It is imperative that the wall or mounting surface provide adequate
support for the operator.

This surface must:

a. Be rigid to prevent play between operator and door shaft.
b. Provide a level base.
c. Permit the operator to be fastened securely and with the drive

shaft parallel to the door shaft.

The safety and wear of the operator will be adversely affected if
any of the above requirements are not met.

For metal buildings, fasten 2"x 2" x 3/16" (or larger) angle iron
frames to the building purlins. Retain 7" between frames.

To avoid damage to door and operator, make all door locks
inoperative. Secure lock(s) in “OPEN” position.

If the door lock needs to remain functional, install an interlock
switch.

DO NOT connect electric power until instructed to do so.

mounted or mounted on a bracket or shelf. If necessary, refer to the preparation on page 3. Refer to the instructions below that suit
your application.

INSTALLATION

OPERATOR MOUNTING

1. Wall Mount: The operator should generally be installed below

the door shaft, and as close to the door as possible (Figure 1).
Bracket or Shelf Mount: The operator may be mounted either
above or below the door shaft (Figure 2).

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.

NOTE: The optimum distance between the door shaft and operator
drive shaft is between 12" - 15".

2. Place door sprocket on the door shaft. Do not insert the key
at this time.

3. Place drive sprocket on the appropriate side of the operator.

4. Wrap drive chain around door sprocket and join roller chain
ends together with master link.

5. Raise operator to approximate mounting position and position
chain over operator sprocket.

6. 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.

7. Insert keys and align sprockets and secure (Figure 3).
