Safety, Installation & Operations Precautions
10. Clearly establish flow direction of the fluid before installation of controllers,
regulators, valves and accessories. It is the responsibility of the user to install
the equipment in the correct direction.
11. Remove pressure from the system before tightening fittings, gauges
or components.
12. Never turn controller, regulator or valve body. Instead, hold the controller body
and turn fitting nut.
13. If a controller, regulator or valve leaks or malfunctions, take it out of
service immediately.
14. Do not modify equipment or add attachments not approved by
the manufacturer.
15. Apply pressure to the system gradually, avoiding a sudden surge of fluid or
pressure shock to the equipment in the system.
16. Regulators are not shut-off valves. Install a pressure relief device downstream
of the regulator to protect the process equipment from operating pressure
increases. Shut off the supply pressure when the regulator is not in use.
17. Periodic inspection and scheduled maintenance of your equipment is required
for continued safe operation.
18. The frequency of servicing is the responsibility of the user based on the
application. Never allow problems or lack of maintenance to go unreported.
19. Read and follow precautions on compressed gas cylinder labels.
20. 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.
21. Never use materials for controllers, regulators, valves or accessories that are
not compatible with the fluids being used.
22. Users must test under normal operating conditions to determine suitability of
materials in an application.
23. 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 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.
24. Do not locate controllers, regulators, valves or accessories using flammable
fluids near open flames or any other source of ignition. Use of Hazardous Location
controllers may be necessary to be in accordance with local electric codes.
25. Some fluids, when burning, do not exhibit a visible flame. Use extreme caution
when inspecting and/or servicing systems using flammable fluids to avoid
death or serious injury to employees. Provide a device to warn employees of
these dangerous conditions.
26. Many gases can cause suffocation. Make certain the area is well ventilated.
Provide a device to warn employees of lack of Oxygen.
27. Never use oil or grease on these controllers, regulators, valves or accessories.
Oil and grease are easily ignited and may combine violently with some fluids
under pressure.
28. Have emergency equipment in the area if toxic or flammable fluids are used.
29. Upstream filters are recommended for use with all fluids.
30. Do not bleed system by loosening fittings.
31. Prevent icing of the equipment by removing excess moisture from the gas.
32. Always use proper thread lubricants and sealants on tapered pipe threads.
