* Units are rated with 25 ft. (7.6 m) of lineset. See Product Data sheet for performance data when using different size and length linesets.

Notes:

1. Do not apply capillary tube or the fixed orifice indoor coils to these units.

2For Tubing Set lengths between 80 and 200 ft. (24.38 and 60.96 m) horizontal or 20 ft. (6.10 m) vertical differential (250 ft./76.2 m Total Equivalent Length), refer to the Residential Piping and Long Line Guideline for Air Conditioners and Heat Pumps using Puron® Refrigerant.
