below diagram. Also inspect and make sure that the tip is in the center of the pipe and not
touching the metal part. This is essential for the sensor to measure the air temperature correctly.
Heater Element
Remove the heater top cap and the heater securing mount to locate the heater element.
Carefully pull the element off the connecting sockets. Replace the broken element with a new
one, make sure that the red colored sealing gasket is installed properly. Installation is just the
reversal. After replacing a new heater element, run the machine at 300
C for at least 10 minutes
to break in the heater before operating at higher temperature.
