HBX0-120 Series DX / Heat Pump Efficiency: The HBX0-120 series air handler is the latest state-of-the-art air handler for heat pump or straight cool (DX) operation. Depending on the condensing unit or heat pump used, cooling efficiency is up to 14 SEER (depending on the selected outdoor unit). Cooling coils have either piston type metering devices, or R22 or R410a TXV s and are circuited for cooling or heat pump operation. First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor unit(s) and which expansion valves (if any) are required. To determine approved indoor/outdoor matches, go to: www.firstco.com or contact the factory Components: Each air handler includes a high efficiency cooling coil, 120V fan motor, 24V transformer, horizontal drain pan, and throw away filter. Cabinets: Cabinets are fully insulated. Installation: No modification is required for vertical or horizontal (right-to-left) airflow. A horizontal drain pan is factory installed for right-to-left airflow and can be re-positioned within the cabinet to offer left-toright airflow. Accessories: Accessories include cooling / heat pump TXV kits. (See page 4) 3-WAY AIRFLOW -2-

"VARIABLE SPEED" V_HBX Series Variable Speed 1.5-5.0 Tons Cooling and Heat Pump 0-25kW Electric Heat Upflow / Horizontal The V_HBX series includes a programmable, high efficiency motor that redefines comfort and energy savings. The V_HBX motor automatically adjusts its torque and speed to maintain a pre-programmed level of constant airflow over a wide range of external static pressures. This variable speed technology offers better indoor air quality, more precise humidity control, quieter operation, consistent indoor air temperature, and lower utility bills High Efficiency - At full load conditions the V_HBX motor is 20% more efficient than an induction motor and at constant fan speed it consumes only 60-80 watts of power compared to 400 watts for a standard induction motor. In addition, the V_HBX includes a high efficiency "A" coil with factory installed TXV for precise refrigerant control in either cooling or heat pump mode. (1) First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor unit(s) and which expansion valves are required. To determine approved indoor/outdoor matches, go to www.firstco.com or contact the factory. VOHBX Model - Reversing valve energizes in cooling mode VBHBX Model - Reversing valve energizes in heating mode Variable Speed Motor Quiet Operation - The versatile V_HBX motor quietly "ramps up" when the unit is turned on and "ramps down" when the thermostat is satisfied, eliminating the annoying sounds of changing airflow. Self-Regulating Constant Airflow - The V_HBX motor is factory programmed to maintain a predetermined level of airflow over a wide range of external static pressures, ensuring optimum system performance and whole-house comfort. The benefits of constant fan operation are: Consistent air distribution (and temperature) throughout the home Better indoor air quality (further improved with the addition of a high efficiency filter) - This allows the air to be filtered without excessive drafts and without sacrificing efficiency. Better humidity control - The V_HBX is designed to extract much more moisture from the air than a conventional system by slowing the airflow over the cooling coil. The result is an improved summer comfort level at higher indoor temperatures. Additional Standard Features Factory installed R22 or R410a TXV (cooling or heat pump operation) Factory installed electric heat (0-25kW) 208/240V motor Upflow / horizontal drain pans Higher efficiency pleated filter Factory installed disconnect switch (over 10kW) Compatible with major brands of split condensing units or heat pumps Primary and secondary drain connections on cooling coil Insulated cabinet with baked-on powder coat finish Compatible with most properly sized and installed zone control systems.
