4. USE AND MAINTENANCE OF THE HEATER
WARNINGS: The Kastor heater is intended for heating a family sauna to normal sauna temperatures, and it
must not be used for any other purpose. The sauna room must be checked before the heater is switched on.
Beware the hot heater, as its stones and metal parts may scald your skin at operating temperatures. Care is
mandated in the heater's vicinity as well – particularly due to the danger of slipping. During water throwing, you
should watch the hot drops spraying from the stones and the hot steam. Parents must watch small children in the
sauna and make sure instructions are heeded. The heater's controls must not be touched immediately after water
throwing (because of the hot steam rising from it). You must not throw too much water on the heater at a single
throw to prevent dangers from excessive amounts of steam. The heater must not be covered and it must not be
used without stones. Unhindered air flow must be ensured particularly behind the heater. You may not hang
inflammable objects such as clothes or carpets above or near the heater, as that is a fire hazard. This heater has
not been designed for use with sea water. Only one heater may be installed in any single sauna room. Check that
the heater is attached properly before heating it. after the heating period, make sure that the heater's timer has
turned off the electricity at the set time. If you have any problems or questions during the warranty period, please
contact the manufacturer before performing any repairs. Use gloves during maintenance and cleaning work to
protect your hands. Remove any unnecessary stickers and plastic packaging prior to first use!
4.1. The Heater Stones
The heater must not be used without heater stones. We recommend the use of traditional quarried heater stones
(e.g. peridotite or olivine). A suitable stone size for electric sauna heaters is 5-10 cm. If you want moist and long
lasting results from a water throw, you may use a few soap stones in the mix. These go to the bottom of the stone
basket. The stones must be washed with a brush before they are put into place. You should check the condition of
the stones at least twice a year. Gravel dropping from the stone basket is a sign of abrading stones.
4.2. Filling The Stone Basket
The innermost part of the stone basket should be filled with bigger stones, right up to the surface layer. Use
smaller stones at the upper part, going towards the edges.
Take care that no stones fall through the supports onto the heating coils, as the impact may destroy the coils
before their time. The stones must not rise more than 1 cm above the edge of the heater. If the upper stones
remain often wet, you have too many stones or they are too small.
4.3. First Heating
The first heating is performed at maximum temperature with good ventilation. This burns any contaminations off
the stones and the coils, which may produce some smoke.
4.4. The Sauna's Preheating Phase
The preheating phase means the time needed for heating the sauna room to the desired bathing temperature. The
time required depends on the desired temperature (position of temperature switch), the amount of stones in the
heater, the room's volume and surface material. The fewer stones you use, the quicker the room heats up, but a
smaller amount of stones gives a less satisfying steam output. The preheating phase lasts usually between 40 and
70 minutes.
4.5. Using The Heater
The heater is used from its control panel.
