Rotary Switch Instructions
Installation of Roof Mounted Level Switches
Drill 2" diameter holes through roof panels at locations shown on Page 3 . Use a mounting plate as a
pattern and drill four (4) 3/8" holes through roof panels at each switch location so the plate can be bolted to
the roof.
Attach flex-coupling to the power-pak. Apply teflon tape or pipe sealant (not included) to power-pak pipe
threads and thread power-pak into mounting plate coupling. Conduit opening in power-pak should be at
right angles to roof rib or face toward eave.
Caulk underside of mounting plate above and both sides of 2" hole. Bolt to roof panel.
Attach shaft extension according to Figure 2 and Figure 3 on Page 2 . Use teflon tape or pipe sealant
(not included) on shaft guard (see Figure 2 and Figure 3 on Page 2 for lengths) and thread to underside
of mount plate coupling. Add 1/4" drilled coupling and paddle. (NOTE: Single vane paddle is used on LOW
level switch.)
