Series FS6
Flow Switch
(specified models only)
OPERATION
This control is an independently mounted water flow
sensing device that makes or breaks an electrical
circuit when flow stops or starts.
• Before using product, read and understand instructions.
• Save these instructions for future reference.
• All work must be performed by qualified personnel trained in the proper application,
installation, and maintenance of plumbing, steam and electrical equipment and/or systems in
accordance with all applicable codes and ordinances.
• To prevent electrical shock, turn off the electrical power before making electrical
connections.
• To prevent an electrical fire or equipment damage, electrical wiring insulation must have a
rating of 167˚F (75˚C) if the liquid's temperature exceeds 180˚F (82˚C).
• To prevent electrocution, when the electrical power is connected to the flow switch, do not
touch the terminals.
• Make sure flow switch electrical cover is secured before turning on electric power.
Failure to follow this warning could cause property damage, personal injury or death.
