• Stones with a diameter of 2-4 in (5–10 cm) are suitable for the
heater.
• The stones on the external surface of the heater must fully cover
the heating elements. The heating elements must not be visible.
• The external surface of the stone container must be stacked full
as tightly as possible; the surface of the heating elements must
not be visible.
• Using ceramic stones in the DROP heater is allowed upon the
user’s responsibility.
ATTENTION!
A TOO SPARSELY FILLED STONE CONTAINER CAUSES FIRE HAZARD!
Before switching the heater on, the insulation resistance might prove
to be lower than the standard.
The reason for that is the moisture seeped into the insulating layer
during storage in the warehouse and transportation. The moisture
evaporates in 1–2 hours of heating the electric heater.
Controlling the heater
The output of the heater must remain in the interval determined by
the control panel’s producer. Product other than those for installation
in public saunas, shall be provided with a timer. For appliances for
use in blocks of flats, hotels and similar locations, the operating
period of the sauna heater shall be limited to 12 h with a minimum rest
period of 6 h before any automatic restarting. For other appliances,
the operating period of the timer shall be limited to 6 h, automatic
restarting not being allowed.
