It is mandatory in any HCC 2 installation to connect a water drain hose to the unit, because
the humidity from the extract air condensates to water drops when cooled in the heat ex-
changer.
This water is harmful to its surrounding if not managed correctly. The installation thus needs a
condensate water drain hose connected with a decline of minimum 10 Promille (1 cm/meter)
away from the unit and the hose must NEVER exceed the level of the lower sheet metal plate.
Correct installation
Faulty installation
After guiding the hose downwards to a drain, it needs a closing loop. This will block air from
escaping through the hose. Please make either a complete closed loop, or a siphon loop on
the hose as illustrated, and make sure it has a minimum height of 100 mm. Fill the siphon/
loop with min. 0,5 l. water before connecting the hose to the unit.
The drain hose has a correct and steady fall
towards the sewer.
The drain hose must never be raised above
the bottom plate!
