measureof a packaged rooftop’svalue.That’swhy
YORKeco2PackagedRooftopAirConditionersuse
establishedscroll-compressortechnologytodeliver
dependable, economical performance in a wide
range of applications. With the eco2Packaged
Rooftop, you get the latest generation of compres-
sor enhancements added to the scroll’s inherent
strengths. The simplicity of a hermetic scroll com-
pressor allows the use of fewer moving parts to
minimize breakdown. YORK also employs the lat-
estsealingtechnologyto avoid metal-to-metalcon-
tact.Axial sealing is accomplished with floating tip
seals, while radial sealing utilizes a microcushion
of oil. The result: a maintenance-free compressor
providing minimum wear and maximum runtime.
•Gas Furnace – The eco2rooftop gas furnace is an
induced-draft gas furnace designed for high effi-
ciency and reliability. The furnace uses an alumi-
nized steel tubular heat exchanger and operates
attemperaturessufficientto preventacidicexhaust
gases from condensing in the heat exchanger at
low fire rates, unlike drum and tube style furnaces
that generate condensation formation.
GasheatunitsareU.L./C.U.L.listedandare tested
to ANSI standard Z21.47. Multiple modules pro-
vide redundancy not available in single power
burner applications.
Serviceability
•OptiLogicTM – Fully-integrated factory-packaged
controls are standard on every unit and include a
display unit with a 4x20 character LCD display.
OptiLogicTM continuallymonitorsall control setpoints

LOCATION
Of the many factors that can affect the acoustical char-
acteristics of a rooftop installation, one of the most im-
portantis theunitlocation.Ideally, therooftopunit should
be installed away from sound-sensitive areas, such as
conference rooms, auditoriums and executive offices.
Possible locations could be above storage areas, hall-
ways, mechanical or utility rooms, or bathrooms.
The eco2air conditioning units are designed for out-
door installation. When selecting a site for installation,
be guided by the following conditions:
• Unit must be installed on a level surface.
• For the outdoor location of the unit, select a place
having a minimum sun exposure and an adequate
supply of fresh air for the condenser.
• Alsoavoid locations beneath windows or between
structures.
• Optional condenser coil protection should be used
forseashorelocationsorotherharsh environments.
• The unit should be installed on a roof that is struc-
turally strong enough to support the weight of the
unit with a minimum of deflection. It is recom-
mended that the unit(s) be installed not more than
15feetfromamainsupportbeamtoprovideproper
structuralsupportandtominimize the transmission
of sound and vibration. Ideally, the center of grav-
ity should be located over a structural support or
building column.
• Location of unit(s) should also be away from build-
ingfluestacksorexhaustventilatorsto prevent pos-
siblereintroductionof contaminatedairthroughthe
outside air intakes.
• Be sure the supporting structures will not obstruct
the duct, gas or wiring connections.
• Proper service clearance space of 6-feet around
the perimeter of the unit, 8-feet on one side for coil
servicing, and 12-feet to any adjacent units is re-
quired to eliminate cross contamination of exhaust
and outdoor air, and for maintenance tasks such
as coil pull and cleaning. No obstructions should
be above the condensing unit section.
RIGGING
Proper rigging and handling of the equipment is man-
datory during unloading and setting it into position to
retain warranty status.
Spreader bars must beusedbycranestoprevent dam-
agetotheunitcasing.Allliftinglugs must be used when
lifting the rooftop unit. Fork lifts will damage the rooftop
unit and are not recommended.
Care must be taken to keep the unit in the upright posi-
tionduring rigging and to preventdamagetothe water-
tight seams in the unit casing. Avoid unnecessary jar-
ring or rough handling.
Ground Level Locations
It is important that the units be installed on a substan-
tialbase that will notsettle,causingstrain on the refrig-
erant lines and sheet metal and resulting in possible
leaks.Aone-piece concreteslabwith footers extended
below the frost line is highly recommended. Addition-
ally, the slab should be isolated from the main building
foundation to prevent noise and vibration transmission
to the building structure.
For ground level installations, precautions should be
taken to protect the unit from tampering by, or injury to,
unauthorizedpersons.Erecting a fence around the unit
is common practice.
ECONOMIZER
The economizer section is used for ventilation of the
conditioned space to maintain indoor air quality, and
also to reduce energy consumption by using outdoor
air cooling in lieu of mechanical cooling. If outdoor air
isappropriate for cooling, but notsufficientfor the cool-
ing demand, mechanical cooling will stage on as nec-
essary until the cooling load is met.
Dual (comparative or differential) enthalpy operation is
the most accurate and efficient means of economizer
operation. The OptiLogicTM control monitors the return
and outside air energy content, and selects the lower of
the two for operation.
VAV SUPPLY AIR PRESSURE CONTROL
Traditional packaged rooftop systems use inlet guide
vanes (IGVs) for ductstaticpressure control.These con-
trol supply duct pressure by modulating dampers (intro-
ducing losses and inefficiencies) on the inlet of the fan,
open and closed. YORK’s variable frequency drives
(VFDs) offer superior fan speed control and quieter,
energy efficient operation.

