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 specic) 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, ttings, connections, lters, valves, gauges, etc.) in your system. All must be
capable of handling the supply and operating pressure.
4. Clearly establish ow direction of the uid 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 ttings, gauges or components.
6. Never turn regulator or valve body. Instead hold regulator or valve body and turn
tting 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 uid 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 uid used in your system.
16. Never use materials for regulators, valves or accessories that are not compatible with the
uids being used.
17. Users must test components for material compatibility with the system operating
conditions prior to use in the system.
18. Vent uids 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
October 2016
5

requirements. Locate and construct vent lines to prevent condensation or gas
accumulation. Make sure the vent outlet is not obstructed by rain, snow, ice, vegetation,
insects, birds, etc. Do not interconnect vent lines; use separate lines if more than one
vent is needed.
19. Do not locate regulators, valves or accessories controlling ammable uids near open
ames or any other source of ignition.
20. Some uids when burning do not exhibit a visible ame. Use extreme caution when
inspecting and/or servicing systems using ammable uids to avoid death or serious injury
to employees. Provide a device to warn employees of these dangerous conditions.
21. Many gases can cause suffocation. Make certain the area is well ventilated. Provide a
device to warn employees of lack of Oxygen.
22. Never use oil or grease on these regulators, valves or accessories. Oil and grease are easily
ignited and may combine violently with some uids under pressure.
23. Have emergency equipment in the area if toxic or ammable uids are used.
24. Upstream lters are recommended for use with all uids.
25. Do not bleed system by loosening ttings unless specied by Instruction Manual.
26. Prevent icing of the equipment by removing excess moisture from the gas.
27. Always use proper thread lubricants and sealants on tapered pipe threads.

2.2 Installation
Do not open packaging until ready for installation or in a clean environment. Product is
cleaned in accordance with CGA 4.1 and ASTM G93, Verification Type 1, Tests 1 and 2. With
periodic verification of cleaning process to MIL-STD-1330D.
Make sure that the components and materials used in the fluid handling system are
compatible with the fluid and have the proper pressure rating. Failure to do so can result in
death, serious injury and/or property damage.
Inspect the regulator, valve, accessories and assembly for physical damage and contamination.
Do not connect the regulator, valve, accessory or assembly if you detect oil, grease or damaged
parts. If the regulator, valve, accessory or assembly is damaged, contact your local TESCOM
representative to have the regulator cleaned or repaired.
2.3 Repair Service
If a regulator or valve leaks or malfunctions, take it out of service immediately. You must have
instructions before doing any maintenance. Do not make any repairs you do not understand.
Have qualied personnel to make the repairs. Return any equipment in need of service to your

DOPSM2097X012
equipment supplier for evaluation and prompt service. Equipment is restored to the original
factory performance specications, if repairable. There are at fee repair charges for each
standard model. The original equipment warranty applies after a complete overhaul.
Proper Component Selection
1. Consider the total system design when selecting a component for use in a system.
2. The user is responsible for assuring all safety and warning requirements of the application
are met through his/her own analysis and testing.
3. TESCOM may suggest material for use with specic media upon request. Suggestions
are based on technical compatibility resources through associations and manufacturers.
TESCOM does NOT guarantee materials to be compatible with specic media -- THIS IS
THE RESPONSIBILITY OF THE USER!
4. Due to the varying composition, viscosity, corrosiveness and density of chemical uids,
the uid media and full system must be considered by the user when selecting a product.
This is required to ensure regulator performance, user safety, ow capability and system
level performance.
5. Component function, adequate ratings, proper installation, operation and maintenance
are the responsibilities of the system user.

Section 6: Installation and Start-Up Procedures
Failure to follow these instructions or to properly install and maintain this equipment could
result in an explosion, fire and/or chemical contamination causing property damage and
personal injury or death.
TESCOM regulators must be installed, operated and maintained in accordance with federal, state
and local codes, rules and regulations.
If the regulator vents gas or a leak develops in the system, service to the unit may be required.
Failure to correct trouble could result in a hazardous condition.
Installation, operation and maintenance procedures performed by unqualied personnel may
result in improper adjustment and unsafe operation. Either condition may result in equipment
damage or personal injury. Call a qualied personnel when installing, operating, and maintaining
the 56-21XX and 56-22XX Series regulator.
Personal injury, equipment damage or leakage due to escaping fluid may result if needle
valves are used to isolate the pressure reducing regulator. It is strongly recommended that
block valves be used to properly isolate the regulator from system.
Personal injury, equipment damage or leakage due to escaping accumulated uid or bursting of
pressure-containing parts may result if this regulator is:
• Over-pressured
• Used with incompatible process uid
• Installed where service conditions could exceed the limits given in the specications section
and on the appropriate nameplate
• Where conditions exceed any ratings of adjacent piping or piping connections. To avoid such
injury or damage, provide pressure-relieving or pressure-limiting devices to prevent service
conditions from exceeding those limits
Conrm with gauges that there is zero pressure in the system prior to installation:
Note: Refer to the Installation Diagram for additional information.
1. Re-tighten ttings on assembly as they may have loosened during shipping.
2. Rotate valve hand knob (B) clockwise until it stops turning. This will close the valve
which will prevent pressurized ow through the regulator/valve assembly.
3. Close the inlet (C) and outlet (A) block and bleed valves surrounding the regulator and
pressurize the supply side or inlet side of the system.
4. Install the regulator/valve assembly with the inlet port of regulator (E) connected to
the supply or inlet piping of the system and connect the outlet port to the downstream
piping in the system using plumbing supplier specied torque values.
5. Slowly open the inlet block valve (C) to apply pressure to the inlet of the 56-2XXX Series
assembly regulator (E).

6. Verify the regulator’s inlet pressure (F).
7. Slowly open the Valve hand knob (B) to apply pressure to the regulator/valve assembly.
8. For 56-21XX Series only, slowly turn the bleed plug (D) approximately 1/4 turn
counterclockwise to vent any entrapped air. Tightly close plug after all air is evacuated.
9. Slowly open the outlet block valve (A) to allow pressurized ow through the system.
10. Verify the regulator/valve assembly’s outlet pressure (G) to determine if there is any
leakage. If there is any leakage, remove the 56-2XXX Series assembly for inspection and
repair. If no leakage occurs move on to Step 11.
11. Check the Bleed Plug (D) for any sign of liquid leakage. If leakage occurs remove
56 Series regulator for inspection and repair. If no leakage occurs move on to step 12.
12. Verify and record ow rate and pressure over time.
13. Adjust valve (B) by turning the hand knob to the desired orice size until desired ow
rate is achieved.
