Installation of Wall Mounted Level Switch
Drill 2" hole through wall at desired location. If bin is 2.66" corrugation, hole should be centered on outside
hill. If bin is 4.00" corrugation, hole should be centered on outside valley.
Position mount plate as desired (from inside), mark and drill 3/8" holes. Caulk coupling abundantly where
it passes through wall. Add foam weather strip around top and sides of plate then bolt to bin wall. Caulk
coupling to wall seam from outside.
Attach flex coupling to power-pak. Add teflon tape or pipe sealant (not provided) to power-pak pipe
threads and thread into coupling. Conduit opening should be horizontal or down. Add 1 vane paddle.
(Paddle may be added to flex coupling before power-pak is threaded into coupling if desired.)
