DAB's manual, section 13.3, states that the system has an integrated non-return valve which is necessary for correct operation, and that the presence of solid bodies or sand in the water could cause malfunctioning of the valve and therefore of the system. DAB recommends using fresh water and fitting filters on the input.\u003c\/p\u003e\u003cp\u003eDAB's spare parts sheet lists it as \u003cstrong\u003e(SP) ESYBOXMAX - NRV GROUP\u003c\/strong\u003e at position 121, in the delivery assembly group (position 120) alongside the water tank, the pressure sensor and the Schrader air valve. The drawing shows the valve entering a port on the manifold behind a cap secured by four screws, with position 135 O-ring kit items either side of it. Manual section 13.3 gives the removal sequence: disconnect the electric power supply, drain the system, remove the four screws, remove the cap using the accessory tool (or pliers), remove the valve, then clean it under running water, ensure it is not damaged and replace it if necessary.\u003c\/p\u003e\u003ch3\u003eFits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDAB EsyBox Max.

That manual does not list the 45\/120 M208-240 at all, and the spare parts sheet cited here is for the 45\/120 M208-240. The two documents cover different model sets.\u003c\/li\u003e\n\u003cli\u003eManual section 13.3 describes the integrated non-return valve and its removal for the EsyBox Max without distinguishing between the models the manual covers.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBefore You Order\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eAttention: check the correspondence with the revision of your product.\u003c\/em\u003e That caution is printed across the header of DAB's spare parts sheet.

DAB has not published a parts sheet in the documents used here for the 60\/120 T or 85\/120 T, so the item number for three-phase machines is not confirmed by these sources.\u003c\/li\u003e\n\u003cli\u003eDAB's manual asks you to clean the valve first and replace it only if necessary (section 13.3, step 3d). Two symptoms in DAB's troubleshooting table point at this valve: the pump starting without a utility request, listed against a leak in the system or a faulty non-return valve; and DAB's own cross-reference there sends you to the non-return valve service paragraph.\u003c\/li\u003e\n\u003cli\u003eRemoval needs the DAB accessory tool or pliers, and the system has to be drained first (manual sections 13.1 to 13.3).
