Danger!
All personnel involved with installation, operation and maintenance of this unit should familiarise themselves with the safety section of this manual.
* Applicable for Frigosorb and Econosorb.
10.2 WASHING THE ROTOR
The D-MAX rotor has a distinct advantage over other types of desiccant rotors in that dust and grease can be washed out of the material without the need for reimpregnation
after treatment. In all normal applications however it must be emphasised that washing of the rotor should be considered as a last resort having alleviated all other possible
defects rst.
Caution!
Please contact a DST-representative before attempting to wash the rotor!
