MODEL T OPERATOR APPLICATIONS

Drawbar operators are intended for commercial and industrial use on sectional overhead

doors which use horizontal track with normal radius. A drawbar operator is not suitable for

doors with high lift or vertical lift doors. The installation requires a minimum clearance of 8

inches above the highest point of the door at any point in its travel. Please refer to Figure 10

for back room requirements.

A drawbar operator - when properly installed - will eectively lock the door in the closed

position.

PRODUCT FEATURES

Before starting the installation of the

operator, the door must be in good

working condition, properly operating,

and be properly counterbalanced. Inspect

the door and track for loose or missing

hardware. Test the door manually for

balance and ease of operation. Lubricate

door hinges and rollers. If necessary,

employ a qualied technician to adjust

the springs for proper counterbalance of

the door.

Before removing the operator powerhead

from the shipping carton, inspect the

nameplate on the cover of the operator

control box to verify that it is the correct

model for the intended application,

and that the voltage and phase are

in accordance with electrical power

provided at the job site. The rails are

shipped separately from the powerhead.

Model T Drawbar operators are used in the following applications:

• Continuous Duty, Indoor Commercial installations only

• Up to 22 foot high doors with a maximum area of 480 square feet for 3/4HP, 360 square

feet for 1/2HP, and 270 square feet for 1/3HP. Maximum area slightly higher for lighter

doors - consult factory.

• Use with reversing door edge or photoelectric device - REQUIRED where the 3-button

station is out of sight of the door, or any other automatic, remote, or manual control is

used to activate the door.

OPTIONAL FEATURES:

Digital Radio Controls: Open, Close and Stop operation. Radio units are available to control

up to 27 doors from one transmitter.

Keyless Entry System: Connection terminals provided for hard wired or wireless keyless

entry systems.

• Install only on a properly balanced garage door. An improperly balanced door could

cause severe injury. Have a qualied service person make repairs to cables, spring

assemblies, and other hardware before installing the opener.

• Remove all ropes, and remove or make inoperative all locks that are connected

to the garage door before installing the opener (unless mechanically and/or

electrically interlocked to the power unit).

• Lightweight doors (berglass, aluminum etc.) must be reinforced to avoid door

damage. Check the door manufacturer’s instruction manual for a bracing procedure

or the availability of a Reinforcement Kit.

• PowerMaster Model T Drawbar operators are Commercial Vehicular Door Operators,

and as such, are NOT recommended for pedestrian trac. In installations where it

is known that the pedestrians will be nearby, ensure a pedestrian door is available

for entrance and exit to the building. In addition, YOU MUST install an auxiliary

entrapment protection device (reversing door edge or photoelectric beam device)

as part of the compete operator system.

• Connect an auxiliary entrapment protection device (reversing edge or photoelectric

device across the door opening). A device of this type is STRONGLY ADVISED FOR

ALL commercial operator installations. An auxiliary entrapment protection device

is REQUIRED when the three button control station is out of sight of the door or any

other automatic or manual control is used.

• Install the opener AT LEAST 8 feet or more above the oor.

• Do not connect the opener to the source of power until instructed to do so.

• Locate the control station:

a. Within sight of the door;

b. At a minimum height of 5 feet above the oor so small children cannot reach it;

and

c. Away from the door, so the user is prevented from coming in contact with the

door while operating the controls.

• Do not overtighten the clutch adjustment to compensate for a poorly working door.

• Securely attach any WARNING signs or placards to either the door or above the

control station as directed.

• After installing the opener, all safety features must be tested for proper operation.
