Cleaning the plate heat exchangers
Dirty plate heat exchangers can cause inefficient operation and
a high noise level. If they are dirty, clean the exchangers.

• Via the side.
• Via the underside.
Warning:

Set the isolation switch to 0.
1. Open the side shield

Note:

Preferably, also open the side shield if you extract
the exchangers via the underside. This will ensure
that the exchangers are no longer clamped fast.
2. Open the two inspection hatches of the heat exchanger
module that are located next to the recirculation module
