4) Measuring from one end of the foam piece, cut off a piece approximately 9" long. Clean surfaces and peel off the adhesive liner and place the adhesive side of the foam on the inside of the inlet, fitting tightly to the inlet's door, sealing the opening. See Figure 7B. With the remaining 6" piece, place on the outside on the inlet, fitting tightly to the edge of the door, sealing any gap. See Figure 7B. Repeat for other side of inlet. Installation complete. Figure 7B FRONT VIEW SIDE VIEW OPERATION ) When inlet will be used for ventilation, unhook S-hook from guide link as shown in Figure 8, and allow chain to hang down. Figure 8 FRONT VIEW SIDE VIEW ADJUSTMENT ) To achieve a higher static pressure in room, lower counterweight slightly. ) To achieve a lower static pressure in room, raise counterweight slightly. MAINTENANCE Baffle must be clean and free of debris in order for inlet to function properly.
