As you turn the nut, keep the chain from twisting. • When the chain is approximately 1/2" above the base of the T-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 12 – 27 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 30). 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.
ONE-PIECE Door Without Track Read the Safety Instructions on page 12. They also apply to doors without tracks. Unfinished Ceiling Header Wall Vertical Centerline • Close the door and mark the inside vertical centerline of your garage door. Extend the line onto the header wall above door. If headroom clearance is minimal, you can install the header bracket on the ceiling. See page 14.
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 T-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 T-rail to clear the spring. • Position the cable 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. Follow instructions which apply to your door type as illustrated. SECTIONAL Door & ONE-PIECE Door with Track A 2x4 laid flat is convenient for setting an ideal door-to-T-rail distance. • Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.
Installation Step 5 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 before installing the opener. The bracket and fastening hardware are not supplied.
Installation Step 6 Install the Deluxe Lighted Console Wall Control • Strip 1/4" of insulation from one end of the bell wire; connect the wire to the two screw terrrlinals on the back of the Wall Control by color, white to white, and white/red to red. • Locate the Wall Control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from all moving parts of the door and door hardware. Fasten the Wall Control securely with 6ABx1" screws.
Installation Step 7 Install the Light and the Lenses Install the lights • Install a 75 watt maximum light bulb in each socket. The lights will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the lights will turn OFF. • If the bulbs burn out prematurely due to vibration, replace with "Garage Door Opener" bulbs. Lens Guide Lens Tab Install the lenses The Force Adjustment Control and Smart Button are located on the back panel.
Installation Step 9 WARNING Electrical Requirements To prevent electrocution or fire, installation and wiring must be in compliance with local electrical and building codes. 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. If the plug doesn't fit into the outlet you have, contact a qualified electrician to install the proper outlet.
The Protector 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 injured or 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 on each side of the garage door as shown on page 21. 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.
• Plug a 2-strand wire connector into each unit as shown in Figure 6. Insert the connector and push until you hear a click. The white tab on the sensor should be flush with the back of the connector. • Run wires from both sensors to the opener as shown in Figure 7. Use insulated stapies to secure the wire to the wall and ceiling. • Connect both sets of wires to the opener terminals by color, white/black to black and white to white. • Plug in the opener. Make sure the Lock Feature is off.
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. Follow instructions which apply to your door type as illustrated below or on page 25. 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.
All ONE-PIECE Door Installation Procedure Please read and comply with the warnings and reinforcement instructions on page 24. They apply to one-piece doors also. Header Wall — Finished Ceiling — 2x4 Support Horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, aluminum, steel, door with glass panel, etc.).
Installation Step 12 Connect Door Arm to Trolley Follow instructions which apply to your door type as illustrated below and on page 27. SECTIONAL Doors Only Make sure garage door is fully closed. Pull the manual 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.
All ONE-PIECE Doors Door Bracket Assemble the Door Arm: • Fasten the straight and curved door arm sections together to the longest possible length (with a 2 or 3 hole overlap). • With the door closed, connect the straight door arm section to the door bracket with a clevis pin. • Secure with a ring fastener.
Adjustment Section: Pages 28 - 30 Adjustment Step 1 Adjust the UP and DOWN Limits Improper adjustment of the travel limits could interfere with the proper operation of the safety reverse system. See page 30. The door might not reverse when required and could serlously iniure or kill someone under it. Limit adjustment settings regulate the points at which the door will stop when moving up or down. The door will stop in the up direction if anything interferes with door travel.
Adjustment Step 2 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 amount 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 30.
Adjustment Step 3 WARNING Test The Protector System® 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 remote control push button to open the door. • Place the opener carton in the path of the door. • Press the remote control push button to close the door. The door will not move more than an inch, and the opener light(s) will flash for 5 seconds.
