A pressure-relief valve has been installed to prevent damage to the pretreatment system due to excessive
feed water pressure. This pressure-regulating valve has been factory-set. The pressure reading in the
manometer for the pretreatment circuit must remain under 6-bar. Different water supplies are operated at
different pressures, which may make it necessary to readjust the pressure.
为了防止进水的压力太高，在总进水的管路上安装了一个调压阀以防止对于处理部分的损害，该调压阀在工厂
内已经设定好，预处理部分管内水的压力应该设定在
6bar
以下，可以通过压力表进行读数。不同的进水压力
将会导致不同的运行压力，因此有必要对进水压力进行调整。
If the input pressure is too high, the internal pressure switch will turn off RO production (see Chapter 6 –
Warnings). In this case, pull the knob out of the pressure-relief valve and turn it counterclockwise (to
decrease the pressure). Press the knob in once the pressure has been set.
如果进水压力太高，内部的压力开关将会使
RO
产水停止（参见

报警），在这种情况下，拔出调压阀
的旋钮，并逆时针旋转（减小压力），一旦设定好了压力，再按下调压阀的旋钮。
