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.

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

Equal size, side supply and return duct connections allow

easy hook-up of ducts to match low crawl spaces without

transition pieces.

OPERATING EFFICIENCY

All units provide high operating efficiencies of 13 SEER, 3.3

COP or greater, and 7.7 HSPF. All efficiencies exceed leg-

islated minimum levels.

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.

ON SITE FLEXIBILITY

All model sizes share a common, compact design cabinet

with a single footprint. The installer has the flexibility of set-

ting one curb or pad and placing the proper tonnage unit

after the internal load has been determined. Field convert-

ible duct connections, from side shot to down shot, allows

the installer greater flexibility and the need to carry less

inventory.

CONVERTIBLE AIRFLOW DESIGN

The bottom duct openings are covered when they leave the

factory. They are ready for a side supply / side return appli-

cation. 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 acces-

sory panel is necessary. Convertible airflow design allows

maximum field flexibility and minimum 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.

FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

PROTECTED COMPRESSOR

rate field accessories of single enthalpy and dual

enthalpy are also available.

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 compres-

sor, if undesirable operating conditions occur.

SINGLE ENTHALPY SENSOR

Sensor replaces dry bulb sensor standard in econo-

mizer kit. Provides improved economizer operation by

sensing the dry bulb temperature from outdoors, plus

the enthalpy content of the outdoor air.

EXCLUSIVE COIL DESIGN

Grooved copper tubes and enhanced aluminum fin

construction improves heat transfer for maximum effi-

ciency and durability.

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.

LOW MAINTENANCE

Long life, permanently lubricated condenser and evap-

orator fan motor bearings, need no annual mainte-

nance. Blower assembly can be easily cleaned by the

unique “Slip Track” slide-out blower assembly.

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 adapt-

ers. 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.

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

A large, single hinged panel covers the electrical con-

trols and makes servicing easy. The blower compart-

ment 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 mainte-

nance and ease of trouble shooting.

HAIL GUARD KIT

Kit contains protected grilles made of expanded alumi-

num grilles with full perimeter 1-1/2 inch frame. Sloped

hoods are also included to assure maximum protec-

tion.

REPLACEMENT PARTS

FILTER / FRAME KIT (SINGLE PHASE ONLY)

The installer has no need to carry an inventory of

unique parts or needs special training to replace any of

the components parts for these units. All are easily

obtained from Source 1 or other major part houses.

Kit contains the necessary hardware to field install

return air filters into the base unit. Pre-cut filter racks

and appropriate cleanable standard size filters are

shipped in one kit (1" filter is supplied). This kit is avail-

able for single phase horizontal or vertical duct applica-

tion only. Standard in all 3 Phase models.
