Before Installing
Use the following information together with the consultation of your contractor, architect
or designer in determining all factors necessary in providing a suitable and safe steam
room.
Check that the supply voltage is suitable to your steam generator.
Ensure that the steam generator kilowatt corresponds to the volume of your steam room.
Refer to Technical Data (Page 13).
The voltage of the light output is 230VAC. Sawo
recommends to use less than 50V for the steam
room lightning. Use appropriate transformer for
lower voltages. Sawo is not responsible of
WARNING damages caused by using higher voltage inside
the steam room.
Steam Room Guidelines
1. The Steam Room must be fully enclosed, complete with walls, door, flooring and ceiling.
2. Rubber linings (e.g. gaskets) are recommended for the door to effectively seal the
heatand the steam inside the Steam Room.
3. If tiles are used for the flooring or some other smooth surface material, provide
suitable anti-skid strips or rubberized mats to prevent slipping resulting to injury.
4. Materials used for the walls and ceiling should have water-resistant, noncorrosive surfaces such as tiles, marbles, molded acrylic, or other non-porous
materials. The ceiling should be dome-shaped to prevent the dripping of condensate.
5. A drain must be provided in the flooring.
6. Heating, venting or air conditioning devices should not be installed inside the
Steam Room.
7. Steam Room windows should be double paned.
8. Limit the Steam Room ceiling to a height of 2.5 meters. Exceeding 2.5m will require
a higher-rated steam generator.
9. Floor drain for the steam generator must be available for maintenance.

Before installation main supply of the generator must be switch off from the
circuit braker.
The temperature sensor comes along with the SAWO steam generator. It is recommended to use only Sawo temperature sensor with Sawo generator as it may otherwise not function correctly.Temperature sensor wiring should not be routed near
power cables or hot areas as it may cause electronic interference or damage to the
wires.
The sensor has an integrated 9-meter cable. If longer cable is
needed use 2 x 0.5 mm2 to 2 x 1.0mm2 cable for extension.
(for illustrative purpose only)
1. The temperature sensor has to be installed:
Height 1.2-1.5 meters above the floor away from the steam
head so that the steam will not hit the sensor directly.
2. An 25mm hole is required to insert the temperature
sensor. Do not create bigger or smaller hole. Clean
the hole before inserting the sensor.
3. Make a hole in the cable lead-in on the side of
the generator to pull the cable through. Connect
the cable in the terminal block marked as
"TEMP". See figure 2.

Installing Control Unit
SAWO Steam Control sets the temperature of your steam room. Mount the steam control
unit on an accessible area outside the steam room. It is recommended not to place the
steam control near to showers or similar wet places.
Never attempt to modify or to fix the steam control. Ask your licensed technician or your
nearest service centre for repair.
Before installation mains supply of the generator must be switch off from the circui breaker.
Installation Instructions
Check the most suitable area to place your steam generator control. The control and the
steam generator should be accessible for the user and maintenance. Do not install the
control unit inside the steam room! The cable of the control is 7.5 meters.
Mount the control in the wall, according to the specifications given below. Follow illustration.
NOTE
If the control is attached to a
concrete wall, provide a
control holder or equivalent
to mount the control into it.

Connection of SAWO Control to the PCB.
Before installation make sure that the generator is disconnected from the mains by switching off
the circuit breaker
1.
Unscrew PCB cover on the side of the generator to get access on the PCB.
2.
Guide the RJ12 control cable through the cable lead-in hole on the side of the generator
and then behind the side panel as described in the drawing below to reach RJ jacks on the
corner of PCB
3.
Note that there are two black RJ jacks on the board. One is for the control cable and the
other one for the optional slave unit. The control cable and slave cable can be connected
to either of these jacks, the order is insignificant.

Troubleshooting
If an error occurs, the steam generator will be switched off. There will be a warning beep
to alarm the user every 2 seconds. The code for the error will be displayed blinking in the
control panel, see the table below.
Please note, only a qualified electrician or maintenance personnel are allowed to make
the service operations and repairs!
If an error occurs in one of the slave units, error message is followed by slave number. For
example: E1 -> S2 -> E1 ->S2... Pressing ON/OFF button disables the slave and rest of
the generators can operate normally.
Possible errors are:
Code
E1
Problem
Temperature sensor 1
not connected.
E2
Temperature sensor 1
short circuit.
E3
Temperature sensor 2
not connected.
E4
Temperature sensor 2
short circuit.
E5
Temperature fuse defect.
Solution
Check the wire between the sensor and the
control unit.
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.
22
Problem
Solution
Check that the drain valve is not blocked.
Clean the level probes. If no problem can be
found, contact the retailer.
E6
Water level too high and
operation not permitted.
E7
Water level too low and
operation not permitted.
Check that water supply is open and there is
enough pressure. Check solenoid valve.
