Determining Pumping Range
in Inches (1 inch - 2.5 cm)
Use only as a guide. Due to weight of
cable, pumping range above horizontal
is not equal to pumping range below
horizontal. Ranges are based on testing in
nonturbulent conditions. Range may vary
due to water temperature and cord shape.
As tether length increases, so does the
variance of the pumping range.

V,WU MODEL INSTALLATION
Model WU are fully automatic. Afloat switch is included and factory
wired in the pump circuit to provide automatic operation once the
float switch is secured properly to the outlet pipe. Use the diagram
above to secure the float switch properly and obtain the proper
tether to customize the on-off cycle to each application.
