ABN MNXIDE ISNIN HAZA Special Warning for Installation of Furnace or Air Handling Units in Enclosed Areas such as arages, Utility ooms or arking Areas arbon monoxide producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide () poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation. This ventilation is necessary to avoid the danger of poisoning which can occur if a carbon monoxide producing device continues to operate in the enclosed area. arbon monoxide emissions can be (re)circulated throughout the structure if the furnace or air handler is operating in any mode. can cause serious illness including permanent brain damage or death. B ENEAL INFMATIN The MB/MBE Blower abinets are used in combination with a cased evaporator coil. 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. The blower cabinet can also function as an electric furnace when used with an electric heater. NTE: The electric heating elements for electric furnace installation are not shipped with the cabinet and are field-installed. 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.

3 LEAANES AND AESSIBILITY The unit can be positioned for upflow, counterflow, horizontal right or horizontal left operation. Zero clearance is allowed on all sides for combustible materials. Thirty-six inches should be allotted on the door side for maintenance and service. To reduce risk of rusting, do not install the unit blower directly on the ground or on a floor that is likely to be wet. In such environments, the unit must be elevated by use of a sturdy, nonporous material. INSULATIN To ensure efficient operation, review the following precautions. If the unit is located in an area with high ambient temperature and/or high humidity, the air handler may be subject to nuisance sweating of the casing. n these installations, a wrap of 2 fiberglass insulation with a vapor barrier is recommended. The factory recommends insulating the duct running through any unconditioned spaces. To reduce operating sound and vibration transmission use flexible canvas duct connections at the cabinet.

(Insulated crimp type connectors, field supplied, may be substituted for the wire nuts and electrical tape provided proper size connectors are used.) A ground wire MUST be connected to the ground lug inside the unit. LW VLTAE WIIN Low voltage wiring connections are made at the top of the cabinet. See the Thermostat Wiring section of this manual for typical low voltage wiring connections. A minimum 8 AW wire must be used for installations up to 0 feet and 6 AW wire for installations over 0 feet. MISELLANEUS ELETIAL The unit transformer is factory connected for 20 V operation. If unit is to operate on 208 V, disconnect the red wires from terminal 3 of the unit transformer and connect them to terminal 2 of the unit transformer. INSTALLE: It is important to follow these instructions when installing the MB series of air handlers. THEMSTAT NNETINS The following composite wiring diagrams detail various configurations in which your MB air handler can be used. Examples include single stage cooling, two stage cooling and heat pump with single or two stage electric heating. All these configurations can be applied with convenient connections to outdoor thermostat applications. The following sections will be detailed: Single Stage ooling (M Thermostat part # HT8-60 or equivalent) Heat ump (M Thermostat part #HT8-60 or equivalent) Two Stage ooling with onventional Two Stage Thermostat (M Thermostat part #HT90-20 or equivalent) Two Stage ooling with onventional Two Stage Thermostat (Encoded with Add-on Diodes) Two Stage Encoded Thermostat from oodman Manufacturing art #HET8-60 Each diagram details the connections between room thermostat and MB air handlers, and the connections between the MB air handlers and the ondensing Unit (or Heat ump) with optional connections to utdoor Thermostats. For each configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result in the programmed EM TM motor on MBE units. Important: When matching the MBE air handlers to a single stage cooling unit or heat pump, remember to connect the Y/ Y2 thermostat connection on the Variable speed board (VSTB) to the thermostat. onnecting will result in first stage cooling blower speed. Note: The two stage configurations are illustrated to detail connections to the two capacity condensing units and heat pumps. An equivalent thermostat can be used in place of the oodman thermostat part number. The M thermostats listed are mercury type. When utilizing the encoded version of a conventional two stage cooling and heating electronic thermostat (add-on diodes), a hard wire (common of 2V secondary voltage) must be used. This encoded version will not work with a power robbing thermostat (i.e. no common connection). ne TSTWK0 kit is required for the encoded applications on MBE units. NTE: When using a conventional two stage thermostat for cooling or heat pump applications with a two stage compressor, dip switch # must be set to the FF position on MBE units. MBE MT This section references the operation characteristics of the MBE model motor only. The EM control board is factory set with the dipswitch # in the N position and all other dipswitches are factory set in the FF position. For most applications, the settings are to be changed according to the electric heat size and the outdoor unit selection. The MBE product uses a eneral Electric EM TM motor. This motor provides many features not available on the traditional S motor. These features include: Improved Efficiency onstant FM Soft Start and Stop Improved Humidity ontrol MT SEED ADJUSTMENT Each EM blower motor has been preprogrammed for operation at distinct airflow levels when operating in ooling/ Heat ump mode or Electric Heat mode. These distinct levels may also be adjusted slightly lower or higher if desired. The adjustment between levels and the trim adjustments are made by changing the dipswitch(s) either to an "FF" or "N" position. SWITH FUNTINS The MBE air handler motor has an electronic control that contains an eight (8) position dip switch. The function of these dipswitches are shown in Table.

This provides diagnostic information for the M HET8-60 or a conventional two cool / two stage heat thermostat with IN00 diodes added as called out in the above section. 22

23 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 LED lights on the B VSTB control. Using this chart, a technician can determine if the proper input signal is being received by the encoded VSTB control and diagnose any problems that may be relayed to the output response of the B VSTM control. Example: The system is calling for st stage cooling operation. The proper input signal from either thermostat option will cause the red + LED light to illuminate when the test terminal and the S terminal are connected using a test lead or jumper wire. This verifies proper input from the thermostat. The proper output is a YN signal to the S condensing unit. When a test lead or jumper is connected between Test and YN, the red + LED will illuminate. The corresponding response from the KTS control will be an illuminated LW LED 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 VSTB controls. The chart above indicates the proper input and LED status as well as the corresponding out signal. Each mode of operation must be verified during the check out procedure when the units are installed. The LED light provides a easy method to verify operation without the use of a multimeter. 23
