When the inlet pressure (P) is shut off and released, the check valve w opens and the pressure in the diaphragm chamber q is released into the inlet side (igure 2). This lowers the pressure in the diaphragm chamber q and the force generated by the pressure regulator spring e lifts the diaphragm.

It is dangerous to replace the pressure gauge or change the mounting angle while it is under pressure.. dvance preparation eep the handle unlocked and completely loosened. The unlocked condition of the handle can be visually confirmed by the Orange line shown near the bottom of the handle. 2. Removing the handle To remove the handle, align the mark on the handle and the mark on the bonnet and then pull the handle. 3. Removing the clip When the mark on the bonnet and the mark on the pressure regulator guide are alligned, the clip can be seen from the side view of the bonnet. The clip can be picked and removed with tweezers.

Please use caution to prevent particles and/or dust from entering the pressure gauge when it is set. Otherwise, they may cause air leakage. 6. etting the clip Insert the clip in the side of the bonnet when the mark on the pressure regulator guide and the mark on the bonnet are aligned. When inserting and setting the clip, use an instrument with a narrow tip, such as tweezers. ote ) The clip is slightly tapered towards its tip to prevent it from being released. et the clip by slightly opening its tip. ote 2) When the clip cannot easily be set, the cause may be as follows: () The pressure regulator screw might have been in a lower position than then the current one. (The pressure regulator screw may reach a lower position if the pressing force of the pressure regulator screw is excessively applied. This occurs because there is a clearance between the pressure regulator nut and pressure spring, when the pressure regulator screw is loosened completely.)
