6.3.8 Rotary heat exchanger
WARNING!
Risk of injury from rotating parts!
Incorrect handling, e.g. reaching into rotating parts,
can lead to serious injuries.
Never reach into or tamper with the storage mass
–
Switch off the system before you start working on
movable parts of the rotary heat exchanger and
secure it against accidentally being switched on
again. Wait until all parts have come to a stand-
still.
–
Do not put a damaged or defective rotary heat
exchanger into operation.
Adjusting the rotary heat exchanger
The storage mass of the rotary heat exchanger is fac-
tory set. You may have to adjust the storage mass to the
actual installation conditions, see
‘Adjusting the storage mass’ on page 71

Ensure that permitted values for parameters such as
temperatures or differential pressure are not
exceeded.
1.
Check whether the system has been correctly
installed.
2.
Inspect the rotary heat exchanger for foreign
matter.
3.
Check that the rotor moves freely.
See the manufacturer's documentation
Appendix A ‘Adjusting the storage mass’
4.
Check the rotation direction of the rotor and
change it on the motor controller, if necessary.
Follow the manufacturer's operating instructions.
If the heat exchanger includes a purge sector,
the rotating storage mass passes from the
extract air via the purge sector to the supply
air.
5.
Check that the control module functions correctly.
6.
Check the drive belt tension.
