Features and Benefits
QUALITY ROOFTOP UNIT DESIGNED T O TODA Y’S
STANDARDS
Ecological and Economical Design
• First packaged RTU that meets ASHRAE 90.1-2001
with both R-22 and R-407C Refrigerants.
• Cooling and Heating – Superior operating performance provides lower operating costs. Smaller steps
of cooling capacity provide tighter control of building
environment and occupant comfort while optimizing
energy efficiency .
• Indoor Air Quality (IAQ) – Outside air economizer
provides energy savings in free cooling mode, and
can provide a healthier and more comfortable building environment by introducing fresh outside air into
the building as needed. Indoor Air Quality (IAQ) requirements for building ventilation and comfort are
controlled through the microprocessor control panel.
Optional air flow measurement provides an accurate
means of tracking air quality and alerting the occupants or building owner to unhealthy situations.
• Premium Efficiency – Premium-efficiency motors
are available for optimum energy efficiency. All motors used on the eco2 packaged rooftop air conditioner meet U.S. EP ACT 1992 minimum requirements.
• VFDs Standard on V A V Units – V ariable-frequencydrives provide the HVAC designer with a high-efficiency, quiet and more reliable means of variable air
volume control from a packaged rooftop. On larger
rooftops, ASHRAE 90.1-1999 st andard specifies part
load efficiency requirements that make VFDs the
cost-effective solution for meeting the standard.
VFDs can save the owner up to 40% of the energy
costs compared to inlet guide vanes offered on competitive units by reducing the power requirement.
VFDs use fewer parts, which leads to more reliability . Also, with fewer moving parts, and the reduction
of speed in the fan, the VFD operates at significantly
quieter operation than the inlet guide vane which
restricts a high volume of airflow, which can actually
increase noise at part load conditions.
Additionally, the YORK VFD includes DC link reactors as standard that have harmonic filtration comparable to an AC line reactor. VFDs also provide the
added benefit of soft-starting the supply fan, which
helps to minimize demand charges associated with
inrush currents.
• Network Connectivity with BACnet, LON or Roof-
Link Interface – Through optional communications
protocols, the eco2 rooftop unit can communicate to
any building automation system. There are four options available: BACnet Internet Protocol (Ethernet),
BACnet MSTP (RS485), LON or a generic RoofLink
BAS interface, depending on the type of building
automation system. Without network communications, the eco2 is designed to operate in stand-alone
mode, or via contact closures for basic control.
• Professional Appearance – A high quality powder
coat paint finish is applied to the galvanized steel
2
exterior of the eco
unit to protect it from aggressive
environments helping to maintain a factory-quality
appearance for years.
• FlexSys Underfloor Air System Configuration –
the eco
2
rooftop is the first packaged rooftop product
with designs specifically for use with the YORK FlexSys underfloor air system. Ask your local YORK
representative for more information.
Indoor Air Quality (IAQ)
• Double-Sloped Stainless Steel Drain Pan – This
double-sloped inclined stainless steel drain pan facilitates removal of evaporator condensate. Sloped
in two directions, this drain pan swiftly drains any
condensate from the unit. Best of all, the drain pan
is accessible for periodic cleaning required by IAQ
standards.
• Smart Ventilation – YORK maintains the leadership role in IAQ products with adaptive ventilation
control. The OptiLogic
TM
controls provide continuous
monitoring of air quality and take action by opening
the outside air dampers, bringing in the right amount
of fresh air before air impurities reach uncomfortable
or even dangerous levels.
• Air Flow Measurement – Precise measurement
of ventilation air flow is possible using an air flow
measurement station which can be installed in the
economizer section. Proper ventilation air flow is
required to ensure sufficient fresh air is in the building. A myriad of air flow measurement options are
available from minimum air flow to high-accuracy
full air flow capabilities. The complete system is designed as an integrated component of the
OptiLogicTM control system to ensure optimum system performance.
• Double Wall Construction – Rigid double-wall construction throughout provides ease of cleaning and
protects against insulation fiber entrainment in the
breathable air. Double-wall construction also helps
improve the acoustical characteristics of the air handling unit.
• Enhanced Filtration – The eco2 unit gives designers the flexibility to meet various IAQ requirements
with a full range of rigid and throwaway filter options
at various efficiency levels.
• Demand Ventilation – Control of the economizer
is available to maintain a desired ventilation level
based on a 0-10VDC input from a sensor . A factorysupplied CO2 sensor is available for installation in
the occupied space.

