6. Install the Water Supply Line 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 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 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 3/8″ 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.

Install 3/8″ copper tubing with a union fitting between the in-line water filter and the water inlet to the steam generator.

Connect the water supply line to the steam generator.

Make sure that the water drain valve on the generator is closed.

Install the Steam Line

WARNING: Risk of scalding. Do not locate the steam head near a seat or bench or scalding may occur upon contact with the steam head.

NOTICE: Never run the steam line down, then up. Running the steam line down and then up will create a steam trap, blocking the flow of steam. The steam line should run up to the steam head from the steam generator, at a pitch of 3/8″ (1 cm) to 1/2″ (1.3 cm) per 12″ (30.5 cm) of pipe.

NOTICE: Provide clearance between the back wall and the elbow leading into the steam housing. The elbow must not contact any wall material.

NOTICE: Provide clearance between the steam line and surrounding surfaces.

NOTICE: Do not apply excessive heat to the generator connections when you solder connections. Do not apply flux or acids directly to the steam generator, as damage to the seals, plastic components, and trim finish may result. Do not apply petroleum-based lubricants to the steam generator components, as damage may result.

NOTE: For all the threaded connections, use thread sealant tape or pipe sealant. Do not overtighten the fittings.

NOTE: Use 1/2″ copper tube for the steam line.

NOTE: Always install a union fitting as close to the steam generator as possible.

Add blocking behind the desired steam head location.

Install and secure a 1/2″ NPT elbow to the blocking directly behind the desired steam head location.
