DESCRIPTION
The YMA Series unit is the outdoor part of a versatile hea t 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. Addon 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.
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, Af fi nity unit s are now a vailab le wi th a ch oice 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 ultimate protection from harmful U.V. rays and 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 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 filterdrier 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 optimal comfort and to monitor the overall system for reliable
operation. The defrost control system continuously monitors
the space environment to maintain optimum efficiency. It initiates 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 system 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 certification program, which is based on ARI Standard 210/240.

1 Only the TXV kits listed above are approved for use in these systems. The charge adder is the same as that listed for the orifice.
2 Models with recipr oca ting compressors requir e start kits when matched to TXV indoor coils.
3 Systems matched with furnaces or air handlers not equipped with blower-off delays may require blower Time Delay Kit
2FD06700224.
4 These orifices or TXVs are factory mounted in the flow device of each indoor coil (701, 702, 703 indicates 1TV07…series). A “T”
suffix indicates a coil or air handler with a factory mounted TXV.
PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaporator and 15 feet of interconnecting line tubing.
2. Verify the TXV and additional charge required for specific evaporator coil in the system using the above table.
3. Additional charge for the amount of interconnecting line tubing greater than 15 feet at the rate specified on the previous page.
4. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for
evaporator + adder for line set.
