Abstract
A control unit is formed of a housing containing a filter with an inlet and outlet in line above the filter, the latter forming a channel with the housing; a pressure reducer is positioned between the inlet and the outlet above the filter. A rotary valve positioned between the filter and the pressure reducer reverses the flow in the unit. A plug-valve is located in the housing to provide drainage and the plug-valve is connected to the rotary valve so that on reversal of flow, the plug-valve opens to drain the unit.
