4 Opening Speed Adjustment
- L NOTE: For air pressure regulation, see control box instructions.
- 4a The door opening speed must be adjusted to suit the width and weight of 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 speed to open door from 0° to 80° for the time shown in the table below. The opening speed control adjusting screw is located in the end of the door operator near the tubing connection (see Figure 2). Using a C\cx" allen wrench (provided), turn the speed control clockwise to slow the door, counter clockwise to increase speed.
| Door Weight in | FASTEST OPENINGTIME 0° to 80° | |||||
|---|---|---|---|---|---|---|
| Pounds | DOOR WIDTH IN INCHES | |||||
| 36" | 42" | 48" | ||||
| 100 lbs. | 3.0 sec | 3.5 sec | 4.0 sec | |||
| 125 lbs. | 3.5 sec | 4.0 sec | 4.5 sec | |||
| 150 lbs. |
3.5 sec
200 lbs. 4.0 sec |
4.5 sec | ||||
| 5.5 sec | ||||||
L NOTE: If door width or weight is between the sizes and pounds listed, use the time shown for the next wider or heavier door.
CAUTION
DO NOT SET DOOR SPEED FASTER THAN CHART RECOMMENDS.
4b 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 the table below.
| Type of Door | Weight per Sq. Ft. |
|---|---|
| - Solid Core Wood | 5.5 lbs |
| - 20 Ga.Flush Hollow Metal | |
| - Aluminum x Z\v" Glass | |
| - Mineral Core Door | 7.0 lbs |
| - 16 Ga.Flush Hollow Metal | |
| - Aluminum x 1" Glass |
L NOTE: These weights are for 1 C\v" thick doors. If the doors are thicker or thinner, consult door manufacturer for proper weight, or weigh the door.
5 Backcheck Adjustment
- 5a Backcheck slows the door swing as it approached full opening (see Figure 2 on page 2).
- 5b 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. DO NOT USE AN ABRUPT BACKCHECK.
6 Delay Time Adjustment
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) 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 handicap. Time cycle begins when switch or scanner is released.
7 Attach Cover
- 7a Slide cover insert into the top cutout in cover (see Figure 3).
- 7b Push cover over the operator assembly and against mounting plate.
- 7c Insert cover screws and tighten securely.

Minor stile of door, approximately 18" min. to 42" max. above adjustment can be obtained by using the telescoping arm as the floor. The decal location must be visible without follows (see Figure 4): interference from door trim, panic devices, etc. Shorten length of arm to decrease door opening. Clean area 6" x 6" where decals will be placed. 8b Lengthen arm to increase door opening. Apply one decal (item 17 on page 5) on each side of Loosen arm set screw and adjust arm to preferred door. Remove backing and "roll" onto door to avoid length. trapping air under decal. 9c Tighten arm set screw securely after adjustment. After arm adjustment is made, cycle door to insure that it is operating properly. AUTOMATIC
