MAINTENANCE
Periodic maintenance is required to ensure that the XL3500 operates properly. A
severely polluted environment can foul an air purifier plate in as little as four
weeks or as long as a year. Shown here are basic maintenance procedures that
should be carried out to keep your unit running at top performance.
Pre-Filter/HEPA Filter Cleaning:
(Turn to page 7 for removal instructions.)
You have one way to clean filters:
When filter is visibly dirty, simply remove the pre-filter or HEPA filter and
clean the heavy particulate from the screen with a hand-held vacuum.
This method will extend the life of the screen/filter.
All filters are washable except for the charcoal filter.
Fan Blade and Front Grill Cleaning:
(Take off front/reinstall grill method.)
To remove for cleaning:
1. Remove the 4pcs screws on the front grill.
2. Remove the front grill.
To reinstall after cleaning:
Put the front grill in the original position and
screw it.
Cleaning Information:
Wipe off fan blade and front grill with damp washcloth. The fan requires no
maintenance. If the fan squeaks, a drop of lightweight machine oil may be needed
on the fan shaft.
