MANUAL MANIFOLD OPERATING INSTRUCTIONS

1. open the cylinder valve D on the required in use bank of the manifold Check the cylinder connection for leaks using a weak solution of soapy water Slowly and fully open the valve B on the in use bank of the manifold Adjust the regulator control knob E until the outlet gauges reads approximately 50 100 kPa Wait until the pressure into the pipeline stabilizes ie cannot hear gas flowing through the regulator Slowly continue to adjust the regulator knob until the desired pipeline pressure is reached If fitted the pipeline isolation valve can also be used to control the rate at which the pipeline is pressurized Note attempting to rapidly pressurize the pipeline system may damage the supply regulator TO CHANGE OVER TO THE RESERVE BANK i Slowly and fully open the cylinder valve D1 on the reserve bank Check the cylinder connection for leaks using a weak solution of soapy water Note If the pipeline system empties before changing over follow the to open the working in use bank procedure m Close the valve B on the empty working bank of the change over block and immediately but slowly open the valve B1 on the reserve bank Close the valve D on the empty cylinder Remove the empty cylinder and replace it with a full one Ensure that new cylinder valve outlet is clean Momentarily open then close the cylinder valve to blow out any fore2. MANUAL MANIFOLD OPERATING INSTRUCTIONS NO SMOKING OR NAKED FLAMES USE NO OIL OR GREASES IMPORTANT Ensure that the regulator connected to the manifold has an inlet pressure rating equal to or higher than the maximum fill pressure of the cylinders being used Do not use oils or greases on the manifold or associated components Open all valves SLOWLY and FULLY to ensure the pressure increases gradually Do not remove the plastic caps in cylinder valve outlets until ready for use TO PUT THE MANIFOLD INTO OPERATION 1 Ensure that all outlet points in the pipeline system are closed 2 Check that valves B and B1 on the change over block are closed 3 Ensure that each cylinder valve outlet is clean Momentarily open and then close each cylinder valve to blow out any foreign matter and ensure that each cylinder is full Close each cylinder valve lightly to make slow opening after connection to the manifold easier Connect cylinder leads coils to the cylinder valve Ensure that the ends of the leads coils are not contaminated with any foreign matter or that they are not damaged NOTE On commissioning a new gas pipeline system it must be purged through with the working gas to ensure that no atmospheric air is present in the pipeline TO OPEN THE WORKING IN USE BANK 1 Ensure that the regulator control knob E is fully backed off ie turned fully anti clockwise 2 Slowly and fully
