Notes:
1. Fouling Factor = 0.00025
2. The off-coil temperature of the hot water coil on parallel fan-powered units must not exceed 140°F.
3. The following equations may be used in calculating Leaving Air Temperature (LAT) and Water Temperature Difference (WTD)
4. Capacity based on 70°F entering air temperature and 180°F entering water temperature. Refer to correction factors for different
entering conditions.
