Warranty 40

To prevent damage to garage door and opener:

• ALWAYS disable locks BEFORE installing and operating the opener.

• ONLY operate garage door opener at 120V, 60 Hz to avoid malfunction and damage.

To prevent possible SERIOUS INJURY OR DEATH:

• ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door may not reverse when required.

• NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their hardware, all of which are under EXTREME tension.

• Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing and operating garage door opener to avoid entanglement.

Preparing your garage door

Before you begin:

• Disable locks.

• Remove any ropes connected to garage door.

• Complete the following test to make sure your garage door is balanced and is not sticking or binding:

1. Lift the door about halfway as shown. Release

the door. If balanced, it should stay in place, supported entirely by its springs.

2. Raise and lower the door to see if there is any

binding or sticking.

If your door binds, sticks, or is out of balance, call a trained door systems technician.

Tools needed

During assembly, installation and adjustment of the opener, instructions will call for hand tools as illustrated below.

Planning

Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener.

Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.

• Installation Step 1 – Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural supports.

• Installation Step 5 – Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware may be required.

• Installation Step 10 – Depending upon garage construction, extension brackets or wood blocks may be needed to install sensors.

• Installation Step 10 – Alternate floor mounting of the safety reversing sensor will require hardware not provided.

• Do you have an access door in addition to the garage door? If not, Model 1702LM Outside Quick Release is required. See Accessories page.

• Look at the garage door where it meets the floor. Any gap between the floor and the bottom of the door must not exceed 1/4" (6 mm). Otherwise, the safety reversal system may not work properly. See Adjustment Step 3. Floor or door should be repaired.

SECTIONAL DOOR INSTALLATIONS

• Do you have a steel, aluminum, fiberglass or glass panel door? If so, horizontal and vertical reinforcement is required (Installation Step 11).

• The opener should be installed above the center of the door. If there is a torsion spring or center bearing plate in the way of the header bracket, it may be installed within 4 feet (1.22 m) to the left or right of the door center. See Installation Steps 1 and 11.

• If your door is more than 7 feet (2.13 m) high, see rail extension kits listed on Accessories page.

Tighten the Chain

ALL MODELS

• Spin the inner nut and lock washer down the trolley 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" (13 mm) 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.

NOTE: When installation is complete, you may notice some chain droop with the door closed. This is normal. If the chain returns to the position shown when the door is open, do not re-adjust the chain.

NOTE: During future maintenance, ALWAYS pull the emergency release handle to disconnect trolley before adjusting chain.

You have now finished assembling your garage door opener. Please read the following warnings before proceeding to the installation section.

IMPORTANT INSTALLATION INSTRUCTIONS

1. READ AND FOLLOW ALL INSTALLATION WARNINGS AND INSTRUCTIONS.

2. Install garage door opener ONLY on properly balanced and lubricated garage door. An improperly balanced door may not reverse when required and could result in SEVERE INJURY or DEATH.

3. All repairs to cables, spring assemblies and other hardware MUST be made by a trained door systems technician BEFORE installing opener.

4. Disable all locks and remove all ropes connected to garage door BEFORE installing opener to avoid entanglement.

5. Install garage door opener 7 feet (2.13 m) or more above floor.

6. Mount emergency release handle 6 feet (1.83 m) above floor.

7. NEVER connect garage door opener to power source until instructed to do so.

8. NEVER wear watches, rings or loose clothing while installing or servicing opener. They could be caught in garage door or opener mechanisms.

9. Install wall-mounted garage door control:

• within sight of the garage door.

• out of reach of children at minimum height of 5 feet

(1.5 m).

• away from ALL moving parts of the door.

10. Place entrapment warning label on wall next to garage door control.

11. Place manual release/safety reverse test label in plain view on inside of garage door.

12. Upon completion of installation, test safety reversal system. Door MUST reverse on contact with a 1-1/2” (3.8 cm) high object (or a 2x4 laid flat) on the floor.

INSTALLATION STEP 1

Determine the Header Bracket Location

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

SECTIONAL DOOR AND ONE-PIECE DOOR WITH TRACK

1. Close the door and mark the inside vertical centerline of the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet (1.2 m) of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling (see page 10) when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2" (1 cm).)

If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown here and on page 13.

3. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" (5 cm) above the high point. This height will provide travel clearance for the top edge of the door.

Proceed to Step 2, page 14.

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise garage door might not reverse when required. DO NOT install header bracket over drywall.

• Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware, all of which are under EXTREME tension.

• ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door might not reverse when required.
