Steambath Generator Model: SM-11
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. 90°C copper wire is required for generator connection.
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.
relief into knockout hole (see Figure 2: Internal
Electrical Connections).
c) Strip back power cable’s outer insulation jacket eight inches and insert into Steam Generator.
Strip back insulation ½" from the three (3) incoming wires (two power and one ground).
d) Connect incoming ground wire to floating green pigtail labeled “GND.”
CAUTION: Be sure the ground wire does not come in contact with a live electrical part. e) Connect incoming power to floating black pigtail leads labeled “L1” and “L2” (see Figure 2: Internal
Electrical Connections).
f) The Steam Generator is ready for operation once the installation of the controls is completed (refer to separate Installation and Operating Instructions).
4.
Optional Auto Drain Valve Connection a) Open knockout for Auto Drain Valve conduit connection.
b) Route flexible conduit from valve to knockout
and secure. c) Connect two wires from valve to the two place terminal strip provided (see figure 2).

less than 250V and proper amperage. Refer to chart on page 4 for amperage rating.
After the walls are complete, the Steam Generator and

Electrical Installation Instructions
Checklist Model: SM-11
Before starting, insure that the conditions of the following checklist have been met:
The proper size Steam Generator has been selected by using the sizing page in the “Full Line Brochure,” “Pricing
Guide,” or “The Generator Sizing Guide” in the Residential Systems/Steambath Product Information section of the Steamist website - www.steamist.com.
CAUTION: An improperly sized Steam Generator will
NOT produce the amount of steam necessary to reach selected temperature.
The proper voltage Steam Generator has been selected
(i.e., 208V or 240V). A 208V Generator operating on
240V will damage the heating element, and a 240V
Generator operating on 208V will result in a 25% loss of power.
The Steam Generator is installed in an upright position.
The proper sized 90°C copper wire and circuit breaker have been used.
The circuit breaker is NOT a GFI (Ground Fault
Interrupter) type.
The Steam Generator is properly grounded.
The circuit breaker or disconnect switch is on.
Water supply is open to the Steam Generator.
