3. Remove two M3 nuts and washers in order to detach the thermal switch from the air curtain cover. Do
not lose the nuts and washers: you will need them for reassembly.
Installation
●
When installing the thermal switch, make sure that is tightly fitted to the air curtain cover and that
cables are correctly routed.
CAUTION: Make sure to reconnect the cables to the thermal switch properly: the double-wired O-ring cable
end in one thermal-switch leg and the other single O-ring cable end in the other leg. Otherwise you will
bypass the thermal-switch safeties and risk setting the printer on fire.
