Cleaning the
inside of the unit
Annual cleaning is recommended at the least, depending on the
degree of soiling of the heat exchanger.
Rinse the heat exchanger with warm water and conventional
cleaning agents (soap suds).
Never clean the heat exchanger with compressed air, steam jets or
high pressure cleaners. It may be ruined!
Annual cleaning is recommended at the least, depending on the
degree of
soiling of the unit.
The battery blades may not be damaged during cleaning.
Use a vacuum cleaner or a soft brush to remove dust.
An irreparable defect in the pre- or re-heating battery shall
require replacement
with an original heating battery.
Check the plates for free movement.
Use a soft brush and soap
suds to clean the plates.
Do not oil the plates, since the
plastics used may be destroyed,
impairing their functionality.
Regularly check the condensate tray for soiling.
Depending on the degree of soiling and the temperatures, it
is recommended to clean the condensate drainage,
drainage line and siphon at least once a year.
The siphon must be filled with water before switching the
plant on again.
Annual cleaning at least of the inside of the unit housing is
recommended, depending on the degree of dirt.
Handle the housing surfaces with care during cleaning.
Use a vacuum cleaner to remove dust.
Electrical components may not be exposed to moisture or wet
conditions. Be particularly careful not to damage the electrical
wiring.
