Fan Powered Terminal Units IOM
INITIAL INSPECTION
Once items have been removed from packing, check
carefully for damage to duct connections, coils, or controls.
File damage claims immediately with transportation agency
and notify Krueger.
NOTE: Remove all packaging material and foreign
material from unit and ensure the blower wheel moves
freely before installation. Every fan terminal unit is
shipped with cardboard ring in one side of the fan inlet
that MUST be removed. This ring is accessible from the
unit’s plenum.
UNIT IDENTIFICATION
Each unit has 2 main labels attached to the casing. The
FAN UNIT label (Figure 3) lists the model number, supply
voltage requirements, motor horsepower and overcurrent
protection requirements. The AIRFLOW label (Figure 4)
lists the model number, unit size, factory order number
and location. The location “tag” indicates where the unit is
intended for installation. There may be other labels attached
to the unit, as options or codes may require. Read all labels
on a typical unit before attempting installation. Control
boxes are assembled as indicated on the identication label.
Contact your local Krueger representative for more
information.

CONTROL OPTIONS
The units are oered with a wide variety of factory-mounted
controls that regulate the volume of air delivery from the
unit and respond to cooling and heating load requirements
of the conditioned space. All control packages can operate
stand-alone and will fulll the thermal requirements of a
given control space. These devices are available in both
pneumatic and electronic arrangements. A number of DDC
control packages by others are available for consignment
mounting as indicated. Each control approach oers a
variety of operating functions; a control package number
identies combinations of control functions. Because of the
variety of functions available, circuit diagrams, operating
sequences, and function descriptions are contained in
separate Application Data publications. These publications
are available from the Krueger website, www.krueger-hvac.
