KCO Lto HSUP q w e y r t i u o Mounting and Adjustment Warning 1. Releasing the inlet pressure does not mean that all residual pressure is released (the outlet pressure cannot be released). When releasing residual pressure, use a regulator with a backflow function. Selection Be sure to read before handling. Refer to front matter 43 for Safety Instructions and pages 365 to 369 for F.R.L. Precautions. Specific Product Precautions Orange mark 1. Set the regulator while verifying the displayed values of the inlet and outlet pressure gauges. Turning the regulator handle excessively can cause damage to the internal parts. 2. Do not use tools on the pressure regulator handle as this may cause damage. It must be operated manually. 1. Be sure to unlock the handle before adjusting the pressure and lock it after setting the pressure. Failure to follow this procedure can cause damage to the handle and the outlet pressure may fluctuate. . Pull the pressure regulator handle to unlock. (You can visually verify this with the “orange mark” that appears in the gap.) . Push the pressure regulator handle to lock. When the handle is not easily locked, turn it left and right a little and then push it (when the handle is locked, the “orange mark”, i.e., the gap will disappear). 2. When using the regulator between a solenoid valve and an actuator, check the pressure gauge periodically.
