B&C Technologies IM Series Industrial Ironer - Manual (Page 37)

5. Connect a 3/8” copper tube or other suitable tubing to the top of Valve D (bleed valve). The
tube should be long enough to reach a clean 5 gallon bucket containing 1 gallon of oil.
6. Make certain that valves A, C and D are fully open. Valve B should be fully closed.
7. Open Valve E and begin pumping fluid into the system. Continue until a steady stream of
fluid with little or no air comes out of the bleed tube into the 5 gallon bucket.
8. Close Valve D and continue pumping until the expansion tank is filled to 1/4 of its volume.
9. Close valve E and valve D. Open valves A, B, C (A and C should already be open). Make
sure the expansion tank cap is in place.
10. The system should now be nearly full of oil, however there will still be some air bubbles in
the boiler tubes and other locations. The system must now be purged of air. Before pro-
ceeding make certain that the master heat switch on the left control panel of the ironer is
in the off position and the pump switch is in the ”manual” position. The machine should
also be completely assembled, powered, and commissioned before proceeding. During the
remainder of this procedure you should pour fluid accumulated in the 5 gallon bucket in the
expansion tank when the bucket gets 1/2 to 3/4 full. You should also add thermal fluid to
the expansion tank to maintain a level of 1/4.
11. Proceed by turning the ironer on - the pump will start automatically. Leave the machine on
for about 30 sec or until the pump cavitates. Then press the off button to stop the pump.
12. Open valve D, making sure the end of the tube is under the oil level in the bucket to prevent
splashing, and let it run just until no more air or foam comes out.
13. Repeat from step 11 until no air bleeds out during the purge cycles and the pump no longer
cavitates.
14. Set the mode switch on the burner to ”manual” so the burner lights but does not go to high
fire. High fire should not be used during initial degassing.
15. Set the main temperature control setpoint to 150 o F (65 o C). Turn on the machine and set the
heat system control switch to ”on”.
16. While the machine is running, periodically open (about every 30 sec) Valve D for a few sec-
onds and release any accumulated air bubbles. If the pump cavitates, stop the machine and
open valve D for a few seconds to release any air bubbles. Close valve D.
17. Repeat step 16 until no air is released and the pump no longer cavitates.
18. Set the main temperature control setpoint to 210 o F (100 o C).
19. Repeat step 16 until no air is released and the pump no longer cavitates.
20. On commissioning, the protective wax coating will be soft enough to remove using mops,
old towels, or other methods. Remove as much wax as possible before unwrapping and
lowering the rolls. Ensure that all plastic covering and tape is removed prior to dropping the
rolls.
