INTRODUCTION
Performance and dependability in a no-nonsense heat pump.
The R-Series units by YORK are completely self-contained heat pumps. This equipment employs a water-torefrigerant heat exchanger to extract (heating cycle) or reject (cooling cycle) heat from/to a circulating
water-loop.
The high-quality feature set delivers robust construction and reliable performance that exceeds ASHRAE 90.1
requirements. Available with an insulated refrigerant-circuit, the R-Series is equally suited for water-loop and lowtemperature, geothermal applications.
For commercial installations ranging from schools to multi-story office space, R-Series Water Source Heat Pumps
by YORK provide the performance and dependability necessary to suit today’s demanding installation
requirements.

Technical Guide: YK145.00-EG4 (309) Water Source Heat Pumps
SPECIFICATIONS
GENERAL
All R-series models ½ - 6 ton ship as factory-charged
packages, complete with R-410A refrigerant. Horizontal
(RSH) units are designed for suspended ceiling mounting. RSH models are shipped with ‘straight-through’
evaporator fan discharge as standard. Fan orientation
is field convertible to side discharge.
Vertical (RSV) units are designed for free-standing floor
mounting. All units are completely factory wired and
pre-piped. Water supply, water outlet, and condensate
drain connections are via flush-mounted female pipe
thread fittings (no back-up wrench required).
CABINET
All cabinets are completely constructed of corrosion
resistant galvanized steel. The RSH units are complete
with integral hanger channels. The entire unit interior
(both evaporator and condensing section) is insulated
with 1/2″ thick, 2 lb density acoustical insulation. Service
panels are equipped with lifting handles for ease of
removal and handling. All units provide service access
to the reversing valve, thermal expansion valve, and
compressor with the unit remaining in location. An integral duct collar is provided on the blower discharge
opening.
REFRIGERATION CIRCUITS
All models utilize high efficiency rotary, hermetic reciprocating or scroll compressors. Compressors are
mounted with rubber isolators on acoustically tuned
bases to minimize vibration transmission. Internal overload protection is provided. External high pressure and
low pressure cutout switches are included in each
compressor control circuit. Each refrigeration circuit
includes an adjustable bi-flow thermal expansion valve
(with external equalizer), bi-flow liquid line filter drier,
and service gauge ports. The reversing valve is a pilot
operated, sliding piston type with a replaceable magnetic solenoid coil.
The refrigerant-to-air heat transfer coils are constructed
of internally enhanced copper tubes mechanically
bonded to enhanced aluminum plate fins. The evaporator coil is employed in a draw-through configuration.
Large evaporator coil face area minimizes potential
water blow-off. A fully-insulated, corrosion resistant
condensate drain pan is provided.
• Optional anti-corrosion protective evaporator coil
coating.
• Optional stainless steel drain pan.
The coaxial refrigerant-to-water heat exchangers feature a convoluted inner tube design for high heat
transfer efficiency. Standard models feature a copper
inner tube surrounded by a steel outer tube, and carry
a 400 psig water side working pressure rating. Units
shall be capable of operation with an entering fluid
temperature range of 20°F to 110°F.
• Optional cupro-nickel condenser water coil.
• Optional condenser insulation package for lowwater temperature, geothermal applications.
INDOOR FAN
Forward curved, double inlet and double width, directdrive centrifugal blowers are used for air movement.
Large diameter wheels are employed to provide required
airflow performance at minimum noise levels. Blower
wheels are fabricated of galvanized steel. Fan motors
are PSC type, with minimum three speeds. The PSC
motors feature permanently lubricated bearings and
internal thermal overload protection.
ELECTRICAL/CONTROLS
All units are completely factory wired with all necessary
operating controls. A 24 volt control circuit, with oversized transformer, is provided for field connection. Units
are designed to operate with conventional heat pump
thermostat control interface. The reversing valve solenoid coil shall be energized in cooling mode only. A
manual reset is provided on each compressor control
circuit in the event of high/low pressure cutout.
• Optional solid-state electronic condensate overflow
switch.
• Optional remote management package allows the
unit to be controlled by an external source.
FILTERS
All models are shipped with 1-inch thick throwaway
filters, factory installed. Filters are accessible from
either side of unit.
FIELD INSTALLED ACCESSORIES
The following options are available field installation:
• 24″ braided stainless steel hose kit with fittings.
(qty 2 hoses per kit)
• Manual isolation ball-valves (600 psi full port).
• Thermostat (programmable or non-programmable)
