CAUTION:
Some area plumbing codes require drains to flow
into an open gap with an opening twice the diameter
of the pipe. Check with your local plumbing codes for
the type of drain connection required.
CAUTION:
Do not reduce the size of lines as specified in
installation drawings. All lines are sized to facilitate
necessary flows, pressures, etc.
Chemical Supplies
The LT-40 control box is provided with detergent,
rinse aid and sanitizer chemical feeder pumps. Each
pump is equipped with a supply tube which has a
stiffener tube attached at the end. Place the chemical
container such as detergent, rinse aid, and sanitizer in
a place where the stiffener tube can appropriate them.
Insert each individual supply tube into each chemical
container.
Red Supply Tubing = Detergent
Blue Supply Tubing = Rinse Aid
White Supply Tubing = Sanitizer
Pump Priming Instructions
When all the chemical tubes are connected correctly,
follow the below procedure to prime the pumps:
1. Close the doors and turn the MAIN POWER switch
to the ON position.
2. Press and hold the FILL button to fill the tank with
water.
3. The detergent, rinse aid, and sanitizer PRIME
switches are located on the control box beneath
each pump. To prime each pump, press and hold
the PRIME switch until the chemical has entered
the sump. This can be verified by opening the
doors slightly.
4. Once complete, close the doors and run one empty
cycle.
5. At the end of the cycle, press and hold the DRAIN
button to empty the tank.
6. Turn the MAIN POWER switch to the OFF position.
Open the doors. The machine is now ready to use.

PART 2 INSTALLATION INSTRUCTIONS
Setting Chemical Volumes
Your chemical supplier will be able to provide you
with the appropriate chemicals to meet your needs.
The supplier will also be able to tell you the correct
volume of each chemical required per cycle.
The chemical pumps have a flow rate of 1.95 mL per
rotation with 22 rpm. You can set the fill volume of
the sanitizer, detergent and rinse aid by adjusting the
right side of CAMs 5,6, and 7 respectively.
The chlorine concentration in the wash tank must be
at least 50 ppm. To verify this, follow these steps:
1. Close the doors and turn the MAIN POWER
switch to the ON position.
2. Press and hold the FILL button to fill the tank with
water.
3. Open the doors and wait for 10 seconds. Close the
doors to start a cycle.
4. At the end of the cycle turn the MAIN POWER
switch to the OFF position and open the doors.
5. Using a chlorine titration kit, measure the
concentration of chlorine in the tank.
6. If necessary, adjust the right side of CAM 5 to
ensure the concentration is at least 50 ppm.
Setting Water Fill Volume
Before washing ware ensure that CAM 4 is set for the
correct fill volume:
1. Close the doors and turn the MAIN POWER
switch to the ON position.
2. Press and hold the FILL button to fill the tank with
water.
3. Open the doors and wait for 10 seconds. Close the
doors to start a cycle.
4. At the end of the cycle turn the MAIN POWER
switch to the OFF position and open the doors.
5. Verify that the water level is between the two lines
on the drain stopper pipe. If not adjust the right
side of CAM 4 and run another cycle.
