Heater Stones; Loading Stones Into The Heater - Sawotec 3P-1P Bedienungsanleitung

Heater Stones

The main purpose of the stones in the heater unit is to store enough energy to efficiently
vaporize the water thrown on top of the stones to maintain correct humidity in the sauna room.
The stones must be replaced at least once a year or every 500 hours which ever occurs first. All
stone crumbles must be removed from the heater unit and replaced with new ones as
described in the heater manual. The required amount of stones is also listed in the manual
provided. See page 22 (Technical Data).
NOTE! Never use the heater without stones as it may cause fire or damage the heater. In
household use recommended stones are Olivine, olivine diabase or peridot in size less than 10
cm. Stones must be loaded into heater so that there are space between stones for air
circulation.

Loading stones into the heater

It is recommended that all stones should be rinsed to remove any stains or dust that
can cause unpleasant odor during the first few times of using the heater. It is
important that the stones are loaded carefully in a way that they do not block air
circulation through the heater. Load the stones to the heater so that the heating
elements are not visible from any angle. Make sure that the elements don't get
bended or touch each other as a result of the loading by properly installing the
heating element spacer. Larger stones that won't fit between the heating elements
must not be forced in place instead they must be completely removed. Small crumble
or stone pieces smaller than 35mm in diameter must not be loaded into the heater
because they will block the air circulation and will cause overheating and possible
heating element damage. Use the addtional heating element separator to make sure
that heating elements are in no contact with each other. Do not place stones inside
the heating element holder, but only around and on top of it. If heating elements
touch each others, it will significantly reduce the life span of heating element.
NOTE! Heating element damage due to overheating caused by wrong kind of stones
or stones which were wrongly loaded into the heater is not covered by the factory
warranty.
Before the heater is filled with stones, electrician should test that the heater works.
Testing can be done by turning on the heater for a short time without any stones and
verifying that all heating elements are heating up.
