Pushed down diaphragm will disconnects the disc from the stem. The set pressure level stays by transferring pressure to lower diaphragm, which will result in balancing the adjust spring. In case of higher pressure than set level, the pressure pushes diaphragm and pressure is released through the hole on the spring case. Dimension (YT-200 / 205) Dimension (YT-220 / 225) 6 YT-200 / 205 / 220 / 225 series 3. Installation 3.1 Safety When installing a unit, please ensure to read and follow safety instructions.  Check unit’s specification and ensure to be used as specified.  Ensure the air quality is clean and dry.  Please operate the unit within the specified range of the air pressure level. If exceed, the product can be damaged and may result in result damages and accident.  After the pressure level is adjusted, please make sure that the adjust bolt is completely fastened. 3.2 3.3 YT-200 / 205 / 220 / 225 Installation YT-200 / 205 / 220 / 225 can be installed with or without a bracket depending on the field requirement. Please refer to YT-200 / 205 / 220 / 225 dimensions to make appropriate bracket, if required. Adjustment 1) Before supply main air pressure to the product, please turn the adjusting bolt in counter clockwise, so the ring is not being pushed. 2) Install a pressure gauge on the secondary pressure output port to monitor the pressure level constantly. The pressure gauge indicates the primary pressure that is being output from the product. 3) Block output port and pressure gauge port with ball-valve type or other type of fitting and supply primary pressure to input port. 4) When secondary pressure reaches at the set level, please fasten the adjust bolt. 7 YT-200 / 205 / 220 / 225 series 4. Maintenance 4.1 4.1.1 4.1.2 YT-200 / 205 / 220 / 225 require regular maintenance. Please refer to below repair kit part list. It is suggested to replace all parts at the same time to guarantee the life cycle of the product. Repair kit  Upper diaphragm assembly:  Lower diaphragm: 1 each 1 each Draining condensed water  When draining out condensed water, the main supply pressure to the product must be shut down completely or adjust the pressure level of 1kgf/cm2 or below.  Slowly open drain plug to drain condensed water.  After the draining, please close the drain plug. 4.1.3 Replacing the filter case and parts.  When replacing the filter case or any parts, the main supply pressure to the product must be shut down completely or adjust the pressure level of 1kgf/cm2 or below.  Release the lock nut on the adjust bolt, and rotate the adjust bolt counter-clockwise to lower the setting pressure.  Open drain plug on filter case to drain condensed water and close.  Unscrew the bolts on the filter case in diagonal order.  Replace the filter, o-ring, and stem.  Screw the bolts on the filter case in diagonal order.  Unscrew 6 bolts on the spring case in diagonal order.  Replace the diaphragm assembly.  Screw the bolts on the spring case in diagonal order. Please make sure not to damage the diaphragm when screwing.  After the part replacement, please re-set the air pressure at the desired level. 8 YT-200 / 205 / 220 / 225 series
