Start Capacitor for Pool Pump - 20 µF - Mini Delfino 80, 100, Structural, Hydronaut

This capacitor is part of the corresponding single-phase motor circuit and supports correct starting and running.

Pool technician’s advice

Match the capacitance in µF, rated voltage, dimensions and connections of the original capacitor. Do not select a different capacitance because the name is similar. Have a qualified technician replace it.

What to check before ordering

Difficulty starting or motor humming may relate to the capacitor, but other faults can cause the same symptoms. Have the cause diagnosed before replacement. Increasing capacitance is not a repair for a motor fault.

How to choose the correct version

Use the original capacitor specifications: capacitance in µF, rated voltage, tolerance and terminals or leads. Check the available mounting space and fastening. Motor supply voltage is not the same as the capacitor voltage rating.

When to replace the part

Check it when the motor has starting or running problems. A qualified technician must establish the cause and match capacitance, rated voltage and connections.

Important points when replacing the part

Have a qualified technician replace it. A capacitor can retain an electrical charge after the supply is disconnected. The wiring and motor operation must be checked using the manufacturer’s service procedure.

Version details

Disconnect the pump from the power supply and drain the water before disassembly. Motor repairs, capacitor replacement and mechanical seal installation should be carried out by a qualified technician.

Using the exploded diagram

The listed position refers to the corresponding assembly diagram. The arrow helps locate the part; for some small components it marks only the fitting area. Compare the original part, its code and the specific pump version before ordering. You are ordering the item named in this listing, not the complete assembly in the diagram.
