NOTES:
1. Values are with wet coil and without filters.
2. Contact your particular filter manufacturer for pressure drop data.
3. Electric heater pressure drop is negligible and is included within the airflow data.
4. Tap 1 is an continuous fan speed tap for single stage systems. Airflow adjustment is required for 2 stage systems.
See Airflow adjustment section.
5. † Factory Setting
Note: Heating and cooling speeds are the same, factory
set at Speed Tap #4.
