- The capacity rating of this valve must equal or exceed that of the equipment to which it is installed.
- Do not use this valve on a coal or wood fired boiler having an uncontrolled heat input.
- Do not use the test lever as a lifting device during installation.
- Insure that all connections, including the valve inlet, are clean and free of any foreign material.
- Use pipe compound sparingly or tape on external threads only.
- Do not use a pipe wrench! Use proper type and size wrench on wrench pads only.
- This valve must be mounted in a vertical upright position directly to a clean tapped opening in the top of the pressure vessel. Under no circumstances should there be a flow restriction or valve of any type between the safety valve and pressure vessel.
- See ASME Boiler and Pressure Vessel Code and local jurisdiction for additional installation and operating instructions.
- Caution - During operation, this valve may discharge large amounts of hot, high pressure steam or water. To reduce the potential for bodily injury and property damage, a discharge line must be installed that:
- _
- is connected from the valve outlet to a safe point of discharge with no intervening valve;
- allows complete drainage of the valve and discharge line;
- is independently supported and securely anchored to avoid applied stress on the valve;
- is as short and straight as possible;
- terminates freely to atmosphere where any discharge will be clearly visible and is at no risk of freezing;
- teminates with a plain end that is not threaded;
- is, over it’s entire length, of a pipe size equal

- If adding water to a boiler, do not allow water to flow through safety valve as sediment or debris may be deposited on seating surfaces.
- To achieve topmost performance and maximum service life, it is necessary to maintain a proper pressure margin between the set pressure of the safety valve and the operating pressure of the equipment. The minimum recommended operating pressure margin for

- CAUTION! Before testing, make certain discharge pipe is properly connected to valve outlet and arranged to contain and safely dispose of discharge (see Installation Instructions).
- CAUTION! High sound levels may be experienced during lever test. Wear proper safety equipment and exercise extreme care.
- Test at or near maximum operating pressure by holding the test lever fully open for at least five seconds to flush the valve seat free of sediment and debris. Then release lever and permit valve to snap shut. If lift lever does not actuate, or there is
