Depressurization valve The watermaker group is constituted of the following components: The Reverse osmosis membranes, inside the silver high-pressure vessel are used to separate the intake high-pressure seawater into two flows: one for the salt-water waste and one for fresh water production.
  • Page 6 Depressurization valve Reset valve Positioner Probe (pressure switch). It is a little steel device, mounted on the aluminum structure. It is connected to the computer throw the cables PS / PS . Its function is to check the cycling of the machine .
  • Page 7 2. Installation 2.1 General criteria It is important to plan carefully the activity prior to start the installation works, evaluating any possible alternative solution. The fundamental choices to make are: Finding of seawater intakes and any necessary fittings. Positioning of main units . Positioning of pumps operation automatic circuit breakers.
  • Page 8 2. Installation 2.3 Water intakes The necessary hydraulic intakes are: • Seawater intake It is ideal a specific sea water intake, size ¾” min. in a central position, well under the water surface even when the vessel is well heeled over. The skin fitting is recommended.

The timer is activated if the START button is pushed for more than 3 seconds only. • BY-PASS It allows to exclude the sensor (signal pressure switch) that detects the correct cycling of the ERS.
  • Page 15 The message must be acknowledged pushing STOP. This messages means that an hydraulic block of the machine occurred, and then the pumps has been switched off as safety procedure. In this case is suggested to perform a reset procedure and investigate on the possible hydraulic origins of the problem.

This means that pressure on both sides of the valve are the same and the unit is effectively stalled and has to be manually restarted. In this case the working pressure goes up suddenly (up to 9 Bar) and the pumps are switched off from the pumps pressure switch.
