8. MAINTENANCE THE UNIT
To protect the paintwork, avoid leaning or putting objects on the device. External
heat pump parts can be wiped with a damp cloth and domestic cleaner. (Attention:
Never use cleaning agents containing sand, soda, acid or chloride as these can
damage the surfaces.)
To prevent faults due to sediments in the titanium heat exchanger of the heat
pump, ensure that the heat exchanger cannot be contaminated (water treatment
and filter system necessary). In the event that operating malfunctions due to
contamination still occur, the system should be cleaned as described below.
(Warning: the fins on the finned tube heat exchanger are sharp-edged -- danger of
being cut!)
8.1 Cleaning the pipe system in the heat exchanger
Contamination in the pipes and heat exchanger can reduce the performance of the
heat pump’s titanium heat exchanger. If this is the case, the pipe system and heat
exchanger must be cleaned by a technician.
