D635 Zone Dampers

NOTES:
1. Install the motor in any location except where acid
fumes or other harmful vapors might attack the metal
parts of the actuator or in atmospheres of escaping
gas or other explosive vapors.
2. Choose a location for the damper/actuator that al-
lows enough clearance for servicing (Fig. 46).
3. Mount the ML6161 Actuator with the motor shaft in
any position so the motor is flush with the damper
housing. Failure to do so can cause unbalanced gear
wear and result in premature failure. In the event the
motor cannot be mounted flush against the damper
housing, add a spacer or washer between the mount-
ing tab and the damper housing.
Install the D635 Damper as follows:
1. Cut and remove enough ductwork into which the
damper can be inserted.

2. Insert and secure the damper into the ductwork.
NOTE: The damper must be kept at the full 90
setting for proper system operation.
3. Wire the ML6161 Actuator as shown in the job
drawings and Fig. 47.
WARNING
Disconnect power supply before wiring to pre-
vent electrical shock or equipment damage.
NOTES:
1. All wiring must comply with local electrical codes,
ordinances and regulations.
2. The voltage and frequency of the transformer used
with the ML6161 must correspond to the characteris-
tics of the power supply and motor.

CAUTION
1. To prevent damage to the damper or keep it
from moving through its full range, do not
distort the damper shape, or put screws or
anything else into the damper.
2. Ensure the high limit setting is 200 F [93 C]
or lower. Higher settings can damage the
electric actuator.
NOTES:
1. Install AOBD and AOBD-BM dampers in squared
air ducts. Frame misalignment jams damper blades.
2. Secure AOBD and AOBD-BM dampers by inserting
screws in the sides of the damper, not on the top or
bottom.
