3 Horizontal Direct Drive Units 00 to 3000 CFM Versatile Units These compact blower coils are ideally suited for a variety of ducted applications that require a range of 00 to 3000 CFM, capacities between.5 tons to 0 tons, and generally rated for applications with w.g. or less of external static pressure, but can be operated at higher ESP - contact factory for additional information. These units provide comfort cooling and heating while offering a broad range of application flexibility between the traditional fan coil unit and a central station air handling unit. Several configurations are available to meet the needs of different climates and applications. The HDY units can be ordered as a: -pipe system -pipe system with electric heat -pipe system Direct expansion system cooling Direct expansion cooling with electric heat Direct expansion cooling with hot water heating Multitude of Applications These units are ceiling mounted, and available with a variety of options that can meet the design requirements, and provide a low cost solution for a multitude of applications.

4 Standard Horizontal Direct Drive Blower Coil Applications Where the application calls for cooling capacities or external static pressures that can not be met with standard or high performance direct drive fan coil units; use an IEC horizontal direct drive blower coil. Outside Air Applications With the availability of larger capacities, a variety of optional coils, mixing boxes, and the capability of delivering air through long duct runs, the direct drive units are ideal for handling outside air. When used as outside air units, the heating coil should be in the pre-heat location (consult factory). Operating Limitations Fan curves define the recommended airflow and static pressure ranges of operations. Running the HDY units outside this range could lead to drastically reduced bearing life and premature wheel failure. In cooling applications, this could also result in moisture carry over. In addition, running the fan at its maximum fan speed will increase the power requirements and generate higher sound levels. On units with electric heat, the minimum airflow shown on the fan curve must be maintained to prevent excessive discharge temperature and electric heat safety trips. Large Public Areas These units are ideal for applications with a large common area such as restaurants, airports, sports arenas, stadiums, private boxes, gymnasiums, exercise areas, locker rooms, atriums and foyers, auditoriums, shopping malls, equipment or mechanical rooms, and casinos, to name a few. Installation Considerations The HDY units are typically suspended above the ceiling. Attention should be paid to having enough clearance around the units for service and maintenance. Horizontal units are generally suspended above the ceiling using hanger rods that go through the corner knock-outs provided in the units. External vibration isolation and flex connections for ducts are recommended. Acoustical Considerations With sound becoming more of a concern to design engineers, building owners, and occupants, proper consideration should be given to the selection and placement of these units. Whenever possible, avoid placing these units above an occupied space. To further reduce the sound level, additional measures such as: using flexible duct connectors; lining the main supply and return ducts with acoustical absorption material; locating the return air grilles as far away from the unit as possible; and using 3-phase motors.

21 Electric heaters are available on IEC Direct Drive blower coils for total electric heat. Total Electric Heat Total electric heat eliminates the requirement for a boiler and provides heating and/or cooling on an individual basis throughout the year. Electric heat is available only for single source power (motor and heater voltage the same). Heater Construction The heater coils of high-grade resistance wire are supported by ceramic insulators on plated steel brackets. These heat elements are suspended directly in front of the outlet after the blower and the coil. An auto and a manual thermal limit switch protect the heater in the event of airflow failure. For electric heat control options refer to page 35. Electric Heater Selection kw Heater Availability Full Load Amps Single Phase Three Phase 0 0/ 30 5 V 0 V 30 V 77 V 0 V 30 V 0 V NOTES:. Electric heaters are available for -stage, -stage or 3-stage applications depending on power phase and heater kw. SINGLE-PHASE POWER: - kw: -stage available 3- kw: -stage available 3-PHASE POWER: -35 kw: -stage available -35 kw: -stage available -35 kw: 3-stage available. Electric Heating Capacities (BTUH) = Heater kw x Electric Heater Amperage for Single-phase Power = (Heater kw x 000)/Applied Voltage Electric Heater Amperage for 3-phase Power = (Heater kw x 000)/(Applied Voltage x.73)

22 Thermal Overload Protection All standard motors on Horizontal Direct Drive units furnished by IEC contain internal thermal overload protection. The overload automatically resets when the temperature returns to a safe limit. These thermal overloads replace the need for motor starters.

33 Distributed Weight Calculations The following operating weight information is based on -row water-filled coils and double wall cabinet construction. For a different coil and cabinet options, use the weight correction factor table. Horizontal Units (Top View) HDY Unit No Electric Heat (lb.) With Electric Heat (lb.) A B C D Total A B C D Total Total Weight Unit Correction Factor (lb.) HDY These weights are for -row water-filled coils and double wall construction. For a different number of rows, total unit weight can be determined by: Total unit weight can be adjusted by : a. Identify the size of unit and number of rows b. From the previous table, identify the total weight of the unit c. From the table below, identify the correction factor and deduct this factor from the total weight. Options Row Coil Row Coil Row Coil Row Coil Single Wall Construction NOTE:. Unit weights (shown in pounds), +/- 0 percent, are based on the largest water-filled coil. 33

35 Factory Installed Options Controls: Motor Controls Units without electric heat: Two controls schemes are available: 3 - Speed adjustable. Proportional (0-0 VDC). Electric Heat Controls Electric heaters come standard with a transformer, heater contactors, motor and electric heat fusing, and a terminal strip. Condensate Float Switch A water-level sensing device designed to prevent drain pan overflow. The standard switch is wired normally closed. Switches are available only in V. Cabinet/Control Box Maintenance Light Optional LED Service Light provides a source of illumination in the main unit cabinet and the control box during routine maintenance and troubleshooting in the dark ceiling spaces. An optional interlocking disconnect switch is available. Control Box Above picture is the example of Control box with electric heat, disconnect switch and service light. 35

36 Mixing Boxes Mixing boxes can be used when outside air is required. Mixing boxes come with base rails. Refer to the drawings on pages 3 and 37 for additional information. Mixing Box with Base Rails Mixing box option includes :.) knockdown base rails for field assembly, and.) pre-assembled mixing box. Base rails are letter coded for ease of assembly and all hardware required for assembly is included. Linkage kit consists of crank arms, swivels, and either a 5" (sizes 0-) or a 3" (sizes 0-30) length of 5/" rod provided for field installation of actuator. Consult factory for the V damper actuator option. Mixing box option adds 3" to the unit height due to the base rails.
