Shaded boxes represent airflow outside the required 300-450 cfm/ton.
1. Airflow data includes electric heat and filter.
2. Use dry coil data for determining electric heater airflow.
3. Airflow data is with no return grill. When using a return grill on 18 & 24 sizes, decrease numbers above by approx. 10 CFM. For 30 & 36 sizes, decrease numbers above by approx. 50 CFM.
Table 9 – PSC- SELECTING HEAT PUMP SPEED OF PSC MOTOR (Cased, Bottom Return)
- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
1. Airflow data is without filter or electric heat accessory. Heater adds 0.05-in. static.
2. Use wet coil data for determining electric heater airflow.
3. Use wet coil data for determining cooling airflow.
4. Accessory louver panel adds 0.05-in. Static.
