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.
