3/4″liquid flow switch, HFS-20 dn20 water flow paddle control switch SPDT contact 6-380V

Specifications: Model: HFS-20 Switch type: SPDT Material: 304 stainless steel body, copper connector, phosphor bronze bellows Connector: 3/4 ” Maximum working pressure: 1.0MPa Liquid temperature: -10-100 ° C Micro switch voltage: 220VAC Microswitch current: 15A Package list: 1 * Water flow switch 3 * Paddle 1 * User Manual Note: 1. Check the flow switch carefully before installation. 2. The flow switch can be installed in a horizontal or vertical pipeline with the liquid flow direction upward, but not in a pipeline with the liquid flow direction downward installing in pipelines with upward liquid flow, the effects of gravity must be taken into account. 3. The HFS flow switch cannot be used with pipes whose liquid temperature is below the freezing point. 4. When fixing the quick close valve downstream, an arrester must be installed. 5. Pay attention to the following when installing the wiring. (1)ying an impact to the switch base plate wrench is absolutely forbidden, leading to deformation and failure of the flow switch. (2) off the power when wiring or debugging. (3) wiring, adjusting screws other than the micro switch terminal and grounding screw is absolutely prohibited, if the wires are carefully connected, the position of the microswitch itself can be easily changed, causing the flow switch to fail. (Four)ng requires the use of special ground screws, and the mounting screws cannot be removed. (Five) flow switch blade cannot contact the inner wall of the pipe or any other throttle in the piperwise, the switch cannot be reset successfully.
