PRINCIPLE OF OPERATION NORMAL OPERATION: During normal operation the bypass is closed (both handles are positioned parallel with water flow), and water will flow through the strainer, into the FCU and return through the PICV valve. During this operation the PICV will balance the flow from closed valve to design flow depend- ing on actual requirements and corresponding actuator position. BYPASS OPERATION: Option 1. During bypass operation the FCU is isolated from the system. The FCU may, after draining, easily be serviced while the main system is run- ning unaffectedly. It will also be in bypass operation that the main system is flushed without compromising FCU components. Option 2. In addition, complete isolation of the FCU is possible providing closed bypass and isolated flow- and return-side.
