FlowCon FIT-G DN15-32 (1/2”-1 1/4”) 11/2024 Installation and Operation Instruction The FlowCon Energy FIT System is avail- able in an insert-based solution under the name FIT-G . The FlowCon FIT-G is used with: Fitting and Re-fitting the Actuator The suitable actuator is FlowCon FN.0.2, which is an electrical modulating actuator. • FlowCon AB DN15-32 (1/2”-1 1/4”) Figure 1 BMS Insert Setting and Installation Prior to installing the FlowCon Green insert (sup- plied from factory in setting 5.0 due to calibra- tion), the system should be properly flushed. Blank valve covers are available to be installed during flushing. It is recommended to grease the O-rings locat- ed around the insert and headnut with silicone grease before installing the insert in the valve housing. Do not connect power to the actuator unless the actuator is already fitted on the valve and NEVER install the actuator in closed position – this may damage the valve. Actu- ator is supplied in open position to ensure easy commissioning of the system. Mount the actuator on the valve and finger tighten the connection union. Do not use ad- ditional tools. In case the actuator will have to be removed, it is recommended to electrically open the actuator by activating DIP switch #6 for easier removal. Hereafter disconnect power and finger loosen the connection union. Again, no need for additional tools. Please make sure that the actuator is electrically opened, before re-fitting it on the valve. It is essential that the actuator runs linear control mode, 2-10V DC. The desired flow rate is set by adjusting the in- sert (turn counter-clockwise to setting 1.0 and then clockwise up) with a special adjustment key . Range is between 1.0 and 5.0 ⚠ Do not overturn. Scale setting is located on top of the insert, where the large white digits, numbered 1 to 5, indicate full turns and red dig- its, numbered 0 to 9, indicate 1/10 of full turn. Flow setting may be done either before or after the insert is installed in the valve housing. Once flow is set and insert is fitted in the valve hous- ing, the actuator may be applied.
