The American "ANSI Z21.22" standard is used as the basis for design and verification.
1. How to utilize:
Pressurized solar water heaters, gas heaters, electric heaters, fuel water heaters, heat pump water heaters, sensitive function heaters, and other types of heaters, air and supply hot systems of reduce pressure devices can all be equipped with pressure relief valves, which can automatically lower the temperature and reduce pressure.
2. Installation instructions:

The valve can be positioned either vertically or horizontally, but not inverted, to avoid impurity buildup interfering with regular operations.
The drain valve leak must be grounded, and the atmosphere must be able to be seen draining.
To prevent material and personnel damage, the drain should be kept clear of antifreeze leaks.

3. Regular upkeep:

Users must raise the handle of the relief valve at least once every six months after installing a water heater to make sure that obstructions in the relief valve's waterway have been cleared.
Please ensure that the hot water from the relief valve discharges to the correct location by inspecting the elimination pipeline that joins it before working handles. Failure to do so could result in physical harm.
The relief valve is deemed faulty if the handle is raised without any water escaping. The water heater should then be turned off right away, and the valve should be checked.
