When the job is done and it is time to shut the machine down turn the main power
switch to the off position and the unit will automatically go into “Cool Down” mode
shown with indicator light. Doing so removes power from the furnace and allows the
heat transfer fluid to continue to circulate until the furnace cools down to at least
130° F on the temperature/pressure gauge on the face of the furnace. Doing this wil-
lavoid hot shut down on the boiler and allow the hoses to cool down so they are not
hot to the touch but still pliable enough for winding up the hose for storage.
Once the temperature on the temperature / pressure gauge on the face of the fur-
nace has reached at least 140 °F you can turn off the generator or disconnect from
shore power. Close the fuel valve on the fuel tank. Closing the fuel valve on the fuel
tank will help prevent air from getting in to the fuel supply to the burner. If air get in
the fuel supply it may cause the primary controller to go into a lock out condition the
next time the machine is fired. Close the automatic air bleeders. Remember to re
-
open the automatic air bleeders when setting the machine up at the next job. Close
the ball valves on the manifold.
