550.13-TG11Y (0500) SPLIT-SYSTEM EVAPORATOR BLOWER K2ES120A25 10 NOMINAL TONS WITH TWO 5 TON CIRCUITS EER 8.5 DESCRIPTION This completely assembled dual circuit evaporator blower includes a well-insulated cabinet, a DX cooling coil with copper tubes and aluminum fins, two expansion valves, two distributors, throwaway filters, a centrifugal blower, a blower motor, an adjustable belt drive, a blower motor contactor, a 24-volt control circuit transformer and a small holding charge of refrigerant-22. The unit is shipped in the vertical position ready for field installation. For horizontal mounting, reverse the solid bottom panel and the return air duct flange on the front of the unit. This UL approved blower unit with two (2) 5 ton circuits can be applied with the following condensing units: One HCE120 Two HDB048 s Two HDB060 s ACCESSORIES The following accessories are available for field installation: Supply Air Plenum - 1SP0451 This plenum is fully insulated, has double-deflection adjustable grilles, is finished to match the exterior of the blower unit and can be appllied on vertical and horizontal installations. Return Air Grille - 1RG0451 This expanded metal grille is available for a free standing unit located within the conditioned space. It s finished to match the exterior of the blower unit. Hot Water Coil - 1HW0451 This drainable coil is enclosed in a casing that matches the blower unit exterior. It has 2 rows of 1/2" O.D. copper tubes and 8 aluminum fins per inch. The coil slides out of its casing for easy field installation over the return air opening of the blower unit. Steam Coil - 1NF0451 This non-freeze coil is enclosed in a casing that matches the exterior of the blower unit. It has one row of 1" O.D. copper tubes and 8 aluminum fins per inch. Its tube within a tube design provides even distribution of steam across the entire coil. The coil is pitched within its casing to facilitate condensate drainage. The coil slides out of its casing for easy field installation over the return air opening of the blower unit. Base - 1BS0451 This base allows a vertical unit to be elevated above the floor. Outdoor air may be introduced through the base by cutting an access opening to accommodate the outdoor air duct connection. The base is finished to match the blower unit exterior. For detailed information and dimensions on the above accessories, refer to KEU120 data in Form 550.23-TG4Y.

550.13-TG11Y APPLICATION FLEXIBILITY The KES120 is built in a single cabinet with two condensate drain pans. This allows the unit to be installed in either the vertical or horizontal position for maximum flexibility. On vertical applications, the air velocity across the cooling coil keeps the condensate from dripping off the finned surface onto the filters. On horizontal applications, the unit must be installed with the condensate drain pan under the entire cooling coil. The Supply Air Plenum and the Return Air Grille accessories can be used on either arrangement. The Base accessory can only be used on the vertical arrangement. Units installed horizontally are designed for ceiling suspension. Four 3/8" - 16 weldnuts are provided in the angle supports on the front of the unit to accommodate hanger rods. Knockouts are provided in the exterior panels for access to these weldnuts. The hanger rods must be supplied in the field.

Refer to Form 550.13-TG4 for the resistance of these accessories and to the table below for additional motor and drive data. 3 The motor can operate into its service factor because it s located in the moving air stream, upstream of any heating device. Units with steam or hot water coils are the only exception. On these units, the BHP must not exceed the nominal HP rating of the motor.
