DESCRIPTION
The YMA 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.
• Color Grilles - Engineered around the needs and wants of
the consumer, Affinity units are now available with a choice of
color options designed to compliment any home.
• Protected Compressors – Each compressor is protected
against abnormal pressures by an internal pressure relief
valve and factory installed high pressure controls. Additional
protection against moisture and debris is provided by factory
installed liquid line filter driers.
• Durable Finish – Automotive quality finish provides the ulti-
mate protection from harmful U.V. rays and rust creep ensur-
ing long-lasting, high quality appearance. A powder-paint
topcoat is applied over a baked-on primer, using a galva-
nized, 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
and angled service valves to reduce overall installation time
and cost.
• Low Operating Sound Levels – Unit discharges upward to
reduce sound transmission. An integrated fan venturi
reduces fan sound levels even further. An isolator-mounted
compressor covered by a sound-deadening blanket which is
mounted to a composite polymer base pan insures unwanted
compressor noises are not introduced into the environment.
• 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 and to 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 reduce heating
costs and improve reliability. In the event improper operating
conditions occur, the control 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.
• Composite Base - Strong and durable composite base pan
resists rust and corrosion while it helps reduce vibrations and
noise.
• Low RPM fan motor - Helps to reduce airflow noise.
Certified in accordance with the Unitary Small Equipment certifi-
cation program, which is based on ARI Standard 210/240.
