Installation 1. Install valve on return line of equipment to be balanced or as shown on the plans. 2. For maximum accuracy, the flow measurement/balancing valve should be located in an unrestricted straight pipe run so that no fittings (elbow, valve, tee, etc.) is closer to the flow measurement/balancing valve than 5 pipe diameters upstream and 2 pipe diameter downstream. If a balancing valve is located downstream from a circulation pump, allow a distance of ten (10) diameters between the pump and balanc- ing valves. 3. Series CSM-81-F flow measurement/balancing valves are bidirectional and should be installed to insure ease of hooking up meter and adjusting setting Flow Measurement Instruction 1. With wrench, turn indicator to open position on indicator plate. 2. Connect, vent and prepare the differential gauge. Refer to instructions furnished with the gauge. 3. After initial pressure differential reading is taken, refer to flow rate charts to obtain flow rate based on pressure differential and valve setting. If flow rate is in excess of that specified, turn indicator towards closed position, noting pressure drop and valve setting and determining new flow rates from flow rate chart. The unit or system has now been balanced. 4. Disconnect differential gauge.
