brackets.
f VRL-C 6 25, VRL-C 870: Undo the screws on the heat exchang- f
er mounting bracket.
f To install the heat exchanger with the same orientation at a f
later time, mark the installation position of the heat exchang-
er before removing it.
f Carefully remove the heat exchanger from the unit. Do not let f
it fall.
f Use a commercially available vacuum cleaner to remove dust f
and other loose dirt particles from the intake and discharge
surfaces.
