This page hosts the official exploded-view diagram and full bill of materials for the Davey ECS Series salt-water chlorinator, covering all four capacity variants: ECS16, ECS24, ECS36, and ECS48. The diagram breaks the unit down into every serviceable component \u2014 from the enclosure and door assembly through to the electrolytic cell, sensors, and internal electronics. Whether you are a pool owner carrying out routine maintenance or a technician diagnosing a fault in the field, every numbered call-out on the diagram corresponds directly to a stocked spare part in the table below. With the part number in hand, you should be able to identify exactly what you need within a few minutes.<\/p>\n
Start by locating the area of the chlorinator you are working on \u2014 for example, the door and front panel, the internal electronics bay, or the cell and plumbing assembly \u2014 then find the corresponding numbered arrow on the diagram. Each number maps to one or more rows in the parts list below; simply match the number to find the SKU you need to order. Be aware that some position numbers appear more than once in the list: this happens when a single numbered location covers model-specific variants, such as position 2 (model label), position 10 (control PCB), position 15 (fuse holder), position 16 (fuse), and position 21 (transformer), all of which differ depending on whether your unit is an ECS16, ECS24, ECS36, or ECS48. Similarly, position 4 carries multiple instrument panel label options and position 6 covers different branding logos, so read each variant description carefully before adding to your basket. Position 34 also lists two distinct fittings \u2014 the European Cell Adaptor and a 50 \u00d7 40 mm Reducing Bush \u2014 so confirm which plumbing configuration your installation uses. When in doubt, cross-reference the description against the label on your existing part or the rating plate on the chlorinator housing.<\/p>\n
Der enclosure and door group<\/strong> (positions 1, 8, 19, 22, 24) covers the moulded door (M1550), door spring (M1560), plastic caps for the top (M1500GRY), top panel (M1551), and the hanging bracket for wall mounting (M1609M) \u2014 these are the parts most likely to show UV degradation or physical damage over time. The instrument panel and labelling group<\/strong> (positions 2, 3, 4, 5, 6, 7) includes the connector cover front (M1554), the instrument panel itself in two configurations \u2014 with clock or light (M1552) and without (M1553) \u2014 plus all associated decals for model identification, operating instructions, and branding logos. The control electronics bay<\/strong> (positions 9, 10, 11, 14, 17, 18, 25) houses the component enclosure plate (M1502), the model-specific PCB Control Complete boards (M111716SP \/ M111724SP \/ M1117A36SP \/ M1117A48SP), the chlorine control knob (M1521), the PCB Pumplite ECS Complete (M1118SP), the rocker light switch (M2011), the E switch (M2004), and the 883 analogue timer with battery back-up (M1812SP). The power and fusing group<\/strong> (positions 12, 13, 15, 16, 20, 23, 31) includes the bottom panel with single powerpoint (M1514M), the power point itself (401954), model-matched fuse holders and fuses, the 12\/22\/32 V light transformer (M1667), stainless pan-head screws (M2826), and cable glands (M4513SP). The cell and plumbing assembly<\/strong> (positions 26 through 37) is where the actual electrolysis takes place: the cell head assembly (M1224H5SP) and cell body (M1249) are the core components, supported by a titanium sensor bolt set (M1103), the cell cord ESC assembly (M2679), a brass cell plug (14530SP), a brass E-Series sensor connector (M2896), and a set of O-rings and EPDM tubing to keep all joints sealed.<\/p>\nChoosing between variants and pack sizes<\/h3>\n
