STEP 1: HEADER BACKPL $ATE INSTALLATION
- Remove the header front cover by removing the 4 hex screws on the top & bottom of the operator.
- The motor assembly is factory mounted to the slotted back plate using FIVE hex bolts.
- The bolts attach to nuts that slide in the two slotted tracks of the back plate.
- The motor assembly should be removed before installing the housing backplate.
NOTE: When you order a PULL or PUSH operator, the motor assembly will be shipped from the factory in the appropriate PULL or PUSH orientation. Take note of the orientation before removing the motor assembly (i.e. Is the motor towards the center of the housing, or the edge of the housing)
To remove the motor assembly: First, remove the single hex bolt and washers located behind the transformer (a ball end hex wrench is recommended). Disconnect the ON‐Auto‐OFF connector from the board and unplug the molex main power connector.
Next, locate & loosen the 4 side hex bolts (see below). NOTE: One of the four hex bolts is fastened to the green ground wire of the power connector. This bolt will need to be removed temporarily to disconnect the green wire. Slide the bolts away from the motor assembly allowing the assembly to be removed.
Determine the handing of the door
The backplate will mount with the edge nearest the spindle cutout towards to the hinge
Mount the backplate to the top door frame using 5 or 6 of the screws provided, or use appropriate fasteners for the type of frame. Install reinforcement as required.
- Push side mounting: Bottom of the backplate is flush with bottom of the door frame. For hollow metal applications, drop 1/8”below the frame.
- Pull side mounting: Bottom of the backplate is mounted 1.5” up from bottom door frame.
- For a 36” opening, backplate should overlap each hinge jamb tube by 1.5”.
- Refer to the APPENDIX for fire rated door applications.
PUSH‐ARM APPLICATIONS: Bottom of operator header is flush with bottom of top frame.
NOTE: A 35 mm spindle adaptor is included with all standard push arm applications. This requires that the header assembly be mounted as shown at left, flush with bottom of frame face.
PULL ARM APPLICATIONS: Bottom of operator is mounted 1.5” up from the bottom side of top door frame Backplate should overlap hinge jamb tube by 1.5” (See figure below)
STEP 2: RE-MOUNT THE MOTOR ASSEMBLY
The orientation of the motor assembly will depend on the door handing & application (see below).
PUSH APPLICATION (I/O board towards the hinge)
Before reinstalling the motor, take notice of the location of the 4 mounting hex bolts, and the nut for the 5th mounting bolt
- Place and Hold the motor assembly up to the header, allowing it rest on the slotted tracks.
- Slide in the 4 outer hex bolts and tighten loosely. Slide the entire assembly left or right to line up the 5th hex bolt nut with the mounting hole from the bolt removed on page 5 (near the transformer). Reinsert the hex bolt and washers removed on page 5.
- Temporarily remove one of the mounting hex bolts and washers from the I/O board side of the assembly to allow the ground wire ring connector to be reconnected.
- After all 5 hex bolts have been inserted, reposition the whole assembly so that the spindle attachment point is centered with the spindle cutout, as shown on the bottom of page 5. Secure the motor assembly by tightening all 5 hex bolts.
- Reconnect the ON‐Auto‐OFF connector to the I/O board and the molex main power connector.
STEP 3: INSTALL THE ARM ASSEMBLY – STANDARD APPLICATION
NOTE: All operator arms include a standard spindle as shown below. Arm assembly options are detailed on the next three pages. Proceed to Page 14 for arm installation instructions.
PUSH ARM FOR STANDARD PUSH APPLICATION FOR REVEALS UP TO 8”
PULL ARM FOR STANDARD PULL APPLICATION WITH 0” REVEAL
NOTE: FOR REVEALS > 0” BUT LESS THAN ½”, A SPACER (PROVIDED BY INSTALLER) MAY BE INSTALLED BEHIND THE SLIDE TRACK TO ACHIEVE A 0” REVEAL. FOR A PULL APPLICATION WITH A REVEAL GREATER THAN ½”, USE A DOUBLE EGRESS ARM WITH A 20mm SPINDLE.
DOUBLE EGRESS ARM FOR STANDARD DOUBLE EGRESS PAIR OF DOORS, OR FOR A PULL APPLICATION WITH A REVEALGREATER THAN ZERO INCHES
NOTE: AN 80mm SPINDLE IS INCLUDED WITH THE DOUBLE EGRESS ARM. THE 80mm SPINDLE SHOULD BE USED FOR DOUBLE EGRESS PAIR OF DOORS. FOR PULL APPLICATIONS WITH REVEALS > 0”, USE A DOUBLE EGRESS ARM WITH A 20mm SPINDLE (SOLD SEPARATELY).
