YORK INTERNATIONAL
Reliable Cooling and Heating Technology
• Reliable, efficient, trouble-free operation is the true
measure of a packaged rooftop’s value. That’s why
YORK eco
2
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 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-
est sealing technology to avoid metal-to-metal con-
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 eco
2
rooftop 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
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 pro-
vide redundancy not available in single power
burner applications.
Serviceability
• OptiLogic
TM
– Fully-integrated factory-packaged
controls are standard on every unit and include a
display unit with a 4x20 character LCD display.
OptiLogic
TM
continually monitors all control setpoints
and configurations. If a unit sensor fails, the con-
troller 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 recla-
mation and charging of system refrigerant are avail-
able to minimize downtime and simplify the service
and repair task.
• Convenience Outlet – For maintenance tasks re-
quiring power tools, an optional 110V GFCI power
supply can power lights, drills or any other power
hand tool needed.
• Filter Maintenance Alarm – An optional filter main-
tenance alarm indicates when a filter becomes dirty
and requires replacement or cleaning.
Install with Ease and Safety
• Factory Run-Tested – Each unit is subjected to a
series of quality assurance checks as well as an
automated quality control process before being run-
tested. Fans and drives are balanced at the factory
during testing. The factory run-test ensures safe,
proper operation when the unit is installed and re-
duces installation and commissioning time.
• Single-Point Power Connection – Single-point
power connection reduces installation time by pro-
viding 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. eco

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 con-
trol points within the unit are factory-installed, wired
and tested.
• Non-Fused Disconnect – An optional factory-in-
stalled non-fused disconnect switch simplifies unit
installation and serviceability by eliminating the need
for a separate disconnect switch. Check local codes
for acceptability.
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 competi-
tive 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 trans-
mission characteristics.
• Compressor Sound Blankets – For applications
in sound-sensitive areas, compressor sound blan-
kets are available to reduce sound emitted from
the rooftop unit.
