CSB400 Series Regulator Installed with the Vent Pointed Downward and with a Type 289H Relief Valve for High Capacity Relief Type CSB403 Integral True-Monitor™ Operation Type CSB403 combines the operation of a conventional two-regulator wide-open monitor set into one body, see Figure 5.
CSB400 Series In order for the Underpressure Shutoff (UPSO) of any slam shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint.

CSB400 Series Installation Location • The installed regulator should be adequately protected from vehicular traffic and damage from other external sources. • Install the regulator with the vent pointed vertically down, see Figures 7 through 10. If the vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover.
CSB400 Series For Type CSB423 with external control lines, use tubing with an outer diameter of 13 mm / 0.5 inch or larger for both the primary regulator and Integral True-Monitor™. Downstream Control Line Installation with Slam shut Refer to Figure 10.
CSB400 Series The range of allowable pressure settings for the primary regulator is stamped on the nameplate. If the required setting is not within this range, substitute the correct spring (as shown in Table 6). If the spring is changed, re-stamp the nameplate to indicate the new pressure range. A pressure gauge must always be used to monitor downstream pressure while adjustments are being made. For Types CSB400 and CSB420 1. Remove the closing cap (key 60, Figure 16). 2.

Sealant must be selected such that it meets the temperature requirements. 2. The torque range as specified is initial assembly torque. Due to elastomeric compression, the torque values indicated may decrease.
CSB400 Series Maintenance and Inspection ! Note For adjusting setpoints above 100 mbar / 1.5 psig, use a 13 mm / 1/2-inch hex driver, a 13 mm / 1/2-inch socket or a 27 mm / 1-1/16-inch socket to turn the adjusting screw (key 65). WARNING To avoid personal injury or equipment damage, do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure as described in “Shutdown”.
CSB400 Series 6. Reassemble the spring case (key 1) unit in the reverse order of the above steps. Before tightening the cap screws (key 15) or stem (key 44) into the pusher post (key 51), place the loosely-assembled diaphragm assembly (key 55) into position in the lower casing (key 9), being sure that the pusher post (key 51) is hooked on the lever (key 10). Rotate the diaphragm (key 55A) so that the diaphragm and lower casing (key 9) holes are aligned.
