BLOWER PERFORMANCE
CFM versus Static Pressure (inches of water column dry coil w/ filter) 4% reduction for wet coil.
The air delivery can be varied by changing the blower speeds. This can allow for differences
encountered in installations.
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)

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.
