Little Giant - 599 - Piggyback Mechanical Float Switches

The float switch is a direct-acting, in-line control system for automatically controlling smaller lift pumps and sump pumps in water and sewage system. The float switch consists of one float, one large mounting strap, and two small adjustable mounting clamps.

This pump switch is not designed to be directly wired to relays or motor contractors (the relay or motor contractor may experience chattering). A double float pump switch will operate more efficiently in these installations.

Applications:
  • Sumps
  • Holding Tanks
  • Conversion of non-automatic pumps
  • Replacement for diaphragm or probe type controls

Stop! Required before ordering:

Unless specified above, all pumps are for water use only and are not to be used for any other purpose.

If you are selecting a pump that is designed for pumping products other than water, please check the chemical resistance chart to determine if your pump is fit for your purpose, application and that the pump and seals are compatible for your use.
Warranty is subject to the proper selection of material and seals of the product you are pumping.

WARNING: Turn off power source before installing or adjusting this device. Failure to turn off power could result in serious or fatal electrical shock.

  1. Attach switch cord using the cable tie provided to any convenient rigid surface about 2" below the desired turn-on level. Do not tighten cable tie until turn-on and turn-off levels are established.
  2. Figure "A" Shows an example of turn-on and turn-off levels. Increasing cord length between float and tie point increases on-off differential. Decreasing cord length between float and tie-off decreases on-off differential. Do not tether switch less than 3.5" from pipe.
  3. Tighten cable securely after turn-on and turn-off levels are established
  4. Testing: without water in sump, plug pump cord into switch in-line plug. Plug switch into outlet. Lift float and watch for pump to operate. Do not run pump dry for more than 5 seconds.
  5. Do not leave excess pump or switch cords inside sump as they may tangle float.

NOTE: To prevent pump damage, do not set switch turn-off level below 2" above the base of the pump.

WARNING - 230V INSTALLATIONS: In a 230V pump installation, one side of the line going to the pump is always "hot". This condition exists regardless of whether the float switch is "on" or "off". To avoid hazards when installing or servicing, install a double-pole disconnect switch near pump installation.
