INSPECT FINS FOR BLOCKAGE

If fins are clogged, wash them with water or a steam cleaner and dry with compressed air.

NOTE:

If the distance between the steam cleaner and the core is too close, there is a possibility of damaging the fin, so keep the following injection distance.

If the fins are bent, straighten them with a screwdriver or pliers.
Never apply water directly onto the electronic components.
