Controller Box
The controller box, located at the upper right side of the TO-Clean, houses the
electrical components, including the Watlow heater controller and the touch
screen controller. Operation of these components is described in the Operation
section of this manual.
There are five 1/8” bulkheads located on the back of the controller box, shown in
Figure 8. If not already connected, attached the tubing show in Figure 6 “Valve
Actuation Air” and “Nitrogen Charge Gas” to the bulkheads labeled “Vacuum
Valve” and “To Tee Fitting”, respectively and connect tubing from the humidifier
shown in Figure 5 to the bulkhead labeled “UHP Nitrogen”.
You will need to connect actuator gas to the bulkhead labeled “Air or Nitrogen -
60 PSIG Max” and the bulkhead labeled “Purge Vent” to a proper vent location.

Troubleshooting note:
Note: If actuator gas is not attached to the bulkhead labeled “Air or Nitrogen – 60 PSI Max” at a minimum
pressure of 55 psig, the vacuum valve will not actuate.