Reliable Cooling and Heating Technology
• Reliable, efficient, trouble-free operation is the true
measure of a packaged rooftop’s value. That’ s why
YORK eco2 Packaged Rooftop Air Conditioners use
established scroll-compressor technology to deliver
dependable, economical performance in a wide
range of applications. With the eco
2
Packaged
Rooftop, you get the latest generation of compressor enhancements added to the scroll’s inherent
strengths. The simplicity of a hermetic scroll compressor allows the use of fewer moving parts to
minimize breakdown. YORK also employs the latest sealing technology to avoid metal-to-metal contact. 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 eco2 rooftop gas furnace is an
induced-draft gas furnace designed for high efficiency and reliability. The furnace uses an aluminized steel tubular heat exchanger and operates
at temperatures sufficient to prevent acidic exhaust
gases from condensing in the heat exchanger at
low fire rates, unlike drum and tube style furnaces
that generate condensation formation.
Gas heat units are U.L./C.U.L. listed and are tested
to ANSI standard Z21.47. Multiple modules provide redundancy not available in single power
burner applications.
Serviceability
• Filter Maintenance Alarm – An optional filter maintenance alarm indicates when a filter becomes dirty
and requires replacement or cleaning.
Install with Ease and Safety
• Factory Run-T ested – Each unit is subjected to a
series of quality assurance checks as well as an
automated quality control process before being runtested. Fans and drives are balanced at the factory
during testing. The factory run-test ensures safe,
proper operation when the unit is installed and reduces installation and commissioning time.
• Single-Point Power Connection – Single-point
power connection reduces installation time by providing a single-point for incoming power, including
the optional convenience outlet. All incoming power
is connected in one location, reducing the cost of
distributed power wiring.
• Rain Hoods Rotate Into Place – No bulky , field- in-
stalled rain hoods here. eco2 rain hoods ship rotated
inside the unit. Once on the job, the installer merely
rotates the hood upward, caulks and fastens it in place
with sheet metal screws – an easy , one-person job.
• Factory-mounted and Wired Controls – All control points within the unit are factory-installed, wired
and tested.
• Non-Fused Disconnect – An optional factory-installed non-fused disconnect switch simplifies unit
installation and serviceability by eliminating the need
for a separate disconnect switch. Check local codes
for acceptability .
• OptiLogicTM – Fully-integrated factory-packaged
controls are standard on every unit and include a
display unit with a 4x20 character LCD display.
OptiLogicTM continually monitors all control setpoints
and configurations. If a unit sensor fails, the controller indicates an alarm. If desired, YORK service
can provide remote monitoring and automatically
schedule a service technician to make the repair
and maintain your comfort.
• Access Doors – Full-sized access doors provide
easy access into the unit for routine maintenance
and inspection.
• Suction & Discharge Service Valves – Oversized
service valves to provide isolation and quick reclamation and charging of system refrigerant are available to minimize downtime and simplify the service
and repair task.
• Convenience Outlet – For maintenance tasks requiring power tools, an optional 110V GFCI power
supply can power lights, drills or any other power
hand tool needed.
YORK INTERNATIONAL
Design Flexibility
• Low Ambient Operation – Head-pressure control
is accomplished via a VFD motor controller rather
than an inefficient and noisy condenser fan damper.
By varying the speed of the condenser fan, better
control and quieter operation is obtained during the
cooler weather. Low ambient controls are available
on all systems offering higher mechanical cooling
capacity at low ambient conditions than competitive units.
• Hot Gas Bypass – Optional on constant volume units,
hot gas bypass reduces the cycling of compressors
which helps prolong the life of the equipment.
• Duct Air Openings – Horizontal connections are
available on select configurations, offering more
flexibility for duct layout and improving sound transmission characteristics.
• Compressor Sound Blankets – For applications
in sound-sensitive areas, compressor sound blankets are available to reduce sound emitted from
the rooftop unit.

Features and Benefits (continued)
• Fan Spring Isolators – One-inch spring isolation
is used to prevent vibration transmission from the
rooftop unit’s supply fan to the building. Two-inch
spring isolation is also available.

