YouhaveinyourhandtheASKOServiceManualfor

the new generation of dryers that are friendly to the

environmentinboththeirmanufactureanduse.

Thisnewgenerationofdryershasbeendesignedfor

easeofservicing. By thiswemean that it'sasimple

job, for example, to replace a damaged side panel.

That's why we've changed the design from a one-

piececasingtoasplitcasing.

Tosecurepartsandwiring, wehavereplaced many

of the screws by plastic snap fasteners, and certain

parts have integrated ribbon cabling, all for

simplifyingservice.

We have also integrated service aids, such as hooks
