Installing the Power Unit › Image 1
Install the power unit in a dry area or sauna room (ambient temperature >0ºC). Note! Do not embed the power
unit into the wall, since this may cause excessive heating of the internal components of the unit and lead to
damage.
Electrical Connections › Image 2
Connect the wiring according to Figure 2. Tables show the wire and fuse sizes, depending on the heater output. For
more detailed installation instructions see the instructions for installation and use of the selected heater
model. Maximum load from control unit to heater is 9 kW.
Power Unit Fuse Faults
Replace a blown fuse by a new one with the same value. The location of the fuses in the power unit is shown in Figure
2.
• If the fuse for the electronic card has blown, there is likely a fault in the power unit. Service is required.
• If the lighting fuse (Figure 2) is broken, there is a fault in the lighting. Check the operation and wiring of the
lighting.
