HLO-1050 Linkage Kit
Installation Guide
INTRODUCTION
Install an HLO-1050 Linkage Kit for a KMC
Conquest Airflow Measurement System (AFMS)
on units with vertical-axis damper blades. The
linkages transfer the damper motion to a surface
with a horizontal axis, on which the AFMS
controller's inclinometer can then be mounted.
Mount the kit's damper blade crankarm on a
damper blade or on a jackshaft using the included
jackshaft coupler and V-bolt. If unable to mount
the kit's axle mount shaft to the damper frame, use
a VTD-0903 right-angle bracket (sold separately).
See the KMC Conquest AFMS Installation Guide
— found on any AFMS controller's product page —
for installation of other AFMS components.

NOTE: For dampers with jackshafts, use the
included jackshaft coupler
15
and
V-bolt
16
to fasten the crankarm to the
jackshaft. (See Figure D on the next
page.)
3. Rotate the damper blades to the 45° position.
4. If possible, temporarily attach the axle mount
shaft
7
to the damper frame using a vise grip
or clamp to allow for adjustments.
ASSEMBLING
1. Place the inclinometer crankarm
9
onto the
axle mount shaft
7
using the shaft retainer
assemblies
12
, the thrust washer bearing
13
and the flanged bearing
14
. (See Figure C.)
2. Loosely fasten the ball joints
5
to the
inclinometer crankarm
9
, the damper blade
crankarm
1
and the drive shaft
6
.
(See Figures A and C.)
NOTE: With damper blades at the 45° position,
the inclinometer crankarm
9
should
be vertical and positioned on the axle
mount shaft
7
so that the drive shaft
6
is level and parallel with the face of
the damper frame. (See Figs. A and C.)
MOUNTING
1. Select a location on the damper that will allow
the linkages to move freely throughout the
damper blade rotation.
NOTE: Typically the damper blade crankarm
1
mounts onto the second damper
blade.
2. Fasten the damper blade crankarm
1
to the
damper blade with two ¼"-28 hex head screws
2
or
3
, and two ¼"-28 lock nuts
4
.
(See Figures A and B.)
NOTE: For damper blades with offset profiles,
use the included spacer
17
to make
the damper blade crankarm
1
flush
with the damper blade. (See Figure B.)

2. Loosen clamp and adjust position if necessary.
NOTE: For optimal results, the axle mount
shaft
7
should be positioned so that
the drive shaft
6
is horizontal when
the damper blades are at the 45°
position.
3. Adjust the two ball joints
5
along each slot
in either crankarm as needed to increase or
decrease the linkage kit's range of motion.
4. If binding occurs when opening or closing the
damper, adjust the distance between the ball
joints
5
along the drive shaft
6
.
5. If the drive shaft
6
collides with any one of
the damper blades, move the inclinometer
crankarm
9
along the axle mount shaft
7
to
increase blade clearance.
NOTE: Moving the ball joint
5
along the slot
in the damper blade crankarm
1
can
help this process as well.
6. Repeat steps 1 to 5 as needed.
TIGHTENING
Once calibration is complete:
1. Fasten the axle mount shaft
7
to the damper
frame with two #10-32 TEK screws
8
.
NOTE: If unable to mount the axle mount
shaft
7
to the damper frame (because
of mounting inside a duct), use a
VTD-0903 right-angle bracket (sold
separately) and the screws shown in
Figures F and G on the next page.
2. Tighten the fasteners on the ball joints
5
and
the shaft retainer assemblies
12
.
NOTE: The shaft retainer assemblies
12
must be placed tightly against the
inclinometer crankarm
9
to prevent
side-to-side play.
3. Fasten the inclinometer (sold with controller)
onto the inclinometer crankarm
9
with two
#8-32 Phillips pan head screws
10
and two
#8-32 lock nuts
11
. (See Figs A and C.)

CALIBRATING
Calibration of the system for optimal performance
is necessary. Keep in mind that the target range of
motion for the inclinometer crankarm
9
is 90°
when moving the damper from fully open to fully
closed. (See Figure E.)
1. Open and close the damper fully to test the
linkage kit's range of motion.
NOTE: With the damper at 45° the
inclinometer crankarm
9
should be
vertical (as shown in Figure A) and
should travel roughly the same amount
of degrees when opening and closing
(per Figure E).
