Caution
When current feed is not disconnected at all poles, there is a risk of crushing and scraping
to the limbs through sudden running of the rotor caused by an automatic cleaning run or
automatic re-start after power failure.

Maintenance Work
The maintenance work must be carried out in line with the instructions of the rotor
manufacturer (ask if required).
Desiccant Rotor HRS – Periodic Maintenance
 Check rotor for hygiene, foreign bodies, contamination, damage and corrosion
 Check sealing strips for contamination, foreign bodies and contact pressure (see above)
 Check drive belt for wear and tension, shorten (see above) or change if necessary
 Check rotor for imbalance and lateral trueness
 Check bearing for incorrect heating, vibration or running noises and change if necessary
(no later than the end of the theoretical service life)
 Check functioning of rotor control, align sensor if necessary
Desiccant Rotor HRS – Maintenance when necessary
 Rectify foreign bodies, contamination, damage and corrosion
 Clean body of rotor in line with rotor manufacturer's instructions. Depending on the rotor
type, wet cleaning may lead to the destruction of the rotor!
 Clean sealing strips, change if there is abrasion
 Adjust contact pressure of sealing strips (see above)
 Balance or align rotor
