The York PH3E Packaged Heat Pumps are designed for outdoor installation. Only utility and duct connections are required at the point of installation.

Standard Features:

• Operating Efficiency - All PHE4 heat pump models are rated at 14.0 SEER, 11.0 EER and 8.0 HSPF for cooling and heating operation.
• Operating efficiency: All PH3 heat pump models are rated at 13.4 SEER2 and 6.7 HSPF2 for cooling and heating operation.
• On-site flexibility: All model sizes use a compact design cabinet in one of two footprints. This provides installer flexibility for placing the correct capacity unit on roof curbs, equipment pads, or concrete slabs with the smallest footprint after the internal load has been determined. Field-convertible duct connections from side shot to down shot allow the installer to have greater flexibility with less inventory.
• Lower installation cost: Installation time and costs are reduced by easy power wiring and control wiring connections. The small base dimension means less space is required on the ground or roof. All units are completely wired, charged with R-454B, and tested before shipment. Test stations using a state-of-the-art computerized process system are used to ensure product quality. Refrigerant charge and component part numbers are verified using computer bar code scans during assembly. Vital run test statistics such as system pressures and motor currents are monitored and recorded by the system to ensure unit performance. Equal size side supply and return duct connections allow easy connection of ducts to match low crawl spaces without transition pieces.
• Utility connections made easy: Electric utility access is provided through the bottom or the side of the unit. Utility connections can be made quickly and with a minimum amount of field labor. A field-supplied electrical disconnect switch must be field installed.
• Convertible airflow design: The bottom duct openings are covered when they leave the factory, ready to be used for a side supply and side return application. If a bottom supply and bottom return application is required, remove the two panels from the bottom of the unit and place them in the side supply and side return duct openings. No panel cutting is required and no accessory panel is necessary. The convertible airflow design allows for maximum field flexibility and minimum inventory.
Condensate pan: A corrosion-resistant, long-lasting, watertight pan is positioned below the indoor coil to collect and drain all condensate, preventing build-up of stagnant condensate. The condensate pan conforms to ASHRAE 62-19 standards - Ventilation for Acceptable Indoor Air Quality.
• Condensate drain: The 3/4 in. NPT female connection is rigidly mounted to ensure correct fit and a leaktight seal.
• Durable finish: The cabinet is made of G90 galvanized steel with a powder paint coating for appearance and protection. The pre-treated galvanized steel provides a better paint-to-steel bond, which resists corrosion and rust creep. The powder paint finish ensures less fading when exposed to sunlight, and provides superior corrosion resistance. The powder paint finish is 1,000 h salt spray tested.
• Full perimeter base rails: The easily removable base rails provide a solid foundation for the entire unit and protect the unit during shipment. The rails provide forklift access from all sides, and rigging holes are also provided so an overhead crane can be used to place the units on a roof. On applications where the unit is placed on an equipment pad, the base keeps the unit off the equipment pad to deter corrosion. On applications where height is limited, the base rails can be removed by removing two screws in each corner.
• Attractive appearance: The single-piece top cover contains a top-discharge outdoor fan arrangement. The one-piece design adds greater water integrity. Rounded corners with water drip edges add to the attractive appearance.
• Top discharge: The top-discharge outdoor fan does not disrupt neighboring areas or dry out vegetation surrounding the unit. The warm air from the top-mounted fan is blown up and away from the structure and any landscaping.
• Outdoor coil grille: All models use a stamped slotted design that provides superior impact protection against small objects during transit and after installation.
• Low operating sound level: The upward airflow carries the normal operating noise up and away from the living area. The rigid top panel effectively isolates noise. The isolator mounted compressor and the louvered fins of the outdoor coils muffle the normal fan motor and compressor operating sound. The unique formed base pan also aids in sound attenuation with its structural design.
• Fan system: All models operate over a wide range of design conditions with a standard ECM indoor blower motor. These units easily suit all types of applications and provide greater on-site flexibility to meet comfort requirements. The cooling and heating speeds are factory set at test design conditions but can be field adjusted. This allows for maximum comfort capabilities.
• Loss of charge switch: All models include a loss of charge switch to provide safe shutdown of the compressor.
• Simple control circuit: A printed circuit board contains a status and diagnostic indicator light. Units have a factory installed refrigerant detection system (RDS) and field thermostat wiring connects to the RDS screw terminals. Cooling controls use contactor and relays for simple application and troubleshooting. MATE-N- LOK plug connectors are used. The electrical control box is not located in the compressor compartment. The controls are mounted to allow removal of the separate access panel for troubleshooting and maintenance without affecting the normal system operating pressures. All wiring internal to the unit is color-coded and numbered.
• Protected compressor: The compressor is internally protected against high pressure and temperature. This is accomplished by the simultaneous operation of a high-pressure relief valve and a temperature sensor, which protects the compressor if unsuitable operating conditions occur.
• High-pressure switch: A high-pressure switch is standard in all units. When abnormal conditions are sensed through the high-pressure switch, the unit locks out, preventing any further operation until it is reset or the problem is corrected.
• Exclusive coil design: The grooved copper tubes and enhanced aluminum fin construction of the outdoor coils improve heat transfer for maximum efficiency and durability. Indoor tube and fin coils have all aluminum construction for reliability and efficient heat transfer.
• Low maintenance: Long-life, permanently lubricated indoor blower motor bearings and outdoor fan motor bearings need no annual maintenance, adding greater reliability to the unit. The slide-out blower assembly and indoor coil assembly can be easily removed for cleaning.
• Easy service access: Individual access panels provide access to all major components, for example, the compressor, indoor coil, blower, controls, electric heat kit, and air filters, making servicing easy. Removing these panels allows easy removal of components such as the blower assembly for maintenance and troubleshooting.
• Replacement parts: The installer requires no special training to replace any of the components of these units. The number of new components has been reduced to minimize the inventory of unique parts.
• Controls: Defrost curve options are preloaded into the demand defrost control board for optimized performance based on unit capabilities.
