6. Install the Water Supply and Steam Lines
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 trap, 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 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 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 Lines to the Generators
NOTE:
For all NPT threaded connections, use pipe tape or pipe sealant. Do not overtighten the fittings.
Connect to an existing cold water line for each steam generator, and run a 3/8
″
cold water line to a
shut-off valve before the in-line water filter.
Before final connection to the steam generators, flush out the water feed line into a large pail. This
removes any debris, silt, sand, or other material that may be in the line.
Install 3/8
″
copper tubing with a union fitting between the in-line water filter and the water inlet to
the steam generators.
Connect the water supply lines to the steam generators.
Fill each steam generator with water and check for leaks.
