Note: The above water volume is the total unit water volume ( Source + Load), divide the above volume by 2 to obtain source or load side volumes individually.

Flow Checks

For the operating temperature drop (heating) and rise

(cooling), refer to Table 7 through Table 12 for the proper

water temperature 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 7 through Table

12 to determine flow.
