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 even 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!)
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.
Use only pressurized drinking water for cleaning.
Cleaning the air system
The finned heat exchanger, ventilator and condensate outflow should be cleaned of contaminants
(leaves, twigs, etc.) before each new heating period. These types of contaminants can be manually
removed using compressed air or by flushing with clean water.
It may be necessary to remove the device cover and air inlet grid first.
Attention: Before opening the device, ensure that all circuits are isolated from the power supply.
To prevent the evaporator and the condensate tray from being damaged, do not use hard or sharp
objects for cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and exhaust air
outlet grids. If this happens, the ice must be removed in the vicinity of the air intake and exhaust air
outlet grids to ensure that the minimum air flow rate is maintained.
Winter Shutdown/Lay-up
If there is a chance of frost after the swimming season has ended when the swimming pool heating is
switched off and the external temperature is expected to drop below the operating limit, the water
circuit of the heat pump should be completely drained. Otherwise, suitable constructional measures should
be taken by the customer to protect the heat pump against damage from frost.
Attention: The warranty does not cover damage caused by inadequate lay-up measures during the
winter.
