SENSOR PROBE REMOVAL FOR DIRECT CLEANING
Make sure the power is shut off at the circuit breaker. The water level sensor probe is located on top of the steam
generator tank. You need to remove the cover of the steam generator, next locate the large transformer, near it should be
a hole with three wires going into it and attached to tabs. That is the water level sensor. Older units have a ceramic sensor.
The newer units have a two-piece sensor, a nylon threaded ring and a red rubber center. The electrical connections are
the same, the sensor removal is slightly different. Note the color of the attached wires and the polarity of the tab they are
attached to. Unplug the wires and unscrew the sensor. The newer two-piece sensor requires you to unscrew the ring then
pull the red plug up to expose the sensor probes. Make sure there is no scale or debris on any of the three probes.
Reverse the above procedure to reinstall the sensor.
If needed the probe connections are as follows
Red wire connects to the shortest probe and is the positive wire ( + )
Yellow wire connects to the middle length probe and is the negative wire ( - )
Black wire connects to the longest probe and is the Ground wire.
CHOOSING PROPER LOCATION
Recommended locations for proper installation:
1. The steam box should not be located further than 16 feet away from the steam room.
2. The steam generator should not be installed in the steam room.
3. The steam generator should not be installed outdoors or in any place that will influence the security of the machine.
4. Do not install in any place where the water might freeze.
5. Do not install near flammable objects or chemicals (coal, gas, etc.)
6. The steam generator should be installed in a dry and ventilated place.
7. Make sure the steam generator is secured on the wall and is horizontally positioned.
8. On the other three sides, there has to be at least 6 inches of space left between steam generator and any other object.
9. The place where the machine is installed must be accessible for cleaning and possible service work.
10. The steam generator should be in close proximity to a drain for convenient Water Drain Valve hook-up.
11. After use, the steam pipe, safety valve, drain valve, water pipe, steam outlet is still very hot.
12. Place steam outlet away from bathers.
Attention: install an exhaust fan outside of the steam room so that it can expel any excess steam for proper ventilation.
13. The shorter and straighter the steam lines, the more efficient they will be.
14. The unit should be slightly higher than the steam outlet to allow condensation to drain out of the steam head.
15. Avoid using 90-degree fitting. Use 45-degree bends to allow better steam flow.
16. The steam line must be insulated.
