Instructions for Use and Installation Helo Steam
The Sensor OLET 22 should be fitted about 1700 mm above the floor, ideally on the wall opposite the door. We
recommend sealing the sensor installation hole with appropriate sealing material, so that moisture cannot enter the
structures.
The steam room thermometer must installed at the height that gives the same reading as that shown on the control
panel.
The On/Off push button (accessories, External switch) can be used for starting and stopping of the steam
generator remotely. the push button is installed outside the steam room.. For more information about the control
panel and reception couplings, please refer to the user manual and the switch diagram.
Overheating protector
The steam generator is equipped with an overheating protector. If the protector has tripped, find the root cause with
the troubleshooting guide in the instruction manual. The overheating protector is reset by pushing a button.
NOTE: The overheating protector is located under the upper lid of the steam generator. Only a qualified electrician is
allowed to do this.
Main switch
There is a main switch at the bottom of the end of the steam generator, which should only be used when the steam
room will not be used for a long period of time.
The steam generator's automatic flushing and rinsing function will stop if the power is switched off. (Accessory,
Automatic drain valve)
Ventilation
There is usually no need to ensure ventilation of steam saunas that are used for less than two hours. Steam rooms
that are used for more than two hours at a time, on the other hand, do need ventilation for functional and hygienic
reasons. The recommended rate of ventilation is is 10–20 m³ per person per hour.
If there is an empty space above the ceiling of the steam room, it must not be completely sealed off. Make at least
one ventilation hole (100 mm x 100 mm) leading to the empty space, on the same wall as the door.
The supply air valve may be a hole in the bottom part of the wall with the door or a gap under the door.
The exhaust valve is place in the ceiling or on a wall near the ceiling as far from the supply air valve as possible,
however not above the door or the seats. The exhaust valve is connected to an air conditioning channel going
outside
Forced ventilation. If natural ventilation is not adequate (e.g. negative pressure in the room where the fresh air is
taken from), the steam room must be equipped with forced ventilation. Its output must be equivalent to 10–20 m³ of
ventilation per person per hour.
