Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. WANING Goodman will not be responsible for any injury or property damage arising from improper service or service procedures. If you install or perform service on this unit, you assume responsibility for any personal injury or property damage which may result. Many jurisdictions require a license to install or service heating and air conditioning equipment. WANING Installation and repair of this unit should be performed ONLY by individuals meeting the requirements of an "entry level technician" as specified by the Air-onditioning, Heating, and efrigeration Institute (AHI). Attempting to install or repair this unit without such background may result in product damage, personal injury or death. WANING The United States Environmental Protection Agency ( EPA ) has issued various regulations regarding the introduction and disposal of refrigerants introduced into this unit. Failure to follow these regulations may harm the environment and can lead to the imposition of substantial fines. These regulations may vary by jurisdiction. Should questions arise, contact your local EPA office. WANING Do not connect or use any device that is not design certified by Goodman for use with this unit. Serious property damage, personal injury, reduced unit performance and/or hazardous conditions may result from the use of such non-approved devices. WANING To prevent the risk of property damage, personal injury, or death, do not store combustible materials or use gasoline or other flammable liquids or vapors in the vicinity of this appliance.

3 PODUT DESIGN GENEAL INFOMATION The MBV Blower abinets are used in combination with a cased evaporator coil for a two-piece blower and coil combination. This combination of blower and coil functions as the indoor part of a split air-conditioning system, and may be matched with a remote condensing or heat pump unit and allows for a variety of mix-matching possibilities. The blower cabinet can also function as an electric furnace when used with an electric heater. NOTE: The electric heating elements for electric furnace installation are not shipped with the cabinet and are fieldinstalled. Electric heater kits (HK) are available as sales accessories for supplemental electric heat. Systems should be properly sized by heat gain and loss calculations made according to methods of the Air onditioning ontractors Association (AA) or equivalent. It is the contractor s responsibility to ensure the system has adequate capacity to heat or cool the conditioned space. The MBV blower cabinet uses a variable speed motor that maintains a constant airflow with a higher duct static. It is approved for applications with cooling coils of up to 0. inches W.. external static pressure and includes a feature that allows airflow to be changed to + 0%. The MBV blower cabinets, with proper coil matches, can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units are constructed with -. insulation. In areas of extreme humidity (greater than 0% consistently), insulate the exterior of the blower with insulation having a vapor barrier equivalent to ductwork insulation, providing local codes permit. The APX/HPX coils are equipped with a thermostatic expansion valve that has a built-in internal check valve for refrigerant metering. The AF/APF/HPF coils are equipped with a fixed restrictor orifice. The coils are designed for upflow, counterflow, or horizontal application, using EM motors on the MBV models. FEATUES This modular blower is a part of the omfortnet family of products. It may be installed as part of a legacy system using a standard VA thermostat. However, with the TK0AA omfortnet thermostat kit, this modular blower may be installed as part of a digitally communicating system. The omfortnet system provides automatic airflow configuration, enhanced setup features, and enhanced diagnostics. It also reduces the number of thermostat wires to a maximum of four. OMFOTNET SYSTEM OVEVIEW The omfortnet system (or T system) is a system that includes a omfortnet compatible modular blower and air conditioner or heat pump with a TK0AA thermostat. Any other system configurations are considered invalid omfortnet systems and must be connected as a traditional (or legacy) system. The table below compares the valid T systems. T compatible Modular Blower T compatible Modular Blower T compatible Air onditioner T compatible Heat Pump Full T system benefits & features Full T system benefits & features A omfortnet heating/air conditioning system differs from a legacy/traditional system in the manner in which the indoor unit, outdoor unit and thermostat interact with one another. In a traditional system, the thermostat sends commands to the indoor and outdoor units via analog VA signals. It is a one-way communication path in that the indoor and outdoor units typically do not return information to the thermostat. On the other hand, the indoor unit, outdoor unit, and thermostat comprising a omfortnet system communicate digitally with one another. It is now a two-way communications path. The thermostat still sends commands to the indoor and outdoor units. However, the thermostat may also request and receive information from both the indoor and outdoor units. This information may be displayed on the T thermostat. The indoor and outdoor units also interact with one another. The outdoor unit may send commands to or request information from the indoor unit. This two-way digital communications between the thermostat and subsystems (indoor/outdoor unit) and between subsystems is the key to unlocking the benefits and features of the omfortnet system. Two-way digital communications is accomplished using only two wires. The thermostat and subsystem controls are powered with VA Thus, a maximum of wires between the equipment and thermostat is all that is required to operate the system.
