NNUAL AINTENANCE
Your unit is equipped with a wall controller (ACCGSC1 or 40425), which tells when to perform maintenance when the Filter Maintenance
light stays ON. Otherwise, this maintenance must be performed once a year to ensure your unit proper operation for years to come.
Proceed as the Semi-annual Maintenance (Section 9.1), but instead of replacing the prefilter (point 4), discard the complete HEPA Filter
cartridge (including prefilter). Install a new HEPA filter cartridge with a new prefilter on it.
NOTE: In annual maintenance, for 40425 wall controller, press simultaneoustly both
and turn the LED off.
