DANGER: Operation of the unit with improper relief valve setting can result in severe personal injury or machine damage. Ensure properly set valves are installed and maintained.

To test the pressure relief valve: Raise the system operating pressure to its normal level. Pull the stem ring to open valve and let it vent for a few seconds. Release the stem ring to close the valve.
