Visual and functional check of the dryer should be carried out daily:
• Check the dryer for any external damage. Assess and eliminate any defects found.
• If the red service light appears, the dryer must be serviced. Contact the distributor service department and re-quest a dryer
service kit.
• Remove any loose dust or dirt from the dryer; clean all surfaces that appear to have attracted unwanted contaminants.
• Check the dewpoint sensor display (where applicable). If the dew point is not achieved the dewpoint reading on the display
will alternate with “dewpoint alarm” every 5 seconds. The no-volt alarm will also activate.
Contact the distributor service department and request a product service.
