Air King AIG6 Wing Nut Screws Terminal Box, Washer Handle, Hole Shaft, Black, Damper Transition

NOTE: When using insulated flex duct, it is recommended that the inner vinyl core be screw clamped or taped to the inlet and outlet and that the vapor barrier surrounding the insulation be taped to the fan housing.

NOTE: When attaching flex duct to the collar/damper combination and an immediate elbow is necessary, be certain that the elbow is installed with a "soft" bend to allow damper blades to operate properly.

SECTION 7

Installing Optional Balancing Damper

Some kits include an optional balancing damper to allow for adjustment of the system. The damper may be used where the grills will be connected using branches of unequal length or where the flow will need to be balanced for any reason. To Install the optional damper:

1.The damper must be installed on the branch with the least restriction. This is generally the duct that is shortest or has the fewest bends.

2.Drill a 5/16" hole approximately 1-1/2" from the edge on the flat side of the “Y” transition.

3.Insert the shaft of the damper into the hole drilled in step 2. Place the washer, handle, then wing nut onto the shaft (Figure 8).

2.Run wiring from an approved wall switch carrying the appropriate rating. One neutral (white) and one hot (black lead connected to the switch). Secure the electrical wires to the housing with an approved electrical connector. Make sure you leave enough wiring in the terminal box to make the connections to the fan’s pre-wired electrical terminal strip.

3.Insert the white wire from the house into the terminal strip port labeled “N” and tighten using a small regular screwdriver. Insert the black wire from the wall switch into the terminal strip port labeled “L” and tighten using a small regular screwdriver. Since the motor is isolated within a plastic housing, grounding is not necessary (Figure 10).
