Notes:

1.Data based on 0.0001 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.Rated in accordance with ARI Standard 550/590-98.

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

8.Use the following equation to calculate COP values at other than ARI conditions, COP = EER x .2928.