FORM 100.50-EG3 (802)
9
YORK INTERNATIONAL
For VAV applications, the YORK eco2unit uses a VFD
to modulate fan speed and maintain a constant duct
static pressure. VFDs offer superior control over the
operation of the unit at part load, and offer the addi-
tional benefits of quieter and more efficient operation
when compared to IGV.
HARSH ENVIRONMENTS – CONDENSER AND
EVAPORATOR COIL PROTECTION
For harsh environmental conditions such as seashore
applications, YORK offers three types of coil protec-
tion: copper fin material, black fin and Technicoat coat-
ings. YORK recommends that for corrosive environ-
ments that copper fins be used to protect the evapora-
tor and/or condenser coils. In areas where chemicals
that can corrode copper are present, such as ammo-
nia,YORK recommends that the blackfinorTechnicoat
coating be used for maximum protection.
Copper Fin Condenser Coil
Copper fins can be used instead of aluminum for addi-
tional corrosion protection, however it is not suitable
for areas that are subject to acid rain or exposed to
ammonia.
Pre-Coated Condenser Fins
Black fin coating (yellow fin for evaporator fins) is pre-
coatedapplicationepoxyon aluminum finstocktoguard
fromcorrosiveagentsandinsulateagainstgalvanicpo-
tential. It is used for mild seashore or industrial loca-
tions.This can provide corrosionresistancecomparable
to copper fin coils in typical seashore locations.
Post-Coated Condenser Fins
Technicoat(apost-coated application of epoxy)canbe
usedforseashoreandothercorrosive applications with
the exception of strong alkaloides, oxidizers, wet bro-
mide, chlorine and fluorine in concentrations greater
than 100 ppm.
Any of the above suitable options should be selected
based on the particular project design parameters and
related environmental factors. The application should
befurtherreviewed and approved by the consulting en-
gineer or owner based on their knowledge of the job
site conditions.
BUILDING EXHAUST SYSTEMS
Building exhaust systems are often necessary when
economizers are used to bring in outdoor air. Without
properbuildingexhaust,thebuildingmaybecomeover-
pressurized. The exhaust system maintains the proper
building pressure by expelling the appropriate amount
of air from the building. Exhaust systems are typically
designed to exhaust approximately 10% less air than
whatisenteringthebuilding.Thisprovides a slight posi-
tive pressure in the building.
100% modulating exhaust with building static
pressure sensing and control
The 100% exhaust system can be configured with ei-
ther control actuated dampers or VFDs for modulating
control. The unit controller monitors the building pres-
sureusing a differential pressure transducer and main-
tains the required building static pressure by modulat-
ingthe exhaust control. Ifthebuildinghas other means
of exhaust or building pressure is not important, on/off
or barometric control may be used.
Powered exhaust with fan on/off control
The100% exhaust system canbeconfigured for on/off
operation eliminating the expense of the damper ac-
tuatorsorVFDs.Thisexhaustsystemcanbecontrolled
by either the outside air damper position, or a building
static pressure sensor.
Barometric exhaust
Barometricexhaustcanbeusedwhensmalleramounts
of air at low static pressure variations within the build-
ing or other means of building exhaust are employed.
Barometricexhaust is commonly usedwherethereare
only small fluctuations in building pressure or where
building static pressure control is not necessary.
ROOF CURB
YORK offers optional roof curbs designed specifically
for the eco2footprint. These curbs come disassembled
and require field assembly and installation. For bottom
supply and return openings, the curbs have matching
connections to ease installation. A pipe chase that
matches the rooftop unit pipe chase is also included in
thecurbfootprint forthrough-the-curbutilityconnections.

