Installation
: Mounting
It is mandatory in any HCC 260/360 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 exchanger.
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.
Faulty installation
The drain hose must never be raised above
the bottom plate!

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.

Correct installation
The drain hose has a correct and steady fall
