Spare parts are supplied only on basis of an order.
If tripping of the thermal fuse Tf1 occurs (due to temperature around the fire damper), the
actuating mechanism including the thermoelectric starting mechanism must be changed.
If tripping of the thermal fuse Tf2 occurs (due to temperature inside the piping), the self-standing
spare part ZBAT72 or ZBAT95, respectively (according to actuating temperature), must be
changed.
