Care and Cleaning
WARNING: Electrical Shock Risk - Always turn off the main power supply to the unit before performing any
cleaning or maintenance!
CAUTION: Do not use extremely hot water or harsh chemicals to clean, as they may deform or deteriorate the
surface of the unit, filter or grille.
1. When the unit will not be used for an extended period of time, turn off the main power supply to the
unit.
2. The unit can be dusted or cleaned with a damp wash cloth, ensuring no moisture gets into the electrical
control panel.
3. If needed, a mild detergent can be used. Do not use any hard abrasives or flammable cleaning products
that can deteriorate the surface.
Cleaning the Air Filter
1. The air filter should be cleaned to remove accumulated dust. Dust that builds up and clogs the air filter,
will decrease air flow and the unit’s performance.
2. Clean the filter at least every six months or more frequently if dust builds up.
WARNING: Before accessing the filter, be sure the power is turned off.
3. To access the filter, push the two tabs inward to release the inner inlet grille.
Note: There are (2) small shipping screws that may need to be removed in order to push the tabs
inward. These screws should have been removed to install the panel, however if they were not or they
were re-installed they will need to be removed.
4. Once the inlet grille has been released, the filter can be removed for cleaning.
5. Vacuum the dust from the filter using a vacuum hose attachment with brush. If needed, the filter can be
washed in lukewarm water and a mild detergent. Allow the filter to air dry before proceeding to the
next step.
6. Once the filter is clean and dry, reinstall it into the inlet grille.
7. Push the inlet grille back up toward the frame of the panel.
8. Push the tabs back outward to lock the inlet grille in place and prevent it from falling.
