Redring California Shower - quest for information

[rubble2]

Hi,

Daughter has just moved into a flat whilst at University and has a Redring California electric shower fitted. She is struggling a bit with operating it properly as there are no user instructions at the flat.

I have googled for information but no luck so far (nothing for this model on the Redring website).

Just wondered if anyone could point me towards a user manual anywhere on line please?
