BEFORE INSTALLING
IMPORTANT
Take a minute to read these instructions before installing or servicing. Although this MS
steambath generator has been fully qualified for shipment by MR. STEAM, the following must
be reviewed for proper, safe and enjoyable steam bathing.
-
Verify that the model and accessories are correct, including incoming line voltage.
- Insure steambath generator has been correctly selected for the steambath room. Pay
particular attention to room volume and construction. If any questions, please refer to
MR. STEAM sizing guide enclosed. (see page 9)
-
Marble or glass walls or ceilings, or exterior walls "ENLARGE" the room's size,
requiring a generator larger than one based only on the room's cubic foot (L x H x W)
volume.
-
The physical size of the unit, clearance for plumbing servicing and its distance from the
steam room must all be considered before
final installation.
•
IMPORTANT
MR. STEAM units intended to be operated with optional accessories, such as digital timer
and/or temperature controls, are to be installed strictly in accordance with the specific
instructions supplied with these optional accessories and the information contained in this
manual.
STEAM ROOM REQUIREMENTS
1. Steam room must be completely enclosed, with full walls, door, floor and ceiling.
2. It
is
recommended that a gasketed door is used for heat sealing and steam containment.
3. If tile-type flooring is used, install anti-skid strips or equivalent, for safety.
4.
Walls
and ceilings must be covered with water-resistant, non-corrosive surface, such as
tile, molded acrylic, fiberglass, etc.
5. Provide a floor drain.

LOCATING THE STEAM GENERATOR UNIT
Select a location as near as possible to the steam room. Typical locations include: closet, vanity
cabinet, insulated attic or basement.
1. For best performance locate steambath generator within 20 feet of steam room.
See page 9 for guidance if generator is greater than 20 feet from steam room.
2. Do not install steambath generator inside steam room.
3.
Do not install steambath generator outdoors.
4.
Do not install steambath generator in unheated attic or basement where water could freeze.
5. Do not install steambath generator near combustible or corrosive materials and chemicals.
6.
Install steambath generator on a solid and level surface.
7.
Install steambath generator in an upright position only.
8.
Provide access to top and ends of steambath generator for servicing.
9.
Steam line, safety valve and drain valve become hot during operation. Provide appropriate
protection.

INSTALLATION
Plumbing
All plumbing shall be performed by a qualified plumber and in accordance with applicable
national and local codes.
-Use unions on all pipe connections.
-Use only brass piping or copper tubing
-Do not use black, galvanized or PVC pipe.
Water Supply - (3/8" NPT)
1.
Connect hot or cold water line. Hot water line is preferable. Hot water should not
exceed
160"
F.
2.
Provide a shut off valve in the supply line.
3.
Do not overheat inlet solenoid valve with solder connections. Overheating will damage
parts.
4.
Flush inlet water line thoroughly before making connection to unit.
5.
Strainer is required if there are solid particles in the water.
6.
Incoming water supply should not exceed 120 psig. For best performance, water pressure
should be 15 to 20 psig.
Steam Outlet - (1/2" NPT)
1.
Do not install a valve in steam line. Flow of steam must be unobstructed.
2.
Use 1/2-inch brass or copper pipe from unit to steam head.
3.
Insulate steam line.
4.
Pitch steam line to avoid valleys and trapping of condensate.
Steam Head
1.

Locate steam head 6 to 12 inches from floor, except:
-
For tub/shower enclosures, install steam head 6 inches above tub top ledge.
-
When used in shower stall with acrylic or other non-heat resistant floors. install steam
head 20-30 inches from floor or use a MR. STEAM steam shield MS-103412.
2.
If steam room is provided with seat(s), locate steam head as far away from seat as
possible.
3.
Install steam head with steam emission slot facing downward.
4.
CAUTION - To preserve steam head finish, do not use wrench or other tools to tighten.
Hand tightening is sufficient.

