NEW EcoHeater

DSEH200301.01.EN

Continuous product development may give rise to specification changes without notice.

6.6 Sound attenuator (code EMT-02)

The purpose of the sound attenuator is to reduce the sound power level in the

system.

Inspection

Check that the baffle elements are intact and have clean surfaces. Take action if

necessary.

Cleaning

Vacuum and/or wipe all surfaces with a damp cloth. In the event of heavier soil-

ing, rotating nylon brushes can be used.
