DISENGAGEMENT
1. To operate door manually, pull both disconnect
chains and lock off in bracket. This will
release the brake and engage the chain hoist.
2. Disconnect the hand chain from its bracket
and pull on hand chain to raise the door. Use
caution to ensure you are pulling the correct
direction.
3. Raise door approximately one foot and release
the hand chain. The door should stay in this
position. If it does not, there may be a problem
with the door. Do not operate it manually.
Contact your local Raynor Distributor for repair.
4. To return to electrical operation, disengage
disconnect chains and lock hand chain into
bracket.
INSTALL MOUNTING PAD
Begin installation by locating operator mounting pad in
position shown (See Fig. 2). Use steel plate or heavy
wood securely fastened to wall or framework.
HANGING OPERATOR
During installation, keep in mind that it is best to have
both the driving sprocket on the operator, and the driven
sprocket on the door shaft, as close as possible to the
bearings that hold the shafts in place. Assemble large,
driven sprocket to door shaft as shown in Fig. 3 using
the key provided in hardware package and tighten set
screw. If door shafting is tubing, it should be plugged
with 3/4" dia. solid bar for best results.
Place small drive sprocket on proper side of operator shaft as
shown in Fig. 3. Remove base mounting plate from operator
(see Fig. 3) and use as a template for drilling holes in wall, then
re-install base mounting plate to operator. Lift operator into place,
raising it so that the mounting bolts are against the bottom of the
slots in the base angle to allow for maximum chain adjustment.
Snug bolts enough to hold operator in place. The small drive
sprocket will need to be aligned with large driven sprocket. Loosen
set screw and move small sprocket along shaft to align vertically
with large sprocket on door shaft. See Fig. 3. Place chain over
door sprocket and operator sprocket. If chain is too long, remove
required number of links and reassemble. Loosen mounting bolts
and lower the operator to take up slack in chain. Be sure operator
drive shaft is level and tighten mounting bolts. To prevent operator
from moving out of position, install two bolts in horizontal
slots of base angle. At this point, check all bolts and set screws for
tightness.
INSTALL DISCONNECT BRACKET
The operators are furnished with floor operated disconnect
mechanisms to allow manual operation of door in an emergency.
A wall mounted bracket is supplied with each operator to lock
the disconnect chain in position while manually raising or lowering
door. A length of chain with an extension spring is provided for
use on standard side mounted units (position 1 and 5). Mount
the bracket directly below the operator and thread the chain
through slot in bracket. Best results are obtained when the
cable travels a minimum distance in a straight line.
