The kit-of-parts design strategy includes product modifications to accommodate the full integration vacuum plumbing inside the demountable partitions.

The horizontal panel frame segment bars and ceiling channels are all ported to accommodate vertical passage of supply and evacuation pipes.

The toilet room sink mounts to the wall panel with a specially designed bracket. The vacuum plumbing accumulator is also mounted to the wall with a bracket and is concealed with a shroud. The plumbing connections are by the vacuum plumbing supplier or general contractor.
