  • Page 8 Section 3 Safety, Installation, Operations & Service Manual Rev. 06/15 DOPSM2080X012 stop random contamination resulting from the installation of the regulator. An auxiliary upstream filter is recommended for use in all but the cleanest media. Gaseous media should be free of excessive moisture to prevent icing of the regulator at high flow rates. A regulator is not intended to be used as a shutoff device.
  • Page 9 Safety, Installation, Operations & Service Manual Section 3 DOPSM2080X012 Rev. 06/15 Care must be used to not damage valve. Several TESCOM regulators are supplied with internal filters. They will be located either in the inlet port or in the main valve area of the regulator. In each case, they should be removed and replaced before reassembly.

    Section 3 Safety, Installation, Operations & Service Manual Rev. 06/15 DOPSM2080X012 Step 4. Turn screw CCW until media flow stops, plus 1/2 turn. Replace hole plug. Reinstalling wire mesh inlet filter: Insert filter into primary inlet port. It then must be expanded to fit correctly.
  • Page 11 Safety, Installation, Operations & Service Manual Section 3 DOPSM2080X012 Rev. 06/15 A regulator is not intended to be used as a shutoff device. When the regulator is not in use, the inlet supply should be turned off. As a safety precaution, a pressure relief device should be installed downstream of the regulator.
