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.

NOTICE!
Risk of damage to property from extreme pres-
sure drop!
An extreme pressure drop between the supply air
and extract air flows can damage the heat
exchanger.
–
Ensure that the maximum differential pressure
(approx. 1000 Pa, depending on unit design) is
not exceeded.
–
Check differential pressure on pressure monitors
according to the specified intervals.
Check and, if necessary, clean the plate heat
exchanger to remove foreign matter and contami-
nation.