Application Data
LOCATION
Of the many factors that can affect the acoustical characteristics of a rooftop installation, one of the most important is the unit location. Ideally , the rooftop unit should
be installed away from sound-sensitive areas, such as
conference rooms, auditoriums and executive offices.
Possible locations could be above storage areas, hallways, mechanical or utility rooms, or bathrooms.
The eco

be guided by the following conditions:
• Unit must be installed on a level surface.
• For the outdoor location of the unit, select a place
• Also avoid locations beneath windows or between
• Optional condenser coil protection should be used
• The unit should be installed on a roof that is struc-
• Location of unit(s) should also be away from build-

turally strong enough to support the weight of the
unit with a minimum of deflection. It is recommended that the unit(s) be installed not more than
15 feet from a main support beam to provide proper
structural support and to minimize the transmission
of sound and vibration. Ideally, the center of gravity should be located over a structural support or
building column.

the duct, gas or wiring connections.
the perimeter of the unit, 8-feet on one side for coil
servicing, and 12-feet to any adjacent units is required 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.
Spreader bars must be used by cranes to prevent damage to the unit casing. All lifting lugs must be used when
lifting the rooftop unit. Fork lifts will damage the roof top
unit and are not recommended.
Care must be taken to keep the unit in the upright position during rigging and to prevent damage to the watertight seams in the unit casing. Avoid unnecessary jarring or rough handling.
Ground Level Locations
It is important that the units be installed on a substantial base that will not settle, causing strain on the refrigerant lines and sheet metal and resulting in possible
leaks. A one-piece concrete slab with footers extended
below the frost line is highly recommended. Additionally , 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,
unauthorized persons. 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
is appropriate for cooling, but not sufficient for the cooling demand, mechanical cooling will stage on as necessary 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.
V AV SUPPLY AIR PRESSURE CONTROL
Traditional packaged rooftop systems use inlet guide
vanes (IGVs) for duct static pressure control. These control supply duct pressure by modulating dampers (introduc ing 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.
Proper rigging and handling of the equipment is mandatory during unloading and setting it into position to
retain warranty status.
8
YORK INTERNATIONAL
FORM 100.50-EG3 (802)
For V AV applications, the YORK eco2 unit 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 additional benefits of quieter and more efficient operation
when compared to IGV.
HARSH ENVIRONMENTS – CONDENSER AND
EV APORATOR COIL PROTECTION
For harsh environmental conditions such as seashore
applications, YORK offers three types of coil protection: copper fin material, black fin and Technicoat coatings. YORK recommends that for corrosive environments that copper fins be used to protect the evaporator and/or condenser coils. In areas where chemicals
that can corrode copper are present, such as ammonia, YORK recommends that the black fin or Technicoat
coating be used for maximum protection.
Copper Fin Condenser Coil
Copper fins can be used instead of aluminum for additional 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 precoated application epoxy on aluminum fin stock to guard
from corrosive agents and insulate against galvanic potential. It is used for mild seashore or industrial locations. This can provide corrosion resistance comparable
to copper fin coils in typical seashore locations.
Post-Coated Condenser Fins
T echnicoat (a post-coated application of epoxy) can be
used for seashore and other corrosive applications with
the exception of strong alkaloides, oxidizers, wet bromide, 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
be further reviewed and approved by the consulting engineer 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
proper building exhaust, the building may become overpressurized. 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
what is entering the building. This provides a slight positive pressure in the building.
100% modulating exhaust with building static
pressure sensing and control
The 100% exhaust system can be configured with either control actuated dampers or VFDs for modulating
control. The unit controller monitors the building pressure using a differential pressure transducer and maintains the required building static pressure by modulating the exhaust control. If the building has 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
The 100% exhaust system can be configured for on/off
operation eliminating the expense of the damper actuators or VFDs. This exhaust system can be controlled
by either the outside air damper position, or a building
static pressure sensor.
Barometric exhaust
Barometric exhaust can be used when smaller amounts
of air at low static pressure variations within the building or other means of building exhaust are employed.
Barometric exhaust is commonly used where there are
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 eco
2
footprint. 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
the curb footprint for through-the-curb utility connections.
YORK INTERNATIONAL
9
Application Data (continued)
The curb should be located according to the location
recommendations above, and properly sealed to prevent moisture and air leakage into and out of the duct
system. Flexible collars should be used when connecting the duct work to prevent unit noise transmission
and vibration into the building.
Duct work should be supported independently of the
unit.
ACOUSTICAL CONSIDERA TIONS
The eco
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.
Even with these equipment design features, the acoustical characteristics of the entire installation must never
be overlooked. Additional steps for the acoustical characteristics of a rooftop installation should be addressed
during the design phase of a project to avoid costly alterations after the installation of the equipment. During
the design phase of a project, the designing engineer
should consider, at a minimum, the imp act of the equipment location, rooftop installation, building structure, and
duct work.

6. Required total and sensible capacities are 991 mbh
and 681 mbh, respectively . The total capacity is 82.6
tons, therefore a model YP AL085 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 temperature to match the 24,000 cfm and 67°F entering
wet bulb temperature condition. The resulting conditions 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
mbh = 946 mbh
* Note, net heating capacity is approximate because this example
uses the bhp calculated based on a wet evaporator coil (for
cooling mode).
