*Applies to square and round steam heads.
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. Verify 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 Waterline to the Generator
IMPORTANT! The steam generator is compatible with installations that require a water-hammer arrestor or pressure-
reducing valve to achieve optimal performance.
NOTE: For all NPT threaded connections, use pipe tape or pipe sealant. Do not overtighten the fittings.
Connect to an existing cold waterline, and run a 1/2" cold waterline 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. Verify 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.
Connect the water supply line to the steam generator.
Turn ON the water supply, and fill the steam generator with water. Check for leaks.
Check that the water drain valve on the generator is closed.
If the water supply line is exposed to cold areas, insulate the piping to prevent freezing.
