SUBMITTAL REVIEW
1. Review the unit submittal (see Fig. H.) and record the follow-
ing information for the supply fan and exhaust fan (if
equipped):
• Design airflow, design external static (duct static, not in-
cluding unit options)
• Fan RPM
• Motor BHP, Motor FLA
2. Review the factory installed options from the unit model
number (last 2 digits) to confirm the supply fan and exhaust
fan (if equipped) control method (see Table 1 and Table 3).
Available options include:
• Constant speed (no airflow option).
• Pressure control (duct pressure for supply fan [SF-DPT],
space pressure for exhaust fan [Zn-DPT], if equipped).
• Airflow monitor control for supply fan and exhaust fan (if
equipped).
• Blanket quote ETO for supply fan space pressure control is
also available and would show on the unit submittal.
NOTE: the supply and exhaust fans cannot be controlled to the
same sensor.
3. Review fan control methodology with customer to confirm
operation.
