In this Manual, the words Danger, Warning, and Caution are used to stress important safety information. The word:
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in injury or property damage.
The word NOTE is used to indicate important steps to be followed or important considerations.
IMPORTANT
READ PRIOR TO ANY DOOR OPERATION
POTENTIAL HAZARD EFFECT PREVENTION
Do Not operate unless the doorway is in sight and free of
obstructions. Keep people clear of opening while door is moving.
Do Not allow children to play with the door operator.
Do Not change operator control to momentary contact unless an
external reversing means is installed.
Do Not operate a door that jams or one that has a broken spring
Could result in
Serious Injury
or Death
Turn off electrical power before removing operator cover.
When replacing the cover, make sure wires are not pinched or near
moving parts.
Operator must be electrically grounded.
Do Not try to remove, repair or adjust springs or anything to which
door spring parts are fastened, such as, wood block, steel bracket,
cable or any other structure or like item.
Repairs and adjustments must be made by a trained service

WARNING
MOVING DOOR
1. Read manual and warnings carefully.
2. Keep the door in good working condition.
Periodically lubricate all moving parts of
door.
3. If door has a sensing edge, check
operations monthly. Make any necessary
repairs to keep it functional.
4. AT LEAST twice a year, manually operate
door.
The Door should open and close freely. If it
does not, the door must be taken out of
service and a trained service representative
must correct the condition causing
the malfunction.
5. The Operator Motor is protected against
overheating by an internal thermal protector.
If the operator ceases to function because
motor protector has tripped, a trained service
technician may need to correct the condition
which caused the overheating. When motor
has cooled, thermal protector will
automatically reset and normal operation can
be resumed.
6. In case of power failure, the door can be
operated manually by pulling the release
cable to disconnect the operator drive system.
7. Keep instructions in a prominent location
near the pushbutton.

Job Site Issues to Consider/Concerns
The following list of items should be considered prior to selecting an operator for a given job site.
1-Available power supply.
2-Type of door.
3-Potential operator mounting obstructions. Items to consider include, but are not limited to: side room, room above door shaft, room below door shaft, available mounting
surface integrity, power supply location, and convenient chain hoist and release cable positioning.
4-Size of door for appropriate operator torque and door travel speed selection.
dustiness5-Operator mounting environment. Items to consider include operator location and dampness, and corrosiveness of the location.
6-Door activation needs/requirements. Examples include 3 button control stations, 1 button control stations, radio controls, pull cords, loop detectors, photoelectric controls,
key switches, etc. See “Entrapment Protection” section below.
7-Interlock switches are required under certain conditions for doors with pass doors and door locks. See page 5.5.
8-Accessory equipment. Examples are reversing edges and/or photocell beams (required for
doors set to operate as momentary contact,), auxiliary control relays, warning lights, etc.
WARNING: DO NOT apply line voltage until instructed to do so.
CAUTION:
Check working condition of door before installing the operator. Door must be free from sticking and binding. If equipped, deactivate
any door locking device(s). Door repairs and adjustments, including cables and spring assemblies MUST be made by a trained service
representative using proper tools and instructions.
Section 3:
Critical Installation Information
ENTRAPMENT PROTECTION
The installation of a fail safe external reversing device (such as a monitored reversing edge or photocell system, etc.) is required on all momentary contact electronically
operated commercial doors. If such a reversing device is not installed, the operator will revert to a constant contact control switch for operation (Closing only).
The Reversing Devices currently UL Approved with are:
MillerEdge ME, MT and series monitored edge sensors used in combination with Timer-Close Module P/N OPABTCX.S or OPAKMEIGX.S INTERFACE MODULE.
2) Series II Commercial Safe-T-Beam®, Monitored Photocells P/N OPAKPE.S.
3) Series II Commercial Safe-T-Beam®, Monitored Photocells P/N OPAKPEN4GX.S.
2) Residential Safe-T-Beam® Monitored Photocells from The Genie® Company, model OSTB-BX (P/N 38176R).

Note: Total door weight, and not the square footage, is the critical factor in selecting the proper operator.
Square footage measurements are based on "square doors." (Example=16' x 16')
NOTE: Doors that require special windloading and wide doors, normally require increased strutting (reinforcement). Strutting doors can significantly increase door
weight beyond weight shown. Consult Customer Service for the impact of wind load andstrutting on square foot limits.
NOTE: "PU-FIP" stands for "polyurethane, foamed-in-place." If no notation is present, insulation is "polystyrene, layed-iin-place."

INSTALLATION INSTRUCTIONS
WARNING
-To reduce the risk of severe injury or death:
1) READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2) Install only on a properly operating and balanced door. A door that is operating
improperly could cause severe injury. Have qualified service personnel make
repairs to cables, spring assemblies and other hardware before installing the operator.
3) Remove all pull ropes and remove,or make inoperative,all locks (unless mechanically
and/or electronically interlocked to the power unit) that are connected to the door
before installing the operator.
4) Install the door operator at least 8 feet above the floor if the operator has exposed
moving parts.
5) Do not connect the door operator to the power source until instructed to do so.
6) Locate the control station: (a) within sight of the door, (b) a minimum of 5 feet above
the floor so that small children cannot reach it, and (c) away from all moving parts
of the door.
7) Install the Entrapment Warning Placard next to the control station and in a
prominent location.
8) For products having a manual release, instruct the end user on the operation of the
manual release.
Track Spacers are factory installed.

3) Insert the carriage into the tracks as shown in Fig. 3.
NOTE: One end of the carriage has a notch (Detail A) which will be
used to locate the chain pin (Detail B).This end of the carriage faces
the front spreader bracket and away from the power unit.
4) Attach the front spreader bracket to the front of the operator
tracks with two (2) track bolts and two (2) locknuts (check hole
alignment before installing).
5) Position the idler pulley inside the track and insert the
3/8" x 4-1/2" clevis pin. Secure the clevis pin using the
hitch pin. Fig. 4.
NOTE: Track bolts MUST be installed
from inside the track.

6) Attach the chain guide assemblies to the drawbar tracks
using track bolts and locknuts. Fig. 5.
NOTE: Space chain guides evenly between operator and header. Doors
12 foot tall and under will use 2 chain guides. Doors over 12 feet will
require 3 chain guides.
NOTE: Verify that track bolts are properly seated in track. Failure to seat
bolts can cause carriage to bind in door track.
