Connecting the condensate discharge (CC C)
The units with cooling come standard with a condensate
draining pump. The condensate is drained from the unit
through a flexible hose.
1. Install a sewer connection incl. stink trap for the discharge
of condensate.
2. Connect the discharge hose

to the drain pipe.
In doing so, pay attention to this:
-
For proper condensate discharge, the drain pipe must
be sloping (>2%).
-
Avoid kinks in the discharge hose.
-
Above the ceiling, the discharge hose must be insulated.
