CLEARANCES

The clearances listed on the unit dimension drawing (Figure 9) are required for the proper service and opera- tion of the unit.

RIGGING AND HANDLING

Be careful when moving the unit. Do not remove any packaging until the unit is near its final location.

The packaging consists of a bottom wooden skid that can be lifted with a fork truck from any direction, a card- board container that covers the entire unit, and strapping that secures the cardboard container to the bottom of the skid.

These units can be rigged with slings under the bottom skid.

CAUTION: Spreader bars should be used to prevent slings from crushing the unit panels and frame.

Before rigging any unit, determine its weight from Ta- ble 2. Before rigging a unit for horizontal installation, make sure that its weight will be distributed equally.

VERTICAL/HORIZONTAL INSTALLATION

The unit is shipped for vertical installation with a vertical air discharge as shown in Figure 2, but may be converted for horizontal installation as shown in Figure 2 by inter- changing the solid bottom panel and the return air duct flange.

DUCT CONNECTIONS

All ducts should be designed and installed in accordance with applicable national and/or local codes.

Refer to Figure 3 for suggested method of connecting supply air ductwork.

FIG. 3 - SUPPLY AIR DUCT CONNECTION

Ducts should be sized no smaller than the duct flanges on the unit or the accessory electric heater (if used). Ref- er to the unit dimensions (Figure 1) and the heater detail (Figure 4) for these sizes.

Use flexible fiber glass or plastic cloth collars or other non-flammable material at the unit duct connections to minimize the transmission of noise and vibration.

Insulate all ductwork running through unconditioned ar- eas to prevent moisture condensation and to provide more economical operation.

The return air duct flange is factory-mounted on the front of the unit, but it can be reversed with the solid bottom panel for hori- zontal applications. When the return air grille is used, the duct connection frame is not used.

NOTE: If return air duct is not used, applicable lnstalltion codes may limit the unit to installation only in a single story residence.

The field installed air plenum and return air grille accessories should be used in place of ductwork only when a free blow/free return application is practical.

K4EU120A50A, K5EU090A50A specifications

The York K4EU120A50A and K5EU090A50A are high-performance commercial air conditioning units designed for efficiency and reliability. These models integrate advanced technology to meet the demanding cooling needs of various commercial spaces.

One of the primary features of the K4EU120A50A is its high capacity cooling ability, rated at 120,000 BTU, making it ideal for medium to large commercial environments such as office buildings, retail stores, and warehouses. The K5EU090A50A offers a slightly lower capacity of 90,000 BTU, suitable for smaller commercial areas or specific zoned applications within larger buildings. Both units are equipped with energy-efficient compressors that ensure optimal performance while reducing overall energy consumption.

The K4EU and K5EU series utilize variable speed technology, which allows the units to adjust their cooling output based on the space's specific requirements. This feature not only enhances comfort by maintaining consistent temperatures but also contributes to lower operating costs. The inverter-driven compressor technology further enhances energy efficiency by continuously adjusting the cooling output to match the varying demands of the environment.

Both models include advanced air filtration systems designed to improve indoor air quality. The filters capture dust, pollen, and other airborne particles, promoting a healthier atmosphere for occupants. Additionally, the units feature a robust and corrosion-resistant cabinet design, ensuring durability even in harsh conditions.

Installation flexibility is another strong point of the K4EU and K5EU series. These units can be installed in various configurations, including rooftop, ground level, or wall-mounted setups, accommodating different building designs and layouts. The user-friendly control system allows for easy adjustments and monitoring, providing real-time data on performance and energy usage.

The York K4EU120A50A and K5EU090A50A models are also designed with quiet operation in mind. The sound-attenuating components reduce noise levels, making them suitable for environments where noise can be a concern.

In summary, the York K4EU120A50A and K5EU090A50A are distinguished by their high cooling capacities, energy efficiency, advanced technology, and enhanced indoor air quality features. They provide reliable cooling solutions tailored to the needs of commercial users, ensuring comfort and sustainability in a variety of settings.
