Work procedure
Remarks
To replace a water circuit part, first close the water
supply source valve and the valve of water pipe
connected to the hydro unit.
The flow switch connection uses an O ring for water
seal. Be careful not to scratch the O ring; otherwise,
water leakage may occur.
After the flow switch replacement repair, open the
water supply source valve and water piping valve to
pass water through the hydro unit, and check that
the flow switch connection has no water leakage.