All electrical wiring shall be installed by a qualified electrician, in accordance with local and
national codes.
Power Wiring - SEE "INPUT POWER" DIAGRAMS
1.
Check power voltage. Use 240V rated-unit when supply is greater than 208V. (Most
homes have 240V, 1PH service available.)
2.
Use minimum 90 deg. C/300V copper conductors only, sized in accordance with National
and Local electrical codes for the amps in chart below.
3.
Connect equipment grounding wire to ground terminal provided.
4.
Install a separate circuit breaker between supply and unit.
5.
On single phase units, use two-wire supply source with ground. Neutral (white wire is not
required).

CHECK OUT AND OPERATION
•

1. Turn on SMART/ONE.
-
When using standard SMART/ONE control, follow specific instruction sheet provided
with controls.
-
When using optional digital timer and/or temperature controls, follow specific instruction
sheets provided with controls.
2.

Steam will begin to appear in a few minutes at the steam head.
-
When the installation includes an optional air switch, press button once and release if no
steam appears after 5 minutes.
-
When system is equipped with an "optional room temperature control or digital
timer/temperature control," steam will shut off when desired temperature is reached and
will automatically resume.
3.

Steam will shut off automatically when SMART/ONE counts down to zero.
-
To shut steam off manually, push optional air switch once or turn off SMART/ONE.
•

- To clear steam from enclosure area, turn on shower before opening door.
OPTIONAL EQUIPMENT
Refer to specific instruction sheets for installation, operation and maintenance of optional
equipment and accessories such as SMART/ONE, SMART/PLUS, SMART/REMOTE,
AUTOFLUSH, etc.
MAINTENANCE
MR. STEAM steambath generators are designed for unattended operation and require little
maintenance. Other than periodic draining, maintenance procedures are not required. Every 2
months, or more often in "hard" water areas, the drain valve should be opened fully flushing
out accumulated materials, salts and other particles which are natural by-products of boiling
water. Note: For best results, this should be done immediately after using the steambath
generator, while contents are still hot and with the control off! The unit will refill automatically
when power is reapplied. In areas of very hard water, a MR. STEAM autoflush system and
water treatment is recommended for generator longevity.

Five Easy Steps To Properly Select . . .
"The Intelligent Steambath" for Your Home
The MR. STEAM model selected depends on the steam room volume and the type of construction used.
1)
Measure the Length, Width and Height in feet of the steam shower or tub/shower being used.
L ,W
2)
Multiply the Length X Width X Height to give you the room
volume = BASIC CUBIC FEET

(a)
3)
If the interior wall construction material within the steam area is composed of natural
marble, stone, slate, glass block or concrete, place on line (b) the same figure
appearing on line (a).

(b)
4)
TOTAL (a) AND (h) TO OBTAIN (c).

(c)
5)
Increase (c) by 15% for each of the design features noted below
ONLY
if they describe your steambath
installation:
•
One exterior outside wall

(d)
•
Tile on mud wall

(e)

•
An extra glass panel in addition to the door

(f) 
•
A cast iron tub

(g)
•
For steambath rooms higher than 8 ft..
please add 15% for each foot above 8 ft.

(h)
•
If generator is more thant 20 feet from steambath
room, add 15% for every 20 feet distance.

(I)
ADD LINES (d) THRU (i) TO LINE (c) = (i) TOTAL CUBIC FEET REQUIRED
Compare the cubic foot requirements (i) to the selection chart on hack of page 6 and select the appropriate model.
If the total cubic feet required (i) is two times or more the value noted in position (a), we strongly recommend that
you specify either an optional Digital Timer & Temperature Control or a Digital Temperature Control.
It is important to specify the correct voltage. Standard voltages are 240 Volts, single phase and 208 Volts, single
phase.
IMPORTANT
The above selection formula for sizing the steambath generator are recommendations only. Because of all
the numerous variables in construction, materials, and insulation (values) these sizing instructions and
specifications should he considered as guidelines only.
It is best that you consult your professional bath planner to evaluate the particular requirements before a
MR. STEAM unit is selected.
MR. STEAM personnel will review the appropriateness of the unit selected as long as We receive complete
information, including working drawings, specifications, and pertinent electrical and construction details
from the owner, architect, or engineer. Otherwise, the manufacturer disclaims responsibility for the sizing
of a unit selected.
