TYPE 1 INSTALLATION
TFP Directly Connected to
Forced Air Heating System
1. | Install 7” port collar (provided) on top and |
| bottom of TFP (Fig. 1). Use (4) 8/32” X 3/8” |
| screws (provided). |
2. | Remove protective backing from pieces of |
| foam and stick them to the 4 corners of the TFP |
| on the side being mounted against the plenum. |
3. | Remove the 4 mounting bolts from the back of the |
| TFP cabinet. (Fig. 1) |
4. | Attach top and bottom mounting brackets |
NOTE: Do not support the weight of the TFP on the duct. Duct must be open and not pinched.
NOTE: Due to possible noise transfer through the duct system, it may be preferable in some situations to hang the TFP a short distance from the plenum, and connect by running flexible ducting between them. Four nylon hanging straps are provided for this option.
| (provided) vertical to the TFP cabinet and |
| reinstall mounting bolts. |
5. | Lift the TFP into position. Edge of TFP must be |
| positioned on plenum to allow clearance |
| needed for latches. |
6. | Install the (4) 8/32” X 3/4” mounting screws |
| (provided) through the brackets and into position. |
| Tighten and secure. |
7. | TFP should now sit securely against the plenum |
| with the foam in between. |
8. | Cut 2 - 7” holes in the plenum. Install ducting to |
| join TFP to the return air plenum (Fig. 2). |
