Heat Exchanger Replacement (con't)

15. When replacing the parts, ensure all mating surfaces are clean to

promote good thermal conduction.

16. Place a new narrow aluminum wear plate on the block. Note: All plates

can only be installed one way due to the offset bolt pattern. There are

two sizes of wear plates (narrow and wide)

17. Place the new copper tube on the wear plate. Adjust the runs of the

tube so they do not touch the bolts. The bends in the coil must be facing

DOWNWARDS.

18. Place a new wide aluminum wear plate on the coil.

19. Place the thick aluminum plate onto the wear plate.

20. Place a new wide aluminum wear plate on the thick aluminum plate.

21. Place the second copper tube on the wear plate. Adjust the runs of the

tube so they do not touch the bolts. The bends in the coil must be facing

UPWARDS.

22. Place a new narrow aluminum wear plate on the coil.

23. Place the 1/4" aluminum plate on the wear plate.

24. Add the upper steel plate while checking that the wires are not pinched

or shorted. Thread the five new nuts and washers on finger tight. Check

the alignment of the layers. Tighten the center nut down snug with a

½" socket. Repeat with the other four nuts. Move to the center nut and

pull tighter by a quarter turn. This will give 5-7lbs of torque. Repeat this

on the remaining four nuts.

25. Attach the tubes by screwing in the 7/16" brass nut at the pumps.

Tighten securely.

26. Reinstall the top insulation. Power up the G3000 and allow it to heat

up fully. Run fog through the fog machine until it reaches its lowest

output. Turn off the fog machine and disconnect from the power source.

Retighten bolts if necessary.

27. Reconnect the grounding wire to the case and slide the lid into place and

fasten the machine screws. Plug the machine in and allow it to heat up

completely. Now you're ready to fog.
