NOTE:
•
Make necessary mechanical adjustments so
unit functions as a standard surface mounted
door closer before adjusting spring force,
applying power, adding accessories or making
electrical/programming adjustments.
•
Refer to table for recommended minimum
opening/closing times per ANSI/BHMA
A156.19. (Figure 13)
•
Use provided 1/8" hex wrench to make

full open to 10°.
• Valve "L" controls Latch Range from
10° to closed.
2.
Opening Cycle (Figure 12)
• Valve "BC" controls strength of cushioning in
Backcheck Range.
NOTE: Too much backcheck can affect
operation of unit pump, preventing full
open of door. This valve may require fine
tuning after all other adjustments have been
made.
B. Adjust spring force.
NOTE:
•
The amount of effort to manually open or
close a door is called force and is controlled by
the operator's closer spring.
•
Make necessary mechanical adjustments
described in "A" above.
•
A closer set to ADA required 5 lbs opening
force may not be strong enough to close door
due to latching hardware, air pressure, or
frame issues.
1.
Using 1/8" hex wrench, turn power adjustment
screw clockwise to increase door closing power.
(Figure 14)
