Auto Drain Ready Steambath Generators Models: SM-5, SM-7 and SM-9

US

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.

3. Steam Generator Electrical Installation

WARNING: All power to the Steam Generator must be

turned off.

a) Remove the two screws holding the electrical

access cover and remove cover.

b) Locate the supply line knockout. Mount proper

strain 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).

Electrical Installation Instructions

Checklist Models: SM-5, SM-7 and SM-9

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 web site - 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.
