The top and bottom end bells are shipped separate from
the filter elements. The top end bell has the blower and
power supply.
1. Remove the shipping bolts from the end bells and lay
the bottom end bell on the floor.
2. Insert the pre-filter set down into the bottom end bell.
The gross pre-filter (rigid dark blue) goes down first
beneath the fine pre-filter (blue and white). They
should rest on the four tabs inside the end bell and be
below the inset shoulder that the HEPA seats against.
They may be bowed slightly with tension.
3. Insert the HEPA filter into the bottom end bell until it
rests on the inset shoulder. Only apply pressure to the
frame, not the media and be sure it is squarely seated
in place. Caution: the face of the HEPA cell is now
exposed and the media (pleats) are easily
damaged.
4. Place the carbon adsorber carefully and squarely over
the HEPA face shown in figure C-1. Ensure that the
rubber seal surfaces of the filter gaskets are squarely
mated as shown in figure C-2.
5. Set the top and bell over the stacked filter assembly
taking care that the upper seal of the chemical adsorber
is squarely seated inside the top end bell inner seal
surface.
6. Sandwich the filter assembly with the two aluminum
end plates and insert the clamping bolts and nuts as
shown in figure C-3. The threaded rod, spacer, and
floating clamp bar are installed with the end plates. See
figure D-1 on page 6 for how these parts are installed.
