1a.
Wall Mounting
The operator should generally be installed below
the door shaft, and as close to the door as
possible. The optimum distance between the door
shaft and operator drive shaft is between 12” - 15”.
On concrete buildings, attach a shaft support
bracket to the wall of the building. Refer to Figure 3.
OPERATOR MOUNTING
IMPORTANT: An additional wall mounting
plate (P/N 10-9098) or equivalent is
recommended to provide additional support
and to allow for adjustment of the drive chain.
IMPORTANT: The shelf or bracket must
provide adequate support, prevent play
between operator and door shaft, and permit
operator to be fastened securely and with the
drive shaft parallel to the door shaft.
1b. Bracket or Shelf Mounting
The operator may be mounted either above or
below the door shaft. The optimum distance
between the door shaft and operator drive shaft is
between 12” - 15”. Refer to Figure 4.
1c. Place door sprocket on the door shaft. Do not
insert the key at this time.
2.
Place drive sprocket on the appropriate side of
the operator. Do not insert the key at this time.
3. Wrap drive chain around door sprocket and join
roller chain ends together with master link.
4.
Raise operator to approximate mounting position
and position chain over operator sprocket.
5.
Raise or lower operator until the chain is taut (not
tight). Make sure the operator output shaft is
parallel to door shaft and sprockets are aligned.
When in position, secure the operator to wall or
mounting bracket.
6.
