Figure 8
The four thumb screws that hold the two outlet collar
guides must be removed; set the guides aside and
reinstall the thumb screws, (see figures 9 and 10).

Figure 10
The adapter and duct are positioned on the unit front so
the four slots in the adapter fit over the thumb screws.
Rotate the adapter so the thumb screws are at the end of
the slots and tighten the screws; see figure 11.

2.6 Negative Air Ducting
The Phoenix Guardian can be used to filter and exhaust
air from a space. By exhausting to outside the space, the
space will be under a slight negative pressure. This will
help prevent airborne particles from leaving the space,
since the negative pressure will draw air in through
openings in the space’s exterior.
The quantity of air exhausted depends on how the unit is
ducted and which speed is used. One or two ducts can
be directed outside. If all the filtered air is ducted outside,
this would result in up to 1300 CFM being exhausted on
high speed and an equal amount of fresh air being drawn
in.
CAUTION: Exhausting too much air from a space with
open combustion devices (e.g. furnace, fireplace or
water heater) can cause those devices to backdraft.
This can contaminate the space with potentially fatal
gases. In such cases, the Phoenix Guardian must be
used in one of the following three ways: (A) as a filtering
unit only. Exhausting no air from the space and thus
causing no negative pressure or backdrafting. (B)
Exhausting a very limited amount of air which does not
cause backdrafting. In case B, the open combustion
devices must be thoroughly checked to guarantee that
they do not backdraft while the Phoenix Guardian is
running. (C) direct one or more outlet ducts from the
Guardian to the room with the open combustion
device(s). This will positively pressurize the room, thus
preventing backdrafting. As in case B, those
combustion devices must be checked after the
Guardian is running to guarantee that they are not
backdrafting.
One duct can be directed outside, exhausting a portion
of the filtered air. The rest of the filtered air can be
recirculated inside the space with or without outlet
