Float Switches
For unattended operation of the submersible pump two Model SW1WOPA float switches will be required. These float switches have bare wires on one end of the cable for direct connection to either the CB6 or CB200 Control Boxes. The illustration below is an example of using two single float switches in a typical dewatering application.
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.
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.
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.)
