Location of the steam generator has to be near the steam room. Place it within 7.5 meters
to the steam room.
Provide a level surface to install steam generator. Side hole slots are provided for wall
mounting. Make sure that the steam generator is secured and is level when mounted on the
wall.
The steam generator must not be installed outdoors or areas that may damage the unit due
to climate conditions.
Do not install the steam generator or plumbing lines in unheated attic or any locations where
water could freeze.
The steam generator must not be installed in areas near flammable or corrosive materials
or chemicals such as gasoline, paint thinners, chlorine or the like.

Disconnect steam generator from main supply before opening generator’s covers. Only
licenced electrician or professional maintence person can open covers and do cleaning.
Use adjustable wrench to deattach 3 wires from level probe. Make sure that when connect-
ing wires back, wires are connected to right probes
Use adjustable wrench to remove level probe. Clean tip of the pins from impurities using
sandpaper. Don’t damage plastic coating on pins. If coating is damaged, replace level
probe. Tighten level probe by hands and use adustable wrench only for final tightening.

Disconnect steam generator from main supply before opening generator’s covers. Only
licenced electrician or professional maintence person can open covers and do cleaning.
Clean level probe as stated in 2.a to 2.b.
Remove temperature fuse and tank temperature sensor from terminal block.
d.
e.
Remove heating elements and clean deposits from the elements.
Remove deposits from bottom and sides of the tank. Open bottom plug to wash away
deposits. Don’t use autodrain valve since big particles can block autodrain valve.
f.
Attach bottom plug and use teflon pipe seal if needed
g.
Attach heating elements. Make sure that temperature fuse and tank tempesensor are on
the top of heating element. Inserting heating element upside down will prevent the tempera-
ture fuse from working

Decalcifying Solution
Maintenance
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.
< 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
Frequency for decalcification:
Unit dH where 1 dH is 10 mg calcium in 1 liter of water
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.
SAWO Decalcifying Solution can be used for decalcification. Follow these guidelines to
perform preventative maintenance of the steam generator.
1. Decalcification
Turn on the steam generator and wait until
water inside the tank starts to boil. Turn off
the generator.
Remove the cap of angled tube in the steam
outlet piping. Before opening, make sure
that the generator is off. Cool down the
angled tube with wet cloth if needed.
Pour the solution into the water tank. Do it
slowly enough to prevent solution to flow
inside the steam pipe.
Close the cap firmly and let the solution stay
in the tank for 30 mins. Do not switch the
generator on.
Drain the water tank by one of the following
ways:
Repeat the step 5 two more times.
Press "Standby" button shortly to
activate standby mode and then press
again "Standby" button for more than 3
seconds to start auto drain.
Manually open the drain valve by pulling
the lever down.
