Fan Powered Terminals VAV Terminals
Receiving Inspection
After unpacking the terminal, check it for
shipping damage. If any shipping
damage is found, report it immediately
to the delivering carrier. Store units in a
clean dry location and do not stack more
than four high.
Also, inspect damper rotation of the unit
by rotating the damper by hand to check
for free movement, and ensure there is
no damage or binding of the damper. If
controls are connected to the damper,
release the manual clutch (most controls
are equipped with this) and rotate the
damper by hand. If there is any
restriction to the rotation of the damper,
contact your Titus rep and inform them
of this issue.
Caution: Do not use the inlet collar,
damper shaft, flow sensor or air
tubing as a handle to lift or move
assembly. Damage to the unit or
controls may result.
Before installation, remove fan packing
and all foreign material from the unit.
Check the blower wheel for free rotation.
Supporting the Assembly
Suspend the unit from the building
structure in a horizontal plane with the
access panels facing downward.
Do not obstruct the access panels
with support channels or straps.
One inch long sheet metal screws can
be used to penetrate the casing (see
Figure 1). Use the support method
prescribed for the rectangular duct on
the job specifications. Unit may be
equipped with optional hanging brackets
(see Figure 2). Hanger rod up to 7/16"
diameter may be used.
Any flexible conduate shall be supported
per UL 1995 section 20.12, national
electric code, and any state and local
codes having juristiction
Note: If equipped with pneumatic
controls, or unit is parallel fan type
(Model TQP or FLP), the terminal must
be mounted right side up. It must be
level within ±10 degrees of horizontal,
both parallel to the air flow and at the
right angle of air flow. The control side of
the terminal is labeled with an arrow
indicating UP.
Duct Connections
Slip each inlet duct over the inlet collar
of the terminal. Fasten and seal the
connection by the method prescribed by
the job specification. The diameter of the
inlet duct “D” in inches must be equal to
the listed size of the terminal; e.g. a duct
that actually measures 8 inches must be
fitted to a size 8 terminal. The inlet collar
of the terminal is made 1/8" smaller than
listed size in order to fit inside the duct
(see Figure 1).
Important: Do not insert duct work
inside the inlet collar of the
assembly.
Inlet duct should be installed in
accordance with SMACNA guidelines.
Rectangular discharge opening is
designed for flanged duct connections.
Fasten and seal by method prescribed
in the job specification.
If single-point electronic velocity sensor
is used, 3 to 5 inlet duct diameters of
straight duct should be provided at the
terminal inlet.
Minimum Access
Fan Powered terminals require sufficient
clearance to service the fan blower
assembly and internal actuator (if so
equipped) from the bottom of the unit,
low voltage controls from the side of the
unit, and line voltage motor controls or
electric heat section (if so equipped)
from the rear or discharge of the unit.
For bottom access panel removal, 3"
minimum vertical clearance below the
unit is required, plus sufficient horizontal
clearance to slide the access panel clear
of the bottom of the unit. Horizontal
clearance is dependent on access panel
dimensions as indicated on product
submittals.
For low voltage control enclosure
access, a minimum of 18" is
recommended. Specific control
enclosure location is indicated on
product submittals. Panel for low voltage
enclosures are removable (not hinged).
For line voltage motor controls or electric
heat control access, a minimum of 36"
should be provided to allow full opening
of hinged access doors. Specific location
is indicated on product submittals.
Important: These recommendations
do not preclude NEC or local codes
that may be applicable, which are
the responsibility of the installing
contractor.
