UP
Intermittent fill maintains a “wet” coil. This
operation is active when the unit is in wet lay-up.
Wet lay-up is used when the unit will be shut down
for only a short period. The INTERMITTENT
FILL WATER PUMP ON message appears on the
left of the screen (Fig. 4-10) while the unit is in wet
lay-up.
The wet lay-up process is initiated by pressing
the AUTO SHUT DOWN icon on the main menu
screen (Fig. 4-1 on page 4-1).
Verify the bypass valve is open. Verify the
header valve, dry shut down valve, and
maintenance drain valve are tightly closed. Make
sure feedwater quality is maintained throughout the
wet lay-up period. Verify there are no leaks
anywhere in the plumbing during wet lay-up.

The unit will develop rust or other forms of
oxidation inside the coil tubing if dry shut down
is executed improperly.
A dry shut down should be performed
by Clayton service personnel or other
personnel who are thoroughly trained in
Clayton steam generators.
A dry shut down maintains a “dry” coil when
a unit will be shut down for a prolonged period—
usually exceeding 14 days.
The dry shut down process is initiated by
pressing the DRY SHUT DOWN icon on the main
menu screen (Fig. 4-1 on page 4-1).
The “dry shutdown in progress” screen (Fig.
4-11) will display and step through the shut down
process.
The operator must be present
throughout this process to perform
required operations as indicated on the
screen (Fig. 4-12) and verify and
acknowledge the control valves during
the dry shut down.
