Notes:
1. Data based on 0.00025 fouling factor at sea level.
2. Interpolation between points is permissible.
3. Extrapolation beyond points is not permissible.
4. EER - Energy Efficiency Ratio (Btu/watt-hour). Power inputs
include compressors,condenser fans and control power
5. Ratings based on evaporator drop of 10°F
6. Ratings based on ARI Standard 590-92.
7. Data obtained assuming 400 Volt supply. |
