INTRODUCTION
There are ve different operation modes in the unit: OFF, ON, Standby, Easy Mode
and Drain. The user can easily switch between different modes making the steam
bathing more convenient.
To use the steam room, the control unit needs to be in ON Mode. In the ON mode,
the steam generator is producing steam and temperature in the steam room is kept
in preferred set temperature with occasional discharge of steam.
However, if the steam room is not used constantly, the generator can be set to
Standby Mode. During the Standby Mode, water and steam room are kept warm
with minimal energy consumption. The generator is able to produce steam shortly
after the unit is switched back to ON mode for the user’s convenience.

INSTALLING THE CONTROL UNIT
Check the most suitable area to place your steam generator control. The control
and the steam generator should be accessible for the user and for maintenance. Do
not install the control unit inside the steam room! The cable connecting the control
unit and the steam generator is 7.5 meters long.
Never attempt to modify or x the steam control. Contact your licensed technician
or your nearest service center for repair.
Before installation, main power supply of the generator must be switch off from
the circuit breaker.
Mount the control unit in the wall according to the specications given below.
Follow the illustrations.
NOTE!
Run the Factory Reset after installing the steam generator for the rst
time or after changing the control panel. See page 8.

Long press OK button if alarm has been settled.
Remote On
Used for automated households. The remote signal is
a potential free contact. The steam generator switches

ENGLISH 17
MAINTENANCE
Decalcication
Tap water contains impurities, for example lime, that can cause calcium deposit and block
the internal parts of the steam generator. To prevent this and prolong the lifetime of steam
generator it is recommended to have a water lter and water softener. They are connected
to the water source of the steam generator’s water inlet.
SAWO Decalcifying Solution can be used for decalcication. Follow these guidelines to
perform preventative maintenance of the steam generator.
Stainless Steel Touch Control:
Turn ON the steam generator.
Go to Settings menu by pressing three seconds
the settings icon. Scroll to the “Decalcifying”
menu and press “Start”. Conrm by pressing
“OK”.
Next process shows that water is lled in the
tank. After water is lled, add decalcifying
solution: Remove the cap of tee pipe in
the over pressure valve piping. Pour the
decalcifying solution into the tank. Return
back the cap to its original position when
done.
After pouring the solution, press “OK” on the
screen. Steam generator will automatically
go through decalcifying process including
draining. After process is done, screen will go
to off state. Fill and drain the tank with water
two times more by switching ON and draining
the steam generator.

WARNING!
Never add the Decalcifying

Use Decalcifying Solution as follows:
For steam generators in commercial use (over 5
hours continuously daily) additional service plan
is recommended twice a year. Please contact
your service center for details.
Frequency for decalcication:
Unit dH where 1 dH is 10 mg calcium in 1 liter of water
< 3 ºdH = very soft water, decalcication every 500 operation hours
3-6 ºdH = soft water, decalcication every 100 operation hours
6-9 ºdH = hard water, decalcication every 50 operation hours
9-18 ºdH = very hard water, decalcication every 30 operation hours

If there is no problem with the wires and they
are correctly installed, check the sensor.
If no problem can be found, contact the retailer.
Check the wire between the fuse and the control
unit. Fuse has probably overheated. The reason
for it needs to be discovered before using the
steam generator again. A new fuse is needed.
If no problem can be found, contact the retailer.
Code Problem Solution
If an error occurs the steam generator will automatically
switch off. A warning beep will alarm the user every 2
seconds. The error code will be displayed blinking in
the control panel, see the table below.
Please note, only a qualied electrician or maintenance
personnel are allowed to make service operations and
repairs! Long press OK button to switch OFF Mode.
For Tandem Connection:
If an error occurs in one of the slave units, error message
is followed by slave number. For example: E1 -> S2
-> E1 ->S2... Pressing the ON/OFF button disables the
slave and rest of the generators can operate normally.
See steam generator manual for tandem connection.
