5. Pit versions

The pits come with pipes and valves, depending of the installation 
selected. Some pumps are available with a float switch connected 
directly to the pump and thus require no external or built-in 
controller.

The following installation drawings show pits with a free-standing 
pump, a pump on auto coupling, a pump on wall-mounted auto 
coupling and a pit with two pumps.
