1A. Installation Sequence Continued
Step 6:
Insert slide arm rod into slide arm tube setting the distance
between the pinion square and the slide stud at 13-1/2”
(343). Install 9/64” hex drive socket head screw from screw
pack. (See illustration below)
Step 7:
Using an adjustable wrench, rotate pinion 45° toward hinge,
as shown below. With the arm assembly parallel to the
door, secure arm to pinion when square of the pinion aligns
with the square in the arm. Secure with countersunk
washer and 1/4-20 Flat Head Screw (with thread lock)
provided. Tighten screw with 7/16” wrench or socket.
Step 8:
Insert arm stud into slide block in track assembly. Secure by
pushing in on the retainer clip that extends from the slide
block in the track, until it is flush with the slide block (see
illustration below).
Step 9:
Adjust closing power of unit (See Fig. 1) - Using a 1/8” allen
wrench, turn the power adjustment shaft clockwise
to
increase door closing power. Door control is shipped set at
midpoint of power setting. Maximum closing power can be
achieved with 8 (360°) clockwise turns of the power
adjustment screw.
Step 10:
Adjust Hydraulic valves using a 1/8” hex wrench to obtain
proper door closing speeds. See following illustrations.
Refer to Table 1 below for recommended minimum opening /
closing times per ANSI/BHMA A156.19.
Closing Cycle – Make adjustments, as necessary, to the Sweep Speed
"S" valve and Latch Speed "L" valve. See Fig. 2 below for
location of valves. Turn valves clockwise to reduce speed,
counter clockwise to increase speed.
Opening Cycle – Adjust Backcheck, "B" valve, as
necessary, for hydraulic resistance to door opening in the
backcheck range. See illustration in Fig. 2 for location of
valve.
NOTE: Too much Backcheck, "B" valve, can affect
t
he
operation of the units pump, preventing units from
fully opening the door. This valve may require fine
tuning after all other adjustments have been made.
Note: A.D.A. requires that from an open position of
70°, the door will take at least 3 seconds to move to a
point 3” (75mm) from the latched position
,
measured
at the leading edge of the door.
Step 11:
Make wiring connections using Wiring Instructions on Page 7.

Table 1 - Minimum Opening / Closing Times for ANSI/BHMA A156.19
Backcheck - adjust the backcheck valve to have a
minimum opening time to backcheck or 80 degrees
(whichever comes first) based on Table 1.
Closing Time - adjust Latch and Sweep valves to have a
minimum closing time from 90 degrees to Latch Check or
10 degrees (whichever comes first) based on Table 1.
