I want to add snubber or supression protection diodes for a solid state relay. Here is the diagram without the diodes:
And this is the SSR I'm going to use:

What kind of diodes I need and where to place them? The load is a speed controller together with a single phase inductive fan-motor and will not draw more than 1A in steady state.

RS state that that unit has an internal snubber but don't give the full Crydom part number so you can check.
Figure 1. Extract from Crydom Series 1 datasheet.
Contact RS and ask them for the full part number.
