Thermo Label - Handle
The white thermal part of thermo label becomes black when reaching the specified value.
Note: The thermal part that becomes black once does not return to white. Therefore, if the engine stops and then the
temperature of damper drops, the thermo label continues indicating the maximum temperature while engine is
running.
1. Attach a thermo label to the periphery or front end of damper.
2. Note the maximum temperature to check the thermal part of thermo label when engine stops. Note the temper-
ature periodically, and check the abnormality of temperature alteration.
Note: (a) When the temperature of thermo label increased, identify the abnormality of engine or other cause. Then,
reattach new thermo label, and check the change of temperature.
(b) If the temperature indication of thermo label comes close to the limit temperature of damper or the abnor-
mality is found in change of temperature, contact a dealer of Mitsubishi Heavy Industries, Ltd.
(c) For damper temperature limit and inspection, refer to "Damper - Inspect" (8-4).
