(4)  Remove bolts holding flowmeter, and replace it. A white back plate (to make the float easy 

to see) is attached. The end of the pin holding down the back plate must be on the bracket 

side.

(5)  Replace piping, and

 fix M6 bolts between brackets. *1

     *1 :  When disassembling and reassembling, mark original positions, and tighten an extra 5-10° when reassembling.  

After tightening, do a liquid leakage test.
