Instructions for Use and Installation HNS-M / HLS
Use and installation
HNS-M and HLS steam generators are only intended for use in heating spa facilities. Using steam generators in other
areas than steam rooms can damage the building's structure.
The manufacturer is not responsible for damages caused if the unit has been used incorrectly or in a manner for
which the unit was not designed for.
Water and steam pipe connections must be made prior to connecting the unit into the mains.
Due care and attention must be taken when making the connections. Proper sealing must be ensured for all
extensions. A good extension must have at least taped over twist connections, but it is recommended that
connections are soldered.
The steam generator must be placed away from water and moisture (dry room). The room must be airy as the unit
also produces heat. The maximum recommended ambient temperature is 25°C. The minimum recommended free
space to the sides and above the steamer is 30cm. Adequate space for maintenance should also be planned for in
the placement of the unit.
There should be a drain nearby for draining the tank.
The steam generator can be installed freestanding on the floor or on the wall using wall fittings. When using wall
fittings, ensure you use appropriate fittings and screws for the type of construction material of your walls. The steam
generator weighs about 17 kg when filled with water.
When the automatic drain valve is used, it is recommended you use wall installation so an adequate angle can be
ensured for draining of water.

Locating the control panel
The control panel may also be installed in the steam room, model HNS – M.
HSX-L Roma centre is only to be installed outside the steam room.
NOTE: The RA 17 control panel has a built-in thermostat. If an external thermostat is used, the cable is connected to
steamer circuit board in model HNS – M. In other models, the thermostat cable is connected to the control centre,
model HLS (Roma I and Roma II)
The cable can be extended with a similar cable, also for control panel, max. 10m.
Steam nozzle / nozzles are fitted approximately 200 – 400mm from the floor underneath a bench or a seat, or onto
the wall so that the hot steam cannot burn anyone's feet. The steam nozzles are aimed towards the floor. When the
nozzles are installed, you must ensure to place them somewhere where nobody can accidentally touch them. The
steam temperature is +100 °C and it can cause injuries on contact.
The thermostat is installed at about 1700mm height, preferably on the wall opposite the door. It is recommended to
seal the thermostat installation hole with appropriate sealing material, so that moisture cannot enter the structures.
