the manufacturer recommended that?i washed it out with dawn dish soap to get rid of all the oils from the factory.
to ease your mind.... level looks low in those pix... and if it overflows it appears that it will safely overflow into your sumpno wasnt recommended i just figured dawn broke down oils so i did it and it seemed to work was making foam right off the bat. will set it low when i get home from work hopefully it hasnt done anything major while im here
