Steambath Generators Models: SMP-12 and SMP-15

Important: Locate Publication No. 199 “Steam Bath Important Safety Instructions”. This publication includes a Warning
label that the contractor must install on the wall near the entrance to the steam room in a highly visible location. This
label and its additional safety information are packaged with the generator in the envelope containing the installation

!

instructions. If it is lost or missing contact Steamist (201-933-0700) for a replacement Publication No. 199. This publica­tion along with all documents must be left with the owner.

NOTE: A “TSC” series control is required to operate the "SMC"
generator.

The Steamist “SMP” Generator operates with only “TSC” series
controls mounted inside and an optional TSX control located
outside the steamroom. It’s small enough in size to be tucked
away using very little space in a vanity, closet, or basement, but
large enough to provide steam for most residential baths.

The Steamist “SMP” Steambath Generator comes factory
assembled, carefully wired and tested.

1. Pre-Installation

a) Proper electrical supply (208 or 240 Volt): See rating

label on Steam Generator and Chart on page 4.
Determine proper size of wire, voltage, amperage, and
phase for the Steam Generator. 90°C copper wire is
required for generator connection.

b) 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) 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.

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.

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) Insert ground wire into grounding lug located

on the right side of the electrical compartment
and secure.

CAUTION: Be sure the ground wire does not
come in contact with a live electrical part.

e) Locate the terminal/fuse block in the upper portion

of the electrical compartment. Insert power wires
into the power lugs on the front of the terminal/fuse
block and secure.

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 auto DRAIN

connection J11 on the printed circuit board (see
Figure 2).

Checklist

Electrical Installation Instructions

Models: SMP-12 and SMP-15

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.

The Electrical Instructions must be given to the homeowner for future use.

NOTE: Unit must be wired with 90°C

copper wire in a suitable raceway, or, if
local codes allow, provide twist lock plug
on a 90°C copper wire cord from genera­tor to a 250V 2-pole, 3-wire grounding
receptacle (amperage rating as required).
