Possible consequences include but are not limited to: • High velocity fluid (gas or liquid) discharge • Parts ejected at high speed • Contact with fluids that may be hot, cold, toxic or otherwise injurious • Explosion or burning of the fluid • Lines/hoses whipping dangerously • Damage or destruction to other components or equipment in the system TESCOM™ Safety, Installation, Operations & Service Manual... - Page 5 • 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.

Page 6: Intended Use
Inspect the regulator, valve, and accessories for physical damage and contamination. Do not connect the regulator, valve, or accessory if you detect oil, grease, or damaged parts. If the regulator, valve, or accessory is damaged, contact your local TESCOM representative to have the regulator cleaned or repaired. -

The user is responsible for assuring all safety and warning requirements of the application are met through his/her own analysis and testing. • TESCOM may suggest material for use with specific media upon request. TESCOM does NOT guarantee materials to be compatible with specific media -- This is the responsibility of the user! • Component function, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system user. - Page 8 Assembly/Installation Drawings & Bills Of Material drawings and parts lists for your product may be obtained by contacting TESCOM. Tescom will provide these by email, fax or mail. Your local Tescom representative can provide additional assistance. Be sure to have your complete model number ready.

Final adjustments should be made in the direction of increasing pressure to obtain the most accurate set point. TESCOM regulators will operate with any liquid or gaseous media compatible with the wetted materials. Some series/modifications come with an internal filter designed to stop random contamination resulting from the installation of the regulator. - Page 10 Please reference the Bill of Material and Assembly Drawing for the correct location of replacement parts and correct torque specifications: 1. Inspect all parts and replace those worn or damaged with TESCOM replacement parts. 2. All parts should be cleaned to the cleanliness level required for safe operation with the media and system they will be used in. All parts in the flow stream must be free of...
- Page 11 3.2.2 Pressure Activation Methods TESCOM uses four basic types of activation methods. The activation method provides the means by which the operator can set the force that determines the outlet pressure of a regulator. Control Knob: Delivery pressure is increased by turning the control knob. The control knob applies a load through a spring to the piston.
- Page 12 Final adjustments should be made in the direction of increasing pressure to obtain the most accurate set point. TESCOM regulators will operate with any liquid or gaseous media compatible with the wetted materials. Some series/modifications come with an internal filter that only are designed to stop random contamination resulting from the installation of the regulator.
- Page 13 The last item to be placed in the body of most all of TESCOM regulators is the piston sensor. Place all O-rings and back-up rings that are external to the piston sensor in the body before placing the sensor in place.
- Page 14 500 psig. Pressure Activation Methods 3.3.2 TESCOM uses three basic types of activation methods. The activation method provides the means by which the operator can set the force that determines the back pressure of a regulator. Control Knob: Back pressure is increased by turning the control knob. The control knob applies a load through a spring to the diaphragm.
- Page 15 TESCOM regulators will operate with any liquid or gaseous media compatible with the wetted materials. Some series/modifications come with an internal filter designed to 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...

- Page 19 The valve is closed by turning the hand knob clockwise and opened by turning the hand knob counterclockwise. The hand knob rotation changes the position of the valve stem in relation to the seat. TESCOM valves will operate with any liquid or gaseous media compatible with the wetted materials. A filter is recommended for use in all but the cleanest media. Gaseous media should be free of excessive moisture to prevent icing of the valve at high flow rates.

- Page 21 VL, VM, VT, and VU valves require a minimum pressure of 80 psi for actuation pressure. Please check your drawings for the maximum actuation pressure. TESCOM valves will operate with any liquid or gaseous media compatible with the wetted materials. A filter is recommended for use in all but the cleanest media. Gaseous media should be free of excessive moisture to prevent icing of the valve at high flow rates.
