INSTALLATION Tools you may need 1 2 STEP ONE: PLEASE NOTE - Ensure the bracket is mounted on door at a position of high strength as large forces can be transmitted to the door at this location. Tilt Door Mount Door Bracket flush to top of door at centre position (see fig 1a). Sectional Door Mount Door Bracket about one-third of the way down the top door panel at centre position (see fig 1b).
INSTALLATION (continued) STEP TWO: Determine the centre of the door and continue the vertical line through the header as in FIG 2 )LJ 'UDZ 9HUWLFDO &HQWUH /LQH IURP 'RRU WR +HDGHU +HDGHU 'RRU STEP THREE: Lift the door and find the highest point to which the top of the door reaches. Using an appropriate straight edge and level, transfer the height to the header.
INSTALLATION (continued) STEP SIX: Lay the rail on the ground with channel side facing up. Insert the Traveller and Chain Idler assembly into the end of the rail. Locate chain around the Chain Idler Wheel and through the Traveller as shown (see fig 5). Ensure chain ends are located at a mid-rail position. STEP SEVEN: Connect the chain using the spool and joining links as shown in fig 6. Ensure chain is not twisted.
INSTALLATION (continued) STEP EIGHT: Locate chain at Drive unit end onto drive unit sprocket. Keeping chain taut on sprocket, insert drive unit chassis onto rail and slide forward until the chassis upright hits end of rail (see figs 7a & 7b). STEP NINE: Install Idler bracket inside door end of rail. Keeping door end of chain taut inside Idler Wheel, fit M8 nyloc nut as shown in fig 8. STEP TEN: Tension the chain by tightening the M8 nyloc nut.
