INSTALLATION
Wet Supply Rotary Switch
1) Drill a 2” diameter hole through the
hopper bottom.
If a flat bottom bin is being
used for a wet storage tank the
Wet Supply Rotary Switch
would be mounted 45 degrees
up the sidewall from the center
of the bin. Example: If the wet
storage bin is 18’ in diameter
then the Wet Supply Rotary
Switch would be mounted 9’
up the sidewall.
2) If the bin is 2.66” corrugation the hole
should be centered on an outside hill.
3) If the bin is 4.00” corrugation the hole
should be centered on an outside
valley.
4) Use the mounting plate as a pattern
and drill four 3/8” holes through the
sidewall at the swich location so the
place can be bolted to the bin.
5) Add foam weather strip around the top
and side of the mounting plate.
6) Caulk the underside of the mounting
plate, on all sides of the 2” hole, and
where the plate meets the bin.
7) Bolt the mounting plate to the
sidewall.
8) Attach the flex coupling to the rotary
switch power pack using a roll pin.
9) Attach the 1-vane paddle to the flex
coupling as shown in figure 6.
10) Apply teflon tape or pipe sealant (not
included) to the rotary switch power
pak threads and thread the rotary
switch power pack into the mounting
plate coupling.
11) Make sure that the conduit hole is
facing down or is horizontal.
