AstralPool - Bottom Panel for Heat Pump PM40 MD3 - 66069R0292

AstralPool – Bottom Panel for Heat Pump PM40 MD3

This is the genuine AstralPool replacement bottom panel for the PM40 MD3 pool heat pump (model reference WH000420). It forms the structural base of the unit’s outer casing, protecting internal components and maintaining the integrity of the enclosure. Sourced directly from Fluidra, it matches the original factory part exactly.

Compatibility

This bottom panel is designed exclusively for the AstralPool Heat Pump PM40 MD3 (parent model WH000420). It occupies position 16 in the official Fluidra exploded-view diagram. Before ordering, always verify your heat pump’s model reference to ensure a correct fit — this part is not interchangeable with other PM40 variants (MD1, MD2, MD4, etc.).

Why Genuine Matters

Genuine AstralPool parts are manufactured to the same tolerances as the original components, ensuring a flush, secure fit with no gaps that could compromise weather resistance or structural stability. Using a non-OEM panel risks poor fitment, potential ingress of water or debris, and may void any remaining warranty on your heat pump.

Installation

Replacement of the bottom panel typically requires partial disassembly of the heat pump casing. We recommend consulting the official PM40 MD3 service manual and having the work carried out by a qualified pool technician or AstralPool-authorised service engineer, particularly as the unit must be fully isolated from power before any panel work begins.
