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.
NOTE:
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
1. Plumbing to be performed by a qualified plumber and shall be in
accordance with applicable national and local codes. Unit drains
by gravity. A drain line that is lower than the AutoFlush
®
assembly
must be available. The AutoFlush System valve outlet is
1
⁄2“ NPT.
Check plumbing code for receptor, trap and vent requirements.
2. Use copper or brass nipple
1
⁄2“ NPT x 3
1
⁄2“ or longer (not supplied)
to connect AutoFlush valve (end "B") to the Drain Valve (valve end
“A” and “B” are indicated on bottom of AutoFlush Valve)
DO NOT REMOVE THE DRAIN VALVE
Removal may cause equipment and property damage. If there is
not enough room for the valve, an elbow and a short nipple
(not provided) can be added.
3. Open Drain Valve (handle must be aligned with brass nipple).
4. Connect the AutoFlush System cord connector to the three pin
connector as shown.
DO NOT drain into a steam enclosure or any location
where accidental contact with drain water may occur. In the event of
a power failure the AutoFlush System valve will open and may dis-
charge boiling water causing a scalding hazard.

point below 600 degrees F. DO NOT overheat. Ends of water supply
tubing must be thoroughly clean for a minimum distance of 1" from
