4 Opening Speed Adjustment
LNOTE: 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 Table 3 on page 3. The opening speed control
adjusting screw is located in the end of the door
operator near the tubing connection (see gure 1).
Using a 3/32” allen wrench (provided), turn the speed
control clockwise to slow the door, counter clockwise
to increase speed.

LNOTE: 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 nding 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.
Type of Door Weight per Sq. Ft.
- Solid Core Wood
- 20 Ga.Flush Hollow Metal
- Aluminum x 1/4” Glass
5.5 lbs
- Mineral Core Door
- 16 Ga.Flush Hollow Metal
- Aluminum x 1” Glass
7.0 lbs
Table 4
LNOTE: These weights are for 1 3/4” thick doors. If the
doors are thicker or thinner, consult door manufacture for
proper weight or weigh the door.
5 Backcheck Adjustment
5a Backcheck slows the door swing as it approached full
opening (see gure 1 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
gure 4).
7b Push cover over the operator assembly and against
mounting plate.
7c Insert cover screws and tighten securely.
8 Locating The Caution/Automatic Door Decal
8a Local one decal on each side of the door near lock
stile of door, approximately 18” min. to 42” max. above
the oor. The decal location must be visible without
interference from door trim, panic devices, etc.
8b Clean area 6” x 6” where decals will be placed.
8c Apply one decal (item 17 on page 5) on each side of
door. Remove backing and “roll” onto door to avoid
trapping air under decal.
