Instructions for use and installation
INSTALLATION OF THE SAUNA HEATER IN THE SAUNA
These sauna heater models are installed freestanding and fixed on the floor from two legs with cotter bolts.
When fixing the sauna heater, adhere to the minimum distances from flammable surfaces as specified in the sauna heater's
rating plate. The sauna heater can be installed on a wooden floor. The walls behind the sauna heater or the ceiling must not
be clad with fibre concrete board, for example, because it may result in an excessive rise in temperature of the wall material.
The sauna heater must not be installed in a recess or surrounded by enclosed covering. Wooden panels can be used as
wall and ceiling material. A single sauna heater is allowed per sauna room.
INSTALLATION OF THE CONTROL CENTRE
The control centre is installed outside the sauna in a dry space. The sensor is attached to the sauna wall as specified in
Image 1. Any deviation from the given measurements constitutes a fire hazard. Any draft from the door, valves, etc. has a
negative impact on the thermostat and should be avoided.
The following control centres are compatible with the sauna heater:
•
1410 – 33 – 1517
•
1410 – 33 – 1517 -3
•
1410 – 33 – 1519
•
1601 – 12 and 2005 - 4
•
1601 – 13 and 2005 - 4
•
2005 – 6
Detailed operating instructors are available in the specific operating instructions for each control centre model.
SAFETY RAIL
If a safety rail is installed, it must adhere to the minimum distances specified in Table 1. The safety rail must not be
enclosed.
SENSOR
The sensor is placed on the centre line of the sauna heater in accordance with the measurements specified in Image 1. The
sensor is equipped with a 5m heat-proof (T 170°C) 4 x 0.25mm
wire (with a similar cross-section).
ELECTRICAL INSTALLATION
Only a qualified electrician should connect the sauna heater and the control centre to the electrical power network
in accordance with the current regulations. The necessary connection diagrams are available inside the sauna heater and
the control centre and at the end of the operating instructions. The sauna heater must be connected semi-permanently with
medium-duty, or stronger, rubber cable H07RN-F (60245 IEC 66), see Table 1.
NOTE:. Do not use PVC insulated connection cable, which is prone to thermal embrittlement.
The connection box must be splash-proof and it must have a draining device. The height of connection box measured from
the floor must not exceed 500mm. If connection or installation cables are mounted on or inside the sauna wall at the height
of over 1,000mm from the floor they must resist at least 170°C when loaded (e.g. SSJ).
Electrical devices installed over 1,000mm from the floor must be approved for use in ambient temperatures over 125°C (T
125 marking).
Installing the sensor near a supply air vent
The sauna room air should be exchanged six times in an hour. The diameter
of the supply air pipe should be between 50 and 100 mm.
A circular air supply vent (360°) must be installed at least 1000 mm away
from the sensor.
An air supply vent with a flow-directing panel (180°) must be installed at
least 500 mm away from the sensor. Air flow must be directed away from
the sensor.
