Two names, one part: distributor files carry it as \"WATER TANK GWS 2-LITERS E.SYBOX\" while DAB's own spare parts list prints position 331 as \"PRESSURE CULINDER FOR E.SYBOX\", DAB's spelling of cylinder. This is the E.sybox integrated expansion vessel. DAB gives it a total capacity of 2 litres and three jobs: \"to make the system elastic so as to protect it against water hammer\", \"to ensure a water reserve which, in the case of small leaks, maintains the pressure in the system for a longer time and spreads out needless restarts\", and \"when the utility is turned on, ensure the water pressure for the seconds that the system takes to switch on and reach the correct rotation speed.\"\u003c\/p\u003e\u003cp\u003ePosition 331 on the DAB E.sybox spare parts list, inside the system. Its air preload is set through the valve reached from the technical compartment (DAB Fig. 3, item 1). DAB is direct about when the whole vessel has to go: the diaphragm \"is typically the component subject to wear for items of this type. However, in the case of breakage, the entire expansion vessel must be replaced and exclusively by authorised personnel.\"\u003c\/p\u003e\u003ch3\u003eFits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDAB E.sybox.

Position 331 carries the same part number, SP00000146, on both lists, so this part is not revision-gated between N.1 and N.3. Only four positions change part number between those two revisions, and this is not one of them.\u003c\/li\u003e\n\u003cli\u003eDAB prints this caution at the head of both spare parts lists: \"Attention: check the correspondence with the revision of your product.\" To read your own pump: the technical data plate sits inside the technical compartment (DAB instruction manual 60168399, Fig. 3, item 2, reached by removing the inspection door on Face A), or power the pump up and open the VE page in the menu, which DAB section 7.1.11 \"VE: Version display\" describes as the \"Hardware and software version with which the appliance is equipped.\"\u003c\/li\u003e\n\u003cli\u003eDAB gives you a test before you spend the money. Its troubleshooting table lists \"Expansion vessel empty (insufficient air pressure) or has broken diaphragm\" against the symptom that water pressure is not immediate when a tap is opened, and the remedy reads: \"Check the air pressure through the valve in the technical compartment. If water comes out when checking, the vessel is broken: assistance service. Otherwise restore the air pressure.\" Water at the valve means you need this part. No water at the valve means you may only need to reset the preload.\u003c\/li\u003e\n\u003cli\u003eDAB warns the preload check itself must be done carefully: \"on small volumes the loss of even a limited quantity of air can cause an appreciable drop in pressure\", and any check or reset \"must be performed with the delivery system not under pressure\".\u003c\/li\u003e\n\u003cli\u003eDAB states this replacement is to be done \"exclusively by authorised personnel\".\u003c\/li\u003e\n\u003cli\u003eFitment note for North American buyers: every DAB E.sybox spare parts list we can source is drawn against the AU market build, printed on the list as \"E.SYBOX V220-240 50\/60Hz AUS PLUG\". We have no DAB spare parts list for a North American NPT build, so confirm this part number against your own technical data plate, or with DAB, before you order. We are not going to pretend an AU list is a US list.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Valley Milan","offers":[{"title":"Default Title","offer_id":52946659672375,"sku":"DABSP00000146","price":182.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/dab-water-tank-gws-2l-esybox-sp00000146-1.jpg?v=1788499509","url":"https:\/\/www.blacklabelsupply.io\/products\/dab-water-tank-gws-2l-esybox-sp00000146","provider":"BLACK LABEL","version":"1.0","type":"link"}
