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.
Start-up Checklist and Log
