BEFORE YOU BEGIN:
1. Look at the wall or ceiling above the garage door. The header
bracket must be securely fastened to structural supports.
2. Do you have a finished ceiling in your garage? If so, a support
bracket and additional fastening hardware (not supplied) may be
required.
3. Depending on your door's construction, you might need a special
door arm. See your dealer.
4. Do you have an access door in addition to the garage door? If not,
Model 1702E Outside Quick Release Accessory is required.

ASSEMBLY SECTION
FASTEN THE RAIL TO THE OPENER
NOTE: Trolley location is important for programming travel limits
(Step 17). Do not change location of trolley!
Place packing material under the opener to protect the opener cover.
For convenience, place a support under the door end of rail.
A. C-rail: Remove the four washered screws (1) from the top of the
opener.
Place the two rail brackets (2) horizontally across the top of the
opener, aligning the screw holes with those on the opener.
Replace the screws loosely through the brackets into the opener.
Slide the rail under the brackets as far forward as possible, until
the round stop (3) on top of the rail rests against the nearest
bracket. Tighten the four screws securely. CAUTION: Use only
these screws! Use of any other screws will cause serious
damage to the door opener.
B. T-rail: Remove two of the 4 washered screws (1) from the top of
the opener. Align rail at an angle with the opener so one hole in rail
and opener line up (2).
Thread one of the washered screws part way in. CAUTION: Use
only these screws! Use of any other screws will cause serious
damage to the door opener.
Align rail and styrofoam over opener sprocket. Cut tape from rail,
chain and styrofoam (3).
REMOVE STYROFOAM.
ATTACH THE CHAIN AND SPROCKET COVER
A. C-rail: Slip the chain around the opener sprocket (1). The sprocket
teeth must engage the chain.
Align the tabs on the sprocket cover (2) with the slots in the
mounting plate. Squeeze cover and insert tabs.
B. T-rail: Position chain over the opener sprocket (1). If necessary,
loosen the outer nut on the trolley to obtain more chain slack.
Insert the second washered screw. CAUTION: Use only the
screw previously removed from the opener! Tighten both
screws securely through the rail into the opener as shown.
Align the tabs on the sprocket cover (2) with the slots in the
mounting plate. Squeeze cover and insert tabs.

SET THE CHAIN TENSION
A. C-rail: Remove the packing material from the trolley and leave the
trolley in place on the rail.
At the chain tension bracket (1), tighten the nut (2) with a wrench
against the spring (3). As the nut travels, the spring will pull the
tension bracket and the chain idler bracket (4) together. Tighten
until the distance between the chain and the rail is approximately
5-6 mm. Do not overtighten.
B. T-rail: Spin the inner nut (1) and lock washer down the threaded
shaft, away from the trolley.
To tighten the chain, turn the outer nut (2) clockwise. As you turn
the nut, keep the chain from twisting. When the chain is
approximately 13mm above the base of the rail at its midpoint (3),
re-tighten the inner nut to secure the adjustment. Sprocket noise
can result if chain is too loose or too tight.
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 manual release
handle to disconnect trolley before adjusting chain.
ASSEMBLY OF YOUR OPENER IS NOW COMPLETE.
INSTALLATION SECTION
Wear protective goggles when working overhead to protect your
eyes from injury.
Disengage all existing garage door locks to avoid damage to the
garage door.
To avoid serious personal injury from entanglement, remove all
ropes connected to the garage door before installing the opener.
Installation of this product shall comply with ZH1/494, VDE 0700
Part 238, and VDE 0700 Part 1.
It is recommended that the opener be installed 2,1m or more above
the floor where space permits.
POSITION THE HEADER BRACKET
The header bracket must be rigidly fastened to a structural
support of the garage. Reinforce the wall or ceiling with a
40mm board if necessary. Failure to comply may result in
improper operation of safety reverse system.
You can attach the header bracket either to the header wall (1) or to
the ceiling (3). Follow the instructions which will work best for your
particular requirements.
With the door closed, mark the vertical centerline (2) of the garage
door. Extend line onto header wall above the door.
Open door to highest point of travel. Draw an intersecting horizontal
line on header wall 50mm above high point to provide travel clearance
for top edge of door.
INSTALL THE HEADER BRACKET
A. Wall Mount: Center the bracket (2) on the vertical guideline (1)
with the bottom edge of the bracket on the horizontal line (6) (with
the arrow pointing toward the ceiling).

Mark either set of bracket holes (4 or 5). Do not use the holes
designated for ceiling mount. Drill 4,5mm pilot holes and fasten
the bracket with wood screws (3).
B. Ceiling Mount: Extend vertical guideline (1) onto the ceiling.
Center the bracket (2) on the vertical mark no more than 150mm
from the wall. Be sure the arrow is pointing toward the wall.
Mark holes designated for ceiling mount only (4). Drill 4,5mm pilot
holes and fasten the bracket with wood screws (3). For concrete
