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. Minimum recommended ethylene glycol percentage used for leaving water temperatures below 40°F.
