Cleaning and HEPA Filter Replacement
Use the following information for filtering cleaning and replacement.
STEP 1. Loosen all ¼-turn fasteners.
NOTE: The diffuser face must be supported when this occurs, as the face
will swing open and hang by the retainer cables. Figure 14 shows
the face screen in the secured position and Figure 15 shows the face
screen opened and a new filter being inserted.
STEP 2. For HEPA filter rack models, loosening the wing nuts will allow filter
to be removed (Figure 16).
STEP 3. Align gel seal on replacement filter with knife-edge in diffuser back pan and
push for tight seal. Replace filter support and tighten wing nuts as
shown in Figure 16.
STEP 4. Restore diffuser face and lock all ¼-turn fasteners. Figure 14 shows the
location of ¼-turn fasteners.
Note: Figure 13 shows the profile and critical dimensions within a RadiaTec with HEPA
filter rack. Dimensions for this example are based on Maryland-based Filtertech
Company's HEPA filter model. These dimensions will vary by filter manufacturer. Verify
filter dimensions and gel seal location prior to ordering replacement filters.
