OC-S Steam on Demand Switch

When the switch is operated the LED indicator inside the switch turns red and steam is generated for 30 minutes. At the end of 30 minutes or if the switch is operated again, the light will go off and the steam will stop. (Notice: Long Press the “Drain/Model” button for 5 seonds, the time display will show ”Long”, then enter “OC-S” mode).

Commercial Mode Instruction (OC-B+OC-S ) 

If OC-B is under domestic model, only the OC-B controls the steam generator .OC-S will not work. When OC-B is used on commercial model, the steam generator will be under waiting status (the time window shows “Long” and on circuit board the LED will be flashing) , press OC-S to operate steam generator , every press will make the steam generator keep working for intervals of 30 minutes , the temperature control will depend on the OC-B controller’s setting.


Steam Room Design

As a guide; For lightweight materials such as plastics and laminates, 1 kW will heat up to 3 1m of air. For dense materials such as stones and ceramics which conduct heat more 3 rapidly allow for up to 2kW per m of air. Hot air rises so restricting the height to around 2 meters will ensure the user is sitting in the steam. For higher ceilings, ensure to increase the power requirement.

If greater power is required one OC-B controller may be used to control two or more steam generators, e.g. if a 30kW steam generator is needed, one OC-B controller can control two 15kW steam generator or three 10 kW steam generators .

  2. Open the water inlet valve and water will enter the boiler, the indicator LED turns red. When the water level rises to the low water sensor level the elements will switch on and the heating indicator LED will turn on. When the high water sensor is reached the water inlet indicator LED changes to green and the water inlet valve will turn off.
  3. After a few minutes of operation the generator will begin steaming, for small steam generator 2-3 minutes and about 3-5 minutes for larger generators.
  4. Press of "Sinthani Chizindikiro “, key again and the controller turns off. The display turns off and steam stops being generated there will also be no data on display.
  5. Press of "Sinthani Chizindikiro “ key once more (temp and time display again) after a few seconds the generator will begin producing steam again. Let the generator operate for a short while until the water level falls to the low water level, check that the water inlet valve opens automatically and the water inlet indicator LED turns red. Cold water then enters the boiler and the steam generator starts to produce steam once the high water level is reached. The water inlet valve will close and the LED will turn green.
  6. The timer will then count down to show the remaining time and when it reaches 0 the steam generator will stop.
  7. Once the steam generator has operated for 10 minutes or more and turns off (manually or automatically) it prepares for automatic drain down cycle. Once the 0 temperature of the water falls below 80 C, drain and flush are carried out and steaming can begin.
    Onani Chizindikiro The water will only start draining once the temperature has fallen below 80 ℃. 
  8. " batani lantchito“This button has 2 functions; if the generator is off this button can be used to drain the generator manually. If the generator is switched on it can be used to select the steam on demand operating mode.
  9. When the preset temperature for the steam room is reached 2 of the 3 elements will switch off allowing just 1 to continue heating to maintain the temperature. Elements will cycle on and off to maintain the temperature to within approximately 2.5 degrees above or below the preset requirement.
  10. Boil dry protection – If the water supply is discontinued the water level indicator LED turns red and the steam generator stops immediately.

The single biggest problem with steam generation is the build up of scale resulting from dissolved solids within the water. Scaling can cause the elements to fail, the water level sensors not to function and premature failure of the O-rings resulting in leaksfrom around the elements. The extent of the problem will vary according to the degree of hardness in the local water supply.

It is recommended to use water softener. 

All commercial and domestic uses must ensure a regular maintenance routine for descaling the generator. The frequency of this will vary according to the degree of hardness in the local water supply and the amount of time the generator is used. Check the water for hardness and arrange the descaling routine accordingly.

Faults arising from a failure to descale the generator are not covered by warranty. 

Because heating and cooling cause expansion and contraction it is important to inspect all the water and steam inlets and outlets as well as their pipes and connectors on a regular basis to ensure there are no leaks.

Clean the filter net in the magnetic valve according to the water quality in the location.

Wiring and electrical integrity of the generator should be checked regularly at least once a year.
