1. Capacities are based on temperatures shown in heading, source is left group, return air is right group.

2. Stated Btu/h is the ISO 13256-1 formula adjusted, actual HP supply energy delivered is 2% greater.

3. Temp rise is based on sensible only.

4. All ratings based upon operation at lower voltage of dual voltage rated models.

5. Ground Loop Heat Pump ratings based on 15% antifreeze solution.
