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)!

Resetting the Overheat Protector

If the temperature of the sauna room becomes dangerously high, the overheat protector will permanently cut off the
supply of the heater. The overheat protector can be reset after the heater has cooled down.
The reset button is located inside the heater's connection box (figure 9).
Only persons authorised to carry out electrical installations can reset the overheat protector.
Prior to pressing the button, the cause of the fault must be found.
•
Are the stones crumbled and pressed together?
•
Has the heater been on for a long time while unused?
•
Is the sensor of the thermostat out of place or broken?
•
Has the heater been banged or shaken?
