Drain and hose must be checked every year.
Check that the hose is secured properly to the unit, and that there is water in the water trap.
Check that the hose is not wrinkled and that there is a minimum gradient of 1% from the unit
to the drain. If the hose is routed to different surrounding temperatures, make sure the hose
is protected against frost damages.
Ensure that the condensate drain is not blocked in the drip tray. Clean the drip tray with
soapy water and a brush or cloth every other year, to ensure good hygiene inside the unit.
Please follow this procedure to clean the drip tray:
