This can allow for differences encountered in installations. The CFM can be checked by the following method; (The optional Heat Kit must be installed to continue with this procedure.) 1) All access panels must be in place. 2) Start the unit in the heat mode. 3) Measure the return air temperature. 4) Measure the supply temperature. This measurement should be done in various locations to obtain an average. 5) Subtract the return temperature from the supply temperature. This is referred to as the temperature rise. 6) Measure the actual supply voltage and actual amperage at the terminal block/circuit breaker. 7) The BTUH output = (Voltage x Amps x 3.41) output (BTUH) CFM = 1.08 X temperature rise Should the CFM need to be increased or decreased it may be done by adjusting the blower speed tap as shown on the wiring diagram. 14
