4Check the following. ↓ Check the checkbox.
□ All places with flow rate valve opening 1000 through 100 are 2 L or above?
If 2 L/min or below, air may not be bled out. Perform an air bleeding operation and water flow rate adjustment operation again.
□ When there are multiple units, the values of the same pump output opening and the same valve opening are not greater or less than those for other units by 10% and 2 L/min or more.
(In multiple-unit system, perform a water flow rate adjustment operation at the same time.)
□ All the values (item codes d01 through d09) are not “0” when the pump output opening is 16%. (Not whole air is bled out.)
(Note 1) Change SW2-9 and SW2-3 as a stopgap procedure as shown in the table below, and then turn the power on.
