Safety Precautions
1 . Inspect the regulators, valves, accessories and assembly before each use .
2 . Never connect regulators, valves, accessories and assembly to a supply source having a
pressure greater than the maximum rated pressure of the regulator, valve or accessory .
3 . Refer to product label (model specific) for maximum inlet pressures. If this rated pressure
cannot be found, contact your local TESCOM representative for the rated pressure prior
to installation and use . Verify the designed pressure rating of all equipment (e .g ., supply
lines, fittings, connections, filters, valves, gauges, etc.) in your system. All must be
capable of handling the supply and operating pressure .
4 . Clearly establish flow direction of the fluid before installation of regulators, valves
and accessories . It is the responsibility of the user to install the equipment in the
correct direction .
5 . Remove pressure from the system before tightening fittings, gauges or components.
6 . Never turn regulator or valve body . Instead hold regulator or valve body and turn
fitting nut.
7 . If a regulator or valve leaks or malfunctions, take it out of service immediately .
8 . Do not modify equipment or add attachments not approved by the manufacturer .
9 . Apply pressure to the system gradually, avoiding a sudden surge of fluid or pressure
shock to the equipment in the system .
10 . Regulators are not shut-off devices . Install a pressure relief device downstream of the
regulator to protect the process equipment from overpressure conditions . Shut off the
supply pressure when the regulator is not in use .
11 . Periodic inspection and scheduled maintenance of your equipment is required for
continued safe operation .
12 . The frequency of servicing is the responsibility of the user based on the application .
Positive seal/tied diaphragm regulators require the downstream pressure vented before
turning the hand knob counterclockwise to reduce the outlet pressure . Damage may
occur to the regulator if this procedure is not followed .
13 . Never allow problems or lack of maintenance to go unreported .
14 . Read and follow precautions on compressed gas cylinder labels .
15 . It is important that you analyze all aspects of your application and review all available
information concerning the product or system . Obtain, read and understand the Material
Safety Data Sheet (MSDS) for each fluid used in your system.
16 . Never use materials for regulators, valves or accessories that are not compatible with the
fluids being used.
17 . Users must test components for material compatibility with the system operating
conditions prior to use in the system .
18 . Vent fluids to a safe environment and in an area away from employees. Be sure
that venting and disposal methods are in accordance with Federal, State and Local
Section 2: Safety, Installation and
Operations Precautions
