Wayne-Dalton 9900 Thermowayne Thermometer User Manual


 
Locate the center of the door and mark a vertical pencil line on the spring pad.
Then measure the distance from the center of the mounting hole in the end
bearing bracket to the top of the door. Using that same distance, mark a horizon-
tal line on the spring pad, measuring up from the top of the door. Position the
center bearing bracket along the vertical pencil line on the spring pad as shown.
In addition, position the center bearing bracket halfway over the horizontal
pencil line. This will level the torsion tube through the end bearing brackets when
installed. Attach the center bearing bracket to the spring pad using (2) 5/16 x 1-
5/8 lag screws and (1) 5/16 x 2 tamper-proof lag screw.
IMPORTANT! Use the 5/16 x 1-5/8 tamper-proof lag screw ONLY if spring
pad is mounted over masonry.
IMPORTANT! Tamper-proof lag screw MUST be attached through the bottom
hole of the center bearing bracket.
Facing the inside of the door, lay the torsion tube on the floor. Lay the black
color coded winding cone with spring and cable drum on the floor at the right end
of the tube. Then lay the red color coded winding cone with spring and cable
drum on the floor at the left end of the tube.
NOTE: Right and left hand is always determined from inside the building looking
out.
NOTE: Some lighter weight doors are provided with only (1) torsion spring.
Identify the spring(s) provided as either right hand wound (red winding cone),
which goes on the LEFT HAND SIDE or left hand wound (black winding cone),
which goes on the RIGHT HAND SIDE.
NOTE: The set screws used on all Torsion Counterbalance cable drums and
winding cones are now painted red. DO NOT identify right and left hand side by
the set screws.
Slide the nylon center bushing onto the torsion tube followed by the spring(s) and
cable drums. The nylon center bushing, spring(s), and cable drums must be
positioned as shown in the illustrations. With assistance, pick up the torsion
tube assembly and slide the other end the of tube through one end bearing
bracket. Lay the torsion tube into the center bearing bracket and slide the loose
end of the tube into the opposite end bearing bracket. Position the torsion tube
so that equal amounts of the tube extend from each end bearing bracket.

Slide the nylon center bushing into the end of (1) stationary spring cone and
align the cone(s) with the holes in the center bearing bracket. Secure the
spring(s) to the center bearing bracket with (2) 3/8-16 x 1-1/4 bolts and nuts.
IMPORTANT! Springs under tension can be dangerous. Spring warning tag
must be attached to center bearing bracket in obvious sight. If this tag is
missing, contact Wayne-Dalton Corp. for free replacements.
Clamp locking pliers onto both vertical tracks just above the third roller. This
is to prevent door from raising while winding the spring(s).
WARNING!
FAILURE TO CLAMP TRACK CAN ALLOW DOOR TO RAISE AND
CAUSE SEVERE INJURY OR DEATH.
Thread the counterbalance cables behind the rollers and around the back side of
the cable drums. Before hooking the counterbalance cables into the cable drums,
slide the loose cable buttons against the crimped buttons and with a pair of pliers,
bend a 90 degree angle in the counterbalance cable.
Hook the counterbalance cables into the cable drums. Slide the left hand cable
drum against the left hand end bearing bracket and tighten the set screws in the
cable drum. Rotate the left hand cable drum until the counterbalance cable is
taut. CABLE ENDS MUST WRAP DRUM 1/2 TO 3/4 TURN. Clamp locking
pliers to the torsion tube and brace it against the jamb to hold the counterbalance
cable taut.
Slide the right hand cable drum against the right hand end bearing bracket and
rotate the cable drum until the counterbalance cable is taut. Tighten the set
screws in the cable drum.
IMPORTANT! Tighten set screws one (1) full turn after making contact with
the torsion tube. Counterbalance cable tension MUST be equal for both sides.

Position a ladder slightly to the side of spring so that the winding cone is easily
accessible, yet your body is not in the path of the winding bars. Check the
tag(s) attached to the spring(s) for the number of required spring turns.

65 Door Height = Approx. 7 Turns
66 Door Height = Approx. 7-1/4 Turns
68 Door Height = Approx. 7-1/4 Turns

Inserting winding bars into holes of winding cone, one after the other, rotate
winding cone upward toward ceiling 1/4 turn at a time until correct number of
turns for your door height is achieved. As the last 1/4 turn is achieved, insert
winding bar in the bottom hole of the winding cone and gradually let tension
OFF the spring, allowing the lower bar to rest against the door and support all
of the spring tension. Stretch the spring 1/4 towards the edge of the door to
create clearance between the spring coils, allowing for smooth operation.
Tighten the set screws on the winding cone to 14 -15 ft.-lbs. of torque. Care-
fully push the upper bar toward the ceiling just enough to free the lower bar,
then SLOWLY remove the upper bar. If required, repeat for the other side.
IMPORTANT! Pushing the upper bar too far will cause the counterbalance
cables to fall off the cable drums.
Hold the door down to prevent it from rising unexpectedly, in the event the
spring(s) were overwound, and carefully remove the locking pliers from the
vertical tracks. Raise the door until the top section and half of the next section
are in a horizontal position. Do not raise door any further since rear of hori-
zontal track is not yet supported.
WARNING!
RAISING DOOR FURTHER CAN RESULT IN DOOR FALLING AND
CAUSE SEVERE INJURY OR DEATH.
Now clamp a pair of locking pliers to the vertical tracks just above the second
roller on one side, and just below the second roller on the other side. This will
prevent the door from raising or lowering while installing the rear support.
