Reinstalling the Aluminium Steam Generator
(for both 1st generation and Alex versions)
NOTE: DO NOT use this section when REPLACING or UPGRADING older 1st generation
aluminium steam generators to the newer Alex type. These instructions apply only to RE-
INSTALLING an aluminium steam generator (including Alex) that has been removed.
Instructions for UPGRADING to the Alex steam generator vary depending on the status of the unit
that is being upgraded (i.e., what controller and software revisions it has) and may also change
from time to time. For the most up to date procedures concerning an upgrade, use the matrix in
Figure 2 to find the appropriate kit number and follow the instructions included with the kit.
To reinstall the steam generator, proceed as follows (see Figure 3):
1. Make sure the power switch is OFF, and the unit is unplugged.
2. Place the steam generator in to position.
3. Connect the compression nut (18) holding the steam generator outlet tube (19) to the top
of the steam generator outlet fitting (20) and the compression nut (21) holding the steam
generator outlet tube to the probe bracket inlet fitting (22). Thread the nuts and finger tighten,
then tighten with a wrench. Do not over tighten.
