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.

INSTALLATION

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 .

Installation Instruction

The OC-B controller has a working window of 10-240 minutes and 30-60 C. When the time is not set, the generator operates continuously until switched off.

An O-S demand switch may be included in the controller to set working times in regular intervals of 30minutes

Equipment Installation

The steam generator should be installed in a dry well ventilated place in close proximity to the steam room. It can be placed on the floor or hung from a wall.

Installation Instruction

To hang the generator on a wall drill 3 holes 8mm in diameter as below image and use the wall plugs and screws provided.
Fix the top 2 screws in place first then hang the generator by the 2 keyhole shaped holes in the back plate.
Then with the front cover removed fix the third screw to secure the unit in place.

Water & Steam Connection

The water supply pipe and steam pipe should comply with local standards.
Connect the water inlet valve of the generator to the 15mm mains water supply using a flexible hose with 1/2 inch fittings.
Steam outlet (1/2 inch or 3/4 inch) should use the same dimension copper pipe for ease of connection
According to the location it may be necessary to attach an additional length of pipe to the pressure relief valve in order to divert the steam flow to a safe direction should the valve operate.
Connect the drain outlet to a suitable drain via a copper pipe with the appropriate fittings.
Make a secure connection between steam nozzle & steam pipe.
Use non corrosive hose with ½ inch unions to connect between the descaling liquid container and the inlet valve; note the descaling liquid container must be mounted at least 500 mm above the steam generator.

Installation of Controller and Temperature Probe

Steam generator controller is water proof and can be installed inside or outside the steam room according to customer preference.

The control panel should be installed at a height of approximately 1200mmm for ease of use.
To Install: drill a Φ40mm hole on wall. Open the front cover of steam generator. Fix the control cable (6 core) and temperature sensor cable (2 cores) to the relevant ports. Put the protruding back of controller in the hole at the bottom of controller press close to the wall and place back the cover.
Control panel installation: Screw one end to circuit board ports in steam generator and connect the other to the controller’s cable.

Temperature probe installation: The temperature probe is installed inside the steam room at approximately 1.2 to 1.5 meters high and away from the door respective. Use a Φ4mm screw to fix it in place and connect to the wire from the controller.

Installation for Power Supply and Control Cable

Confirm the correct voltage of power supply and the wires.
Remove the knock out for the power cable entry and use a rubber grommet to protect the cable, connect the conductors to the correct terminals. For single phase power use the copper bridge connectors.
Ensure the power supply wire and control cable remains separated to prevent magnetic field of power supply wire from interfering with control cable signal.

Steam on Demand Function

Commercial operators may wish to take advantage of the steam on demand function which allows bathers to press the steam on demand button located inside the steam room after which the generator will operate for 30 minutes then stop until activated again. To operate the steam on demand function install the controller inside the plant room alongside the generator then fit the push button supplied in a convenient location inside the steam room and connect to the controller with the cable provided.

OPERATION

Steaming Control

Once the installation has been completed and checked, turn on the power and water supply and carry out the following procedure

On the control panel press the “ ****“ key , the key has a time-lapse function, long press for 1 second, the time and temp windows will display the data.
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.
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.
Press the “ ****“, key again and the controller turns off. The display turns off and steam stops being generated there will also be no data on display.
Press the “ ****“ 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.
The timer will then count down to show the remaining time and when it reaches 0 the steam generator will stop.
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.
The water will only start draining once the temperature has fallen below 80 ℃.
“ ****“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.
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.
Boil dry protection – If the water supply is discontinued the water level indicator LED turns red and the steam generator stops immediately.
The “ ****“ button can output AC230V to power the transformer for a 12V steam
room lamp. Drain Model Light
“ __“ button has 2 functions; it can be used to power a fan if fitted and can also be used during the temperature or time setting procedure to confirm the settings (see further details below).
“ ****“ button has 2 functions; it is used to set the time and temperature settings and to start the descaling operation (see further details below).
The display temperature can be changed from Celsius (default) to Fahrenheit by altering the settings of the JP1 pins on the circuit board.

Setting Time and Temperature

The steam generator default settings are 40 C temp and 1 hour of operation which can be adjusted as follows;

To Clean set time: press “ “ key and the time display window will flash – press “ “ or “ **“ to adjust the time, every press increases or reduces by 5 minutes, once the desired setting is achieved press “ __**“ the window will stop flashing. Time may be adjusted from 10 to 240 minutes. Exceeding 240 minutes the display will show “NO” meaning no time limit.
To set temperature press “ “ twice. The temperature window will flash, enter the required temperature by pressing “ “ or “ **“ to adjust – every press will increase or reduce by 1 ℃ . Temperature is adjustable from 30℃-60℃ , press “ __“ key and the window will stop flashing.
The memory is lost and reverted back to the factory default settings when the power is cut off.**
Auto-descaling can only operate when the steam generator is in OFF mode i.e. the boiler has finished steaming; the water has drained and flushed, the drain LED will be off. Before auto-descaling can commence, a supply of dilute citric acid liquid must be connected from a storage vessel positioned at least 500mm above the steam generator. For the dilution ratio refer to the information supplied with the citric acid.

Descaling Process

Do not use strong acids or high concentrations as these may attack and destroy the element or other metal parts of the boiler.

To start the process press the “ ****“ key for 5 seconds, “Clean” LED light will come on and time window display last setting time (default setting is 8 hours).
Press “ “ or “ “ for 5 seconds, to change display into hours, increase or decrease to set the required time, each button press will increase or decrease 1 hour, maximum is 24 hours, minimum is 1 hour.
Once the setting is done the flashing will stop and the process will begin automatically by opening, the inlet valve for the boiler to fill with the descaling solution. The inlet valve will then close and the solution will remain inside the boiler for the preset time.

Flushing and Draining

At the end of the sequence, the drain valve will open and the boiler will drain and then flush with clean water; when the cycle is complete the drain LED will go off.
Ensure there is sufficient descaling solution in the container to completely fill the boiler – when liquid level reaches set point , the LED on circuit board will light up.
If during descaling the power supply is interrupted do not operate the steam generator until either the descaling process has been reset or the acid solution has been drained and the boiler flushed with clean water – minimum 3 flushes.

MAINTENANCE

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.
