The control panel includes a 3-meter heat-resistant cable, which can be extended to the outside of the sauna room by normal weak current cables.
Failure to follow these causes too high temperature and a fire hazard (Unit: mm).

Remark: 1. The upper screws must be fastened tight, theminimumdistances between screw head and wall is 3mm.
Remark: 2. The wall behind the heater cannot be covered by materials like asbestos cement, asbestos board and so on, because this covering layer could cause high temperatures and a risk of burn.

SPECIFICATIONS

INSTALLATION OF TEMPERATURE SENSOR

1. Carefully unload the low cover at the neck position by the edge of the circuit board with a screwdriver.

2. Fasten the circuit board with the bolt to the wall straight over the sauna heater. Check the diagram for the minimum distance (See Fig. 3).

3. Fix the cover to the temperature sensor.
LIMIT CONTROL
Fitted as a safety feature is an overheating controller that prevents the heater from operating in case of a fault, such as a problem with the thermostat.
Should the sauna room temperature reach too high, the spare link in the sensor unit automatically cuts off the electricity.
The spare link will automatically return to its position when the temperature returns to normal.

GUARD RAIL
Please follow the minimum distance requirements in Figure 6 if a guardrail is desired for the heater.

OPERATION OF CONTROL PANEL
The control panel is splash-proof and can be installed in a sauna room. The temperature sensor unit must be installed on the wall inside the sauna room.
Please follow the minimum safety distance of the sauna heater during installation(See fig3), which is included in the installation diagram.
Failure to follow these may cause a burn to the wooden wall.

SAUNA ROCKS
After installing the sauna heater and controller, load sufficient sauna rocks(10-15kg) into the sauna heater.
ATTENTION: Sauna rocks must be of best quality because the temperature inside sauna heater is exceptionally high. Rocks of inferior cant withstand heat and they may be easily broken or crumble because of the huge heat changes, which may damage heating elements.
Or these stones may counteract the heat circulation because they are easily oxidized, the sauna heater may be damaged while the stone is being poured with water to make vapors.
VENTILATION
To have a soothing sauna bath, there should be a proper mixing of hot and cold air inside the sauna room. Another reason for ventilation is to draw air around the sauna heater and move the heat to the farthest part sauna room. The inlet vent with a more than 6cm diameter should be installed directly below the sauna heater. (See fig 5)
The outlet vent should be installed diagonally opposite the inlet; it is suggested that it be placed under the platform inside the sauna room as far as possible from the inlet vent. The diameter of outlet vent should be twice as big as the inlet, it may be installed far away from the floor and under the bottom of the upper bench.
