Precaution for cleaning and how to clean

 WARNING
(１) Completely discharge the pressure inside of the product and piping before disassembly and
inspection. Disassembly and inspection must be conducted by an experienced professional.
※Residual pressure, if any, may blow out the fluid, causing bodily injury or bringing pollution to
equipment and facilities.
(２) Never touch the product with bare hands when hot fluid is used.
※Hot fluid may cause burns.

CAUTION
（１）Clean the strainer at regular intervals, once or twice per year.
※Too many scales decrease flow rate and thus performance.
（２）When removing the strainer cap, place a suitable receiver under it. See Fig.6.
（３）When cleaning the strainer, do not remove it from the strainer cap.
※Disassembling the strainer may cause damage to it.
(１ ) Close the slice valve at the inlet and open a faucet located at the end of the piping to completely
relieve the product internal pressure.
(２ ) Turn the strainer cap counterclockwise until it is disengaged.
(３ ) With the strainer cap still attached to the strainer, wash them in water to remove the deposited scales.
(４ ) Attach the set of strainer and strainer cap to the valve body.
(５ ) Open the slice valve at the inlet. Check the strainer cap for leakage. If leaking, replace the O ring
with a new one.
(６ ) Check the flow rate at the faucet located at the end of the system.