YORK INTERNATIONAL
10
The curb should be located according to the location
recommendations above, and properly sealed to pre-
vent moisture and air leakage into and out of the duct
system.Flexible collars should beusedwhenconnect-
ing the duct work to prevent unit noise transmission
and vibration into the building.
Duct work should be supported independently of the
unit.
ACOUSTICALCONSIDERATIONS
The eco2unit is designed for lower sound levels than
competitive units by using flexible fan connections, fan
spring isolators, double-wall construction, and lower
speed and horsepower fans. For VAV applications,
VFDs are used instead of inlet guide vanes.Additional
sound attenuation can be obtained using compressor
sound blankets and field-supplied sound attenuators
when necessary.
Evenwiththese equipment design features, the acous-
ticalcharacteristics of the entire installationmust never
beoverlooked.Additionalstepsforthe acoustical char-
acteristicsof a rooftopinstallationshouldbeaddressed
during the design phase of a project to avoid costly al-
terations after the installation of the equipment. During
the design phase of a project, the designing engineer
shouldconsider, at a minimum, theimpactof the equip-
mentlocation,rooftopinstallation,building structure,and
duct work.

Select Unit:
1. Determine the internal static pressure drop of the
cabinet by referencing Table 17.
Wet evaporator coil 0.58
Bottom return opening 0.15
Two-inch pleated filters 0.12
Mod. econ. dampers 0.56
Total 1.41 IWG
2. Determine the total static pressure by adding the
internal to the external static pressure.
TSP = 1.41 IWG + 2.25 IWG = 3.66 IWG total static pressure
3. DeterminetheBHPof thesupplyfan fromTable 15
using the supply air flow and total static pressure.
From the table, we interpolate to get 26.3 BHP at
724 rpm.
4. Determinethemotor heat gain of supplyairflowby
first calculating the motor energy and converting it
into Btuh.
Motor Energy
Motor kW = BHP x .746/efficiency
Motor kW = 26.3 x 0.746/0.94
Motor kW = 20.9 kW
Motor Heat Rejection (MHR)
MHR = 2545 x BHP/efficiency
MHR = 2545 x 26.3/0.94
MHR = 71.2 mbh
5. Calculate actual requiredtotalcooling capacity by
adding specified cooling capacity to motor heat
rejection.
Required Total Cooling Capacity
920 mbh + 71.3 mbh = 991 mbh
Required Sensible Cooling Capacity
610 mbh + 71.3 mbh = 681 mbh

6. Requiredtotalandsensiblecapacitiesare991mbh
and681mbh,respectively.The totalcapacityis82.6
tons, therefore a model YPAL085 is selected. Use
the Cooling Performance Data in Table 9. Locate
the table with the correct ambient air temperature.
Next, trace the 80°F entering air dry bulb tempera-
ture to match the 24,000 cfm and 67°F entering
wet bulb temperature condition. The resulting con-
ditions are, from the table, 996.5 mbh total cooling
capacity and 688.9 mbh sensible cooling capacity.
7. The high heat option for the YPAL085 provides
900 mbh of heat capacity with an input of 1,125
mbh. This is sufficient for the 875 mbh heating
requirement.
8. Determine net cooling and heating capacities if
required.
Net Cooling Capacity (NCC)
mbh = 996.5 mbh – 71.3 mbh
mbh = 925 mbh
Net Sensible Heat Capacity (NSHC)
mbh = 688.9 mbh - 71.3 mbh
mbh = 618 mbh
Net Heating Capacity (NHC)*
mbh = 875 mbh + 71.3 mbh
