3.4. Installation of the Control Unit and Sensor
The control unit includes detailed instructions
•
for fastening the unit on the wall.
Install the sensor as shown in figure 6. If the
•
heater is installed further than 150 mm from
wall, the sensor must be installed on the cei-
ling.
Do not place the supply air vent so that the air
flow cools the temperature sensor. Figure 3.

3.5. Electrical Connections
The heater may only be connected to the
electrical network in accordance with the cur-
rent regulations by an authorised, professional elec-
trician.
The heater is semi-stationarily connected to
•
the junction box (figure 7:3) on the sauna wall.
The junction box must be splash-proof, and
its maximum height from the floor must not
exceed 500 mm.
The connecting cable (figure 7:2) must be of
•
rubber cable type H07RN-F or its equivalent.
NOTE! Due to thermal embrittlement, the use
of PVC-insulated wire as the connecting cable
of the heater is forbidden.

If the connecting and installation cables are
•
higher than 1000 mm from the floor in the sauna
or inside the sauna room walls, they must be
able to endure a minimum temperature of 170 °C
when loaded (for example, SSJ). Electrical
equipment installed higher than 1000 mm from
the sauna floor must be approved for use in a
temperature of 125 °C (marking T125).
3.5.1. Electric Heater Insulation Resistance
When performing the final inspection of the
electrical installations, a "leakage" may be detected
when measuring the heater's insulation resistance.
The reason for this is that the insulating material
of the heating elements has absorbed moisture
from the air (storage, transport). After operating
the heater for a few times, the moisture will be
removed from the heating elements.
Do not connect the power feed for the heater
through the RCD (residual current device)!
3.6. Installing the Heater
See figure 7.
1. Connect cables to the heater ( 3.5.).
2. Place the heater and adjust the heater vertically
straight using the adjustable legs. The heater
is fixed to the floor at its two legs, at the legs'
fixing points.
3.7. Replacing the Heating Elements
See figure 8.
