Installing The Heater; Electric Heater Insulation Resistance; Replacing The Heating Elements; Resetting The Overheat Protectors Of The Heater And The Water Reservoir - Harvia HL7U1S Manuel De L'utilisateur/Opérateur

1. Remove heater from carton and place in
proper location in sauna room. Observe proper
clearances as per figures 4 and 6.
2. See applicable wiring diagram for heater model
(figure 8, see control unit manual for detailed
instructions how to connect the heater and
the control unit). Heater must be permanently
installed by using seal tight conduit between
the heater and the wall of the sauna room
(pigtails or plugs are not allowed in the sauna
room). Wiring must be done by a licensed
electrician, who must follow wiring diagram
provided and adhere to local codes. Use proper
AWG rated wire size and use copper wire
suitable for 194 °F (90 °C) within sauna walls.
Use grounding terminals provided in sauna
heater and control unit to properly ground the
equipment as per NEC and local codes.
3. Inside the heater box there are two signs.
Please place the metal "CAUTION" sign on
the interior wall of the sauna room directly
above the heater in a visible place (screws and
nails included). Place the metal "WARNING"
sign outside, on the door of the sauna room.
"MAINTENANCE INSTRUCTIONS" are at the
end of this manual.

ly straight using the adjustable legs.

3.8. 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)!

3.9. Replacing the Heating Elements

See figure 10.
3.10. Resetting the Overheat Protectors of
the Heater and the Water Reservoir
See figure 11. If the temperature of the sauna room
becomes dangerously high, the overheat protector
(1) will permanently cut off the supply of the heater.
The overheating protector (1) can be reset after
the heater has cooled down. Please check that the
stones are piled properly and the sensor is installed
according the installation instructions. See also the
installation instructions for control unit.
If water reservoir empties during the use, the
overheat protector (2) cuts off the steamer power.
The overheating protector (2) can be reset after the
steamer has cooled down.
The reset button is located under the heater.
