In order to ensure that the drinking fountain products meet the needs of customers, the installer should ensure that the inlet water quality, inlet pressure, inlet flow, and water temperature of the drinking fountain meet the requirements in the product performance parameter table. If the quality of the influent water is not municipal tap water, you need to add a pre-filtering device in front of the drinking fountain. If the inlet water pressure is too high (more than 3 kg), you need to install a pressure reducing valve in front of the drinking fountain.

        If the inlet water pressure is too small (less than 1 kg), you need to install a booster pump in front of the drinking fountain. When the direct water dispenser needs to be installed in front of a heating device such as a water boiler, it should be ensured that the installation position of the direct water dispenser is lower than that of the water boiler to prevent the steam in the water boiler from entering the water dispenser and damaging the filter element of the direct water dispenser.

        All wading fittings such as pipelines, joints, faucets, etc. on the direct drinking fountains should comply with national sanitary standards. Please do not install it outdoors in northern areas to prevent freezing and cracking of the ultra-filter element, and at the same time prevent direct sunlight. Do not use too much force when tightening the threaded joint during installation to prevent the joint thread from slipping.　　

        Attention to the joint installation of multi-way valve products: 　　

        1. Appropriate amount of raw material tape (also known as water tape) should be wrapped around the outer teeth to avoid water leakage or cracking.　　

        2. When installing the O-ring seal, check whether the seal ring is damaged, twisted, etc.　　

        3. Do not use too much force when tightening the outer teeth straight through, otherwise it may cause thread slippage.
