Heater Installation
It is recommended that the heater is
placed on the wall nearest to the door.
The air circulation created by the door
should work together with the hot air
generated by the heater. For safety and
convenience, follow the minimum safety
distances as provided in Fig. 1. Follow
the cubic volumes given in Fig.6. Do not
install the heater to the floor or wall
niche. Two heaters can be installed in
the sauna (Tandem Type). Check
Electrical Diagram in Fig.6.
Be sure to build a strong foundation for
the mounting rack (e.g. cross struts in
sauna paneling) or reinforce the wall
with a thick board to prevent the heater
from collapsing. Attach the heater to the
wall with the aid of the mounting rack.
Screws are provided for fastening of the
rack to the wall.
To affix the heater to the rack, fit the
bolt provided into the heater to the rack
hole’s end. The heater is now attached
to the wall mounting rack. You can
adjust the angle position of the heater
by adjusting the Leveler Rod located on
the lower part (Fig.2).
A certified electrician must do the
installation of the heater to ensure
safety and reliability. Improper electrical
connections can cause electric shock or
fire. Refer to the Electrical Diagram in
Fig.6.
An electrical supply cable must be
connected to the terminal block inside
the control unit. The cable must be
HO7RN-F type or its equivalent. For NS
models cable from the separate control
unit is also to be attached into the
heater terminal. Refer Electrical
Diagram (Fig.6).
To connect the cable, slice the plastic
cover at the bottom of the heater to
create a hole (Fig.3). Insert the cable
inside the unit. Remove the bottom
cover of the unit by unscrewing it.
Connect the wires into the terminal
block located inside (Refer to the
Electrical Diagram, Fig.6). Put back the
bottom cover and screw it.
For Tandem type, extra wire (not
supplied) is needed to connect both
heaters then into the separate control
unit (Fig.4).

Remove the carton from the heating elements and behind
the serial number (between outer and inner cover) before
installing the heater as it is only intended to protect them

The main purpose of the stones in the
heater unit is to store enough energy to
efficiently vaporize the water thrown on
top of the stones to maintain correct
humidity in the sauna room.
The stones should be replaced
immediately if cracked or broken as they
may collapse resulting to damage of other
stones or property.
It is recommended that all stones should
be rinsed to remove any stains or dust
that can cause unpleasant odour during
the first few times of using the heater.
Follow stone piling instructions on the
illustration Fig.5. D-type stones should be
placed to cover the front of the heater.
The Top Stone is designed with water
pockets. Here you can place liquid scents
to give your sauna bathing a pleasant
scent.
Avoid pouring them while the heater is on,
as it can cause serious burns. Brush the
water pocket and rinse with water after
using scents.
NOTE!
Never use the heater without stones as
it may cause fire. Use only manufacturer
recommended SAWO-stones. Using
unsuitable stones may lead to heating
element damage and will void the
warranty. Never use ceramic stones or
other artificial stones of any type!

Insulation
The sauna must have proper insulation
on the walls, ceiling and door. One
square meter (m²) of uninsulated
surface increases the cubic volume by
approximately 1,2m³ when determining
the power requirement of the heater.
Refer to Fig.7.
Ensure that moisture proofing is
appropriate in sauna room. The purpose
of this is to prevent spreading of
moisture to the other rooms or wall
structure. Moisture proofing must be
placed between heating insulation and
panel. Nordic spruce wood is
recommended for the walls and ceiling
inside the sauna.
TIMER
Control Settings (NB Models Only)
Adjust the temperature of the sauna by
simply turning the operating knob.
Thermostat support automatically the
choosen temperature.
In case the heater overheats, the safety
sensor will automatically stop the heater
even if the timer is on. Find out for what
reason the heater overheated. The
reason for this could be heater´s
location or inappropriate ventilation. If
this occurs, find out the cause and fix
the problem before resetting the safety
sensor. The reset button is located
between timer and thermostat knob.
The timer has 1-8 (white) hours
presetting time and 1-4 (pink) hours
operating time.
To start the heater at once, turn the
knob to anywhere between 1-4 on the
operating time scale. The heater will
start and remain on for the time
selected.
To preset the timer, simply turn the knob
to anywhere between 1-8. When the
specific number of hours is reached, the
heater will start running and stay on for
up to 4 hours if you don´t turn it off
earlier.
TERMOSTAT
The recommended minimum
thickness of the thermal insulation in
the walls is 50 mm and in the ceiling
100 mm.
It is possible to use carton- or
aluminum foil laminate as a vapor
barrier, which is affixed over the
insulation aluminum foil inwards.
Leave at least 20 mm air slot
between vapor barrier and inside
panel.
To prevent gathering of the moisture
behind the panel, leave the slot
between wall panel and ceiling.

Heating of the sauna
Malfunctions
Always check the sauna room before
switching the sauna heater on (make
sure that there is nothing on or near the
heater). When you are using the heater
for the first time, the heater and the
stones may emit smells. Make sure that
the sauna room has been efficiently
ventilated. If the output of the heater is
proper it will take about an hour to
reach suitable temperature (Fig. 10).
The temperature in sauna room should
be between +65 - + 80 °C, according to
the preference of the use. Too powerful
If heater doesn't work, check the following:
That the heater has been switched
to operating time not to the
presetting time.
That the source of electricity to the
heater has been switched on.

Air Ventilation
To have a soothing sauna, there should
be a proper mixing of hot and cold air
inside the sauna room. Another reason
for ventilation is to draw air around the
heater and move the heat to the farthest
part of the sauna. The positioning of the
inlet and outlet vents may vary
depending on the design of the sauna
room or preference of the owner.
The inlet vent may be installed on the
wall directly below the heater (Fig. 10A).
When using the mechanical ventilation,
inlet vent is placed at least 50 cm above
the heater (Fig 10B) or on the ceiling
above the heater (Fig. 10C). Through
these positions, the heavy cold air that is
blown into the sauna is mixed with the
light hot air from the heater, bringing fresh
air for the bathers. In an hour, the
