When installing TapBoost do specific connections/hoses have to be used?

TapBoost has a 15mm compression fitting on the inlet to allow installation directly onto pipework. The outlet has a ½” BSP male thread allowing any suitable connection to be attached. When installed on mains water applications, no detachable hose sets should be used. If a flexible hose is used for connection to a gravity fed system, it should be no longer than 300mm.
