| Coolant pump alternative? |

Still need the transformer if it is wired Star and the star point isn't accessible as the O/P stated by implication. |

Has anyone tried using an aquarium tank pump for coolant ? |

Top left U2/W1 Top right Z2 Bottom left Z1/V1 Bottom right U1 I'm not familiar with UVZ, must be chinesium. Terminal box as connected, before disconnecting prior to removal from where I bought it: Motor terminal box : Lifted the terminal box, the star point must be buried in the windings: I'm a sparkie by trade, but that terminology and the way it looks when sketched out as windings makes no sense to me. |

U,V,W are the norms for 3 ph wiring... Imagine a triangle, the corners being marked as U,V and W. One winding would be U1-U2, second would be V1-V2, etc... So for Delta, the connections would be U1 to W2, U2 to V1, V2 to W1... Star connected, the 2's would be connected and phases applied to the 1's |
