- Otherwise if the filter is inside the intake grid, remove the grid and carry out the
operations described below.
FIGURE 12:
-1- MA/F - MA/FO = Intake modules with filter
-2- The air filter, secured to the intake module by means of screws, is pulled out like
a drawer.
Clean the filter with lukewarm water or, for dry powders, with compressed air.
Reinsert the filter after having let it dry.
CLEANING OF THE HEAT EXCHANGER
It is advisable to check the condition of the heat exchanger before the onset of the
summer season, checking that the fins are not clogged by impurities. To access the
heat exchanger, remove the delivery panel (whether it is the collar or rectangular flange
type) and the condensate tank. Upon having accessed the heat exchanger, clean
with compressed air or low pressure steam, without damaging the fins of the heat
exchanger.
Before operating it in the summer, check that the condensate discharges regularly.
Adequate and regular maintenance means energy conservation and cost
