It is a good idea to switch off electrostatics for refinement.  The
reason is that the energetic contribution of solvent is usually not 
accounted for in refinement except for well-ordered sites of hydration.  

In the next developmental version of X-PLOR I've switched off 
all electrostatic terms in the refinement tutorial files.  This 
version will become available shortly.
