246813-YTG-D-010810 Unitary Products GroupFILTER PERFORMANCEThe airflow capacity data published in the “Blower Perfor-mance” table listed above represents blower performanceWITHOUT filters. To determine the approximate blower per-formance of the system, apply the filter drop value for the fil-ter being used or select an appropriate value from the “FilterPerformance” table shown.NOTE: The filter pressure drop values in the “Filter Perfor-mance” table shown are typical values for the type of filterlisted and should only be used as a guideline. Actual pres-sure drop ratings for each filter type vary between filter manu-facturer.APPLYING FILTER PRESSURE DROP TODETERMINE SYSTEM AIRFLOWTo determine the approximate airflow of the unit with a filter inplace, follow the steps below:1. Select the filter type.2. Select the number of return air openings or calculate thereturn opening size in square inches to determine theproper filter pressure drop.3. Determine the External System Static Pressure (ESP)without the filter.4. Select a filter pressure drop from the table based uponthe number of return air openings or return air openingsize and add to the ESP from Step 3 to determine thetotal system static.5. If total system static matches a ESP value in the airflowtable (i.e. 0.20, 0.60, etc,) the system airflow corre-sponds to the intersection of the ESP column and Model/Blower Speed row.ACCESSORIESPROPANE (LP) CONVERSION KIT -1NP0680 - All unitsThis accessory conversion kit must be used to convert natu-ral gas (N) units for propane (LP) operation.
