F500 WHOLE HOUSE/ LIGHT COMMERCIAL HEPA FILTRATION SYSTEM
3 68-0263-2
PLANNING THE INSTALLATION
Selecting Mounting Position and Location
The F500 can be suspended from exposed ceiling joists or the
ceiling surface, or it can be floor-mounted.
1. Install the F500A in a conditioned space or the F500B in
an unconditioned space using these guidelines.
2. Plan the unit location to minimize duct lengths.
3. Locate an existing electrical outlet with the appropriate
current rating to plug in the power cord. (If an outlet is
not available, have a qualified electrician install one.)
4. Choose a location that is readily accessible for checking
and replacing the filter. (Allow at least 26-1/2 in. (673
mm) clearance in front of the unit.)
Planning Ducting
The F500 can be mounted to the whole-house forced air
system using a bypass configuration or can be independently
ducted to stand alone. See Fig. 2, 3, and 4 for typical
installations.
• The Whole House/Light Commercial HEPA air cleaner has
4 in. x 10 in. duct flanges to easily attach the external
ductwork.
• The intake port can be moved to a more convenient
location, if necessary:
— Simply cut a new 4 in. x 10 in. hole in the desired loca-
tion and block off the old hole.
— Reattach the duct flange over the new hole.
• A transition can be used to connect round ducting to the
Whole House/Light Commercial HEPA System.
— Keep duct sizes as large as possible throughout the
installation (8 in. minimum diameter ducting is recom-
mended).
— Keep intake and exhaust duct runs as short as possi-
ble with few bends or elbows.
• The F500 can be installed with a heat recovery ventilator.
