Installing The Heater; Electric Heater Insulation Resistance - Harvia HPC(S)7U1H Owner's/Operator's Manual

3.6. Installing the Heater

See figure 8.
1. Install the wall-mounting device.
2. Connect cables to the heater.
3. Place the heater and adjust the heater
vertically straight using the adjustable legs.
4. Use fixing kits (2 pcs) to fix the heater to
sauna's structures.

3.7. Electric heater insulation resistance

When performing the final inspection of the electri-
cal 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)/GFI
(Ground Fault Interrupter)!
