The Davey M1249 is the genuine replacement cell housing for the ProMatic (also known as Ecomatic \/ Chloromatic) ESR, ESC, and MPS series salt water chlorinators. It forms the in-line water chamber through which pool water flows across the electrolytic cell, enabling chlorine production. This part is typically replaced when the original housing develops cracks, leaks, or becomes too clouded to allow visual inspection of the cell electrodes.<\/p>\n
This cell housing fits all ESC, ESCpH, and ESR model Davey ProMatic (Monarch \/ Ecomatic \/ Chloromatic) salt chlorinators, as confirmed in the official Davey spare parts guide. It is also referenced for MPS series units. The housing does not include the electrolytic cell itself, the cell head, or any electrical leads \u2014 these must be transferred from or ordered separately alongside the housing.<\/p>\n
The transparent polycarbonate body is a key functional feature: it lets pool owners and technicians visually inspect the titanium electrodes for calcium scale or dirt build-up without dismantling the unit. A genuine Davey housing ensures the correct thread dimensions for a secure cell head connection, a properly positioned flow-direction arrow, and full compatibility with the integrated gas sensor and flow sensor components of the original system.<\/p>\n
The cell housing is designed to be installed in-line with the pool’s return pipework. It must be oriented so that water enters from the cell-head end, following the directional arrow moulded into the housing, to ensure correct operation of the flow sensor. Professional installation by a qualified pool technician is strongly recommended to ensure watertight unions and correct electrical reconnection.<\/p>","protected":false},"excerpt":{"rendered":"
