To prevent possible SERIOUS INJURY or DEATH from electrocution or fire: • Be sure power is not connected to the opener, and disconnect power to circuit BEFORE removing cover to establish permanent wiring connection. • Garage door installation and wiring MUST be in compliance with all local electrical and building codes. • NEVER use an extension cord, 2-wire adapter, or change plug in any way to make it fit outlet. Be sure the opener is earthed. 114A2845 19 INSTALLATION STEP 10 Install the Safety Infrared Reversing Sensors (Optional) It is recommended that safety infrared reversing sensors be connected and aligned correctly to the garage door opener. The force, as measured on the closing edge of the door, should not exceed 400N (40kg). If the closing force is adjusted to more than 400N, this safety system must be installed. IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS When properly connected and aligned, the safety infrared reversing sensors will detect an obstacle in the path of its electronic beam. The sending eye transmits an invisible light beam to the receiving eye. If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener light will flash 10 times. The units must be installed inside the garage so that the sending and receiving eyes face each other across the door, between 100-150mm above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving eye lens. The brackets must be securely fastened to a solid surface such as the wall framing. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary. The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing. Yellow) Facing the door from inside the garage Note: This operator, when used with safety reversing sensor 062153, meets product standard requirements for a monitored sensor system. If the operator detects that the safety sensors no longer function properly, the operator will not close until the sensor continuity has been returned. 114A2845 20 INSTALLATION STEP 11 Fasten the Door Bracket WWARNARNINGINGCAUTIONCAUTION Fibreglass, aluminum or lightweight steel garage doors Follow instructions which apply to your door type as illustrated below or on the following page. A horizontal reinforcement brace should be long enough to be secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel. Figure 1 shows one piece of angle iron as the horizontal brace. For the vertical brace, two pieces of angle iron are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit. NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin and door arm. In this case you will not need the door bracket; proceed to Step 12. SECTIONAL DOORS 1. Centre the door bracket on the previously marked vertical centreline used for the header bracket installation. Note correct UP placement, as stamped inside the bracket. 2. Position the top edge of the bracket 50mm 100mm (2"-4") below the top edge of the door, OR directly below any structural support across the top of the door. 3. Mark, drill holes and install as follows, depending on your door’s construction: Metal or light weight doors using a vertical angle iron brace between the door panel support and the door bracket: • Drill 4.5mm (3/16") fastening holes. Secure the door bracket using the two 8mm x 13mm (1/4"14x5/ 8") self-threading screws. (Figure 2A) • Alternately, use two 8mm (5/16") bolts, lock washers and nuts. (Figure 2B) Metal, insulated or light weight factory reinforced doors: • Drill 4.5mm (3/16") fastening holes. Secure the door bracket using the self-threading screws. (Figure 3) Wood Doors: • Use top and bottom or side to side door bracket holes. Drill 8mm (5/16") holes through the door and secure bracket with 8mm x 65mm (5/16"x2") carriage bolts, lock washers and nuts (not provided). (Figure 4) NOTE: The 8mm x 13mm (1/4"-14x5/8") self-threading screws are not intended for use on wood doors.
