6 Johnson Controls Unitary Products
Optional Head Pressure Control - For those applications
where mechanical cooling is required below 40°F, optional
low ambient operation allows compressor operation down to
0°F.
Easily Upgrade Motor Efficiency to Meet Tighter Codes -
Optional high efficiency motors help you make simple
upgrades to meet more demanding building and energy
codes.
Enhanced Filtration Options - Millennium gives designers the
flexibility to meet various IAQ requirements with a full range
of rigid and throwaway filters at different efficiency levels.
Vibration Isolation - The Millennium's neoprene mounts are
typically sufficient for most applications but when sound and
vibration transmission are a major concern, YORK offers 1"
and 2" isolation springs for even greater protection from sup-
ply air fan noise and vibration.
Corrosion Resistant Coils- Many industrial and seacoast
applications require enhanced protection from corrosive envi-
ronments.
Optional TechniCoated Coated Condenser and Evapo-
rator Coils - Many industrial and seacoast applications
require enhanced protection from corrosive environ-
ments. The special dipped phenolic coating process
provides a high level of protection for the exposed con-
denser coil.
Optional Copper-Copper Condenser and Evaporator
Coils - For corrosion resistance.
High Capacity Evaporator Coils - For those applications
which require slightly more capacity than offered by the stan-
dard Millennium product, YORK offers the option of higher
capacity evaporator coils, boosting cooling output without
increasing unit size. (30 & 40 Ton R-22 only)
Variety of Exhaust Air Options - YORK Millennium offers a
wide variety of exhaust air options, including barometric
relief, non-modulating power exhaust, and modulating power
exhaust. And, because Millennium units use forward-curved
blowers for power exhaust fans, they can exhaust up to 100%
of the nominal supply air at much greater static pressure
loads than competitive units. Not available on end return.
NOTE: In most applications, the supply fan will keep the
return at negative pressure. A barometric relief will
function better when ducted to building space, not
the return.
Optional Factory Installed Economizers - Millennium units
offer economizers with Standard or Optional low leak damp-
ers. Comparative enthalpy, single enthalpy and dry bulb con-
trol are available.
Optional Factory Installed Disconnect - A conveniently
located actuator handle in the front of the unit can disconnect
line power to the entire unit, eliminating the need for a field
provided disconnect. The handle may also be locked in either
position through the use of a standard padlock. Millennium's
single point power connection makes this option particularly
appealing. If desired, the disconnect may be ordered with a
115 volt, GFCI protected convenience outlet, including a fac-
tory wired transformer to power the outlet from the single
point power connection; the convenience outlet remains
operational when the disconnect is open.
Heating Done Your Way - Millennium offers the choice of nat-
ural gas standard or modulating gas heat, electric resistance
heat, hot water heat, steam, or no heat at all. Very simply, the
choice is yours.
INSTALLATION FEATURES
With YORK Millennium, high performance doesn't mean high
complexity. YORK listened carefully to make sure that Millen-
nium was as simple as possible, and service convenience
comes standard with each unit. From a single curb size to the
easy service access, you'll find that Millennium was designed
to be easy from start to finish.
Full Range of Air Flows and Static Pressures - The Millen-
nium design gives a complete offering of supply air flows and
static pressure combinations to meet most every application
requirement.
Single Power Point Connection - Millennium units have a sin-
gle gas and electric connection, minimizing time at the job
site. For further installation flexibility, power and gas connec-
tions may be brought up from the curb or through the side of
the unit.
Simple Controls - Millennium's controls system is easy to
understand and apply, and it doesn't lock you into proprietary
devices. A choice for YORK Millennium today does not limit
your choices tomorrow.
Rain Hoods Rotate Into Place - No bulky, field--installed rain
hoods here. Millennium rain hoods ship rotated inside the
unit. Once on the job, installer merely rotates the hood
upward and puts in a few screws - an easy one-person job.
Excellent Access for Service - Service access on Millennium
is a snap. Hinged and latched door options give access on
both sides of the unit to all major components. Some doors
have positive action slide latches for even greater ease of
access. All service fittings are conveniently located to mini-
mize time and effort.
