ISO Standard 13256-1 (Water-to-Air and Brine-to-Air Heat Pumps) includes watt allowance for water pumping.

Cooling capacity based on 80.6F DB, 66.2F WB entering air temperature. Heating capacity based on 68F DB entering air temperature.

1See Cross-Reference Chart (Page 2) for approved Bard/ADP Coil part numbers. Charge must be adjusted when using a Fossil Fuel A-Coil. See Installation Manual.

A coil spacer with a minimum height of 6" must be used on all Oil Furnaces to protect the coil drain pan and ensure even airflow across the coil. GTLS-SK2-1 Line Set Stub Kit is required for installation to make connections to the GTC Compressor Section.
