CONTROL BOX 8. Run the cable down the back of the machine. Make sure to run the wire under

SECTION

the bar and bracket in the back so it's not hanging loose.

9. Route the cable between the wash tank and rinse booster, underneath the machine.

10. Once the cable is in the wash tank heater area, route the cable over the highlimit switch.
11. In the control box, attach the red wire from the 6-conductor cable to open tab on the L2 side of the wash motor contactor (R3).
See page 15 for a layout of control box components.
12. Locate and remove the two white wires in the single terminal on the water level controller (WL) at the #1 position. Cut the terminals off of the two white wires.

WARNING
WARNING! To prevent burns, make sure the machine has been off long enough for the water to cool before draining the
booster tank!

NOTICE
If Steps 25 and 26 are done rapidly, minimal water will drain from the booster tank.
25. Get the brass plug from the kit and have it ready. Use a 7/16" wrench on the fitting behind the thermostat. After the fitting is loosened, pull out on the thermostat until the probe is removed from the wash tank.

26. Quickly insert the brass plug into the hole where the thermostat was. Tighten the plug with a 5/8" wrench.

RINSE BOOSTER 27. Find the thermostat on the far-right of the booster tank. Disconnect the yellow/

SECTION

black wire and the white wires from the thermostat.

28. Using a 5/16" nut driver, remove the two nuts securing the thermostat bracket. Be careful with the thin tubing coiled behind the thermostat as you remove the bracket and thermostat from the studs. Also remove the P-clamp that is securing the thin tubing.

29. Remove the probe in the thermowell located in the center of the heater elements by using a box cutter to slice around the edges of the silicone and then pulling the existing probe out. Remove any accessible silicone.

30. Insert the rinse probe into the thermowell from Step 29. If the probe will not fit due to remaining silicone, very carefully use a 1/4" drill bit to remove any silicone within the hole.
Thermistor probe from the kit is used in this step.

Terminal from the kit is used in this step.

32. On the yellow/black wire disconnected in Step 27, cut-off the female terminal and then strip and crimp a male terminal from the kit onto the end of the wire.
33. On the white wire disconnected in Step 27, cut-off the blue female terminal. Remove and discard the white jumper that went to the thermostat from Step 23. Strip and crimp a male terminal to the remaining white wire.

Terminal from the kit is used in this step.

34. Connect the yellow/black wire to the black/white wire from the rinse probe. Connect the white wire to the black wire from the rinse probe. Use a zip-tie to gather the wires.

Zip-tie from the kit is used in this step.

Use cover and hardware removed in Step 2.

35. Verify that the probe is still fully inserted into the thermowell. Re-attach the rinse heater cover with a 3/8" wrench.

WASH TANK 36. Disconnect the white/red wire from the wash thermostat as well as from the

SECTION

high-limit switch. Remove the wire completely and discard.
