MECHANICAL SPECIFICATIONS

GENERAL

Units shall be manufactured by York International Unitary Products Group in an ISO 9001 certified facility. YORK’s Champion® package units are designed to handle applica- tions ranging from residential to light commercial and any in between. The Champion® is a unit that gives you the flexibil- ity and choices you need in today’s market. These packaged cooling/heating air conditioners are designed for outdoor installation. Only utility and duct connections are required at the point of installation. The gas fired heaters have alumi- nized steel tubular heat exchangers and hot surface to pilot ignition. They are available in natural gas with field conver- sion to propane.

DESCRIPTION

Units shall be factory-assembled, single packaged, Electric Cooling/Gas Heating units, designed for outdoor mounted installation. For SEER ratings, refer to technical literature. They shall have built in, equal size, field convertible duct con- nections for down discharge supply/return or horizontal dis- charge supply/return. The units shall be factory wired, piped, charged with R-22 refrigerant and factory tested prior to ship- ment. All unit wiring shall be both numbered and color coded. All units shall be manufactured in a facility certified to ISO 9001 standards, and the cooling performance shall be rated in accordance with DOE and ARI test procedures. The heat- ing performance shall be rated to DOE and GAMA test proce- dures. Units shall be CSA listed and classified to ANSI22.47. CAN/CGA2.3 standards and UL 1995/CAN/CSA No. 236- M90 conditions.

UNIT CABINET

Unit cabinet shall be constructed of G90 galvanized steel, with exterior surfaces coated with a non-chalking, powdered paint finish, certified at 750 hours salt spray test per ASTM- B117 standards. The unit top shall be a single piece “Water Shed” design, with drip edges and no-seam corners to pro-

vide optimum water integrity. Unit shall have a rigidly mounted condenser coil guard to provide protection from objects and personnel after installation. Indoor blower section shall be insulated with up to 3/4” thick, aluminum, foil faced insulation, fastened to prevent insulation from entering the air stream. Cabinet panels shall be “large” size, easily remov- able for servicing and maintenance, with built-in lift handles. Unit shall be built on a formed, “Super-Structure” design base pan, with embossments at critical points to add strength, rigidity and aid in minimizing sound. Full perimeter base rails shall be provided to assure reliable transit of equipment, overhead rigging, for truck access and proper sealing on roof curb applications. Base rails shall be removable, when required, to lower unit height. Filters shall be furnished and be accessible through a removable access door, sealed air- tight. Units vertical discharge and return duct configuration shall be designed to fit between standard 24” O.C. beams without modification to building structure, duct work and base unit. Condensate pan shall be internally sloped and conform to ASHRAE 62-89 self-draining standards, with 3/4” NPTI copper, ridged mount connection.

INDOOR (EVAPORATOR) FAN ASSEMBLY

Fan shall be direct drive, multi-speed design. Job site selected (BHP) brake horsepower shall not exceed the motors nameplate horsepower rating. Fan wheel shall be double-inlet type with forward-curved blades, dynamically balanced to operate smoothly throughout the entire range of operation. Airflow design shall be constant air volume. Bear- ings shall be sealed and permanently lubricated for longer life and no maintenance. Fan assembly shall be “Slip Track” (slide-out) design for easy removal and cleaning.

OUTDOOR (CONDENSER) FAN ASSEMBLY

The outdoor fan shall be of the direct-driven propeller type, discharge air vertically, have aluminum blades riveted to cor- rosion resistant steel spider bracket and shall be statically balanced for smooth operation. The outdoor fan motor shall be totally enclosed with permanently lubricated bearings and internally protected against overload conditions.

DNH018 specifications

The York DNH018 is a highly efficient ductless mini-split heat pump system well-regarded in the HVAC industry for its innovative features and impressive performance. This unit is designed to provide both heating and cooling, making it a versatile choice for a variety of residential and light commercial applications.

One of the main features of the York DNH018 is its energy efficiency. With a Seasonal Energy Efficiency Ratio (SEER) rating that exceeds many traditional systems, this mini-split model serves to reduce energy consumption and lower utility bills. Its high efficiency is complemented by an impressive Heating Seasonal Performance Factor (HSPF), which ensures optimal performance even in colder climates.

The technology behind the York DNH018 is cutting-edge. It utilizes inverter technology that allows the compressor to adjust its speed according to the heating or cooling demand. This results in a more consistent temperature and improved comfort levels. Inverter systems provide quieter operation and enhance the lifespan of the equipment by reducing wear and tear compared to traditional systems that constantly turn on and off.

Another characteristic of the York DNH018 is its compact and sleek design. The outdoor unit is designed to take minimal space while still delivering powerful performance. The indoor unit is available in various styles, including wall-mounted and ceiling cassettes, allowing for flexible installation options that can blend seamlessly into a variety of room aesthetics.

The system also includes advanced filtration technology that helps improve indoor air quality by reducing allergens and contaminants in the air. Many models come with a multi-stage filter system that captures dust, pollen, and other particles, promoting a healthier living environment.

Moreover, the York DNH018 offers user-friendly controls. Many units come equipped with programmable thermostats and remote control options, enabling users to manage their indoor climate efficiently. Some models even feature Wi-Fi connectivity, allowing for smartphone integration for remote temperature management.

In summary, the York DNH018 combines energy efficiency, innovative technology, and superior design to deliver reliable heating and cooling solutions. Its advanced features and flexible installation options make it an ideal choice for those looking for an effective temperature control system.
