1 TECHNICL GUIDE SPLIT-SYSTEM EVPORTOR LOWERS K*ES NOMINL TONS EER 8.5 DESCRIPTION These completely assembled dual circuit evaporator blower units include 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 and a small holding charge of refrigerant-22. The units are shipped in the vertical position ready for field installation. They can be installed for horizontal operation by reversing the position of the solid bottom panel with the return air duct flange on the front of the unit. This CS approved blower unit with two (2) 5 ton circuits can be applied with the following condensing units: One HCE120 Two HD048 s Two HD060 s TLE 1: RI RTINGS* CONDENSING UNIT HCE120 K2ES *Certified in accordance with the Unitary large Equipment certification program, which is based on RI Standard 340/360.

RETURN IR GRILLS These expanded metal grills are available for free standing units located within the conditioned space, are finished to match the exterior of the basic unit and are shipped in one piece for easy installation. SES ISO 9001 Certified Quality Management System ases are available to raise vertical units above the floor. Outdoor air may be introduced through these bases by cutting an access opening to accommodate the outdoor air duct connection. These bases are finished to match the exterior of the basic unit. They may have to be insulated in the field for certain applications. FOR DISTRIUTION USE ONLY - NOT TO E USED T POINT OF RETIL SLE

3 THREE-PHSE ELECTRIC HETERS Electric heaters are available in several capacities to provide maximum flexibility. oth the air conditioning unit and the heater can be selected to precisely match the cooling and heating requirements of the conditioned space. These heaters are designed for easy field installation over the supply air opening of the unit. They have been tested and will be shipped with a CS label. Every heater will be fully protected against excessive current and temperature by fuses and two high limit thermostats. Units with electric heat will require only one power supply for both the heating elements and the supply air blower motor, and the power wiring can be protected by either dual element/time delay fuses or an inverse time circuit breaker. HOT WTER COILS 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 ir Plenum and the Return ir Grill accessories can be used on either arrangement. The ase accessory can only be used on the vertical arrangement. Units installed horizontally are designed for ceiling suspension. Four 3/8"-16 weld nuts are provided in the angle supports on the front of the unit (the side with the logo). Knockouts are provided in the exterior panels for access to these weld nuts. The hanger rods must be supplied in the field. These drainable coils have 2 rows of 1/2" copper tubes, 12 aluminum fins per inch, a casing that is finished to match the exterior of the basic unit, but no water control valve. The coils slide out of their casings for easy field installation. They should be mounted over the return air opening. STEM COILS These non-freeze coils have 1 row of 1" copper tubes, a 5/8" copper tube inside each 1" tube to distribute the steam evenly across the entire length of the coil, 8 aluminum fins per inch, a casing that is finished to match the exterior of the basic unit, but no steam control valve. The coils slide out of their casings for easy field installation and are pitched in their casings to facilitate condensate drainage. They should be mounted over the return air opening. PPLICTION FLEXIILITY MODELS 120 These units are built in a single cabinet with two condensate drain pans. This allows the units to be installed in either the vertical or horizontal position for maximum flexibility. FIGURE 1 - MODEL VERTICL & HORIZONTL POSITION Unitary Products Group 3
