IMPORTANT SAFETY NOTES
The force, as measured on the closing edge of
the door, should not exceed 150 N (15kg). If the
closing force is adjusted to more than 150 N,
additional entrapment protection devices must
be installed, see page #9 for matrix. Do not use
the force adjustments to compensate for a binding or sticking door. Excessive force will interfere
with the proper operation of the Safety Reverse
System or damage the door.
Fasten the caution label adjacent to the door con-
trol station as a reminder of safe operating procedures.
Disengage all existing door locks to avoid damage
to door. If the door lock needs to remain functional,
install an interlock switch.
Install the three button station, master disconnect switch and any additional controls in a
location where the door is visible, but out of the
reach of children. Do not allow children to operate push button(s) or remote control(s). Serious
personal injury from a closing door may result from
misuse of the opener.
CAUTION: Activate opener only when the door
is in full view, free of obstructions and opener is
properly adjusted. No one should enter or exit
through the door opening while the door is in
motion. Do not allow children to play near the
door.
Proper electrical lock-out/tag-out procedures
must be followed before making repairs or
removing covers on the door operator.
Keep door balanced. Sticking or binding doors
must be repaired. Doors, door springs, cables, pulleys, brackets and hardware are under extreme tension and can cause serious personal injury. Do not
attempt to loosen, move or adjust them. Call for
door service.

SITE PREPARATIONS
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,
with the drive shaft parallel to the door shaft.
The safety and life of the operator will be adversely
affected if any of the above requirements are not met.
For metal buildings, fasten 50mm x 50mm x 5mm (2”
x 2” x 3/16”) (or larger) angle iron frames to the building purlins. Retain 140mm (5-1/2”) between frames.
See Figure 3.
Both EJ and EH series operators have dual output
shafts and may be mounted on either the right (standard) or left side of door, and in either a vertical (standard) or horizontal mounting position. If you need to
move the drive sprocket, loosen BOTH set screws,
remove the sprocket and key, and place on the opposite side of the drive shaft. Be sure to tighten BOTH
set screws securely
Hand Chain Handing
For model EH with manual hoist hand chain systems,
the handing of the operator must be determined at the
time of order. The handing is indicated by last letter of
the model name (R or L). The hand chain wheel can
not be switched on site. If your installation causes
the hand chain to hang in the door opening, hook the
chain off to the side near the top of the door jamb.
OPERATOR PREPARATION
140mm
(5-1/2”)
Door Requirements: Door must be balanced within 150N and must have mechanical fixed stops at the end

The weight of this operator powerhead is excessive, and can cause severe injury upon lifting, installing
or dislodging from its mounted position.
The operator powerhead should be raised into its mounting position by use of a hoist or elevated platform. Acceptable lifting points are output shaft or chassis frame. Do not lift by electrical enclosure. The
unit should be secured to the lifting apparatus to prevent it from swaying or dislodging during installation. The unit should be fastened to its mounting surface with the correct size and grade hardware. All
mounting hardware should be securely fastened before releasing supporting devices. (See figure 4 on
page 6 for proper lifting).
The above stated procedures must be followed in the event that the unit is to be removed from
its mounted position when servicing is required.

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 305-380mm
(12 - 15”). Refer to Figure 5.
OPERATOR MOUNTING
IMPORTANT:
The shelf or bracket must provide adequate support, prevent play between operator and door
shaft, and permit operator to be fastened securely, 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 305-380mm (12 - 15”).
Refer to Figure 6.
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. Align sprockets and tighten all set screws and
mounting hardware. (see Figure 7).

These operators are equipped with a manual hoist. An
electrical interlock will disable the electrical controls
when the hoist is used. To operate the hoist:
1. Pull the disconnect chain (small chain) to engage the
hoist mechanism. The disconnect chain may be locked
in position by slipping the end through the keyhole of
the chain keeper mounted on the wall.
2. Operate the door in the desired direction by pulling
on one side or the other of the continuous loop hoist
chain (large chain).
3. The disconnect chain must be released from the
chain keeper before the door will operate again electrically.
7. Install Hand Chain (Model EH) Place hand
chain around hand chain wheel. Be sure to pass
it through both openings in the chain guide.
Remove enough links so chain hangs approximately 609mm (24”) above the floor.
EMERGENCY MANUAL OPERATION
This operator has provisions for manually operating the door in case of an emergency or power failure. Refer to
the appropriate instructions below for your model operator.
Model EH
Model EJ
This operator has a floor level disconnect chain to disconnect the door from the door operator. An electrical
interlock will disable the electrical controls when the
operator is disengaged.
1. To disengage, pull the chain and secure in the dis-
engaged position by slipping the end through the keyhole bracket mounted on the wall. Or if emergency
egress device is used, pull handle to disengage operator from door.
2. The door may now be pushed up or pulled down
manually. Release the disconnect chain to operate the
door again electrically.
