York Champion Series Quick start guide

DESCRIPTION
These packaged heat pumps are designed for outdoor instal-
lation. 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
efficienciesof10SEERorgreater, 3.0 COPorgreaterandupto
7.0 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 on that curb after the internal load has
been determined. Field convertible duct connections from
side shot to down shot allows the installer to have greater
flexibility and needs 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 well
under 500 pounds.
All units are completely wired, charged with R-22 and tested
prior to shipment. Unique test stations using a new state of the
art computerized process system are used to insure product
quality. Refrigerant charge, and component part numbers are
verified via computers at manufacturing point. Vital run test sta-
tistics such as system pressure, motor currents, air velocity and
temperature and unit vibration are monitored and recorded by
the system to insure unit performance.
Equal size, side supply and return duct connections allows
easyhook-upofductstomatchlowcrawlspaceswithouttran-
sition pieces.
UTILITY CONNECTIONS MADE EASY - Electrical utility
knockoutsareprovidedthroughthebottomaswellastheside
ofthe unit. Utility connectionscan be made quicklyand with a
minimum amount of field labor. A field supplied and field in-
stalled electrical disconnect switch must be installed.
CONVERTIBLE AIRFLOW DESIGN - The bottom duct open-
ings are covered when they leave the factory ready to be used
forasidesupply/sidereturnapplication.Ifabottomsupply/bot-
tom 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
andnoaccessorypanelisnecessary.Convertibleairflowdesign
allows maximum field flexibility and minimum inventory.
CONDENSATEPAN-A non-corrosive,long-lasting,water-tight
panispositionedbelowtheevaporatorcoiltocollectanddrainall

up.Thecondensate panconformstoASHRAE62-89standards

SEER = Seasonal Energy Efficiency Ratio - the total cooling output in BTU's during a normal annual usage period for cooling divided by the total electric power input in watt-hours during the
same period.
COP = Coefficient of Performance - the total heating capacity provided by the refrigeration system, including circulating fan heat but excluding supplementary resistance (BTU's per hour)
divided by the total electric input (watts) x 3.412.
HSPF = Heating Seasonal Performance Factor - the total heating output during a normal annual usage period for heating divided by the total electric power input during the same period.
(Based on Region IV minimum design heating requirement).

NOTE: 1. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.
2. The pressure thru the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver
less CFM during full economizer operation.
