FORM 100.50-NOM6 (1207)
Introduction
•
Factory Shrinkwrap – All eco 2 rooftop units
can be ordered from the factory with an optional
factory-fresh shrinkwrap pack ag ing. This elimi-
nates the contractors worries about dirt and debris
clogging up condenser coils or moisture leaking
into the air han dler on the units way to the job
site or rigging yard.
•
Demand Ventilation Option – Can be incorpo-
rated into the unit to improve indoor air quality
and help manage indoor pollutants such as CO
2
or other harmful air borne con tam i nates out of
the occupied spaces for maximum comfort and
safety. Activation of this se quence can easily be
ac com plished using a CO
2
sensor installed in the
conditioned space. CO2 sensors are typically
used with de mand ventilation; however other
sensors may be applied to control indoor con-
tam i nants such as volatile or gan ic com pounds
(VOCs).
•
Smoke Purge – Is also available to evacuate
smoke due to fi re from a room or zone.
•
Filtration – The eco 2 is confi gured for various
types of fi ltration to meet the different needs and
re quire ments of today's rooftop applications,
including 2-inch throwaway, pleated, carbon,
and cleanable fi l ters and 12-inch high effi ciency
rigid fi lters.
ELECTRICAL
•
Single Point Power – The eco 2 unit comes stan-
dard with single point power connections to make
in stal la tion quick and easy.
•
Dual Point Power – Can be factory installed for
ap pli ca tions that require the mechanical heating
and cooling functions to be separated from the
air han dling functions. This enables the unit to
be op er at ed in an emergency condition while
minimizing power consumption.
•
Unit-Mounted Disconnect – Is available as an
op tion to minimize time at installation of equip-
ment and to reduce necessary field installed
items.

easy access into the unit for routine maintenance
and inspection.

re quir ing power tools, an optional 110V GFCI
pow er supply can power lights, drills or any other
power hand tool needed.
•
Factory Run-Tested – Each unit is subjected
to a series of quality assurance checks as well
as an au to mat ed quality control process before
being run-tested. Fans and drives are balanced
at the fac to ry during testing. The factory run-test
ensures safe proper operation when the unit is
installed, and reduces installation and commis-
sioning time.

checked.
