Steamist SM-12 Electrical Installation Instructions

Steambath Generators
The Steamist "SM" Generator operates with one or two controls
appropriately located inside and/or outside the steamroom. It's
small enough in size to be tucked away using very little space in
a vanity, closet, basement, or an insulated attic, but large enough
to provide steam for most residential baths.
The Steamist "SM" Steambath Generator comes factory
assembled, carefully wired and tested.
NOTE: The SMC-120, SMC-150, TC-125, TC-150, TC-110,
TC-135, DSC-425, and DSP Controls are designed to work with
all Steamist "SM" Generators.
1.
Pre-Installation
a) Proper electrical supply (208 or 240 Volt): See rating label
on Steam Generator and Chart on back page. Determine
proper size of wire, voltage, amperage, and phase for the
Steam Generator. Only UL rated 90°C wire can be used.
b) Dedicated overcurrent protection device, such as an
in-line fuse/circuit breaker required: Fuse/circuit breaker
to be installed must be sized in accordance with chart
on back page. Do NOT install a GFI (Ground Fault
Interrupter) to this equipment (per article 210-8 in the
National Electric Code).
c) Route power supply cable to the location where the
Steam Generator will be installed (before walls are
closed).
2.
Electrical Rough-in
a) At this time read through the installation instructions for
the selected control(s).
b) Route appropriate power cable to the location the
Steam Generator will be installed. If receptacle is
desired, mount the box for the receptacle near the
location of the Steam Generator (see Figure 3: Typical
Installation).
NOTE: The plug and receptacle require a rating of no
less than 250V and proper amperage. Refer to chart on
page 4 for amperage rating.
After the walls are complete, the Steam Generator and
Control can be wired.
