2.7. If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:
- the power is on;
- the main fuses of the sauna heater are intact;
- is there any error messages on the control panel. In case of an error message on the control panel,
please refer to the control panel instructions.
THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE PREMISES
FOR THE FUTURE USER.
2.8. Preparing for sauna heater installation
Check the following before installing the sauna heater.
- The ratio of the heater's input (kW) and the sauna room's volume (m
3
). Volume recommendations are presented in
Table 1 on page 6. The minimum and maximum volumes must not be exceeded.
- The sauna room height must be a min. of 1900 mm.
- Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall surface
adds 1.2 m
3
to the sauna room's volume.
- Check page 8 Table 2 for a suitable fuse size (A) and the correct diameter of the power supply cable (mm²) for the
sauna heater in question.
- Conform to the specified safe clearance around the sauna heater. Please refer to page 6.
- There should be enough room around the control panel for maintenance purposes. Also a doorway can be considered
as a maintenance area.
2.9. Installation
Follow the safety clearance specifications on page 6 and 7 when installing the sauna heater.
The sauna heater is a floor-standing model. The base must be solid, because the sauna heater weighs about 120 kg.
The sauna heater is levelled by the adjustable legs.
The sauna heater is fixed on the floor from its legs by the provided metal fasteners (2 pcs). This will keep the safety clear-
ances intact during use.
Mounting of the sauna heater to the wall or the sauna benches available as an accessory (metal fastenings. S-ZH 58,
0043272).
Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they may
cause a fire hazard.
Only a single sauna heater is allowed per sauna room.
