ELECTRICAL CONNECTIONS
The steam generator will be semi-permanently connected to the electricity mains. Local regulations
must be observed.

All electrical connections should be completed by a qualified electrician.
*) Walls of concrete, brick or stone and cold wall lining materials will require a higher power
output to heat the room. Air conditioning and good ventilation may also need more power.
The required power can be estimated using the following formula.
Capacity (m3) x K1 x K2 = Required power (kW)
Ventilation K1 = 0.75
No ventilation K1 = 0.52
Acrylic walls K2 = 1.00
Light wall: board + tiles K2 = 1.25
Heavy wall: stone, concrete + tiles K2 = 1.50
Two-stage control of the steam generator:
The heat elements have a two-stage control. Not 230 V 3~p.
Example:
Set temperature is 43 °C. When this temperature is reached the contactor turns off two elements,
leaving one element connected via relay-switch on the circuit board, ensuring steady temperature
and continuous steam production for the duration of the steam bath. Once the temperature has
dropped by one degree (1 °C), all the elements are switched back on. If the temperature rises by one
degree (1 °C), all the elements will be switched off. .
