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.
Optional Equipment
Refer to specific instruction sheets for installation, operation and maintenance of optional
equipment and accessories.
Maintenance
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.
10
WARNING ! 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.
2. Plumbing to be performed by a qualified licensed
plumber and shall be in accordance with applicable
national and Local Codes. Unit drains by gravity.
A drain line that is lower than Automatic drain
assembly must be available. The Automatic drain
valve outlet is threaded 15mm. Check plumbing
code for receptor, trap and vent requirements.
3. Use copper or brass nipple 15mm x 90mm
or longer (not supplied) to connect the Automatic
drain valve (end "B") to the Drain Valve (valve end

Place the drops into the SAWO steamhead recess prior to turning on the
steambath. Do not place drops in a hot steamhead as SERIOUS INJURY CAN RESULT IF YOU
DO NOT FOLLOW THIS WARNING.
!
CAUTION ! Start with one drop to gauge strength and suitability. Limit to a maximum of a few
drops during a steambathing session. Some people may find that the aroma makes dizzy and
the user should exit the steam bath IMMEDIATELY. If skin irritation occurs stop using the oils
immediately. Remove any excess oil by washing in mild soap and water. If ingested, rinse
mouth with water. Administer water or milk to dilute. contact a physician immediately.

Installing the Remote Temperature Probe
Installing the Remote Temperature Probe (cont.)
for SAWO Controls
5. Route the end of the temperature probe cable with the
temperature probe through the wall into the steam room
as shown in Diagram 3.
CAUTION ! 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.
CAUTION ! 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
