I just received my heaters today and have a question. The heater is a ebo-jager TS 250 I thought that it was fully submerisable but on the glass tube about a half an inch down it says water level, and above it , it says do not immerse beyond water level. I need to mount these heaters laying on the bottom of my sump. Is it ok to fully immerse them?
Thanks
