Note: The actual ow rate may differ from the setting depending on variation of the ow
rate sensor in the ow control valve.
e.g. Total ow rate setting [standard 1.06 gal/min (4.0 L/min)] --> actual ow rate [1.19
gal/min (4.5 L/min)]
If the difference is too large, use the adjustment mode (AdJ.) to adjust the total ow
rate (A3).
e.g. Total ow rate setting [0.92 gal/min (3.5 L/min)] --> actual ow rate [1.06 gal/min
(4.0 L/min)]
