Checking and cleaning condensate drain

Note the instructions for cleaning the heat exchanger and ventilation unit!

  1. Wash out the condensate tank. The condensate pump can only be checked with the unit running. To do this, fill the condensate tank with water and check whether the pump extracts this when the unit is switched on.*

CAUTION! Risk of injury due to fans starting up. Do not reach into the fan. Ensure that the heat exchanger is not bent or damaged when pulling out.

* Only for version with cross-counterflow heat exchanger (variant G).
