This float switch is rated to directly control motors of up to ½ Horsepower (or 13
Amps) at 120 or 220 Volts AC for non-continuous pump operations, and up to 13
Amps DC for motor loads. Please feel free to contact us for other applications. For
higher horsepower motors, a contactor or relay will be required. This float switch is
made for EMPTYING OPERATIONS. If your application is for FILLING, this product will
not work for you. Contact us and we will help you find a suitable product.
The molded piggyback plug is unique to grounded 120 Volt applications. Your pump
needs a ground and should be plugged into a GFCI receptacle. Your pump will plug
directly into the Piggyback Float Switch as shown in Figure 1. The float switch will turn
the pump on and off automatically.
It is important that the float is installed properly into the
tank. The wire ties in the package will serve to tether the
float switch to the discharge pipe of the pump or another
anchor point in the sump or tank. In the down position the
float should be able to hang freely, and should not rest of
the floor of the sump.
There should be minimum tether length of 2 inches from the
start of the plastic ribbing on the float (see Figure 3). The
float must be able to move unobstructed. If the float is able to get caught on other cables or obstructions in the
tank, it may result in the pump not activating, or running to failure. Be sure to test your installation using a bucket
or a hose to ensure that the float switch is activating and deactivating the pump at the desired level.

READ ALL INSTRUCTIONS BEFORE INSTALLING - ALL APPLICATIONS
NOTICE TO INSTALLER: Instructions must remain with installation.
WARNING: Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers of proper capacity. A separate branch circuit is
recommended, sized according to the National Electrical Code for the current shown on the pump name plate.
WARNING: FOR YOUR PROTECTION ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase pumps are
supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock.
WARNING: DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong
grounded receptacle. If the installation does not have such a receptacle, it must be changed to the proper type, wired and grounded in
accordance with the National Electrical Code and all applicable local codes and ordinances, and should have GFCI Protection.
