installation:

unpack and remove any packing material found in the lower housing. Install in piping with the arrow pointing in the direction of flow. The switch must be installed vertically on horizontal pipe runs. To ensure a steady working flow, make certain to keep the paddle flow switch a safe distance from sources of turbulence such as elbows, valves, pumps, etc. The recommended minimum distance upstream and downstream of the flow switch is about 5 times the pipe’s diameter.

maintenance:

inspect and clean wetted parts at regular intervals. The cover should be in place at all times to protect the internal components from dirt, dust, and weather. Disconnect the device from the supply circuit before opening to prevent ignition of hazardous atmosphere.
the model fs-2 paddle flow switch is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before shipping.
