Air deliveries based on unit dry coil without air filter or optional electrical heaters. Deduct field supplied air filter and electric heater pressure drop to
obtain external static pressure available for ducting. Dashes indicate less than minimum airflow and coil icing may occur.
tAirflow exceeds maximum coil velocity. Condensate may be blown off of coil.
If supplemental electric heaters are used, refer to Table 5 for minimum air-flows. These airflows will be slightly greater than those required for unit
operation.
