Install the Water Supply Line and Steam Line (cont.)

Fill the steam generator with water and check for leaks.

NOTICE: Steam generators are equipped with an automatic shut-off. The water will stop after the unit is

full. If the water ﬂows out of the steam outlet shut off the water and consult the ″Troubleshooting Guide″

or contact the Customer Care Center using the number located on the back of this document.

If the water supply line exceeds 10’ (3 m) or is exposed to cold areas, insulate the piping with

appropriate insulation.

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.

Cut a hole through the wall material to accept a temporary 1/2″ copper tube nipple.

Add a temporary 1/2″ copper tube nipple.
