Note
: See Diagram 6 for a typical installation. Additional steam heads may be added to any installation to reduce
steam noise or to provide more steam dispersion around a large room.
For large WWSU15 steamers, we
recommend using 2 steam heads to reduce the noise level while steaming.
Note
:
If steam vents are too close to other surfaces, the steam may be cooled and the surfaces damaged.
d)
At the steam room
: Drill/prepare a 1-3/
8” (35 mm) hole for the
steam line entry. Center the 1/2" copper steam pipe in the hole.
See Diagram 4.
•
Terminate the steam line with a 1/2" NPT male adapter.
•
Stub the line out into the room
3/8” (9,5 mm) from the finished
surface.
•
Secure the steam line to a structural member.
3.
INSTALL STEAM HEAD INSULATOR:
Fill in gap (using 100%
silicone caulk between steam pipe and finished wall surface at point of
entry (see Diagram 4). Apply silicone caulk to the finished wall side of
the steam head insulator (see Diagram 5) and hand-tighten the screw
until it is flush with the wall with the opening pointing down. If a hand
tight fit does not align with the opening pointing down, use Teflon tape
on the steam line threads to adjust the fit.
