5. Maintenance

5.1

Replacing the anode

The anode has to be replaced when the alarm no. 9 is presented in the
display. The anode (7) is situated behind the front cover. Before the anode is
replaced the storage has to be emptied. This is made by turning off the cold
water supply and then open the drain valve (on the cold water inlet). At the
same time the hotwater tap has to be turned on to avoid negative pressure
inside the tank.
5.2

Maintenance of the evaporator

Once or twice a year the evaporator should be examined and cleaned
if necessary. To reach the evaporator the air inlet/outlet ducts has to
be removed. If not cleaned the heat pump capacity will decrease. The
evaporator is preferably cleaned with water and a brush. Avoid any water
on electrical parts! The evaporator fins must not be damaged. The intervals
needed for cleaning is depending on the air quality. If the air used for the
heat pump contains a lot of particles, a more frequent cleaning may be
necessary.
Maintenance of the drain
The condensation water outlet must be connected to a drain in accordance
with the present regulations. The defrost/condensed water outlet of the
heat pump must always be kept free from dirt. How frequent this has to
be done depends on the local conditions concerning dirt, humidity and air
temperature. A blocked outlet causes the defrost/condensed water tray to
flood and the fault circuit breaker may cut if electrical parts are exposed to
water.
The warranty does not cover damages caused by lack of maintenance.
