YORK YD360 Split System Air Cooled Condensing Units

Product Information

Description

The YD360, 480, and 600 models are split-system air-cooled condensing units that have a cooling capacity of 30-50 tons. These units are delivered fully assembled, wired, and piped at the factory, allowing for easy shipping and rigging. The fan guards are vinyl-coated for rust protection and to enhance the unit’s appearance. The compressors are mounted on rubber isolators to reduce noise and vibration transmission. The condenser fans direct sound upward and away from surrounding structures. All sheet metal parts are made from commercial-grade galvanized steel and coated with powder paint to maintain a quality finish for years.

• These units are completely assembled, piped and wired at the factory to provide one-piece shipment and rigging. Each unit is pressurized with a holding charge of nitrogen for storage or shipping.
• The compact design, clean styling, low silhouette, and quiet operation make these condensing units suitable for almost any outdoor location. They are suitable for rooftops, because they weigh much less than a single package unit of similar capacity and are much easier to rig and support and also can be located at ground level, because their ample sub-cooling capacity allows them to be located three or more stories below the evaporator coil.
• Every condenser coil is pressurized with air to 325 psig and leak tested. After assembly, the unit is pressure tested to 450 psig and additional leak testing is done. During this pressure test, the operation of the high pressure control is checked. As the unit is being evacuated and dehydrated, the operation of the low pressure control is checked.
• Every compressor, condenser fan motor, crankcase heater, and elec-trical control circuit is checked to assure a trouble-free start-up and years of reliable operation.
• The condenser fan guards are vinyl-coated to provide additional rust protection and to enhance the appearance of the unit.
• Compressors are mounted on rubber isolators to reduce the transmis-sion of vibration. Vertical discharge condenser fans direct sound upward and away from any surrounding structures.
• All sheet metal parts are constructed of commercial grade galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces.
• The external parts are coated with a powder paint to assure a quality finish for many years. This UL approved coating system has passed the 750-hour, 20% salt spray test per ASTM Standard B117.
• All models include a 1-year limited warranty on the complete unit. An additional 4-year extended compressor warranty is available as an option on all models.
• A matching line of evaporator blower units is also offered to meet your precise capacity and air handling requirements.

Condensing unit features and benefits

• Meets or exceeds ASHRAE 90.1 standards.
• Scroll compressors provide both high efficiency and reli-ability.
• Smart Equipment™ Controls
• Dual refrigerant circuits.
• Condenser coils are constructed of copper tubes and aluminum fins for durability and long lasting efficient operation.
• Crankcase heaters that will be de-energized when the compressor is operating.
• Both high and low pressure controls. Since these con-trols are self-contained, there are no capillary lines to be damaged.
• Solid state or internal line break compressor motor pro-tection.
• Class 2, 24-volt thermostat control circuit.
• Factory installed service valves are standard.
• Two filter-driers are shipped in the unit’s control box for field installation in the liquid line near the condensing unit.
• Copper stub-outs are factory mounted on the suction and liquid line service valves to simplify the field piping connections.
• Multiple controls to provide stable system operation at ambient temperatures down to 40ºF with kits available for operation to 0ºF.
• Capacity staging for more economical operation and more even temperature levels within the conditioned space.
• A lockout circuit to prevent the unit from cycling on safety control.
• Pump-out on unit startup to prevent liquid refrigerant returning to the compressor is standard on all models.
• Inherently protected condenser fan motors.
• V-Coil Design with exterior service port connections.
• Five-minute anti-short cycle timer and minimum com-pressor run time.
• Factory installed disconnect and Technicoat coils option.
• Self contained high and low pressure controls.

Condensing unit accessories

• Low ambient VFD control to 0° F.
• Phase Monitors – Designed to prevent unit damage. The phase monitor will shut the unit down and out-of phase condition.
• Hot Gas Bypass Kit – That will provide a metered flow of compressor discharge gas to the system’s evaporator coil during reduced load operation.
• Optional skid for fork truck handling (requires 96” length forks).

Warranty

All models come with a 1-year limited warranty on the complete unit. An optional 4-year extended compressor warranty is also available on all models.

Product Usage Instructions

Note : Typical field wiring when OD unit is matched with ND air handler. When matching condensing unit with models other than ND an additional control transformer is required on the Indoor unit.
Note : For applications on air handlers/evaporator DX coils other than ND360-600 certified matchups liquid line solenoids may be required for proper operation and refrigerant system dump out.
