Operating Pressures

Water Pressure Drop

Tables 6 and 7 should be used to define feet of head/pressure drop. Note: To calculate feet of head, when using gauges that read in PSIG, multiply PSI by 2.31.

Note: The EXWA 240 has two circuits.

Flow Checks

For the operating temperature drop (heating) and rise (cooling), refer to Table OP1 and OP2 for the proper water tempera- ture change. Depending on the unit size, entering water temperature and water flow rate, the cooling temperature rise is from 8°F-16°F. Based on the same criteria for heating, the temperature drop is from 2°F-13°F.

Pressure

Using the P/T ports and one 0-60 psi pressure gauge with the P/T port adapter, measure the pressure difference between the water-in and water-out connections. Compare the pressure differential to Table 6 to determine flow.
