FLOAT SWITCHES

Float Switches

For unattended operation of the submersible pump two single fl oat switches (Model SW-1WOPA) will be required. These float switches can be connected directly to a control box (bare wires) and will allow the pump to turn on and off depending on the length of the tether.

Mounting The Float Switches

1.Determine the required cord tether length as shown in Figure 3 and Table 2.

2.Place the cord into the clamp as shown in Figure 6.

3.Secure the clamp to the discharge hose as shown in Figure 6. DO NOT install cord under hose clamp.

4.Using a screwdriver, tighten the hose clamp. DO NOT over- tighten. Make sure the fl oat cord is not allowed to touch the excess hose clamp band during operation.
