6 Servicing
6.2 Cleaning the Heat Exchanger
IMPORTANT: When removing and replacing the heat
exchanger take care not to damage it.
Take care not to damage the heat exchanger fins. Any
damage will lead to premature wear in the system.
Refer to section 4.5 and open the unit and remove the filters
then the front panel.
Hold the heat exchanger with both hands at the edges
and without damaging the fins, carefully pull out the heat
exchanger, see diagram 6.2.
Clean the heat exchanger with a washing liquid with neutral
pH and lukewarm water, then rinse it again with clear
lukewarm water.
NOTE: detergents, especially acidic detergents (such as
vinegar cleaner), damage the unit.
The heat exchanger must be dry before replacement.
With the removed heat exchanger check as well if the
condensate water drain is clean, if necessary clean as
described below.
Slide the heat exchanger back into the unit. Take care that
the heat exchanger correctly fits into the guide rails at the
top and bottom of the housing and that it is not installed off
centre.
IMPORTANT: The heat exchanger must be flush with the
front side of the EPP body. A protruding heat exchanger can
cause leakages and condensate escape.
6.3 Cleaning the Condensate Drain
With the heat exchanger removed.
Unscrew the condensate drain trap from the bottom of the
unit, see diagram 4.2.
Check if the drain is free, see diagram 6.3.
Clean it if is blocked.
If required, clean any dirt in the drain pan.
Clean the condensate drain trap and fill it with clean water.
6.4 Cleaning or Replacing the Bypass
Filter
Bypass, if fitted.
See diagram 6.3 for the location of the bypass filter.
If the filter is not heavily soiled, you may clean it with a
normal vacuum cleaner.
If this is not enough, the filter must be replaced.
Cleaning the filter with water or other liquids is expressly
prohibited.
6.5 Test Operation and Restart
After servicing check the correct functioning of the unit:
•
Check that the unit casing is correctly fitted.
•
Insert the mains plug into the plug socket and start the
unit.
•
Check the correct function of the unit.
•
Check the correct function of the remote control.
