Table 26: Water Source Unit DIP Switch Settings.
• After the DIP switch is changed, the reset switch must be pressed to reflect the setting.
• Before operating the water source unit, check the water flow rate and the PCB voltage signal.
• Minimum flow rate range is 50%; Reference flow rate: 4.4-ton - 15.9 gpm.) When the Variable Water Flow Control kit is also installed, set
the flow switch minimum flow rate to 40% of the nominal flow rate instead of 50%. If the flow rate is lower, it will damage the water source
unit.
