The following is standard procedure for replacing the rotor:
• Open door at the front of the cabinet.
• Remove the bolt/nut in front of the gear motor, to allow loosening of the drive belt (see the
picture in the “Replacing gear motor” section above).
• Remove the drive belt from the pulley.
• Remove the rotor gaskets.
• Remove the flex-tube connections to the regeneration fan. The regeneration fan can now
be moved slightly, so the rotor shaft can be removed.
• Remove the top and bottom bolts for the rotor shaft, and slide the rotor shaft out through
the bottom.
• If needed, remove the bolts for the distance rods between the top and bottom rotor section
plates. The bottom rotor section plate will now be free.
• Carefully slide out the rotor (including the top Teflon® and silicone discs, and the bottom
Teflon® disc).
• You can now install a new rotor. Slide it back into the machine and put the 10mm solid
Teflon® disc underneath the rotor. Put the 1mm Teflon® disc and the 12mm sponge
silicone seal on top of the rotor. Make sure the 1mm Teflon® disc is below the 12mm
sponge silicone seal (see illustration above).
• Reinstall the rotor shaft. If the bolts to the distance rods were loosened, these can be
tightened now.
• Reinstall the flexible tube connections to the regeneration fan. Make sure the metal clamps
are tightened, and the flexible tubes are properly connected. (Try pulling slightly on the
flexible tubes – they should not move).
• Reinstall the rotor gaskets and tighten the metal clamps holding them. Turn the rotor and
make sure the gaskets fold onto the rotor section plates (top/bottom) all the way around.
• Put the drive belt back on the pulley, and tighten the belt, by choosing a corresponding
hole for the bolt/nut in front of the gear motor (see the picture in the “Replacing gear motor”
section above).
NOTE:
Transfer hinges and the rotor guard bracket to the new rotor.
(see illustration above)
o The rotor guard bracket must be aligned with the rotor guard sensor.
o The hinges must be placed underneath the drive belt so that the belt will grip these
when the rotor is turning.
