ASSEMBLY INSTRUCTIONS FOR MOTORIZING

AR or AW Single and Double Panel Dampers

Final assembly of the motor operating mechanism on AR or AW damper may be accomplished by the following
instructions:

1. Attach the Motor to the Motor Base as shown in
Figure 1 using four 5/32” x 3/8” bolts. Do not
tighten bolts.

TABLE 1

AR&AW

SIZE

11-17
18-82

2. Remove all springs supplied on the unmotorized
version and discard. Flatten the spring tab to the
position shown in Fig. 5.

3. Place the motor assembly as shown in Fig. 2 for
double panel damper and Fig. 3 for a single panel
damper.

LENGTH TO

REMOVE

5.75"

Use Spring As Is

4. Mark the locations of the (3) holes in the motor base
on the flange.

5. Drill 11/64” (.172) dia. hole at each of the positions
marked.

6. Place the motorizing AR damper spacer between
the motor base and flange as shown in Figure 5.

7. Mount the motor assembly to the damper using
three No. 8 sheet metal screws marked “A” in
Figures2&3.

8. Attach the spring, supplied in the motorizing kit, to
the operator and the spring tab opposite the motor
as shown in Fig. 3. Refer to Table 1 for length.

9. Slide the Motor in the Motor Base slots toward the
center of the Damper. Rotate the motor arm to the
position shown in Fig. 1, 2 & 3.

10.Connect the Motor Chain Link to the Motor Arm at
the furthest position (position A in Fig. 6) from the
Pivot Point. Remove a sufficient number of links
from the Connecting Chains such that as much
slack as possible is removed when installed. Install
the Connecting Chain from the Operator to the
Motor by hooking the end of the Connecting Chain
into the hole in the Operator. Close the end link

around the Operator. Slide the Motor away from the
center of the damper until all slack is removed from the
Connecting Chain. Tighten Motor Mounting Bolts
thoroughly. Take care to maintain the 8 inch dimension
as shown in Figures 2 and 3.

Your damper is now ready to operate.

NOTE: The Damper Motors on this product
are stall type motors which are designed to
run continuously, in a stalled condition, when
the damper is open.

NOTE: If dampers do not open fully, the
connection between the Motor Arm and Motor
Chain Link can be slid towards the Pivot Point
(Fig. 6), to supply more torque to the operator.

NOTE: If this motorizing kit is to be used in an
application requiring 460 volt single phase
current, then a 115 volt Damper Motor and a
460 volt to 115 volt Step-Down Transformer
will be supplied and should be wired as shown
in Figure 4.
