Abstract: A control panel, which might be enclosed within an openable housing, can be movably supported on a pivotable support structure. The support structure which incorporates one or more pivot points facilitates movement of the control panel from a normal operational position to a displaced maintenance/service position the control panel can be moved both arcuately and linearly on the support element.

Abstract: A fluid pressure control system which is usable to control pressure in a fluid distribution system includes a variable speed drive coupled to a pump. A hydropneumatic tank is coupled to the distribution system. In normal operation, the variable speed drive actuates the pump so as to maintain pressure in the system. Under low flow conditions, a control unit, using the variable speed drive energizes the pump so as to pump fluid into and pressurize the hydropneumatic tank. The control unit then shuts off the pump. Pressure is maintained in the system, until a predetermined, lower, set point is reached as a result of pressure in the hydropneumatic tank.
