SAFETY SYMBOLS
The following symbols are used in this document to alert the reader to areas of potential hazard:
DANGER indicates an imminently
hazardous situation which, if not
avoided, will result in death or serious
injury.
WARNING indicates a potentially
hazardous situation which, if not
avoided, could result in death or se-
rious injury.
SAFETY CONSIDERATIONS
The equipment covered in this manual is designed for
safe and reliable operation when installed and operated
within its’ design specication limits. To avoid personal
injury or damage to equipment or property while
installing or operating this equipment, it is essential
that qualied, experience personnel familiar with local
codes and regulations, perform these functions using
good judgment and safe practices. See the following
cautionary statements.
ELECTRICAL SHOCK HAZARDS
All power must be disconnected prior
to installation and servicing this equip-
ment. More then one source of power
may be present. Disconnect all power
sources to avoid electrocution or shock
hazards.
HOT PARTS HAZARD
Electric resistance heating elements
must be disconnected prior to servicing. Electric heaters may start auto-
matically; disconnect all power and
control circuits prior to servicing to
avoid burns.
Check that rigging and lifting equipment can safely support the unit as-
sembly and component weights.
CAUTION identies a hazard which
could lead to damage to the machine,
damage to other equipment and/or
environmental pollution. Usually an
instruction will be given, together with
a brief explanation.
NOTE is used to highlight additional
information which may be helpful to
you.
All assemblies must be adequately
secured during lifting and rigging by
temporary supports and restraints un-
til equipment is permanently fastened
and set in its’ nal location.
All unit temporary and permanent
supports must be capable of safely
supporting the equipment’s weight and
any additional live, seismic or dead
loads that may be encountered. All
supports must be designed to meet ap-
plicable local codes and ordinances.
All fastening devices must be designed
to mechanically lock the assembly in
place without the capability of loosen-
ing or breaking away due to system
operation and vibration.
Secure all dampers when servicing
damper, actuators or linkage. Dampers may activate automatically, discon-
nect the control circuits or pneumatic
control systems to avoid injury.
Protect adjacent ammable material
when brazing. Use ame and heat
protection barriers where needed.
Have re extinguisher ready for im-
mediate use.

INSPECTION
Upon receipt of equipment, carefully check all items
against the bill of lading to ensure that all equipment has
been received (including shipped loose items). Note any
discrepancy on the bill of lading before signing.
Inspect all equipment for any signs of damage caused
during transit. On units with re-heat, check the coil
ns and/or ensure that the resistance heat coils are
not damaged. Note any visual damage on the bill of
lading before signing. Immediately report all visual
and concealed damage to the carrier and le a claim
with the carrier.
Locate the model number on the nameplate and check
that the correct units have been received. Verify that all
options have been included, such as controls, heating
coils, etc. Also ensure that unit voltage agrees with the
building parameters. If a discrepancy is discovered
between what was ordered and received, contact your
local Johnson Controls representative immediately.
DO NOT USE FLOW SENSOR,
CONNECTING TUBES, COIL STU-
BOUTS OR DAMPER SHAFT AS
A HANDLE WHEN LIFTING OR
MOVING EQUIPMENT, AS DAM-
AGE MAY OCCUR.
DO NOT HANDLE EQUIPMENT’S
HEATING ELEMENTS, AS PERMA-
NENT DAMAGE MAY OCCUR.
DO NOT work on damper until associ-
ated actuator is disconnected.
NEVER pressurize equipment above
specied test pressure.
PROTECT adjacent ammable ma-
terials when brazing. Use ame and
heat protection barriers where needed.
Have a re extinguisher at hand and
ready for immediate use.
STORAGE
If equipment is to be stored prior to installation, observe
the following precautions:
1. Choose a dry storage site that is reasonably level
and sturdy to prevent undue stress or permanent
damage to the equipment. Set equipment off
ground if in moisture prone areas.
2. Tag and store in a safe place until needed. Cover
entire equipment with protective tarp or moisture
proof cover. Extend cover under equipment if
stored on ground. Secure cover with adequate tie
downs and store indoors. Be sure that piping connections have protective shipping caps installed.
CHECK assembly and component
weights to be sure that the rigging
equipment can handle them safely.
Note; also check the centers of gravity
and any specic rigging instructions.
CHECK for adequate ventilation
so fumes do not migrate through
ductwork to occupied spaces when
welding or cutting around the unit.

PRE-INSTALLATION INSPECTION
DO NOT USE FLOW SENSOR,
CONNECTING TUBES, COIL STU-
BOUTS OR DAMPER SHAFT AS
A HANDLE WHEN LIFTING OR
MOVING EQUIPMENT, AS DAM-
AGE MAY OCCUR.
DO NOT HANDLE EQUIPMENT’S
HEATING ELEMENTS, AS PERMA-
NENT DAMAGE MAY OCCUR.
Ensure that all linkages are connected properly. Check
the linkage that connects the actuator to the damper shaft
to ensure that the nuts are tight.
While viewing the damper from the discharge of the
unit, rotate the shaft fully. The damper should close
fully and there should be no gaps between the damper
gasketing and the inside of the valve.

All terminal equipment with electric heaters must
be installed in a horizontal plane with respect to the
airow stream. Low height equipment (Model TSL)
can be ipped over in the eld to vary or change control
section handing.

SEQUENCE OF OPERATION
Single Duct
The basic unit consists of a sheet metal casing and an air
valve, which is used to modulate the air being delivered
into the occupied zone. Air enters the air valve inlet
and exits into the sheet metal casing to be distributed
to the occupied zone through ductwork attached to the
discharge of the unit.
The basic unit can be ordered with either a factory
mounted hot water heating coil or an electric heater.
These re-heat units are used primarily to reheat the
air-to-zone temperature when the load in the occupied
space drops off.
The primary air is modulated through the FlowStar™
air valve by rotating the damper blade. The air valves
come in rectangular and round. The round valves only
come in diameters of 4, 5, 6, 8, 10, 12, 14 and 16 inches;
an adapter must be used for metric ductwork.
All equipment covered in this document, including those
with electric heat, are ETL listed for 0.0" clearance to
combustibles. Refer to NEC and/or local codes for
minimum electrical clearances required for service.
Equipment should not make contact with any structure
located above the equipment without appropriate
isolation. Equipment supplied with bottom access
panels requires sufcient clearance to access fasteners,
and to lower and slide panel horizontally until clear of
bottom of unit.
Hanging and Mounting Equipment
Although the basic equipment is generally light enough
that it can be supported by the ductwork, Johnson
Controls strongly recommends that all equipment be
suspended from the upper most ceiling or a structural
element of the building, independent of the false ceiling
grid. Suspension devises are eld supplied, sized and
designed by others. Johnson Controls will not accept
responsibility for unit support. Equipment must be
installed in a level horizontal plane. Failure to level
equipment properly may prevent proper operation of
controls. Provisions for proper support in seismically
active regions is the responsibility of others. See table
1 through 4 for unit weights.
