ASSEMBLY IF UNIT IS NOT ASSEMBLED
Set main housing unit in place, refer to figure 12,
with metal screws provided, attach the right and left
panels to the bottom lip of the channel as shown.
Then place the top panel in place and secure it to
the top of the side panels with the metal screws. Se-
cure the front of the side panels with four screws to
brackets that are welded to both sides of the main
housing. Where the side panels overlap in the back
fasten the overlap with the metal screws. Install the
slip joint onto the back of the hood as shown. When
the hood is all assembled slide the felt, with the metal
slip joints into the square hole in the back.
ASSEMBLY OF THE BLOWER & FILTER
HOUSING BOX
Refer to figures 14 and 16, place fan assembly on the
fan housing base so that the holes in the brackets
align with the bolts that are already in the base. Place
the washers and nuts in place, but don’t tighten
down the nuts yet. Next, attach the side panels with
the metal screws that were provided. Then slide the
bottom channel in place so that the holes align with
the side panel holes and secure with metal screws
(the holes are on each end of the channel). Do the
same with the top channel and secure tightly.
Now slide the blower assembly housing towards the
back of the main housing so that the base slides un-
derneath the main housing, about 2-3 inches, mak-
ing sure that the side panels are against the main
housing hood and secure it with the metal screws.
Make sure that the fan outlet lip slides into the felt
lined square hole in the hood and forms a tight seal
around the lip. Now tighten the nuts. Set the large
cover in place so that the front lip slides into the slip
joint in the back of the hood.
Place the air filters into the channels. Place the filter
cover in place.
The completed assembly, without the fans, should
look like the drawing in Figure 15.
