Return Air Box & Duct Installation
Remove the return air grill from the return air box and
remove the air filter from the return air grill.
Insert the return box from below for ceiling installation (or
from the front for wall installations) and fasten with four
screws through holes provided on the long side of the
box. (see Figure 2.24).
Remove the grill and the filter from the grill frame. Insert
the frame into the box and mount in place with the screws
provided through a hole at each corner of the frame.
Finally, place the air filter into the frame and replace the
grill. Turn the latches a quarter turn to lock the grille in
place. Slide a clamp band (provided with return air box)
over one end of the return air duct. Place that end over
the elliptical flange on the fan coil unit (see Figure 2.25).
Move the clamp over the flange and tighten so the clamp
holds the return air duct securely to the flange.
Follow the same procedures to attach the return air duct
to the return air box (see Figure 2.25).

Direct Mount Filter Box & Ductless Returns
Center filter box over the eliptical flange of fan coil unit
(see Figure 2.26). Mark the (4) hole locations on fan coil
unit and drill holes using 5/32" bit. Mount filter box to unit
using screws provided and insert air filter.
Winter Supply Shut-Off Installation
Simply insert winter supply shut-offs into the room
terminator openings (see Figure 2.27). Wrap the return air
filter in a plastic bag and reinstall it to block the return air
opening. Winter supply shut-offs prevent moisture from
collecting in ductwork during winter months. Be sure to
remove the plastic bag and all winter supply shut-offs
before operating the system
