7. Check to ensure the oat switch still works by turning on both vacuums
with the vacuum tank lid off. Reach inside and lift the oat nger. If vacu-
ums turn off, the oat works. If the vacuums stay on, the oat body may
need replacing, or the oat nger is installed upside down.
Auto-ll Float Switch Replacement
Required:
-Colored tape
-New oat switch, rubber washer, and plastic nut
-Silicone
-Medium/deep depth 13/16” socket and ratchet
-Medium crescent wrench
1. In a clear and open space, lay down a piece of cardboard or scrap
material.
2. Undo rear latches of LTD machine by turning them counter clockwise
3. Open the machine until it is resting on the scrap material previously
placed on the oor, which will help minimize scratching and damage to the
front of the LTD machine.
4. Locate auto-ll oat switch wires coming out of the blue solution tank
and disconnect the two oat switch wires that are plugged into the system.
At this point, use the colored tape to mark the wires that the oat switch
was unplugged from.
5. Close the machine halfway by setting the handle on a 5-gallon bucket
or stand of similar height.
6. Locate the position of the oat switch inside of the solution tank on the
back wall of the tank.
7. Once located, reach in and hold the oat switch lever all the way to one
side by pushing on the opposite side.
8. Using your other hand, or nger, roll the clip off of its tabs by pulling on
the bottom of the opposite tab from which you are pushing. It should not
take a lot of pressure to remove the switch, so be careful not to break it.
9. Place the medium crescent wrench on the back nut of the oat switch
and the 13/16” socket on its inside nut. Loosen the oat by rotating the
ratchet counter clockwise until completely loose. Make sure not to lose
any nuts or rubber washers in case they are needed in the future.
10. On the new oat switch, hold the oat switch lever all the way to one
side by pushing on the opposite side.
11. Using your other hand, or nger, roll the clip off of its tabs by pulling on
the bottom of the opposite tab from which you are pushing. It should not
take a lot of pressure to remove the switch, so be careful not to break it
12. Place the rubber washer over the threads of the new switch and all the
way down to the 13/16” nut side.
13. Place a thin layer of silicone on the rubber washer where it will be
contacting the solution tank wall.
14. Thread oat switch-with actuating nger off-wires back through
vacuum tank hole and thread it in using the 13/16” socket. Make sure the
wires go down into the base of the machine.
15. Using your hand, thread the plastic nut onto the back side of the oat
switch placing the medium crescent wrench on the nut to hold in place
16. Tighten the 13/16” oat until snug. Make sure at side of the oat body
is facing towards the top of the solution tank.
17. Replace oat nger, at side down, onto the male position tabs located
on the oat switch body in the vacuum tank. First, hook one side of the
nger to one tab. Then roll and pull the tab with index nger until other clip
snaps into place.
18. Locate auto-ll oat switch wires coming out of the blue solution tank
into the machine. Re-connect the two-oat switch wires to the previously
marked wires. It will not make a difference which wires you plug into each
port, just make sure both wires are re-connected.
19. Close the machine and re-latch.
20. Check to ensure the oat still works by hooking up the auto-ll feature
like normal. Turn on water. Reach inside and lift the oat nger. If water
stops coming into the tank, the oat works. If the water keeps pouring in,
oat nger may be installed upside down or wires may not be connected
completely.
Pump does not work properly
1. Snap quick disconnects rmly together.
2. Check solution tank; may be empty.
7. Using the Philips head screw driver, remove the two Philips head
screws and pull the blue face box out.
8. Once the blue switch box is removed, the back end of the vacuum oat
switch should be visible.
9. Remove the 7” clear vacuum tank lid located on top of the vacuum tank.
Use a ashlight to locate the position of the oat switch on the front wall
inside of the tank.
10. Once located, reach in and hold the oat switch lever all the way to
one side by pushing on the opposite side.
11. Using your other hand, or nger, roll the clip off of its tabs by pulling on
the bottom of the opposite tab from which you are pushing. It should not
take a lot of pressure to remove the switch, so be careful not to break it.
12. Place the medium crescent wrench on the back nut of the oat switch
and the 13/16” socket on its inside nut. Loosen the oat by rotating the
ratchet counter clockwise until completely loose. Make sure not to lose
any nuts or rubber washers in case they are needed in the future.
13. On the new oat switch, hold the oat switch lever all the way to one
side by pushing on the opposite side.
14. Using your other hand, or nger, roll the clip off of its tabs by pulling on
the bottom of the opposite tab from which you are pushing. It should not
take a lot of pressure to remove the switch, so be careful not to break it
15. Place the rubber washer over the threads of the new switch and all the
way down to the 13/16” nut side.
16. Place a thin layer of silicone on the rubber washer.
17. Thread oat switch-with actuating nger off-wires back through
vacuum tank hole and thread it in using the 13/16” socket. Make sure the
wires go down into the base of the machine.
18. Using your hand, thread the plastic nut onto the backside of the oat
switch placing the medium crescent wrench on the nut to hold in place
19. Tighten the 13/16” oat until snug. Make sure the at side of the body
is facing towards the top of the vacuum tank.
20 . Replace oat nger, at side down, onto the male position tabs
located on the oat switch body in the vacuum tank. First, hook one side
of the nger to one tab. Then roll and pull the tab with index nger until
other clip snaps into place.
21. Replace blue switch box with two Philips screws.
22. Return the black plugs back over the screw holes for a clean and
professional appearance.
23. Open the machine until it is resting on the scrap material previously
placed on the oor.
24. Locate the vacuum tank oat switch wires coming out of the black
vacuum tank and re-connect the two oat switch wires into the previously
marked ones. It will not matter which wire you plug into each port, just
make sure both wires are re-connected.
25. Close the machine and re-latch.
26. Check to ensure the new oat switch works by turning on both vacu-
ums with the vacuum tank lid off. Reach inside and lift the oat nger. If
vacuums turn off, the oat works. If the vacuums stay on or will not turn
on, the oat nger may be installed upside down or wires were not con-
nected completely.
Auto-ll Float Switch Maintenance and Replacement
Cleaning and maintaining oat switches will help extend the life your
machine. Regular cleaning is required for proper functionality. To clean
auto-ll level switch:
1. Open the black lid on the blue solution tank.
2. Use a ashlight to locate the auto-ll tank’s oat switch, which is on the
back wall of the blue tank about 5” from the bottom of the tank.
3. Once located, reach in and hold the oat switch nger all the way to one
side by pushing on the opposite side.
4. Using your other hand, or nger, roll the clip off of its tabs by pulling on
the bottom of the opposite tab from which you are pushing. It should not
take a lot of pressure to remove the switch, so be careful not to break it.
5. Check the oat nger and where it attaches for debris or any other
damage and if dirty, clean. If one of the male tabs where the oat hooks is
damaged, refer to the oat switch replacement section.
6. Once cleaned, replace the oat nger at side down onto the male posi-
tion tabs located on the oat switch neck in the vacuum tank. First, hook
one loop of the nger on one tab then roll and pull the other tab with your
index nger until it snaps back into place.
