INSTALLATION AND OWNER'S MANUAL

8. MAINTENANCE

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!)

8.1 Cleaning the pipe system in the heat exchanger

Contamination in the pipes and heat exchanger can reduce the performance of the heat
‰µu‰[• š]š v]µu Z š Æ Z vP ŒX /( šZ]• ]• šZ • U šZ ‰]‰ •Ç•š u v Z š Æ Z vP Œ
must be cleaned by a technician.
Use only pressurized drinking water for cleaning.

8.2 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.

8.3 Winter Shutdown/Lay-up

If there is a chance of frost after the bathing-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.
