CONDENSING SECTION
Scroll Compressors
Reliable, efficient, trouble-free operation is the true
measure of a packaged rooftop’s value. That’s why
YORK YPAL Packaged Rooftop Air Conditioners
use established scroll-compressor technology to de-
liver dependable, economical performance in a wide
range of applications. With the YORK YPAL 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.
Multiple Compressor Staging
Through the use of the scroll compressor, the YORK
YPAL has the ability to stage it’s cooling by enabling
and disabling multiple single stage compressors on
multiple circuits. These compressors are manifolded
together in two independent circuits.
Compressor Circuiting
The YORK YPAL is designed so that only 2 scroll
compressors are in tandem within one refrigeration
circuit. This means more reliable compressors, and
less equipment down time. With multiple circuits, if
a compressor should ever fail on one circuit, the other
circuit/s will remain operational to work to maintain
occupied loads. The YORK YPAL system has 2 cir-
cuits in the unit.
ECOLOGICAL AND ECONOMICAL DESIGN
High Efficiency YORK YPAL rooftop units are opti-
mized for HFC-410A refrigerant. YORK provides the
FIRST standard product offering that meets the latest
ASHRAE 90.1 energy efficiency requirements.
Cooling and Heating
Superior operating performance provides lower oper-
ating 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 economizers provide 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 ventila-
tion and comfort are controlled through the micropro-
cessor control panel.
Premium-Efficiency Motors
Premium-efficiency motors are available for optimum
energy efficiency. All motors used on the YORK YPAL
packaged rooftop air conditioner meet U.S. EPACT
1992 minimum requirements.
High-efficiency motors are standard. Motors are avail-
able in ODP or TEFC construction.

Compressor Sound Blankets
Optional factory installed sound blankets can be in-
stalled to further reduce compressor sound attenuation.
Replaceable Core Filter Driers
The optional replaceable core filter drier on the YORK
YPAL provides a convenient means for maintaining
and optimizing the units refrigeration system. Elimi-
nating additional field penetrations into the refrigerant
circuit, which could lead to potential problems, reduce
the worry of refrigerant circuit contamination.
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 colder months. Low ambient con-
trols are available on all systems offering higher roof-
top cooling capacity than competitive units.
Condenser Fan Motors
The condenser fan motors used on the YORK YPAL
unit are Totally Enclosed Air Over (TEAO) to provide
maximum durability through any season.
Condenser Coils
Are available in various materials and coatings to suit
almost any type of application. Aluminum or copper
fins, pre-coated or post-coated fins are available. The
coating is applied using an epoxy coating on the alumi-
num coil. Each coil option is beneficial when the unit
must operate under extreme conditions. The use of an
epoxy coated coil is recommended for units installed in
a corrosive environment.
Hot Gas By-pass
Is standard on VAV units.
Condenser Coil Protection
The YORK YPAL is available with a wire mesh guard
for optimum coil protection.
HEATING SECTION
Staged Gas Heat
The YORK YPAL rooftop gas furnace is an induced-
draft gas furnace designed for high efficiency and reli-
ability. 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.
Up to three stages of heat are available.
An optional stainless steel heat exchanger is also avail-
able.
Electric
The YORK YPAL is also available with an electrical
heater that can range from 40kW up to 50kW. Depend-
ing on the size of the heat required, the YORK YPAL
can have 3 steps of control helping to provide tighter
control of the supply and zone conditioned air. With
the utilization of this multi step function, the YORK
YPAL can effectively reduce energy consumption by
bringing on smaller stages of heat while maintaining
the maximum level of comfort.
Steam and Hot Water
This option will be available in the future.
AIR MANAGEMENT
The raised access floor concept is a proven design ideal
for office buildings that house today’s modern busi-
ness that relies on critical information technologies
to maintain high productivity levels. The unmatched
flexibility offered by raised floor systems allows for
significant costs savings and reduced downtimes when
a fast-paced economy demands office space reconfigu-
ration.
DWDI Airfoil Fans
High efficiency fans are used to improve application
flexibility, and address sound and application concerns.
Building Pressure Control
Exhaust fans and barometric relief dampers are avail-
able to meet building pressure control requirements.
Select the most appropriate option for a given applica-
tion.
Low Sound Options
Allow for application of the YORK YPAL unit in
sound-sensitive applications such as theaters and
downtown areas. Contact Johnson Controls for more
details on site-specific requirements.

