DESCRIPTION
The YZB 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 horizon-
tal furnaces. Field installed accessories are available as
needed.
WARRANTY
5-year limited parts warranty.
10-year limited compressor warranty.
FEATURES
• Superior Coil Protection – A stamped decorative metal coil
guard completely protects coil from debris and other large
damaging 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
reducing sound and vibration.
• Protected Compressors – Each compressor is protected
against high and low pressure as well as excessive tempera-
ture. 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
refrigerant R-410A delivers environmentally friendly perfor-
mance, with zero ozone depletion.
• Durable Finish – Automotive quality finish provides the ulti-
mate 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 gal-
vanized, zinc coated steel base material. The result is a finish
that has been proven in testing to provide 33% greater dura-
bility 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 tech-
nology 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 filters 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.
• Complete System Control – These heat pumps utilize the
unique microprocessor defrost control system to provide opti-
mal comfort as well as monitor the overall system for reliable
operation. The defrost control system continuously monitors
the space environment to maintain optimum efficiency. It ini-
tiates defrost only when necessary to further reduced heating
costs and improve reliability. Supplemental heat can only
operate below the balance point and then only upon need. In
the event improper operating conditions occur (high tempera-
ture and/or high pressure), the will automatically shut the sys-
tem down to extend the life of the heat pump. Rapid cycling is
prevented by use of an internal anti-recycle timer. The defrost
control features an internal memory to aid the technician in
troubleshooting, reducing service time and cost.
Certified in accordance with the Unitary Small Equipment certifi-
cation program, which is based on ARI Standard 210/240.
