Step 3— Install Components
INSTALL INFINITY DAMPER CONTROL — The Infinity
Damper Control is designed so that wires can enter it from behind,
above, or below. Plan wire routing before mounting Damper
Control.
1. Remove cover to access mounting holes.
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
INSTALL ZONING USER INTERFACE — (see Infinity Zone
Control Installation Instructions for details).
NOTE: Improper wiring of the ABCD connector will cause the
Infinity Zoning System to operate improperly. Check to make sure
all wiring is correct before proceeding with installation or turning
on power.
INSTALL REMOTE ROOM SENSORS —
1. Separate the sensor cover and mounting back plate by squeez-
ing the top and bottom of the cover together firmly by
grasping the raised top and bottom ridges. This will release the
cover. Mount to wall using provided screws and anchors.
2. Pull a 2-conductor wire through hole on right-hand side.
3. Recommended connection is BLACK to either terminal,
WHITE to remaining terminal (sensor terminals are not
marked for polarity because polarity is not important).
Stranded or common bell wire may be used. Lengths up to
1000 ft. will contribute no noticeable error.
4. Push any extra wire into wall and seal hole to prevent air
leaks. Align sensor cover with base plate then press firmly
until cover snaps into place.
INSTALL ZONING SMART SENSOR — See Infinity Zoning
Smart Sensor Installation Instructions for details.
Step 4— INSTALL ZONE DAMPERS
Proper selection and sizing of dampers is very important for proper
system operation. Be sure to consult the Damper Product Data
Digest for assistance in making these selections. Selection and
sizing information is not provided in this installation instruction.
Zone dampers are available in round, rectangular, and slip-in
design and may be installed in any position. Install dampers so that
actuator is visible for inspection and accessible in the event it
would need to be serviced. The black mark on the end of the
damper shaft represents position of damper blade. To wire damper,
locate terminals labeled: OPN (open); COM (common); CLS
(closed; and wire appropriately (see Fig. 1 for Damper 24 VAC
connection).
If duct system requires multiple dampers for a single zone, up to
5 dampers (maximum) may be wired in parallel. For all applica-
tions, including retrofit, it is recommended to use only current
dampers with direct-drive style actuators. DO NOT use older
damper with crank-arm style actuators.
If an actuator is removed from a damper for any reason, it must be
properly aligned when it is reinstalled. This can be done by
rotating the actuator and the blade to their closed positions and
then tightening the actuator (set screw) to the shaft. This assures
alignment at the closed position. (Pressing the quick blade release
button allows the actuator to be manually turned).
ELECTRICAL OPERATION HAZARD
Failure to follow this caution will result in euipment damage
or improper operation.
Condensation can damage the actuator. When dampers are
located in an unconditioned space, condensation is likely to
occur in cooling. To prevent condensation and losses, all
dampers and ductwork in unconditioned space must be
insulated or otherwise protected.
Whenever condensation might occur, it is recommended that a
plastic actuator cover (p/n, DAMPACTXXCOV) be used over the
actuator. These covers can help prevent condensation on actuators
by locking out ambient humidity. Insulation may be applied over
the cover to minimize heat transfer.
To install, place the cover over actuator and seal in place over the
surrounding insulation with duct tape on all four sides. Sealing
need not be perfect because there will be positive pressure inside
the cover. Do not mount the dampers with their actuators hanging
directly beneath the ductwork. It is best to mount the actuator
facing in either the three or nine o'clock position.
For specific duct types, follow instructions below:
NOTE: All zone dampers and ductwork must be properly sup-
ported according to local codes or SMACNA standards.
ROUND METAL DUCTWORK
1. Crimp end of branch duct.
2. Slip end of zone damper over end of ductwork. Use self-
tapping sheet metal screw to secure.
3. Properly seal joint using duct tape, mastic, or other approved
method. Do not allow mastic to come in contact with actuator.
4. If dampers are applied in an unconditioned space, insulate
damper using 1-1/2 inch to 2 inch insulation (See Fig. 2).
RECTANGULAR DUCTWORK
1. Make connections using S-lock and drives (See Fig. 3).
2. Properly seal joint using duct tape, mastic, or other approved
method. Do not allow mastic to come in contact with actuator.
3. If dampers are applied in an unconditioned space, insulate
damper using 1-1/2 inch to 2 inch insulation (See Fig. 4).
ROUND FLEXIBLE DUCTWORK
1. Slip one end of flexible ductwork over end of zone damper
(See Fig. 5).
2. Secure flexible duct to zone damper using SMACNA or other
approved method.
3. Properly seal joint using duct tape, mastic, or other approved
method. Do not allow mastic to come in contact with actuator.
4. If dampers are applied in an unconditioned space, insulate
damper using 1-1/2 inch to 2 inch insulation (See Fig. 6).
RECTANGULAR FIBROUS GLASS DUCTWORK
1. Insert one end of zone damper into end of fibrous glass
ductwork approximately 2 to 3 inches (See Fig. 7).
2. Use field supplied screws to secure duct board to zone
damper.
3. Properly seal joint using duct tape, mastic, or other approved
method. Do not allow mastic to come in contact with actuator.
4. If dampers are applied in an unconditioned space, insulate
damper using 1-1/2 inch to 2 inch insulation (See Fig. 8).
