Welcome to the forum. I haven't owned a Cyclone but if your tanks dumps are split to two locations then there is usually one set of tank lever pulls just past the rear wheels on the off door side and another set located in the UDC ( Universal docking center ) where you hook up the water and cable tv. I hope this helps, maybe someone else will chime in here with better info.
It might be helpful if you could post which model Cyclone you have.
Have a great day and congrats on the new to you Cyclone.
