Make sure that the condensate drain is not clogged in the drip tray and clean the drip
tray with soapy water and a brush or a cloth every second year to ensure good hygiene
inside the unit.
The unit must be kept clean to ensure error free operation and good hygiene.
Internal cleaning are only necessary if the unit is open e.g. in connection with service.
Check the internal surface in the unit. If it is dirty, clean with a wet cloth, brush, vacuum
cleaner or the like.
Drain, external connections and hose installations must be checked once a year before
the risk of frost occurs.
Make sure that the hose is firmly connected to the unit and that the water trap is filled
with water.
Make sure that the hose is not broken and that the hose drops minimum 1% toward the
drain, and that the hose is protected against frost from unit to drain.
Check the heat exchanger for dirt every second year.
Clean the heat exchanger with a soft brush and a vacuum cleaner at all four inlets,
In special cases, e.g. if there are clear traces of accumulated, dirty condensate water in
the heat exchanger, it is necessary to remove the heat exchanger from the unit and
clean the exchanger with soapy water.
The controller must only be checked if an error occurs on the unit.
Make sure that all connections are all right and that the controller is clean and free with
out dust or moisture.
