Water-to-Water System Design Guide
Part II: Load Side Design / System Design & Selection
CAUTION:
Maximum leaving water temperature of the 50YEW series
equipment is 145°F [63°C]. For domestic hot water tank
temperatures or heating buffer tank temperatures above 130°F
[54°C], pump and pipe sizing is critical to insure that the fl ow
rate through the heat pump is suffi cient to maintain leaving water
temperatures below the maximum temperature, and to provide
water fl ow rates within the ranges shown in the performance
section of this manual.
