RECEIPT INSPECTION: Check material received against packing list. Claims resulting from factory errors must be made within 2 weeks after receipt of goods. INSTALLATION(Reference illustrations on opposite side): 1.Round dampers are furnished as one piece; however, make sure cable end is secure in damper pivot coupling prior to installing. 2.Secure damper in position in duct. Screw or rivet through bearing bracket side pieces-minimum 1 screw per side. Preferred installation method is via#10 speed screws. Do not rack or distort damper. Dampers are 1/4"undersized from nominal dimensions. Position damper to allow best cable run, avoiding tight turns, while keeping adjustment end in its preferred accessible position. Keep adjustment end of cable within 5"of accessible opening if possible. Alternately cables may be left hanging out of ceiling upon installation of air outlet and slipped back in after balancing. 3.Secure the adjustment end of the cable using the nylon clamp. The clamp may be positioned anywhere along cable length to keep adjustment end in accessible position. Do not over tighten. Cable should rotate easily inside the clamp. OPERATION: Dampers may be adjusted by applying a MAT Square Nut driver or a 1/4" hex socket to the male square adjustment end of the cable. Once set,dampers will hold their settings up through the design velocity limits. MAT Square Nut Drivers with 5" shaft length may be purchased from the manufacturer. Optional screwdriver tip units are adjusted with a thin bladed screwdriver. MAINTENANCE: Properly installed Roto-TwistTM dampers require no maintenance of any kind.
