I am new, aplogies, I now have a JEM Ruby tub, with a HQ2000E pump system. It was already in the garden when house purchased. 
I have the manual for the pump. However I need some more information. 
Does anyone know how I empty it? There is nothing in the manual on this, only the heating settings and so forth. 
ANY help at all would be greatly appreciated. 
Regards
Ronan
