MAINTENANCE
Decalcification
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 filter and water softener. They are connected
to the water source of the steam generator’s water inlet.
SAWO Decalcifying Solution can be used for decalcification. 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”. Confirm by pressing
“OK”.
Next process shows that water is filled in the
tank. After water is filled, 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

burns!
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 decalcification:
Unit dH where 1 dH is 10 mg calcium in 1 liter of water
< 3 ºdH = very soft water, decalcification every 500 operation hours
3-6 ºdH = soft water, decalcification every 100 operation hours
6-9 ºdH = hard water, decalcification every 50 operation hours
9-18 ºdH = very hard water, decalcification every 30 operation hours
