Caution The surge voltage created when the power supply is cut off could apply to the de-energized load equipment through the output circuit. In cases where the energized load equipment has a larger capacity (power consumption) and is connected to the same power supply as the product, the surge voltage could malfunction and/or damage the internal circuit element of the product and the internal device of the output equipment. To avoid this situation, place a diode which can suppress the surge voltage between the COM lines of the load equipment and output equipment. Caution 1) Remove the stopper plate from the adapter plate assembly by using a flat blade screwdriver on the concave of the stopper plate. 2) Take off the pilot valve in horizontal direction. Removal 1) Mount the pilot valve on the adapter plate assembly. 2) Insert the stopper plate into the adapter plate so that the stopper plate will not protrude from the end of the adapter plate.

Insufficient insertion of the tube could cause the air leakage and/or disconnection of the tube. 3) When inserting the tube into the barb fitting, move the tube in parallel to the axis of the barb fitting to avoid any excessive side load to the fitting. 4) Pay attention not to apply any excessive side load to the barb fitting when removing it from the tube. When using a tube cutter or something similar, be careful not to damage or crack the fitting. 5) Do not apply any excessive load such as tensile, compressive or bending force to the tube once connected.
