package.
IMPORTANT: Leave the packing material around the trolley in
place until Step 7.
FASTEN THE RAIL TO THE OPENER
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 (3) over opener pulley. Cut tape.
REMOVE STYROFOAM.
ATTACH THE BELT AND BELT CAP RETAINER
A. C-rail: Slip the belt around the opener pulley (1). The pulley teeth
must engage the belt.
Position the belt cap retainer (2) over the pulley so the two holes in
the cap align with the two holes in the mounting plate. Attach with
hex screws (3).
B. T-rail: Slip the belt around the opener pulley (1). The pulley teeth
must engage the belt.
Insert the second washered screw.

SET THE BELT TENSION
A. C-rail: Remove the packing material from the trolley and leave the
trolley in place on the rail.
At the belt 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 belt idler bracket (4) together. Tighten until
the distance between the belt and the rail is approximately 20 mm.
Do not overtighten.
B. T-rail: Insert the threaded shaft (2) through the hole in the
trolley (1).
By hand, thread the spring trolley nut (3) on the threaded shaft until
finger tight against trolley.
Insert a screwdriver tip (4) into one of the slots of the nut ring (7),
and hold firmly.
Using an open end wrench (5) at the square end (6), slightly rotate
the assembly clockwise until the nut ring (7) is released against the
trolley, providing tension for the best operation of the opener.
Remove "temporary stop" screwdriver.
NOTE: During future maintenance, ALWAYS pull the manual release
handle to disconnect trolley before adjusting belt.
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 (7 feet) 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
(1-1/2") 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 5cm (2") above high point to provide travel
clearance for top edge of door.
INSTALL THE HEADER BRACKET

designated for ceiling mount. Drill 4,5mm (3/16") pilot holes and
fasten the bracket with wood screws (3).
