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 intended to be operated with SAWO Controls only, and are to
be installed strictly in accordance with the specific instructions contained in this manual and
as supplied in the manuals provided with the controls.
Electrical shock hazard. SAWO steam generators are connected to 220-240V
(One Phase models only: STR45-1,STR60-1,STR75-1 and STR90-1), or 380-430V (Three Phase
models only: STR45-3, STR60-3, STR75-3, STR90-3, STR120-3 and STR150-3) 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.
Steam room must be completely enclosed, with full walls, door,floor and ceiling.
It is recommended that a gasketed door is used for heat sealing and steam containment.
If tile-type or other smooth surfaced flooring is used provide suitable anti-skid strips or
equivalent, to prevent user slipping and injury.
Walls and ceilings must be constructed of water-resistant, non-corrosive surface, such as tile,
marble, molded acrylic, or other non-porous material. The ceiling should be sloped to prevent
dripping of condensate.If acrylic, fiberglass or other non-heat resistant materials are used as
part of the steamroom enclosure.
Provide a floor drain.
No heating, venting or air conditioning devices should be installed inside the steam room.
Windows that are part of the steamroom should be double paned.
Try to limit steamroom ceiling height to 2.5m. Exceeding 2.5m may require a higher-rated
steam generator.
SAWO strongly recommends that a warning be posted in a conspicuous location near the
steambath.

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.

The Remote Temperature Probe is for use with SAWO Control only. Do not
use any other controls. Do not use any other temperature probe with the SAWO control.
Noncompatible products may result in an inoperative control and a hazardous condition.
Install the SAWO Control according to the installation and operation
instructions supplied with the control. Failure to do so may result in an inoperative
control and a hazardous condition.
1. Determine the location of the Remote Temperature Probe.
The Remote Temperature Probe must be installed:
a. On a vertical surface
b. 1.2-1.5 meters above the floor
c. Away from the steam head
d. Not exposed to direct steam emission.
The probe has an integral 9 meter
cable. Insure that the probe and/or
steam generator are located accordingly.
Contact a SAWO technical service
representative if a longer cable is
required.
2. Drill an 8mm hole in the wall as
shown in Diagram 1. Do not
oversize or undersize the hole.
Clean area thoroughly.
3. Remove the knock-out from the
steam generator jacket as shown in
Diagram 2.
4. Insert the remote temperature
probe cable through the knock-
out and connect to the
connector on the steam
generator printed
circuit board marked "TEMP
PROBE" as shown
in Diagram 2.
