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
complete 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 damag-
ing material while a polymer mesh further protects the coil against
smaller particles.
• Isolated Compressor Compartment – A molded composite
bulkhead isolates the compressor from the rest of the unit reduc-
ing 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 pres-
sure relief valve and temperature sensors which protect the com-
pressor if undesirable conditions occur.
• Environmentally Friendly Refrigerant – Next generation refrig-
erant R-410A delivers environmentally friendly performance, with
zero ozone depletion.
• Durable Finish – Automotive quality finish provides the ultimate
protection 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 provide 33% greater durability than conventional pow-
der-coat finishes.
• Lower Installed Cost – Designed to provide enhanced installabil-
ity 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 technol-
ogy adapted from aeronautic and defense engineering provides
for whisper quiet operation by allowing airflow to flow smoothly
and efficiently 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,
isolated compressor compartment and two-stage compressor are
engineered as a system to reduce overall sound to a mere whis-
per.
• Complete System Control – All models utilize the exclusive
microprocessor based, on-demand, defrost control system. This
system provides optimal comfort, efficiency, and constant montor-
ing of the entire system for reliable operation. defrost cycles occur
only when necessary. an adjustable balance point insures supple-
mental 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 tempera-
ture and/or high pressure), the unit will automatically shut down to
protect the refrigeration system, and switch to back-up heat. On-
board diagnostic 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.
Certified in accordance with the Unitary Small Equipment certification
program, which is based on ARI Standard 210/240.
