OPENING SPEED ADJUSTMENT
1. The door opening speed must be adjusted to suit the width and weight of the door. The wider and/or
heavier the door, the slower it should open. To determine opening speed, measure door leaf width
and weight and set set speed to open door from 0°to 80° for the time shown in Table 3 below. The
opening speed control adjusting screw is located in the end of the door operator near the tubing
connection (see figure 1). Using a 3/32" Allen wrench (provided), turn the speed control clockwise to
slow the door, counter-clockwise to increase speed.

After opening, the door should remain at the 90° position for no less than 5 seconds. This "Delay Time"
can be increased to approximately 30 seconds by turning the timer adjustment wheel(s) in the control box
clockwise. For the location of this wheel(s), refer to 7900 or 7980 Series Control Box Instruction Sheet.
Adjust "Delay Time" to maximum practical for the elderly or handicapped. Time cycle begins when switch
or scanner is activated.

Locate one decal on each side of door near lock stile of door, approximately 53" min. to 63" max. above
the floor. The decal location must be visible without interference from door trim, panic devices, etc.
Clean a 6" x 6" area where decals will be placed.
Apply one decal on each side of door. Remove backing and "roll" onto door to avoid

2. If door weight cannot be measured, the weight can be estimated by finding the area of the door
(length x width) and multiplying it by the weight per square feet for the door type that is being used as
shown in Table 4 below.
BACKCHECK ADJUSTMENT
1
2DO NOT USE AN ABRUPT
BACKCHECK.
. Backcheck slows the door swing as it approaches full opening (see figure 1 on page 2).
. Increase the resistance of backcheck only if necessary to prevent the door from striking a wall. To do
this, turn the regulating screw (nearest to hinge) clockwise by quarter turns.
NOTE:
These weights are for 1 " thick doors. If the doors are
thicker or thinner, consult door manufacture for proper
weight or weigh the door.
