INSTALLATION OF THE SAUNA HEATER

The following points have to be observed when installing the heater:

- Adhere to the given installation measurements.

- Wood panelling is recommended as material for the walls and ceiling of the sauna.

- Ensure that the panel wall has been reinforced at the point of the fixing screws.

- Only one heater may be installed into a sauna.

- The heater must only be connected to the mains by a qualified person as defined by current

electricity regulations.

NOTE! Prior to switching the heater on, ensure that the sauna room is ready for heating.

CONNECTING THE HEATER TO THE MAINS

The heater is semi-connected to the mains with H07RN-F (VSN) or A07BB-F(VSB) rubber cable.

HEATER STONES

We recommend that the heater stones are cleaned before placing them onto the heater. The largest stones are placed
at the bottom and the smallest on the top. Stones must not be structured too tightly, or air circulation is inhibited. Nor
must the stones be placed so that heat resistance elements become wedged together or against the heater body. The
stones must completely cover the heat resistance elements. The stones have to be replaced at the latest when they
start to crumble, because otherwise the air circulation through the stones is affected. When replacing the stones, new
stones have to be of a high quality.

NOTE!

- The heater stones MUST NOT be placed in the space between the front soapstones and the first resistance
element.

- Before use it must be checked that the soapstones in the heater are undamaged and installed according to
instructions. Otherwise the use of the heater is prohibited. The guarantee does not cover faults due to poor
air circulation caused by small and tightly packed stones. Ceramic stones may damage the heater. The
guarantee of the heater does not cover any damage caused by their use.

INSTALLATION OF THE CONTROL UNIT AND SENSOR ELEMENTS

The control unit is electrically connected via a cable to the heater. The control unit is intended for installation in the
sauna room or outside of it, depending on the model of the control unit. Check the control unit location from the control
unit installation and user instructions.
The sensor is fixed to the wall of the sauna, directly on the middle line of the heater, 40mm from the ceiling. Any
deviation from the given installation measurements will cause a risk of burns.
The temperature limiter in the sensor element cuts off all the heating energy to the heater if the heater temperature
increases to a level where it causes a danger to the wooden parts of the sauna. Once the temperature is reduced the
limiter can be restored by pressing the restore button.

Before pressing restore, the reason for the triggering of the temperature limiter must always be clarified!

FIXING THE HEATER TO THE WALL.

Once the adjustable legs are turned in the
fixing height of the heater, wall rack is 750mm
from the floor. The adjustable legs have a 15mm
adjustment allowance just in case the floor is on
an incline.
Check after fixing to the wall that both adjustable
legs are evenly set against the floor.

The measurement between the fixing holes of the

240 mm

rack to be fixed on the wall is 240mm.

Wall fixing parts:

- locking pieces for the heater (A) 2 pieces

- wall fastener (B) 1 piece

- metal screw 4.2 x 13mm 2 pieces

- cover screw 6 x 40mm 2 pieces

Fit the locking pieces (A) for the heater into the
holes in the back plate so that the entering part
turns upwards.

Fix the wall rack (B) to face the wall so that the
holes where the locking pieces are fixed will be
upwards. The rack can also be fixed directly to
the heater. Mark in advance the locations of the
screws to the wall and, if needed, drill small
guide holes and then fix the heater to the wall
with the screws supplied.

The illustration shows how the wall rack should
be fixed in the heater.

The parts in the heater are fixed to the wall rack
with metal screws.

A heat resistant box (T125 ºC) and leads (T170°C) should be used in all other areas.
The connection box should be in a place where it is easy to service. When placing the
connection box in areas 2 and 3, the local energy board's instructions and regulations
must be checked.

Check electrical safety regulations section 19 concerning electrical heater control and
safety equipment.

Soapstone user manual

As soapstones are used in the heater, it is extremely important that the sauna is correctly heated
the first few times. This ensures that the soapstones will not crack even at high
temperatures.

1. The first heating

*): Set the heater to approx. a 50°C setting for about an hour. Then disconnect

the heater and let the stones cool down.

2. The second heating

*): Set the heater to approx. a 80°C setting for about an hour. Then

disconnect the heater and let the stones cool down.

3. No water should be thrown on the heater during the first heating time to enable the soapstones
gradually to become hardened.

4. After the second heating the heater can be used normally.

5. It is typical of soapstones that they may become coloured during use. The reason for the
colouring can be the high temperature of the stones or the quality of the water thrown on the
heated stones.

*) If the Easy control centre is used, set the heater to the lowest setting for about an hour during
the first time. During the second heating the temperature has to be set a couple of notches higher
than during the first heating. The second heating should also last for about an hour. Then the
heater can be used normally.
