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.
1. To operate door manually, with door in closed
position, pull disconnect chain and lock off in
bracket, this will release the transmission and
allow the door to be operated manually.
2. Do not stand or walk under the door while door
is moving
3. Manually raise door approximately one foot
and release. 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 chain.
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. Drill holes in mounting pad to fit location of
vertical slots in base angles of operator. Use cardboard
template found in operator packaging for drilling rather than
transferring dimensions. 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 is provided for use on standard side
mounted units (position 1 and 5).
Note: On operators with chain
hoist, two disconnect chains are provided. One chain with
extension spring disengages the brake mechanism and the other
chain engages the chain hoist. See figures 4 and 5 for directions.
Mount the bracket directly below the operator and thread
the chain through slot in bracket. If the operator is mounted in
any position other than 1 or 5, it may not be possible to use
the chain provided. In such a case, use aircraft cable and
pulleys to result in a smooth working disconnect. Best results
are obtained when the cable travels a minimum distance in a
straight line.
