FlowCon FH / FH-BUS / FH.1 Actuators 1B95036 - 06/2023 Installation and Operation Instruction The actuator types FlowCon FH, FH-BUS and FH.1 are electrical, high force actuators. • FH is all-in-one including 24V modulating, 3-point floating and 2-position. • FH-BUS is equal to FH, but includes Modbus and BACnet communication. • FH.1 is 24V modulating and 2-position fail safe version. Fitting and Re-fitting 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 tight- en the connection union. Do not use additional tools. OFF and wait until the LED indicator is blincking green. Again, no need for additional tools. Please make sure that the actuator is electrically opened, before re-fitting it on the valve. Figure 2 Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation. 360º Figure 3 Figure 1 In case the actuator will have to be removed, it is recommended for FH and FH.1 to electrically open the actuator for easier removal. Hereafter disconnect power and finger loosen the connec- tion union. For FH-BUS set DIP switches #1-6 to This paper is a supplement to the FlowCon General Instruction Latest release of any FlowCon material is available on www.flowcon.com Page 1 of 8
