Sensor Location if heater is powered with SAWO Control

SAWO Control Unit utilizes two sensors to power up the Combi heater. One is the Primary Temperature
•
Sensor (TS1) and the other one is either the Secondary Temperature Sensor (TS2) or the Temperature
and Humidity Sensor (T/H). If the heater is placed less than 200 mm from the wall, TS1 needs to be
mounted on the wall above the heater and must have a distance of 150 mm from the ceiling. However,
if the heater is placed more than 200mm from the wall, TS1 must be mounted to the ceiling over the
heater, as shown in the illustration. TS2 or T/H should be mounted on the wall opposite to the heater
and must have a distance between 300mm from the ceiling up to 1300mm from the floor.
2.2.6 Effect of Moisture During Transport and Storage
When doing a final inspection for the electrical installation of the Combi Heater, a "leakage" may be
•
detected when measuring the insulation resistance. This is because the insulating material of the
heating resistors has absorbed moisture from the air (during transport and storage). The moisture will
eventually be removed after several uses of the heater.

How to Load the Stones?

•
Stones are loaded into the Combi Heater so that enough energy will be stored to efficiently
vaporize the water thrown on them and maintain the correct humidity inside the Sauna Room.
•
These stones must be replaced at least once a year or every 500 hours, whichever, occurs first.
•
In removing the stones, stone crumbles (small pieces of stones that has broken off from the larger
ones due to frequent usage) must be removed as well.
•
Refer to the Technical Data in Figure 11 for the required amount of stones.
NOTE: Never use the Combi Heater without the stones as it can cause fire. Use only stones
recommended by SAWO. The use of any other kind of stones may damage the heating elements
and will void your warranty. Also, never use ceramic stones or any other artificial stones.
•
Before loading the stones into the Combi Heater, rinse them first to remove stains or dust that may
emit unpleasant smell when using the unit for the first time.
•
Care must be taken in loading the stones and make sure that they will not block the air circulation
through the heater. Refer to Figure 8.
