Jackshaft Installation (JDC, RJDC, JHDC)
Determine Mounting Location
1.
The operator may be mounted on the wall, shelf,
or bracket (not provided, see "Accessories"
section. The optimum distance between the
door shaft and operator drive shaft is 12-15
inches (30.5-38 cm).
In the image, 1a shows the wall mount, and 1b shows
the shelf or bracket mount.
1a
Mount the Operator
The wall or mounting surface MUST provide adequate support for the operator. The surface must:
•
Be rigid to prevent play between the operator and the door shaft.
•
Provide a level base.
•
Permit the operator to be fastened securely and with the drive shaft parallel to the door shaft.
1.
Place the door sprocket on the door shaft so it can be moved to align vertically with the operator drive shaft.
2.
Insert the keys and fasten the sprockets with the set screws (recommended torque is 34-45 in-lb).
3.
Hold the operator in the desired mounting position so door sprocket and drive sprocket are vertically aligned.
4.
Mount the operator to the wall or mounting plate where the operator can be moved to aligned with the appropriate
hardware (not supplied).
5.
Wrap the drive chain around the door sprocket and the drive sprocket, then secure with the master link.
NOTE: Chain links may need to be removed to achieve appropriate chain length.
NOTE: It is highly recommended to add a thread adhesive to secure the set screws in place.
TO REDUCE THE RISK OF SEVERE INJURY:
•
NOTE: If the operator sprocket is below the minimum 8
foot height requirement, please install appropriate Chain
Guard Kit for your 2" output shaft (CHNGUARD) or 3"
output shaft (CHAINGUARD3IN). Chain Guard Kits are
sold separately.
