INSTALLATION INSTRUCTIONSMODULAR BLOWER: MVSEQUENCE OF OPERATIONMV modular blower will supply airflow in a range which is morethan twice the range of a standard modular blower. Each modularblower size is designed to provide nominal cooling capacities at50 _F evaporator temperature and the required airflow in order tomatch with any of four (4) different air conditioner or heat pumpoutdoor unit sizes. Table 2 outline the CFM range for the differentMV modular blowers.The blower motor is a true variable speed motor designed todeliver constant CFM. Constant CFM is valid for systems withtotal external static pressure between 0.1 and 0.7 inches watercolumn.A.. CONTINUOUS FANS Thermostat closes circuit R to G.SBlower runs at continuous fan airflow.B. COOLING MODE - SINGLE STAGESNOTE:SIf indoor temperature is above temperature set point andhumidity is below humidity set point, thermostat closescircuits R to G, R to Y/Y2 and R to O.For single stage systems, do not use the Y1terminal.Modular blower delivers single stage cooling airflow.C. COOLING MODE - TWO STAGESSSSFirst stage (low) cooling: Thermostat closes circuits to R toG, R to O, and R to Y1.Modular blower delivers low stage cooling airflow.Second stage (high) cooling: Thermostat closes circuits toRtoG,RtoO,RtoY1andRtoY/Y2.Modular blower delivers high stage cooling airflow.D. ELECTRIC HEAT HEATING MODES Thermostat closes circuit R to W/W1, or W2.SModular blower delivers the selected electric heat airflow.E. HEAT PUMP HEATING MODE - SINGLE STAGESNOTE:Thermostat closes circuits R to G and R to Y/Y2.For single stage systems, do not use the Y1terminal.S Modular blower delivers single stage heat pump heatingairflow.F. HEAT PUMP HEATING MODE - TWO STAGESFirst stage (low) heating: Thermostat closes circuits R to Gand R to Y1.If the thermostat calls for electric heat when the heat pump isoperating in heating or defrost, the motor will modify the airflow ifnecessary. The motor will provide an airflow which is safe for theoperation of the electric heat. That airflow is the greater of the heatpump heating airflow and the electric heat only airflow.! CAUTIONELECTRICAL SHOCK or UNIT DAMAGE HAZARDFailure to carefully read and follow this CAUTIONwarning could result in equipment malfunction,property damage, personal injury and/or death.Disconnect power to unit before removing or replacingconnectors or servicing motor. Wait at least five(5) minutes after disconnecting power before openingmotor.CARE AND MAINTENANCEThe system should be regularly inspected by a qualified servicetechnician. Consult the servicing dealer for recommendedfrequency. Between visits, the only consumer servicerecommended or required is air filter maintenance andcondensate drain operation.AIR FILTERInspect air filters at least monthly and replace or clean asrequired. Disposable type filters should be replaced. Reusabletype filters may be cleaned by soaking in mild detergent andrinsing with cold water. The frequency of cleaning depends uponthe hours of operation and the local atmospheric conditions.Install filters with the arrows on the side pointing in the directionof air flow. Clean filters keep unit efficiency high.LUBRICATIONThe bearings of the blower motor are permanently lubricated.CONDENSATE DRAINSDuring the cooling season check the condensate drain lines to besure that condensate is flowing from the primary drain but notfrom the secondary drain. If condensate ever flows from thesecondary drain, the unit should be promptly shut off and thecondensate pan and drains cleaned to insure a free flowingprimary drain.SSModular blower delivers low stage heating airflow.Second stage (high) heating: Thermostat closes R to G, Rto Y1 and R to Y/Y2.SModular blower delivers high stage heating airflow.G.
