applications.
Normally Closed - Contacts are closed while hanging down and will open on a rising liquid level. Typically used for fill tank
applications.
Installation
1. Determine desired cable tether length (Fig. 1).
2. Mount the float cable attachment at desired location (Fig. 2) and adjust
the tether length to achieve the correct pumping range. Test the
system by filling/emptying tank and cycling the system to achieve
actual desired pumping range (figure 1 used only as a guide).
3. The float cable attachment should be tightened to prevent slipping and
maintain accurate pumping range.
4. Electrical outlet must NOT be located in pump chamber. Electrical
outlet voltage, piggyback plug voltage, and pump voltage must match.
Piggyback models: insert Big Switch™ piggyback plug into outlet, then
plug the pump power cable into the piggyback plug of the Big Switch™.
Check the system by allowing to cycle to ensure proper operation.
