(Refer to Fig.1) 2) Rotating H-direction (Clockwise) increases pressure, while L- direction (Counter-Clockwise) for decrease. (Refer to Fig.2) 3) Knob cannot be rotated when they are pushed to be locked. (Refer to Fig.2) NOTE: Use in setting pressure range. -
Page 26: Piping
5 ．INSTALLATION 5-1. Piping 1) Ensure air flow coincides with the directional arrows on cover plate. 2) Flush air into the pipe to blow out foreign substances and chips before piping. 3) Refrain applying sealant or sealing tape approx. Two pitches of thread off the tip of pipe to avoid residual substances from falling into piping system. - Page 27 5-2. Installation ■ When the mounting direction "No sign: Vertical mounting" is selected. 1) Installation is made with mounting hole of T type bracket. Refer to outline drawing. 2) Install so that drain discharge port faces downward. 3) Install as close to the pneumatic equipment as possible. 4) Allow a minimum of 20 mm above the top and 30 mm below the unit for maintenance purpose.
