Receiving Inspection
After unpacking the terminal unit, 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.
Caution: Do not use the inlet collar, damper shaft, airflow
sensor, electrical conduit, or tubing as a handle to lift or move
assembly. Damage to the air terminal unit or controls may
result.
Supporting the Assembly
Suspend the unit from the building structure in a horizontal plane.
Be careful not to obstruct all the access panels with support
channels or straps. When requested, unit is supplied with field
mounted hanger brackets for use with hanger rod up to 3/8" (9.5)
dia. Hanger brackets or straps should be screwed to the top corner
posts, unit casing sides or alternatively onto the inlet and outlet
ends of the unit if the top corner posts are not accessible. Fan
powered VAV terminal units are too heavy to suspend with the
ductwork. They must be independently supported.
Nailor recommends attaching straps or screws into the 16 gauge
frame of the 35S and 35P Series units for mounting when possible
as shown in the figures below.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection by the method prescribed in the job
specification. The diameter of the inlet duct in inches must be equal

to the nominal size of the terminal inlet. The inlet collar of the
terminal is 1/8" (3) smaller than the nominal duct size to allow it to
fit inside the duct. Important: Do not insert ductwork inside the
inlet collar of the assembly. For optimum performance, 2 to 3
equivalent diameters of straight duct should be installed prior to the
inlet of the unit. All ducts should be installed in accordance with
SMACNA guidelines. Rectangular discharge opening is designed
for a flanged duct connection. A clear area around the opening has
been left for screw penetration. Fasten and seal all connections by
method prescribed in the job specification.
Minimum Access
Make appropriate accommodations for access panel removal.
Nailor 35S and 35P fan powered VAV terminal units have access
panels on the top, bottom and sides. Nailor 35N units have only
bottom panels. Model 37S has top and bottom panels. Model 38S
has only top panels (or bottom panel if the 38S 1 is oriented for
ceiling use). For low voltage control enclosure access, a minimum
of 18" (457) is recommended. Specific control enclosure location is
indicated on product submittals. Low voltage control enclosures
have removable covers that are attached with sheet metal screws.
High voltage controls enclosures have access panels that are
equipped with hinges. For clearances for full opening of hinged
access doors, refer to project specifications, submittal sheets and
NEC.
Important: These recommendations do not preclude NEC or
local codes that may be in effect, which are the responsibility
of the installing contractor.
