Labels
Single duct terminals units are shipped from the factory with the following information labels.
1) Sample Nameplate Label
– affixed to the air terminal casing beside the control mounting panel. Shows tagging information, serial-model number, size, cfm, voltage,
amps, MOP, etc.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection as described in the job specification. The
diameter of the inlet duct for round inlets (unit size 4 through 10)
must be equal to the listed size of the terminal. The inlet collar of
the terminal is made 1/8" (3) smaller than listed size in order to fit
inside the duct (see figure 1). Unit size 12 through 16 utilize flat
oval inlet collars and unit size 24 x 16 has a rectangular inlet collar.
The flat oval inlets are undersized for flexible duct connection. For
hard inlet duct connections, refer to submittal drawing for
dimensional data. On exhaust units the duct should mate to the
terminal using slip and drive connections (see Fig. 4).
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.
The outlet end of the terminal is designed for use with slip and drive
duct connections. A rectangular duct the size of the terminal outlet
should be attached.
Field Wiring
All field wiring must comply with NEC and local codes. Electrical,
control, and piping diagrams can be found on labels affixed to the
exterior/interior of the control enclosure box. All Nailor electric
heaters are staged per specifications. The installing electrician
should rotate the incoming electric service by phase to help
balance the building electric load.
IMPORTANT: Electric re-heat units ordered with SCR or
SSR, route field wiring near bottom of control box. Do not
place directly behind SCR or SSR.
Fuse size designates the size of the internal fuse if it is supplied.
Maximum Overcurrent Protection (MOP) designates the largest
breaker or fuse in the electrical service panel that can be used to
protect the unit.
Control Start-up and Operation
Your local Nailor Representative can provide detailed information
about start-up and operating procedures for Nailor’s digital, analog,
and pneumatic controls. For specific information on controls
provided by other manufacturers, contact the specific
manufacturer’s local or national office. This applies whether the
controls were factory or field mounted.
Note: Digital controllers may use specific communication addresses
based on Building Management Systems Architecture and original
engineering drawings. Installing the terminal in a location other than
that noted on the label may result in excessive start-up labor.
