Maytronics Dolphin caddy sub adaptor for ProX2 transformer — BALY, DB4 O'Clair, Facil'O, Ozeo, Zyke - 9980038

Maytronics Dolphin caddy sub adaptor for ProX2 transformer — BALY, DB4 O’Clair, Facil’O, Ozeo, Zyke

This is the genuine Maytronics sub adaptor (ref. 9980038) that bridges the Dolphin caddy trolley to the newer ProX2-style power supply unit. Without it, the transformer sits loose or cannot seat correctly on the caddy frame, leaving your power supply unsupported during storage and transport. It is listed as a sub-assembly part for the Dolphin Supreme M5 platform.

What this caddy sub adaptor does in the Dolphin

The adaptor is a mechanical interface bracket that locks the ProX2 transformer securely onto the caddy body. It replaces the original caddy sub mount when the power supply has been updated or when the original adaptor is cracked, broken, or missing. Without a correctly fitting adaptor, the transformer is not held stable and risks impact damage every time the caddy is moved poolside.

Which Dolphin models it fits

This part is confirmed for use with the Dolphin BALY, DB4 O’Clair, Facil’O, Ozeo, and Zyke models equipped with the ProX2 transformer, as specified in the French source parts list. It is listed under the Dolphin Supreme M5 parent product family. Cross-reference your robot’s model number and transformer type before ordering — if your unit uses a different power supply generation, this adaptor will not engage correctly.

Signs it needs replacing

Check this part if the transformer rocks or shifts when placed on the caddy, if you hear the PSU rattling against the caddy frame during movement, or if you can see visible cracks or deformation on the existing bracket. A broken adaptor does not affect the electrical performance of the robot in the water, but it leaves the transformer unprotected on land.

How to install it

Fit is tool-free or requires only basic hand tools depending on caddy generation. Remove the old adaptor by releasing the retaining clips or screws that hold it to the caddy frame, slide the new sub adaptor into position, and press until the locating tabs click home. Seat the ProX2 transformer onto the adaptor and confirm it is held firmly before use. The whole swap takes under five minutes.
