Cabinet Installation
The following is a typical installation of the Complete
Comfort™ Cabinet with an up-flow furnace (see
figure 8).
1. Position the cabinet alongside the furnace with the
access door opening facing outward.
2. Align the cabinet opening on the furnace. (For 5
ton application, use option 1 or 2 (figure 9 or 10).
3. Secure the cabinet to the furnace using sheet
metal screws in the pre-drilled cabinet mounting
holes (see figure 12).
4. Use a butt joint to attach the duct to the upstream
side of the cabinet.
NOTE - If necessary, use sheet metal turning
vanes to improve air movement through
an elbow in the duct.
5. Connect the next section of the duct. If necessary,
use a properly sized wooden block to support a
duct elbow.
6. Use foil tape to seal all duct joints. This prevents
dust from entering the air stream.
7. Insert side rails (D) into the cabinet and use the
provided screws to secure them to the cabinet at
both the top and bottom (see figure 13).
8. Slide the filter into the rail land secure the cabinet
door (see figure 14).
Risk of Carbon Monoxide poisoning.
Can cause injury or death.
Do not operate without Filter Cabinet
door in place. Operation of this equip-
ment without the Filter Cabinet door in
place may cause exhaust fumes to be
drawn into occupied spaces.
