IMPORTANT: The following general information should be used in conjunction with
consultations with your architect, designer and contractor in determining all factors necessary
in providing a suitable and safe steam room.
Read these instructions before installation or service. Although this steambath generator
has been fully qualified for shipment by SAWO, 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 sized for the steambath room. Pay particular
attention to room volume and construction. If any questions, please refer to SAWO sizing
guide enclosed (see page 13).
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 (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: SAWO units are designed to function using only SAWO controls. Both should be
installed in strict accordance with the specific instructions contained in the manuals provided.
A separate manual is provided for the installation of the SAWO controls as well.
Electrical shock hazard. SAWO AS steam generators are connected to 220-240V
(One Phase models only: STS45-1,STS60-1, STS75-1and STS90-1), or 380-430V (Three Phase
models only: STS45-3, STS60-3, STS75-3, STS90-3, STS120-3and STS150-3) line voltage and
contain live electrical components. All installation and service to be performed by qualified
and licensed electricians and plumbers only. Installation or service by unqualified persons may
void the warranty.
The Steam Room must be fully enclosed, complete with walls, door, flooring and ceiling.
We recommend rubber linings (e.g. gaskets) for the door to effectively seal the heat and
contain the steam inside the Steam Room.
If tiles are used for the flooring or some other smooth surface material, provide suitable
anti-skid strips or rubberized mats to prevent slipping resulting to injury.
Materials used for the walls and ceiling should have water-resistant, non-corrosive surfaces
such as tiles, marbles, molded acrylic, or other non-porous materials.The ceiling should be
dome-shaped to prevent the dripping of condensate. If using an acrylic, a fiberglass or other
non-heat resistant materials are to be used as part of the Steam Room enclosure.
A drain must be provided in the flooring.
Heating, venting or air conditioning devices should not be installed inside the Steam Room.
Steam Room windows should be double paned.
Limit the Steam Room ceiling to a height of 2.5 meters. Exceeding 2.5m will require a
higher-rated steam generator.
SAWO strongly recommends for the“WARNING”(when to or not to use the Steam Room) to be
posted in a conspicuous place near the Steam Room.

Optional Tandem Cable - for connecting 2-5 steam generators in tandem
1. Turn on control. Follow specific instruction sheet provided with controls.
2. Steam will begin to appear in 5 minutes at the steam head. Steam will shut off when desired
temperature is reached and will automatically resume when room temperature drops below
set point.
3. Steam will shut off automaticaly when control counts down to zero. to shut steam off manually,
turn control OFF.To clear steam from enclosure area, turn shower on before opening door.
4. If unit does not start and control does not turn ON (control display does not light up) then turn
breaker off for twenty seconds and try again.
Refer to specific instruction sheets for installation, operation and maintenance of optional
equipment and accessories.
SAWO steambath generators require little maintenance. Other than periodic draining,
maintenance procedures are minimal. Every 2 months, or more often in "hard" water areas, the
manual drain valve should be opened fully flushing out accumulated materials, salts and other
particles which are naturally by-products of boiling water.
NOTE: Flush a minimum of two hours after the control has been turned off to insure that the
water has cooled.
Draining immediately after a steam cycle may expose PVC and other piping
to high temperature water. Check local requirements. The unit will refill automatically when
the control is activated again. In areas of very hard water, a SAWO automatic drain
system is recommended for generator longevity.
