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. WAI Installation and repair of this unit should be performed LY by individuals meeting the requirements of an "entry level technician" as specified by the Air-Conditioning, eating and efrigeration Institute (AI). Attempting to install or repair this unit without such background may result in product damage, personal injury or death. WAI oodman will not be responsibile 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. 2

MB0800 MB200 MB600 MB2000 MB200 MB600 MB2000 WAI The United tates nvironmental rotection Agency ( A ) 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. hould questions arise, contact your local A office. WAI 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. WAI Do not connect or use any device that is not design certified by oodman for use with this unit. erious property damage, personal injury, reduced unit performance and/or hazardous conditions may result from the use of such non-approved devices. 3

4 DUCT MB/MB blower cabinets are designed to be used as a two-piece blower and coil combination. MB/MB blower sections can be attached to cased evaporator coil. This two piece arrangement allows for a variety of mix-matching possibilities providing greater flexibility. The MB 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 0.8 inches W.C. external static pressure and includes a feature that allows airflow to be changed by ±%. The MB blower cabinet uses a C motor. It is approved for applications with cooling coils of up to 0. inches W.C. external static pressure. The MB/MB blower cabinets are intended to be used with a cased evaporator coil and a condensing unit or heat pump. The blower section of the cabinet can also be used as an electric furnace. The electric heating elements are field-installed. lectric heater kits (K) are available as sales accessories for supplemental electric heat. The MB/MB blower cabinets with proper coil matches can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units are constructed with -.2 insulation. In areas of extreme humidity (greater than 80% consistently), insulate the exterior of the blower with insulation having a vapor barrier equivalent to ductwork insulation, providing local codes permit. The CAX/CX coils are equipped with a thermostatic expansion valve that has a built-in internal check valve for refrigerant metering. The CACF/CAF/CF coils are equipped with a fixed restrictor orifice. The coils are designed for upflow, counterflow, or horizontal application, using two speed direct drive motors on the CACF/ CAX/CAF/CF/CX models, and BM (Brushless ermanent Magnet) or CM motor on the MB models.

The chart above provides troubleshooting for either version of the encoded thermostat option. This provides diagnostic information for the MC CT8-60 or a conventional two cool / two stage heat thermostat with I00 diodes added as called out in the above section. A test lead or jumper wire can be added from the test terminal to any terminal on the B or B variable speed terminal board and provide information through the use of the LD lights on the B VTB control. Using this chart, a technician can determine if the proper input signal is being received by the encoded VTB control and diagnose any problems that may be relayed to the output response of the B VTM control. xample: The system is calling for st stage cooling operation. The proper input signal from either thermostat option will cause the red + LD light to illuminate when the test terminal and the terminal are connected using a test lead or jumper wire. This verifies proper input from the thermostat. The proper output is a YC signal to the condensing unit. When a test lead or jumper is connected between Test and YC, the red + LD will illuminate. The corresponding response from the CKT control will be an illuminated LW LD light and 2V applied to the Low capacity contactor through the LW terminal output. This similar procedure can be utilized on any terminal on the VTB controls. The chart above indicates the proper input and LD status as well as the corresponding out signal. ach mode of operation must be verified during the check out procedure when the units are installed. The LD light provides a easy method to verify operation without the use of a multi-meter. 27
