Float Switches

For unattended operation of the submersible pump two float swith methods can be used single or dual. The single float switch (Model SW1A) will allow the pump to turn on and off depending on the length of the tether. When using the dual float switch (Model SW2A) method the pump will turn on or off at a pre-determined water level. This water level is set by the length of the tether.

Mounting The Float Switches

1.

Determine the required cord tether length as shown

 

in Figure 5 and Table 3.

2.

Place the cord into the clamp as shown in Figure 8

NOTICE

Single float switch, Model SW1A has a pumping range between 5.5~18 in. (14~46 cm.). Dual float switch has a pumping range between 1~ 48 in (2.54~122 cm.)

 

and Figure 9

3.

Secure the clamp to the discharge hose as shown in

 

Figure 8. DO NOT install cord under hose clamp.

4.

Using a screwdriver, tighten the hose clamp. DO NOT

 

over- tighten. Make sure the float cord is not allowed

 

to touch the excess hose clamp band during operation.
