SINGLE PACKAGE AIR CONDITIONERS
HORIZONTAL INDOOR &
CONDENSER AIR FLOW
036-21187-001 REV A (0301)
DESCRIPTION
York horizontal ductable air conditioning packages offer a complete line of unit options for indoor, through-the-wall installations
for high and low rise building applications.
York’s compact, low profile indoor design protects from potential
vandalism, weathering and eliminates the need for any unsightly
exterior equipment.
Floor-by-floor installation provides independent zone and temperature control. Renovation and restoration projects are simplified
where roof load, cooling tower, and construction restrictions can
present installation problems.
The air cooled DHH horizontal series units are available from 2 to
15 tons.
York’s DHH horizontal air cooled indoor air conditioning features
high efficiency, quality engineering and dependable operation.

charge. The 12 and 15 ton models are shipped as separate
evaporator and condensing unit modules (nitrogen holding
charge only). The 4 through 10 ton units include refrigeration
line shut-off valves to allow the units to be field split. All packages/models are designed for suspended mounting via integral structural channels .
CABINET
Gauge corrosion resistant "Galvalume" coated steel. The
entire unit interior (both evaporator and condensing section)
is insulated with 1/2" thick 2 LB density insulation. Service
panels are equipped with 1/2" thick 2 lb. density insulation.
Service panels are equipped with lifting handles for ease of
removal and handling.
COMPRESSORS
compressors. Compressors are mounted on rubber isola tors
to minimize v ibration trans mission. Inte rnal overload pr otection is provided. Extern al h igh pr es su re an d lo w pr es su re c utout switches are included in each compressor control circuit.
Crankcase heaters are standard on all models.
REFRIGERANT CIRCUIT
refrigeration circu it. The 8 to 15 to n units featu re two ind ependent refrigeration circuits. Each circuit includes an adjustable
thermal expansion valve (with external equalizer), liquid line
filter drie r, sight glass/ moisture indicato r, and service ga uge
ports.
EVAPORATOR AND CONDENSER COILS
and condenser coils are constructed of internally enhanced

- The 2 to 5 tons units use a singl e
- The evaporator
copper tubes mechanically bonded to rippled aluminum plate
fins. Both coils are em plo ye d in a dra w -thro ugh co nfig uration.
Large evaporator coil face area minimizes potential water
blow-off (max face velocity is 550 fpm at rated airflow).
INDOOR/OUTDOOR FANS
- Forward curved, double inlet
and double width centrifugal blowers are used for both evaporator and condenser air movement. blow wheels are fabricated of galvanized steel. Blowers employ solid steel shafts,
supported in permanently lubricated ball bearing. All blowers are belt driven in permanently lubricated ball bearing. All
blowers are belt driven. Variable-pitch motor sheaves allow
for field adjustment of blower rpm.
ELECTRICAL/CONTROLS
- All units are comp letely fact ory
wired with all necessary controls. Manual reset protection is
provided on both evaporator and condenser motors. A manual reset circuit is also provided on each compressor control
circuit in the event of high/low pressure cutout. A 24 volt control circuit with oversize transformer, is provided for field connection.
FILTERS
- All models are shipped with 2 inch thick mediumefficiency throwaway filters factory installed. Filter rack is
internal to the cabinet.
