User manual DHI MOLSTIC HI FLOW MOLBLOC MOUNTING SYSTEM

[. . . ] Calibration Solutions for Pressure and FlowTM Instruction Sheet molsticTM hi flow P/N 401663 molblocTM Mounting System DESCRIPTION molstics provide an engineered solution to the practical issues of mounting a molbloc, connecting a gas supply, regulating the pressure and connecting the device to be tested. Highest quality components are integrated into a convenient, compact assembly. molstic, hi flow (P/N 401663) is designed for use with the 1E5 molbloc at flows up to 100 slm. [. . . ] Read the molbloc upstream pressure using the [P&T] function of the molbox (see the molbox Operation and Maintenance Manual). Adjust the molbloc upstream pressure to the desired value by inserting a screwdriver into the regulator stem (4) and rotating the adjustment screw until the desired pressure is set. If desired, once the desired pressure is set, lock the regulator stem by tightening the jam nut on the stem. % Install the MFC/device under test: The downstream connection is 1/2 in. For DUT fittings other than VCR, use the appropriate adaptor (not supplied). If desired, install the DUT platform (2) to assure that the DUT is at the correct height for alignment with the molstic downstream fitting (see DUT PLATFORM INSTALLATION AND OPERATION below). If you have a metering valve option for manual flow control, install it here. VCR molsticTM, hi flow, molblocTM Mounting System Instruction Sheet molbloc INSTALLATION !Loosen the interconnecting nipple clamp (3) so that the nipple can move freely in its rubber grommet. Move the nipple away from the molbloc cradles to allow maximum room for molbloc insertion. # Place the molbloc in the molstic molbloc cradles (be sure flow orientation is correct). $ Connect and tighten the upstream (valve side) molbloc VCR connection using a soft O-ring and following the procedure provided in Document 560009 (Recommendations for molbloc Installation) supplied with the molbloc. % Pull the interconnecting nipple towards the molbloc downstream connection. Connect and tighten the downstream molbloc VCR connection using a soft O-ring and following the procedure provided in Document 560009 (Recommendations for molbloc Installation) supplied with the molbloc. & Tighten the interconnecting nipple clamp (3) until the nipple is secure (5 N/m max). Break the downstream molbloc VCR connector and pull the interconnecting nipple away from the bloc.
