3. INSTALLATION:
3.1 Installation instructions for the heater, the temperature sensor and the control unit
- Connection of the sauna heater to the power supply may only be carried out by an
authorised electrician in accordance with the valid regulations.
- A rubber-sheathed cable of type H07RN-F or similar must be used as the connection cable.
- If you want to make use of the temperature control feature, we recommend using a rubber cable
with at least seven wires. The cross-section of the cable and the fuse size are presented in Table 1.
3.11 Connection the power supply cable
- Lay the sauna heater on the floor, with its front facing the floor
- Remove the bottom plate
- Connect the power cable. Do not connect voltage to the heater
before adding the temperature sensor and the controller.
3.12 Installing the temperature sensor
- Install temperature sensor to the wall, above the sauna heater
so it is located 100mm below the ceiling. (see Fig. 2)
- The supply air valve must not be located closer than 1000mm
from the temperature sensor. If the valve is located 500-1000 mm
from the sauna heater, an adjustable valve is needed and
set to channel the air away from the sauna heater. If the
supply air valve is too close to the temperature sensor, the
heater will receive false data and it might result in overheating
the sauna heater.
- If the heater is installed more than 200mm away from the wall, the temperature sensor must be
placed into the ceiling 100mm away from the heaters outer surface.
- Install the temperature sensor on the wall with the screws included in the delivery
(2 pcs. Ø 2,9 x 16).
- The wiring for the temperature sensor can be embedded.
- Connect the sensor to the circuit plate, as shown in Fig. 2.1.
- Connect the end of the conductor, the one with no connector in place, to the temperature
sensor. You can cut the conductor to a suitable length.
