Installation and Operating Instructions Kalla
1. General safety information
This device is not intended for use by children or persons whose physical, sensory or mental
abilities or lack of experience and knowledge prevent them from using the device safely, without the
supervision of a person responsible for their safety or before they have been instructed on how to use
the device.
Children should be supervised to ensure that they do not play with the device.
This device complies with the requirements of:
Mondex pursues an active policy of product development and continuous improvement. For this
reason, Mondex reserves the right to make changes relating to the design and technical specifications
of their products without prior notice.
Electrical connections may only be carried out by an electrician with valid installation
authorization according to the current regulations.
The Mondex electric heater is suitable for use in a family sauna, one (1) heater per sauna
room. Retain the installation and operating instructions for further reference.
Always check the adequacy of the fire protection distances!
Failure to observe the wiring instructions may result in a risk of fire!
Always check the sauna room before switching the heater on!
Always check that the controller has switched the heater off after the set time period!
Due to the risk of fire, do not use the sauna to dry clothes or laundry.
Exercise caution with a hot heater, since the heater stones and metal parts become very hot
and can cause burns.
Steam from the heater is burning hot and may cause severe burns.
Children, disabled and ill persons who are using the sauna should be supervised.
Benches and floors may be slippery, therefore move in the sauna with caution.
Do not go to a hot sauna under the influence of narcotic substances (alcohol, drugs,
narcotics, etc.).
A stone compartment without stones or filled improperly will present a risk of fire!
Covering the heater will present a risk of fire.
To ensure safe use of the sauna, please read these safety instructions first!

Installation and Operating Instructions Kalla
1) Store the heater in its original package in an upright position and in
a warm and dry location until it is installed.
2) Inspect the heater visually. If you notice any discrepancies, please
contact the store where you purchased the heater or e-mail
info@mondex.fi.
3) The heater is installed so that it leans against a wall using the
bracket provided (see the dimensions on page 9).
4) To facilitate installation, adjust the heater’s feet so that they extend
out 8–9 cm.

Installation and Operating Instructions Kalla
Stacking the stones
Note! Use regular olivine diabase granite heater stones with a diameter of
less than 10 cm in the Kalla heater. Wear protective gloves when stacking
the stones. Stack the heater stones so that the resistors do not make
contact with each other. Do not bend the resistors so that they are in contact
with the metal structures of the heater.
Stack the stones in layers starting from the bottom. Stack stones loosely
to the centre of the heater and fit them more tightly against the metal net
frame. Continue stacking the stones in this way until all of them have been
placed.
Note! Ensure that the resistors do not touch the heater’s net frame
anywhere. There must always be a stone between a resistor and the frame.
Note! Do not remove the bands around the resistors. If there are two
bands, one of them is located at approximately 20 cm from the bottom and
another at approximately 10–15 from the top. They keep the resistors apart
from each other and prevent them from deteriorating prematurely.
Do not stack stones on top of the ventilation grill shown in the image – they
will block the heater ventilation!
Dents caused by the user are not covered by Mondex’s warranty or other
product liability. When stacking the stones, be careful not to dent the
heater’s metal surfaces to avoid damaging them.

5. General instructions for users of Kalla heaters
Note
Electrical connections may only be carried out by an electrician with valid installation authorization
according to the current regulations. The Kalla electric heater is suitable for use in a family sauna, one
(1) heater per sauna room. Retain the installation and operating instructions for further reference.
Installation cable
Use rubber cable H07RN-F as a connection cable.
Additional connection options
Control of electric heating with the heater: The electric heating control cable is brought directly
to the heater’s junction box and further to the heater’s terminal block with a rubber cable that is
dimensionally identical to the incoming cable.
NOTE! Failure to observe the connection instructions may result in a risk of fire!
NOTE! Remove all plastic film before using the heater!
6. Things to keep in mind when using the heater
First heating
During the first heating, the resistors may emit fumes. Therefore, ensure that the room is properly
ventilated. NOTE! Also see the first time use of E type on p. 14!
Sauna room
Always check the sauna room before switching the heater on! Always make sure that the timer has
switched the power off after the set time period!
Temperature control
The temperature is adjusted from the control panel (see page 14). The actual heating time depends on
the dimensions, structure and thermal insulation of the sauna. The temperature in the sauna room can
be maintained at the desired level with the thermostat. If the temperature of the sauna room becomes
dangerously high for any reason, the overheating protector will switch the heater’s power off. The
cause of overheating must always be investigated. The power can be switched on again by pressing the
overheating protector reset button (see page 14).
Heating time
An excessive heating time consumes energy and does not improve the steaming properties. The best
steam is achieved by keeping the sauna’s heating time relatively short, at about 30–60 min., according
to the size of the sauna and the heater’s power. The size of the sauna, the glass door, windows, or
materials used may require a longer heating time.
Water thrown onto the heater
We recommend using hand warm water. The water should be fresh household water. Throwing the
water onto the heater sides / lower stones generates softer steam. If you want steam that feels hotter
and more intense, pour plenty of warm water on top of the heater all at once.

Sauna room structure
The sauna and its ceiling, in particular, should have good thermal insulation, as heat tends to escape
through the ceiling. Due to the moisture, we recommend that you use aluminium paper. The size of the
heater should be selected according to the size of the sauna (in cubic metres). In addition to calculating
the power need for the regular sauna structure (glass wool–foil–wood), the following should be taken
into consideration. If the sauna has any uninsulated wood, tile or concrete surfaces or the walls are
made of logs, the heater power needs to be increased. For every uninsulated square metre, the heater
power need increases by the same amount as if increasing the space volume by 1.2 m3 and on timber
surfaces by 1.5 m3. The factor for glass surfaces (glass walls, doors and uninsulated stone surfaces) is
also 1.2 m3 per square metre. In borderline cases, you should choose a heater with higher power.
The sauna needs efficient ventilation for a good oxygen level and a sufficient amount of fresh air.
The air in the sauna needs to change at least 6 times per hour. For a sauna with an electric heater,
mechanical ventilation is the most convenient ventilation method. The supply air should be provided
through an inlet located 500 mm, at a minimum, above the heater, either on the wall or in the ceiling.
The exhaust valve should be placed on the opposite wall, as far away from the heater and as close to
the floor level as possible. It is highly recommendable to install an exhaust air valve in the ceiling as
well for an easier removal of moisture after sauna sessions.
For more information, refer to the construction instructions and building regulations.

Installation and Operating Instructions Kalla
When these minimum distances are adhered to, the recommended
safety distances between the heater and any inflammable materials on
the sides and underneath the heater are met.
Floor
Keep in mind that the adjustable feet may add to the total height of the
heater.
