Instruction manual | Float electric heater Page 3
Installation of the heater
1. Check that all the required items are included in the delivery. (See page 2: Content of delivery)
2. Select the location for the heater to be installed in, following the proper safety distances (Page 7).
3. Take into consideration the location of air vents, thermostat (page 5) and control unit (Ref. the
separate installation instructions for the control unit).
4. Lift off the outer casing to reveal the base unit and the heating elements (installation image 1).
5. Open the bottom plate of the base unit under the heater (installation image 2).
6. Make the electrical connections according to the circuit diagram on page 6. Note!Leave the
powercables (2 pcs. 5x2,5mm) leading off the box long enough to allow for the installation to be
performed above the lower bench.
7. Connect the heater to control unit according to the separate instructions in the control unit box.
8. After alle the connections are made, test that all heating elements are functioning properly by
switching the power on. If all the elements are working, close the base plate. if one or more of the
heating elements fail to heat up, or there is another problem, such as a fuse blowing, contact the
manufacturer.
9. Install the heater base in the hole made in the flooring (installation image 3).
10. Place the integration collar around the hole on the lower bench (installation image 4).
11. Install the heater’s outer casing on top of the base making sure the grooves in the casing and the
electric cords fit together (installation image 5 and 6). Level the heater securely before laying in
the stones.
12. LAYING THE STONES: We recommend using KERKES ceramic interspace sauna stones around the
heating elements. The specially designed Kerkes stones support and protect the heating elements,
and they do not disintegrate prematurely. As surface stones, we recommend rough cut olivine,
olivine diabase or peridotite (e.g. Parhaat Löylyt) stones the size of 5 to 10 cm in diameter. Lay the
stones carefully, making sure there is room for air to flow freely around the stones. Make sure to
lay the stones so that the heating elements DO NOT touch one another, or the outer casing. NOTE!
Soapstone, rounded stones or natural stones may only be used at the surface level.
13. IKI-Kiuas recommends, for safety reasons, to build a safety railing around the heater if the heater is
in public or semipublic use.
14. As the stones settle down, when used, the surface will drop down a little. Add more stones, if
needed. The frequency with which the stones should be replaced depends on stone quality and
frequency of sauna use. Check the condition of the stones yearly, remove any broken ones and
replace them with new ones. Normally it is recommended to replace all the stones at once.
Installation of lighting:
1. Take the heater light’s white cable and connect the positive (+) brown wire and negative (–) yellow
wire and attach them to the corresponding terminal in the dimmer unit LL1-CV-SC (installation
images 7 and 8).
2. Connect the 230V supply voltage to the black connection box’s Wago connectors, L = 230V and N=
neutral 0 wire (installation image 9).
3. Install the Gira dimmer switch onto a wall according to the instruction on page 8. The dimmer
switch has been pre-paired with the receiver. When you touch the switch briefly, the lights go on
and off. Pressing the switch longer will dim and brighten the lights. Indoors, the operating range of
the dimmer switch is 30 metres. If installed inside the sauna room, the dimmer switch should be no
closer than 1000 mm to the heater and below the height of 1000 mm.
4. The dimmer unit, light’s adaptor and connection box should all be installed in a dry space.

Connecting the heater to electricity
The heater is connected to the electric supply with a H07RN-F, or similar, rubber cable. The use of PVC-
insulated cables is forbidden due to poor heat resistance. The electrical installation must be performed by
a licenced electrician and must adhere to current legislation. The cable must be installed safely away from
mechanical strain and heat radiation. If the rubber cable runs inside the wall panelling 1000 mm above the
floor rom it will need to be heat resistant up to 170 degrees Celsius (e.g. SSJ).
Control unit
For installation, refer to the separate installation instructions specific to the control unit.
Sauna’s temperature sensor and overheating fuse
Sensor location:
INSTALLATION TO THE CEILING:
- 10-30 cm from the outer casing of the heater.
INSTALLATION TO THE WALL:
- 10 cm from the ceiling
- 10-30 cm from the outer casing of the heater.
Note!
Make sure the temperature sensor is not located less than 1000 mm distance from un undirected air inlet
vent, or less than 500 mm from a vent that is directing air away from the sensor.
Temperature limiter will switch off the power from the heater if the temperature in the sauna raises
dangerously high (139) due to a malfunction.

Electrical two-way switch connection:
If the control unit requires an additional contactor, we recommend a two-way switch connection to
distribute the power evenly to the control unit and the additional contactor.

Instructions for use
•Before bathing for the first time, heat up the heater once to burn off protective oil solvents. Air out
the sauna room efficiently afterwards.
•The heating time is about 45–75 minutes depending on the size of the room and its ventilation.
Recommended bathing temperature with IKI heaters is 50–70 degrees. Pouring water on the stones
increases the temperature and humidity.
•Set the desired temperature from the control unit.
•Check that the heating elements do not become exposed as the stones shift about due to heat
•expansion.
•Check the condition of the stones once a year, and clean and replace as necessary.
•Do not throw water onto the heater when there are people close-by: the steam is burning hot. Do
not throw too much water on to the heater. Maximum amount is half a litre at a time.
Troubleshooting
If the heater fails to heat up, check that
•Electricity has been wired properly
•Fuses are intact
•Timer switch is set to i.e 1-4 h, for heating
•The thermostat is set to a higher temperature than current room temperature
•The overheating fuse has not gone off. If it has, the reason must be resolved before attempting to
re-heat the heater.
•The stones are laid correctly.
If you find discoloration in the wooden structures near the heater, check that the safety distances are
followed correctly, that the stones have been laid correctly and the heating elements are not exposed or
touching one another. The heat radiation from exposed resistors is extreme.

on the wall or the ceiling at about 500 mm above the heater. The supply air inlet vent should be 50-100 mm
in diameter. The outlet vent should be located as far away from the heater as possible, close to the floor.
The outlet vent should be twice the size of the inlet vent.
NOTE!
The thermostat sensor should be installed minimum of 1000 mm distance from an undirected supply air
vent or at least 500 mm away from a vent directing air towards the sensor.
