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.

Note: Heating and cooling speeds are the same, factory set at Speed Tap #4.

Note: A “G” only signal from the comfort control will run the blower at a lower speed, factory

set at Speed Tap #1. See the Sequence of Operation for additional information.

Note: Speed Tap 1 is NOT used for two stage systems. Two stage systems will require an

airflow adjustment.

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. If the air handler is applied in downflow or horizontal configurations, the airflow should not exceed 2000 CFM.

Airflow above 2000 CFM could result in water blow-off.
