Notes:
1. If the required water temperatures of the heat emiers are not all the same, the Heat Pump Splits outlet water temperature seng should be set at the
highest of the heat emier required water temperatures. If the water outlet design temperature falls between two temperatures listed in the outdoor
units capacity table, calculate the corrected capacity by interpolaon.
2. If the outdoor unit selecon is to be based on total heang load and total cooling load, select Split units which sasfy both total heang and cooling load
requirements.
