An incorrectly installed or improperly
adjusted door closer can cause property
damage or personal injury. These instructions
should be followed to avoid the possibility
of misapplication or misadjustment.
CAUTION
!

!
!
Always use template covering door-opening-angle desired,
correct door-thickness and frame-reveal, and door-hanging-
hardware being used. Template dimensions in these
instructions (page 2) cover frame reveals to 7-3/8” (187mm)
in opening with 1-3/4” (44mm) thick doors hung on 4-1/2”
(114mm) wide template-hinges (figure 2), 3/4” (19mm)
offset-pivots (figure 2) or center-pivots (figure 3).
Check hand of door: right or left (see figure 5, page 3). Make
sure that door opens the full angle desired and latches
without any binding action or interference. Note that hold-
open units will require that door swing five (5) degrees past
hold-open point, to dead-stop position.
It is suggested that sex-nuts and bolts be used to mount
arm-foot and to mount closer to flush partitions.
Top Jamb Unitrols are supplied with arm rod units according
to frame-reveal. An arm number is stamped on the arm
rods, as shown on Figures 2 and 3 (page 2).
UNI Stop/Holder
The closing force for these series door
closers is adjustable from a size 1 to a size 6,
as outlined in ANSI Standard A156.4. When
these series of door closers are installed and
adjusted to conform to ADA reduced opening
force requirements (5 lbs max.) for interior
doors, they may not have adequate closing
force to reliably close and latch the door. Power adjustments
charted on Page 4 are recommended where possible, to
ensure proper door control.
