Notes:
1. Maximum air temperature rise of 40°F (22.2°C) must not be
exceeded.
2. See Electric Heater Availability table for various unit sizes.
3. Air temperature rise is for total heating capacity: Temperature rises
at other conditions may be calculated by using the formula:
Temperature Rise = Output Capacity - BTU/h
1.08 x ft³/min. Airfl ow
Note: Temperature rises must be calculated in other than nominal volt-
age conditions.
4. For altitudes over 2,000’, air temperature rise must be calculated
using the formula:
Temperature Rise = Output Capacity - BTU/h
14.4 x ft³/Min. Airfl ow x Specifi c Weight of Air
5. Operation at less than nominal voltages must be de-rated by the
following factors: 415 volt-0.75; 380 volt-0.63.
