5. Install the Water Supply and Steam Line
WARNING: Risk of personal injury or property damage.
Do not plumb the pressure relief valve
into the steam line. Plumbing the pressure relief valve into the steam line can create a hazard if the
steam line is blocked or obstructed.
WARNING: Risk of scalding.
Do not plumb a trapway, shut-off valve, or pressure relief valve into
the steam line. Plumbing the pressure relief valve into the steam line can be hazardous, if the steam
outlet is capped.
WARNING: Risk of scalding.
Do not connect the drain valve outlet to the steam line. Ensure that
there are no valleys or dips in the steam line.
WARNING: Risk of personal injury or property damage.
Do not direct the pressure relief valve to
the enclosure. In the event the pressure relief valve activates, the hot water may spray causing
burns to the user and/or damage to the enclosure. Therefore, the pressure relief valve should be
directed to an area where damage will not occur from contact with hot water and should conform
to national and local plumbing codes.
Install the Water Supply Line to the Generator
NOTE:
For all NPT threaded connections, use pipe tape or pipe sealant. Do not overtighten the fittings.
Connect to an existing cold water line, and run a 1/2
″
cold water line to a shut-off valve before the
in-line water filter.
Before final connection to the steam generator, flush out the water supply line into a large pail. This
removes any debris, silt, sand, or other material that may be in the line. Make sure that the filter
screen is in place in the water inlet tube.
Install 1/2
″
copper tubing with a union fitting (supplied with the steam generator) located as close
as possible to the steam generator.
