Hi Charlie Do you have a copy of the instruction manual for the Sharp el-512? Is there any way you could copy this for me. Thanks Greg ... have used this
katie10543- Thank you! I was able to download Berkey_4030-1.jpg and Berkey_4030-2.jpg, the latter shows everything I needed. I'm looking forward to testing
Mike, I have a Berkey 4030 which seems almost identical to your Keystone. I've posted pictures of the wiring here: ftp://ftp.bestweb.net/public_html/repairs/
