3.1. Prior to Installation

Prior to installing the heater, study the instructions
for installation, as well as checking the following
points:
Is the output and type of the heater suitable for
•
the sauna room?
The cubic volumes given in table 2 should be fol-
lowed. See item 2.3.
Are there a sufficient number of high quality
•
sauna stones?
Is the supply voltage suitable for the heater?
•
The location of the heater fulfils the minimum
•
requirements concerning safety distances given
in fig. 4 and table 2.
It is absolutely necessary to ensure that the instal-
lation is carried out according to these values. Ne-
glecting them can cause a risk of fire.
Only one electrical heater may be installed in
•
the sauna room.
The heater should be installed so that the
•
warning texts can also be read without diffi-
culty after the installation.
L heaters have not been approved to be in-
•
stalled in a recess in the wall or floor.

3.2. Fixing the heater on the floor

The heater is fixed to the floor at its two legs, at
the legs' fixing points.
Before fixing the heater, the minimum safety dis-
tances to combustible materials must be taken into
consideration. See Table 2 and Figure 4.

3.3. Safety Railing

If a safety railing is built around the heater, the mini-
mum distances given in figure 4 must be observed.

3.4. 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 on the sauna wall. The junction
box must be splash-proof, and its maximum
height from the floor must not exceed 500 mm.
The connection cable must be of rubber cable
•
type H07RN-F or its equivalent.NOTE! Due to
thermal embrittlement, the use of PVC-insulat-
ed wire as the connection cableof the heater is
forbidden.
If the connection and installation cables are
•
higher than 1000 mm from the floor in the sau-

na or inside the sauna room walls, they must
be able to endure a minimum temperature of
170 °C when loaded (for example, SSJ). Elec-
trical equipment installed higher than 1000 mm
from the sauna floor must be approved for use
in a temperature of 125 °C (marking T125).
The wiring diagrams are included in the control
•
unit's installation instruction.
Further instructions concerning exceptional
•
installations can be obtained from local electri-
cal authorities.

3.4.1. Installation of Control Unit and Sensor

Detailed instructions for the installation of both the
unit and the sensor are delivered with the control
unit.
The sensor must be installed exactly in the
specified place. Otherwise the heater may not
function properly.
The supply air vent of the sauna room must
not be located near the temperature sensor.
The air flow near an air vent cools down the sensor,
which gives inaccurate temperature readings to the
control unit. As a result, the heater might overheat.
The air vent's minimum distance from the sensor:
omnidirectional air vent: 1000 mm
•
air vent directed away from the sensor: 500 mm
•
The sensor must be installed to the place defined
in these instructions. If the minimum distance is not
fulfilled, ventilation must be changed.

3.4.2. 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)!
