PREFERRED INSTALLATION
DIAGRAM 5: WATER LINES
All plumbing shall be installed by a licensed plumber and conform with local and
national codes.
Materials (locally available):
- 3/8” O.D. copper tube, shut off valves and compression to 3/8” male NPT
adapter for the water supplies to the generators.
- 1/2” copper pipe and unions for the steam lines to the steam rooms and
the tank drains.
- 3/4” copper pipe, fi ttings, and a union for the Pressure Relief Valve drain.
- Tube 100% silicone caulk.
- Pipe compound.
Note: other materials may be required.
1. INSTALL WATER LINE See diagrams 4 and 5.
Run 3/8” copper tube between the nearest cold water line and the WATER INLET fi tting on the generator. Locate a shut-off valve near the generator. Connect this
line to the generator with a 3/8” compression adapter. When tightening this fi tting always use two wrenches so there will be no strain on the water inlet valve. For
better servicability, use a separate shut-off valve for each generator. See diagrams 3 and 4.
2. INSTALL STEAM LINE See diagrams 4 and 6.
At the Generator: Install a 1/2” male NPT sweat adaptor into the generator’s steam outlet. Install a 1/2” union in the steam line near the generator.
Run the 1/2” steam line from the generator to the steam room. Refer to SECTION 2: SELECT MOUNTING LOCATION.
The steam line should enter the room 18” above the fl oor or at least 12” above a tub rim or ledge.
