the vacuums and cause damage. To maintain these lters:
1. Remove the 7” clear vacuum lid.
2. Reach in and pull out the two black lters located in the top of the
vacuum stacks.
3. Clean the lters under a faucet of any debris and check for damage.
If the lters are not damaged, place them back in the stacks. If lters are
damaged and falling apart, replace them.
Pump-Out Filters
The pump-out lter is located on the inside bottom of the black vacuum
tank. It is recognizable by its cylindrical shape. To maintain lter:
1. Remove the 7” clear vacuum tank lid.
2. Reach in and unthread the cylindrical lter by rotating it counter clock-
wise. A ashlight may be needed to locate the lter.
3. Once the lter is out, slide off foam sleeve that surrounds the wire
screen. Check for debris and damage. Rinse lter of any debris or replace
if damaged.
4. Place lter back into vacuum tank by rotating it clockwise onto the brass
nipple.
Pump Filters
The pump is a half-circle shaped screen located on the inside bottom of
the blue solution tank. To maintain lter:
1. Open black solution tank lid.
2. Reach into solution tank and rotate the dome-shaped lter from its
brass nipple by rotating it counter clockwise.
3. Check lter for any debris or damage to screen. Rinse lter of any
debris or replace if damaged.
4. Place new or cleaned lter back onto brass nipple by rotating it
clockwise.
Auto-Fill Solenoid Filter
The solenoid lter is located inside of the auto-ll solenoid, which is inside
the base of the machine. The lter will be connected to the auto-ll male
QD that extends from the back of the machine. To maintain the lter:
Required Tools:
7/8” Wrench or crescent wrench.
¾” Wrench
1. Open the machine by undoing the rear latches and rocking the top of
the unit forward until it is resting on the ground and the internals of the
base are exposed.
2. Locate the solenoid attached to the rear auto-ll and pump-out plate.
3. Place the 7/8” wrench of crescent wrench on the rear part of the
solenoid closest to the inside of the auto-ll plate to help prevent rotation
during steps 4 & 6.
4. Use the ¾” wrench to loosen the ¾” plug on the front of the solenoid.
5. Remove the solenoid screen and check for any debris or damage to
screen. Rinse the screen of any debris or replace if damaged.
6. Replace the ¾” brass plug and screen then you can continue use as
normal.
Oil Vent Solenoid Filter
The oil vent’s solenoid lter is located on top of the general pump head
inside the base of the machine. It will be connected to the brass tee
coming out of the oil ll hole. To maintain ler:
Required Tools:
7/8” Wrench or crescent wrench.
¾” Wrench
1. Open the machine by undoing the rear latches and rocking the top of
the unit forward until it is resting on the ground and the internals of the
base are exposed.
2. Locate the solenoid attached to the brass tee on top of the pump head.
3. Place the 7/8” wrench of crescent wrench on the rear part of the sole-
noid closet to the inside of the auto-ll plate to help prevent rotation during
steps 4 & 6.
4. Use the ¾” wrench to loosen the ¾” plug on the front of the solenoid.
5. Remove the solenoid screen and check for any debris or damage to
screen. Rinse the screen of any debris or replace if damaged.
6. Replace the ¾” brass plug and screen then you can continue use as
normal.
Trouble Shooting
There is no power.
1. Plug power cord(s) in proper outlet(s).
2. If using two cords, make sure each is plugged into a separate circuit.
3. Check circuit breaker and reset if tripped. There should not be any
additional items in use on the same circuit as the machine and the outlet
must be a 20-amp circuit.
LTD Float Switch Maintenance
Each LTD machine contains two water level oat switches. These oat
switches control specic functions of the machine. The rst oat switch will
control the auto-ll feature while the second oat switch controls power
to the vacuums. These levers prevent water from getting into the vacuum
stacks and spilling out from the solution tank.
Vacuum Tank Float Switch Maintenance & Replacement
Cleaning and maintaining oat switches will help extend the life of your
machine. Regular cleaning is required for proper functionality. To clean the
level switch:
1. Remove the 7” clear vacuum tank lid located on top of the tank.
2. Use a ashlight to locate the oat switch that will be located on the front
wall of the vacuum 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.
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
vacuums turn off, the oat works. If the vacuums stay on, the oat body
may need replacing, or the oat nger is installed upside down.
Vacuum Tank 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
-Long shaft Phillips screw driver
-Flathead screwdriver
Instructions:
1. In a clear and open space, lay down a piece of cardboard or scrap
material.
2. Undo the 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 the vacuum tank’s oat switch wires coming out of the black
vacuum 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.
6. Locate blue switch plate box that holds the switches. Using the at head
screwdriver, remove the two black caps covering the Philips head screws
that hold the switch box.
