7. To prevent the heat exchanger and the condensate drip tray (Fig. 33/9) from crashing onto the floor, support
them, e.g. with two blocks of wood.(Fig. 33/8).
Loosen the two Phillips screws of the heat exchanger fixing brackets (Fig. 33/7), then carefully lower the heat
exchanger with the condensate drip tray. Pull the heat exchanger and the condensate drip tray towards you
and out of the casing.
Cleaning the heat exchanger
8. Use a commercially available vacuum cleaner or compressed air to remove contamination from the heat
