3. INSTRUCTIONS FOR INSTALLATION

3.1. Prior to Installation

Prior to installing the heater, read all the instructions

for installation (figure 8), as well as checking the fol

lowing points:

•

The heater volume should be suitable for the
sauna room volume. Table 2 shows the mini-
mum and maximum volumes for each heater
output. A precondition for the given values is
that the sauna room is well heatinsulated.
Walls and ceiling are covered with wood panel.

•

Check that supply voltage and amperages are
available for the heater.

•

The breakers and the connection cables con-
form with valid regulations and their dimen-
sions are in accordance with table 3.

•

The location is suitable for the heater

(

3.2.).

•

Note! Only one electrical heater may be

installed in the sauna room. Multiple heaters

can be installed and used in the sauna room

only if they share the same control unit

(Multidrive)

3.2. Place and Safety Distances

The minimum safety distances are described in

figure 3 and 5.

•

It is absolutely necessary to install the heater

according to these values. Neglecting them

causes a risk of fire.

•

Hot pieces of stone can damage floor coverings

and cause a risk of fire.

The floor coverings of

the installation place should be heat-resistant.

3.3. Heater fence

It is necessary for safety and should be constructed

of softwood to match sauna interior. See figures

3 and 5 for clearances from sauna heater. Fence
should be attached to wall and should not be placed
higher than top of heater below rock line.

3.4. Installation of the Control Unit and Sensor

•

The control unit includes detailed instructions
for fastening the unit on the wall.

Install the sensor (WX248), which comes with

the heater, as shown in figure 6.

Do not place the supply air vent so that the air

flow cools the temperature sensor. Figure 4.

The heater may only be connected to the electrical

network in accordance with the current regulations

by an authorised, licensed professional electrician.

unit’s installation instruction.

Further instructions concerning exceptional installa-

tions can be obtained from local electrical authorities.
1. Remove heater from carton and place in

proper location in sauna room. Observe proper

clearances as per figures 3 and 5. After final

hookup, electrical contractor should secure

heater to floor with at least two screws or

bolts.

2. See applicable wiring diagram for heater model

(figure 7, 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.

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”
