PREPARATION
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 5-1/2" (13.97 cm) between frames.
The GH operator may be mounted on either the right (standard)
or left side of door, and in either a vertical (standard) or
horizontal mounting position. Refer to the steps below if you
require the hand chain and/or disconnect chain to be on the
opposite side of the operator; or if the operator is being mounted
in a horizontal position.
HAND CHAIN RIGHT/LEFT CONVERSION
Remove the two snap rings (1 piece outer, 1 piece inner) on hand
chain shaft assembly. Position roll-pin to fit through cutout in
frame and slide complete shaft assembly through housing and
bevel gear. Insert shaft assembly on opposite side of housing,
and replace bevel gear, bearing, hardware, and snap rings on the
opposite side of shaft in the same manner.
DISCONNECT LEVER RIGHT/LEFT CONVERSION
Remove cotterpins on the ends of the disconnect shaft (square
shaft), move the disconnect lever arm to the opposite side, and
replace the cotterpins. Be sure to keep (2) 12 gauge washers on
the side without the lever arm.
HORIZONTAL MOUNTING CONVERSION
Remove cotterpins on the ends of the disconnect shaft (square
shaft), and remove lever. Replace lever using square hole on
opposite end of lever. Reposition sash chain to opposite end of
lever also. Replace cotterpins.
To prevent possible SERIOUS INJURY or DEATH:
• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an
interlock switch.
• ALWAYS call a trained professional door serviceman if door
binds, sticks or is out of balance. An unbalanced door may
not reverse when required.
• NEVER try to loosen, move or adjust doors, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension and can cause SERIOUS personal
INJURY.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.

CONTROL STATION WIRING AND INSTALLATION
CONTROL WIRING CONNECTIONS
1. Connect control wires to the P1 terminal block located on the
logic board as shown.
2. Connect conduit with all control wires through the conduit
hole in the electrical box enclosure marked with the label
shown below.
3. Apply power to the operator. Press OPEN push button and
observe direction of door travel and then Press the STOP
button.
If door did not move in the correct direction, check for improper
wiring at the control station or between operator and control
station. NOTE: In “Diag” mode the 3-button control station can be
tested to verify correct wiring of Open, Close and Stop buttons
without moving the door.
If the door moves in the wrong direction and or the limits move
in the wrong direction, simply move the motor direction jumper
located on the logic board from the factory default setting (STD)
to the (REV) pins. This will change the motor rotation as well as
the functional position of the OPEN and CLOSE limit switch’s.
Then relocate the safety limit switch (SLS) only to the opposite
side with the new functional close limit location. Orient the arm
(lever) of the limit switch away from the center. NOTE: The motor
direction change is not available on the DJ and DH models.
EXTERNAL RADIO WIRING CONNECTIONS
On all models a radio terminal bracket marked R1 R2 R3 is
located on the outside of the electrical enclosure. In B2 mode the
operator will then open a fully closed door, close a fully open
door, stop an opening door, and reverse a closing door from the
radio remote. In TS control wiring the operator will only open the
door or reset the timer to close. However, for additional door
control from a 3-button remote, a commercial three-channel radio
receiver (with connections for OPEN/CLOSE/STOP) is
recommended.
NOTE: If an external radio receiver is being used in place of the
built-in receiver, remove or disconnect the coaxial cable from the
logic board.
MOUNTING INSTRUCTIONS
1. Mount WARNING NOTICE beside or below the control station.
2. Mount MAINTENANCE ALERT label to either side of control
station.
3. Mount control station(s) within line of sight of door(s).
