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.

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.

Section 3 Safety, Installation, Operations & Service Manual Rev. 06/15 DOPSM2080X012 Care must be used to not damage valve. A Special service tool (Part number 6557-3) may be ordered from the factory to aid in the disassembly of the main valve assembly found in TESCOM Regulator Models 26-1000, 26-2000, 44-1100, 50-2000 and 54-2000.
Safety, Installation, Operations & Service Manual Section 3 DOPSM2080X012 Rev. 06/15 Reinstalling wire mesh inlet filter - Insert filter into primary inlet port. It must then be expanded to fit correctly. This can be accomplished by inserting a metal tool the same size as the port and then lightly tapping it with a hammer.

Section 3 Safety, Installation, Operations & Service Manual Rev. 06/15 DOPSM2080X012 3.4.4 Maintenance The following procedures are provided to enable the customer to perform all normal maintenance and repair operations. These operations are more easily performed with the regulator removed from the line. However, in some cases repair may be accomplished without removal of the regulator body as long as the supply has been shut off and the inlet and outlet pressures have been vented.
Safety, Installation, Operations & Service Manual Section 3 DOPSM2080X012 Rev. 06/15 Do not apply any type of grease to threaded internal parts of regulators that come standard with metal to metal diaphragm seals. These models include the following regulator series: 44-2300, 44-2500, 44-2900 and 44-4700. NOTE: Do NOT apply any type of grease to the inlet or outlet connections.
