ELECTRICAL CONNECTIONS:
The steam generator is connected (semi-fixed connection) to the mains power, in accordance with
local installation regulations.

Electrical connections are only to be installed by a licensed electrician.
*) Walls made of heavy materials, such as concrete, brick or stone require a higher output to
generate sufficient heat. Ventilation must also be given extra power.
The required power output can be estimated using the fomula below.
Volume (m3) x K1 x K2 = Required output (kW)
Ventilation K1 = 0.75
No ventilation K1 = 0.52
Acrylic walls K2 = 1.00
Light construction wall: drywall + tile K2 = 1.25
Heavy construction wall: stone, concrete + tile K2 = 1.50
Steam generator 2-phase control: (Not in the special Belgian version)
The steam generator thermal resistors are 2-phase controlled.
Example: The temperature is set for +43 °C. When the temperature reaches +43 °C two resistors
are switched off with a contactor and one remains on to maintain the temperature with a relay on the
circuit board. If the temperature drops 1 °C, all resistors will be switched back on. If the
temperature rises 1 °C, all three resistors will be shut off. This will ensure an even steam output for
the duration of operation.
