DESCRIPTION
The YZE Series unit is the outdoor part of a versatile heat pump
system. It is designed to be custom matched with one of our com-
plete line of evaporator sections, each designed to serve a specific
function. Matching air handlers are available for upflow, downflow,
and horizontal left or right application to provide a complete system.
Electric heaters are available if required. Add-on coils are available
for use with upflow, downflow, or horizontal furnaces. Field installed
accessories are available as needed.
WARRANTY
5-year limited parts warranty.
10-year limited compressor warranty.
Premium System Warranty - Limited lifetime compressor and 10-
year parts when matched with an approved York Affinity furnace or
UPG air handler and coil.
FEATURES
• Superior Coil Protection – A stamped decorative metalcoil guard
completely protects coil from debris and other large damaging mate-
rial while a polymer mesh further protects the coil against smaller
particles.
• Isolated Compressor Compartment – A molded composite bulk-
head isolates the compressor from the rest of the unit reducing
sound and vibration.
• Protected Compressors – Each compressor is protected against
high and low pressure as well as excessive temperature. This is
accomplished by by the simultaneous operation of a high pressure
relief valve and temperature sensors which protect the compressor if
undesirable conditions occur.
• Environmentally Friendly Refrigerant – Next generation refriger-
ant R-410A delivers environmentally friendly performance, with zero
ozone depletion.
• Durable Finish – Automotive quality finish provides the ultimate pro-
tection from harmful U.V. rays as well as rust creep ensuring long-
lasting high quality appearance. A powder-paint topcoat is applied
over a baked-on primer, using a galvanized, zinc coated steel base
material. The result is a finish that has been proven in testing to pro-
vide 33% greater durability than conventional powder-coat finishes.
• Lower Installed Cost – Designed to provide enhanced installability
by featuring a slide-down control compartment allowing easy access
to control components along with angled service valves to reduce
overall installation time and cost.
• Low Operating Sound Levels – A fan design boasting technology
adapted from aeronautic and defense engineering provides for whis-
per quiet operation by allowing airflow to flow smoothly and effi-
ciently across the fan tips.
• Filter-Drier – A factory installed, solid core liquid line filter-drier fil-
ters harmful debris and moisture from the system.
• Easy Service Access – A full end, full service, access panel with
handle makes for easy entry to internal components.
• Long Lasting Operation – Strong and durable composite base pan
provides added strength while resisting rust and corrosion as well as
reducing sound and vibration.
• Quiet drive system - The swept-wing fan, composite base pan, iso-
lated compressor compartment and two-stage compressor are engi-
neered as a system to reduce overall sound to a mere whisper.
• Complete System Control – All models utilize the exclusive micro-
processor based, on-demand, defrost control system. This system
provides optimal comfort, efficiency, and constant montoring of the
entire system for reliable operation. defrost cycles occur only when
necessary. an adjustable balance point insures supplemental heat is
brought on only when required to meet the space load, for optimum
efficiency and reliability.
In the event improper operating conditions occur (high temperature
and/or high pressure), the unit will automatically shut down to protect
the refrigeration system, and switch to back-up heat. On-board diag-
nostic LED’s guide the technician to the source of the problem, and
an output signal from the control to the thermostat will alert the
homeowner. The control also features non-volatile memory, which
preserves trouble codes in the event of power loss. An anti-short
cycle timer extends the life of the compressor by preventing short-
cycling.
• Agency Listed - U.L. and C.U.L. listed - approved for outdoor appli-
cation. The unit is certified in accordance with the Unitary Small
Equipment cerification program, which is based on ARI Standard
210/240.
