Assembly Section: Pages 7 – 10 To avoid installation difficulties, do not run the garage door opener until instructed to do so. Assembly Step 1 Assemble the Rail & Attach the Chain Pulley Bracket RAIL BACK (TO OPENER) • Align the 4 rail sections on a flat surface exactly as shown. Center sections are interchangeable. Front and back sections are not. Be sure the arrow labels are pointing toward the door.
Hardware Shown Actual Size Assembly Step 2 Install the Trolley on the Rail • Attach the threaded shaft to the trolley with the lock washer and nuts as shown. Nut 5/16" Lock Washer 5/16" Lock Washer 5/16"-18 TO GA RA GE DO OR Trolley Threaded Shaft Outer Nut 5/16" Trolley Inner Nut 5/16" TO GA RA GE DO OR TO GA RA GE DO OR Trolley • As a temporary stop, insert a screwdriver into the hole in the front end of the rail. • Slide the trolley assembly along the rail to the screwdriver stop.
Assembly Step 4 WARNING Attach the Chain & Rail Support Bracket Serious injury can result if fingers become entangled in moving opener sprocket. Attach sprocket cover securely. Never operate opener while your hand is near the opener sprocket. • Remove the chain end from the carton and fasten it to the trolley with a master link from the hardware bag. See master link procedure, Figure 1. • With the trolley against the screwdriver, dispense the chain around the pulley.
Assembly Step 5 Tighten the Chain • Spin the inner nut and lock washer down the threaded shaft, away from the trolley. • To tighten the chain, turn outer nut in the direction shown. As you turn the nut, keep the chain from twisting. • When the chain is approximately 1/2" above the base of the rail at its midpoint, re-tighten the inner nut to secure the adjustment. Sprocket noise can result if chain is either too loose or too tight.
Installation Section: Pages 11 – 23 Installation Step 1 WARNING Determine Header Bracket Location If the header bracket is not rigidly fastened to a structural support on the header wall or ceiling, the safety reverse system may not work properly (see page 26). The door might not reverse when required, and could cause serious injury or death. The garage door springs, cables, pulleys, brackets and their hardware are under extreme tension. Do not attempt to loosen, move or adjust them yourself.
You can attach the header bracket either to the wall above the garage door, or to the ceiling. Follow the instructions which will work best for your particular requirements. Installation Step 2 Install the Header Bracket Fasten the Header Bracket to the Wall • Center the bracket on the vertical guideline with the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).
Installation Step 3 Attach the Rail to the Header Bracket • Position the opener on the garage floor below the header bracket. Use packing material as a protective base. If the door spring is in the way you'll need help. Have someone hold the opener securely on a temporary support to allow the rail to clear the spring. • Position the chain pulley bracket against the header bracket. • Align the bracket holes and join with a clevis pin as shown. • Insert a ring fastener to secure.
Installation Step 4 CAUTION Position the Opener To prevent damage to steel, aluminum, fiberglass or glass panel doors, do not rest the opener on the door without using a 2x4. A 2x4 laid flat is convenient for setting an ideal door-to-rail distance. • Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough. • Open the door all the way and place a 2x4 laid flat on the top section beneath the rail.
Installation Step 5 W WARNING Hang the Opener The opener could fall and injure someone if it is not properly secured. Fasten the opener securely to structural supports of the garage. Two representative installations are shown. Yours may be different. Hanging brackets should be angled, Figure 1, to provide rigid support. On finished ceilings, Figure 2, attach a sturdy metal bracket to structural supports in ceiling before installing the opener. The bracket and fastening hardware are not provided.
Installation Step 6 W WARNING Install the Door Control Children operating or playing with a garage door opener can injure themselves or others. The garage door could close and cause serious injury or death. Install the Door Control (or any additional push buttons) out of the reach of children and away from all moving parts of the door and door hardware, but where the garage door is visible. Do not allow children to operate the push button or the remote controls.
Installation Step 7 Install the Light • Install a 75 watt maximum light bulb in the socket. The light will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the light will turn OFF. • If the bulb burns out prematurely due to vibration, replace with a standard neck "Garage Door Opener" bulb. 75 Watt Max. Light Bulb Installation Step 8 WARNING Attach the Emergency Release Rope and Handle Do not use the red handle to pull the door open or closed.
Installation Step 9 To prevent electrocution or fire, installation and wiring must be in compliance with local electrical and building codes. Do NOT use an extension cord, 2-wire adapter, or change the plug in any way to make it fit your outlet. To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet.
Safety Reversing System Information you'll need before you begin the installation of the safety reversing sensor. The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction. This is a required safety device and cannot be disabled. WARNING Without a properly working safety reversing sensor, persons (particularly children) could be killed by a closing garage door. Read and follow all instructions.
Installation Step 10 Install the Safety Reversing Sensor Figures 2 and 3 show assembly of brackets and "C" wrap based on the recommended installation of the sensors as shown on page 19. However, Figures 4 and 5 are variations which may fit your installation requirements better. Make sure the wraps and brackets are aligned so the sensors will face each other across the garage door. • Fasten the "C" wraps to the mounting brackets having square holes, using the hardware shown in Figure 2.
Figure 6 • Center each sensor unit in a "C" wrap with lenses pointing toward each other across the door (see Figure 6). • Secure sensors with the hardware shown. Finger tighten the wing nut on the receiving eye to allow for final adjustment. Securely tighten the sending eye wing nut. • Run the wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling. • Strip 1/4" of insulation from each set of wires.
Installation Step 11 CAUTION Fasten Door Bracket To prevent damage to steel, aluminum, fiberglass or glass panel doors, always reinforce the inside of the door both vertically and horizontally with an angle iron. A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the height of the top panel. The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a "U"-shaped support.
Installation Step 12 Connect Door Arm to Trolley Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the door) about 2” as shown in Figures 1, 2 and 3. Figure 1: • Fasten straight door arm section to outer trolley with a clevis pin. Secure the connection with a ring fastener. • Fasten curved section to the door bracket in the same way. Figure 2: • Bring arm sections together.
Adjustment Section: Pages 24 – 26 Adjustment Step 1 W WARNING Adjust the UP and DOWN Limits Improper adjustment of the travel limits could interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone under it. Test the safety reverse system following all adjustments to the travel limtis. See page 26. Do not make any limit adjustments until the safety reversing sensors are completely installed.
Adjustment Step 2 W WARNING Adjust the Force Too much force on the door will interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone under it. Do not increase the force beyond the minimum required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Test the safety reverse system following all adjustments to force levels. See page 26.
Adjustment Step 3 WARNING W Test The Safety Reversing Sensor Without a properly working safety reversing sensor, persons (particularly children) could be seriously injured or killed if trapped by a closing garage door. Repeat this test once a month. • Press the Door Control button to open the door. • Place the opener carton in the path of the door. • Press the Door Control button to close the door. The door will not move more than an inch, and the opener light will flash.
