5.13 Heating and ventilation system maintenance
Important notice on the heating and ventilation system
The heating system of the machine is equipped with a fine-dust filter.
The fresh air drawn in by the heater fan is cleaned by the fine-dust filter.
The volume of warm air flowing out of the air vents decreases as filter contamination
increases: the fine-dust filter must be cleaned as required, however it must replaced
every 500 operating hours at the latest!
Health hazard! In order to comply with the required safety measures
regarding occupational safety and health, malfunctioning or dirty fine-dust
filters must be replaced by new ones!
