ION Damper Control Installation And Start-Up Instructions Manual page 3

Step 3 — Install Components
INSTALL IONt DAMPER CONTROL
The Iont 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 IONt SYSTEM CONTROL
See the Iont System Control Installation Instructions for details.
NOTE: Improper wiring of the communications connector will
cause the Iont 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
squeezing the top and bottom of the cover together firmly
by grasping the raised top and bottom ridges. This will re-
lease the cover. Mount to the wall using the screws and an-
chors provided.
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 the wall and seal the hole to pre-
vent air leaks. Align the sensor cover with the base plate,
then press firmly until the cover snaps into place.
Step 4 — Install Zone Dampers
NOTE: Only use modulating dampers provided by ICP for use
with the Ion Zoning System. Dampers provided by other
companies are NOT compatible with the Ion Zoning System.
Proper selection and sizing of dampers is very important for proper
system operation. Be sure to consult the Iont System Control
Product Data Sheet and Iont Zoning Design Guide 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, except, avoid placing the actuator directly below the
ductwork if condensation on or within the duct is expected. Install
the damper so that the 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 the position of the
damper blade. To wire the damper, locate the terminals labeled:
OPN (open); COM (common); CLS (closed; and wire
appropriately (see Fig. 1 for Damper 24 VAC connection).

If the duct system requires multiple dampers for a single zone, up
to five dampers (maximum) may be wired in parallel. DO NOT
use dampers 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.)
CAUTION
!
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment 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.
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 the instructions below:
NOTE: All zone dampers and ductwork must be properly
supported according to local codes or SMACNA standards.
ROUND METAL DUCTWORK
1. Crimp the end of the branch duct.
2. Slip the end of the zone damper over the ductwork end. Use
a self- -tapping sheet metal screw to secure.
3. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
4. If dampers are applied in an unconditioned space, insulate
them using 1- -1/2 inch to 2 inch insulation (See Fig. 2).
