Note: Chart PD-3 includes factory piping and condenser. If adding a water regulating valve, add valve WPD to the
value in Chart PD-3. 10 and 15 ton units use two water regulating valves. Therefore, divide the gpm and WPD by 2 to
determine values through each valve.
Note: Table PD-5 is based on wide open water valve.