Variable Frequency Drives
When a VAV unit is ordered, the YORK YPAL comes
standard with variable frequency drives (VFD’s). The
VFD can optimize a systems performance by modulat-
ing the supply fan motor speed to reduce energy con-
sumption by as much as 40% while maximizing oc-
cupant comfort.
Fan Spring Isolation
Two-inch spring isolation is used to prevent vibration
transmission from the rooftop unit’s supply fan to the
building.
CONTROLS
Rooftop Controller
The unit is designed to use the Simplicity Elite control.
This control has been used with the 25 to 40 ton Millen-
nium product for many years. The control is designed
to operate with conventional room control input. This
allows the same control to be used on installations re-
quiring 25 to 60 tons of cooling.
The board is equipped with four program buttons and
two character displays for use by the technician. They
allow for access to the most important board functions,
current operating data, and current alarms as well as
the last five alarms in the history memory buffer. The
buttons and displays are also used to program the con-
trol with the correct configuration and setpoints.
The control can also be connected to a computer for
greater access to programming and operating informa-
tion.
Communication
The controller is designed to communicate using Mod-
bus RTU protocol. Through the addition of a Mod-
LINC translator, the unit can also communicate using
BACnet MS/TP protocol.
INDOOR AIR QUALITY
Double Sloped Stainless Steel Drain Pan
The YORK YPAL’s standard Stainless Steel drain pan
meets ASHRAE 62 requirements for condensate drain-
age to improve indoor air quality. Solid wall liners
encase insulation and prevent moisture damage. Ad-
ditional benefits include easy cleanability and isolates
insulation from conditioned airstream.
Double Wall Construction
Is the standard construction of the YORK YPAL and
incorporates powder coated pre-fabricated outer panels
and corner post for maximum exterior surface protec-
tion.
Factory Shrinkwrap
All YORK YPAL rooftop units can be ordered from
the factory with an optional factory-fresh shrinkwrap
packaging. This eliminates the contractors worries
about dirt and debris clogging up condenser coils or
moisture leaking into the air handler on the units way
to the job site or rigging yard.
Demand Ventilation Option
Can be incorporated into the unit to improve indoor air
quality and help manage indoor pollutants such as CO2
or other harmful airborne contaminates out of the occu-
pied spaces for maximum comfort and safety. Activa-
tion of this sequence can easily be accomplished using
a CO2sensor installed in the conditioned space. CO2
sensors are typically used with demand ventilation;
however other sensors may be applied to control in-
door contaminants such as volatile organic compounds
(VOCs).
Smoke Purge
Is also available to evacuate smoke due to fire from a
room or zone.
Filtration
The YORK YPAL is configured for various types
of filtration to meet the different needs and require-
ments of today's rooftop applications, including 2-inch
throwaway, pleated, carbon, and cleanable filters and
12-inch high efficiency rigid filters.
ELECTRICAL
Single Point Power
The YORK YPAL unit comes standard with single
point power connections to make installation quick
and easy.
Dual Point Power
Can be factory installed for applications that require
the mechanical heating and cooling functions to be
separated from the air handling functions. This enables
the unit to be operated in an emergency condition while
minimizing power consumption.

LOCATIONS AND CLEARANCES
General
The YORK YPAL air conditioning units are designed
for outdoor installation. When selecting a site for in-
stallation, be guided by the following conditions:
1. Unit must be installed on a level surface.
2. 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.
3. Also avoid locations beneath windows or between
structures.
4. Optional condenser coil protection should be used
for seashore locations or other harsh environments.

SECTION 2 – INSTALLATION
5. The unit should be installed on a roof that is structur-
ally strong enough to support the weight of the unit
with a minimum of deection. 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 transmis-
sion of sound and vibration. Ideally, the center of
gravity should be located over a structural sup-
port or building column.
6. Location of unit(s) should also be away from
building ue stacks or exhaust ventilators to pre-
vent possible reintroduction of contaminated air
through the outside air intakes.
7. Be sure the supporting structures will not obstruct
the duct, gas or wiring connections.
Location
Of the many factors that can affect the location of
equipment, some of the most important to consider are
Structural, Acoustical and Service clearances. Proper
attention should be made at the design stage to ensure
proper structural support. In cases where equipment is
being replaced, be aware of building design to insure
support is adequate for the application.
The next most important consideration in applying
roof top equipment is that of sound from the equip-
ment. Special care should be made to keep the roof
top unit away from sound sensitive areas such as con-
ference rooms, auditoriums and executive offices and
any other room that may have potential for tenant oc-
cupancy. Possible locations could be above hallways,
mechanical or utility rooms.
Finally, service clearances should be maintained in
rooftop design to insure safe access to the unit. Unit
clearances are designed so that technicians have
enough space between units, building walls, and edges
of building to gain access safely. In cases where space
is limited, please call your local Johnson Controls rep-
resentative for additional information.
The clearances shown are to provide
adequate condenser airow and service
access to inside the unit. Additional clear-
ance should be considered for component
replacement such as compressors, evapo-
rator coils, and supply or exhaust fans.
While it is a common practice to operate
the fan as soon as possible (air movement
during construction) on the job site, the
incomplete ductwork and missing diffuser
grilles will greatly reduce air resistance
and will allow the fan to operate beyond
design parameters. This practice may
result in water carry over and ooding of
the unit. Also, the supply fan motor may
overamp and become damaged.

RIGGING AND HANDLING
Proper rigging and handling of the equipment is man-
datory during unloading and setting it into position to
retain warranty status. All lifting lugs must be used to
prevent twisting and damage to the unit.
Care must be taken to keep the unit in the upright posi-
tion during rigging and to prevent damage to the water-
tight seams in the unit casing. Avoid unnecessary jar-
ring or rough handling.
Typical rigging using proper spreader bars and cables
is shown in Figure 4 on page 19. See Figure 3 on
page 19 for number and location of the lifting lugs
by unit size. It is also mandatory that an experienced
and reliable rigger be selected to handle unloading and
final placement of the equipment. The rigger must be
advised that the unit contains internal components and
that it be handled in an upright position. Care must be
exercised to avoid twisting the equipment structure.
Unit weights are listed under Figure 3 on page 20 in
this manual. These weights must be referred to when
selecting a crane for rigging and figuring roof weight
loads. Contact your Johnson Controls Sales Office if
you have any questions regarding unit weights.
