Connection diagram for prevention of pump idling, alarm and water supply control

When the water supply level drops to the center point of F4, the pump stops and an alarm is sounded. However, the pump starts again when the level reaches to the center point of F3 and the normal automatic operation for the water supply is started.

Installation and connection

  1. Fasten the upper and lower part of the Float tightly to a connection ring conforming to the range of control.
  2. Fasten the main body of the switch to a mounting hole with screw bolt in order that it doesn’t move.
  3. Seperate the cover from the upper cover by unfastening 6 bolts.
  4. Draw out that lead wire inserted in with rubber packing through a hole of the upper cover.
  5. Connect to the terminal A-C, when the lead wire is used for water supply and to B-C for drainage.
  6. Insert a rubber packing after fastening the bolt and covering the upper lid.
  7. Be sure to wind the input packing with insulating tape.
  8. Use magnetic switch adequate for the pump.
