AutoFlush Valve with Cord
Installation Instructions.
OPERATION
The optional AutoFlush System feature automatically drains
the MrSteam generator following each use. A time delay
allows the water to cool down (about two hours) before it
drains by gravity for a safe and gentle operation.
If the Express Steam
®
option has been installed, the
AutoFlush will drain for ten minutes then refill with fresh water
to begin the pre-heat cycle.
INSTALLATION INSTRUCTIONS

accordance with applicable national and local codes. Unit drains
by gravity. A drain line that is lower than the AutoFlush
®
