Accessory Installation
NOTICE: Unit accessories may
be larger than unit intake and
discharge opening or flanges.
Due to infinite installation
possibilities, a section of
ductwork or transition may be
required for proper accessory
mounting (by others).
IMPORTANT: Installer
MUST
SUPPORT
accessory items from
a rigid point or points to ensure
solid mounting using field or
factory supplied hardware.
DESIGN CONSIDERATION:
Titan Air strongly recommends
using a flex coupler between the
AMU and Ductwork.
Refer to Field Wiring section, under the
installation section, for instructions on wiring the
damper actuators.
Design Requirement: If an intake hood is
supplied by others, the design shall minimize
entry of snow/ rain and include an intake screen
to meet ANSI standards.
Accessories on large equipment may be
shipped in two pieces for field assembly. As a
result, two damper actuators may need to be
field wired.
