ECS Series Chlorinator (ECS16 / ECS24 / ECS36 / ECS48) exploded view & spare parts

Davey ECS Series Chlorinator (ECS16 / ECS24 / ECS36 / ECS48) exploded view & spare parts

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 — 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.

Come utilizzare lo schema numerato per individuare il proprio componente

Start by locating the area of the chlorinator you are working on — for example, the door and front panel, the internal electronics bay, or the cell and plumbing assembly — 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 — the European Cell Adaptor and a 50 × 40 mm Reducing Bush — 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.

Main replaceable assemblies on the Davey ECS Series Chlorinator

Il enclosure and door group (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) — these are the parts most likely to show UV degradation or physical damage over time. The instrument panel and labelling group (positions 2, 3, 4, 5, 6, 7) includes the connector cover front (M1554), the instrument panel itself in two configurations — with clock or light (M1552) and without (M1553) — plus all associated decals for model identification, operating instructions, and branding logos. The control electronics bay (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 (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 (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.

Choosing between variants and pack sizes

The most important variants to get right are the model-specific electrical components: the control PCB (position 10), transformer (position 21), and fuse holder with fuse (positions 15 and 16) are each rated differently across the four models. The ECS16 and ECS24 use a 3 A fuse (M2901) with fuse holder M2953SP, while the ECS36 and ECS48 step up to a 5 A fuse (M2906) with holder M2954 — fitting the wrong-rated fuse will either blow immediately or fail to protect the board. The transformers for ECS16 (M1714) and ECS24 (M1715) are individually specified, while ECS36 and ECS48 share transformer M1788; always confirm your model from the rating label before ordering. Position 34 presents a different kind of choice: the European Cell Adaptor (M1215) and the 50 × 40 mm Reducing Bush PVC (M3626) serve different plumbing configurations, so identify your pipe diameter and fitting style before selecting. For small consumables such as the stainless screw at position 23 (M2826), check whether the diagram notes a quantity per unit so you order an adequate number to complete the job in one go.
