Installation details
Figure 3. The heater's safety distances. Note! If E is higher than E max, then B min. = C min.
NOTE! Due to thermal embrittlement, the use
of PVC-insulated wire as the connection cable of
the heater is forbidden. The junction box must be
splash-proof, and its maximum height from the floor
must not exceed 50 cm.
If the connection and installation cables are higher
than 100 cm 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 100 cm from the sauna floor must be
approved for use in a temperature of 125 °C (mark-
ing T125).
The wiring diagrams are included in the control
unit's installation instruction.
Further instructions concerning exceptional ins-
talla tions can be obtained from local electrical au-
thorities.

3.6. 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 resistors has absorbed moisture from the
air (storage/transport). After operating the heater
for a few times, the moisture will be removed from
the resistors.
Do not connect the power feed for the heater
through the RCD (residual current device)!
