2 THRU 5 NOMINAL TONS
13 SEER
FACTORY MOUNTED TXV
DESCRIPTION
York® Affinity™ Series packaged heat pumps are designed
for outdoor installation. Only utility and duct connections
are required at the point of installation.
Field-installed electric heater accessories are available to
provide electric heat, if required.

STANDARD FEATURES / BENEFITS
OPERATING EFFICIENCY
All units provide high operating efficiencies of 13 SEER, 3.3
COP or greater, and 7.7 HSPF. All efficiencies exceed legislated minimum levels.
ON SITE FLEXIBILITY
All model sizes share a common, compact design cabinet
with a single footprint. The installer has the flexibility of setting one curb or pad and placing the proper tonnage unit
after the internal load has been determined. Field convertible duct connections, from side shot to down shot, allows
the installer greater flexibility and the need to carry less
inventory.
LOWER INSTALLATION COST
Installation time and costs are reduced by easy power and
control wiring connections. The small base dimension
means less space is required on the ground or roof. Plus,
the installer can fit this unit between the wheel wells of full
size pick-up truck. All models are under 500 pounds.

All units are completely wired, charged with R-22 and
tested prior to shipment. Unique test stations, are used to
insure product quality. Refrigerant charge, and component
part numbers are verified via computers at manufacturing
point. Vital run test statistics, such as, system pressure,
motor currents, air velocity and temperature unit vibration
are monitored and recorded by the system to insure unit
performance.
Equal size, side supply and return duct connections allow
easy hook-up of ducts to match low crawl spaces without
transition pieces.
UTILITY CONNECTIONS MADE EASY
Electrical utility knockouts are provided through the bottom,
as well as the side of the unit. Utility connections can be
made quickly and with a minimum amount of field labor. A
field supplied and field installed electrical disconnect
switch must be installed.
CONVERTIBLE AIRFLOW DESIGN
The bottom duct openings are covered when they leave the
factory. They are ready for a side supply / side return application. If a bottom supply / bottom return application is
desired, you simply remove the two panels from the bottom
of the unit and place them in the side supply / side return
duct openings. No panel cutting is required and no accessory panel is necessary. Convertible airflow design allows
maximum field flexibility and minimum inventory.

CONDENSATE PAN

TOP DISCHARGE

A non-corrosive, long-lasting, water-tight pan is positioned below the evaporator coil to collect and drain all
condensate; less collection of stagnate condensate will
build-up. The condensate pan conforms to ASHRAE
62-89 standards (Ventilation for Acceptable Indoor Air
Quality).

The top discharge condenser fan does not disrupt
neighboring areas and does not dry-out vegetation surrounding the unit. The warm air from the top mounted
fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit
applications.

CONDENSATE DRAIN

OUTDOOR COIL GRILLE

The heavy duty, inch NPTI copper connection is more
tolerable during installation and is more durable over
time. The connection is rigidly mounted to assure
proper fit and leak tight seal.

A multi-piece totally enclosed, rigidly mounted outdoor
coil grille provides protection from objects and personnel after installation. It also provides protection during
transit and installation.

DURABLE FINISH

LOW OPERATING SOUND LEVEL

With a heavy duty cabinet made of powder-painted,
galvanized steel, the neutral color blends into surrounding areas. The powered paint provides a better
paint to steel bond, which resists corrosion and rust
creep. The special primer formulas and glossy earth
tone finish insure less fading when exposed to sunlight
and offers a more attractive on site appearance. This
paint finish exceeds ASTM-B117 standards for 1000
hours salt spray rating, the highest in the industry.

The upward air flow carries the normal operating noise
up and away from the living area. The rigid top panel
effectively isolates any motor sound. Isolator mounted
compressor and the rippled fins of the condenser coil,
muffle the normal fan motor and compressor operating
sounds. The unique formed base pan also aids in
sound alterations with it's “Super-Structure” design.
This design strategically places embossments in the
pan for optimum strength and rigidity.

FULL PERIMETER BASE RAILS

FAN SYSTEM

The easily removable base rails provide a solid foundation for the entire unit and protects the unit during shipment. The rails provide fork lift access from all sides.
Rigging holes are, provided also so that an overhead
crane can be used to place the unit on a roof. On applications when the unit is placed on a pad, the base will
keep the unit off the pad to deter corrosion. On applications where height is limited, the 2-3/8 inch high base
rails may be removed on location.

All models operate over a wide range of design conditions with an (E.C.M.) electronically commutated motor
that automatically adjusts the blower speed to meet a
wide range of static requirements. These units easily
match all types of applications and provides greater on
site flexibility to match comfort requirements.

MORE ATTRACTIVE APPEARANCE
A single piece “Water Shed” top cover containing a top
discharge condenser fan arrangement requires less
square footage on installation and provides a wider
variety of installations. The one piece design adds
greater water integrity. Rounded corners with water
drip edges add to the attractive appearance. The cabinet panels have a non-fibrous insulation that reduces
insulation fibers into conditioned area.

SIMPLE CONTROL CIRCUIT
A low voltage printed circuit board contains a low voltage terminal strip. The electrical control box is not
located in the compressor compartment. All wiring
internal to the unit is color/number coded.
CONTROLS
Reliable demand defrost control provides defrost.
Defrost control also provides an “X” terminal to provide
a 24 volt signal for room thermostat “LED” indication of
unit lockout, plus, built in 5 minute anti-short cycle protection.

PROTECTED COMPRESSOR
The compressor is internally protected against high
pressure and temperature. This is accomplished by the
simultaneous operation of high pressure relief valve
and a temperature sensor which protects the compressor, if undesirable operating conditions occur.
EXCLUSIVE COIL DESIGN
Grooved copper tubes and enhanced aluminum fin
construction improves heat transfer for maximum efficiency and durability.
LOW MAINTENANCE
Long life, permanently lubricated condenser and evaporator fan motor bearings, need no annual maintenance. Blower assembly can be easily cleaned by the
unique “Slip Track” slide-out blower assembly.
SECURED SERVICE ACCESS PORTS
Protected, externally mounted, re-usable service
access ports are provided on both the high and low
lines for ease of evacuating and charging the system.
EASY SERVICE ACCESS

rate field accessories of single enthalpy and dual
enthalpy are also available.
SINGLE ENTHALPY SENSOR
Sensor replaces dry bulb sensor standard in economizer kit. Provides improved economizer operation by
sensing the dry bulb temperature from outdoors, plus
the enthalpy content of the outdoor air.
DUAL ENTHALPY SENSOR
Additional sensor to single enthalpy sensor. Sensor
selects both the return air temperature dry bulb and
humidity, in conjunction with the single enthalpy, to
determine the most economical mix. Single Enthalpy
sensor also required.
UPGRADE PRESSURE PACKAGE
Contains screw in type High pressure, Low Pressure/
Loss of Charge switch, freeze protection switch and
lockout relay. Switches are placed onto existing
Schrader ports located in the unit by furnished adapters. When abnormal conditions are sensed through the
pressure switches, the unit will lock out, preventing any
further operation until reset or problem is corrected.
Package agency approved.

A large, single hinged panel covers the electrical controls and makes servicing easy. The blower compartment has an additional large panel with a built-in
handle tab. Removing this panel will allow the blower
assembly to slide-out for easy removal for maintenance and ease of trouble shooting.
