Maintenance
The unit will drain automatically 20 minutes after use.
Clean the steam generator every 60 uses, and 30 if on well water.
1. Wait for the completion of automatic water discharge after each use of the steam engine to make sure the
water in the tank is discharged completely before cutting off power supply.
2. There should not be any leaking or damage to the steam engine, steam nozzle, components and pipes. They
should be checked monthly.
3. Clean the water supply pipes of the steam engine once a year.
4. Check all the connections, water, and electric, to see if they have become loose or are damaged due to
overheating.
Steam Generator Cleaning
MAKE SURE POWER IS OFF
IF you can observe that the steam generator is draining after use, this means the tank is not clogged with debris or other
material from use. The tank cleaning procedure is not too difficult.
You have to introduce the citric acid solution in to the tank. The 6 and 9 Kw units have a 1.5-gal tank, the 12Kw has a 3.2-
gal tank. Mix 1 ½ cup of citric acid powder to about 20 oz of warm water. Dissolve the powder and pour it into the tank.
This can be done by disconnecting the steam line and with a funnel and hose pour the solution into the tank. If the
steam line cannot be disconnected you can unscrew the pressure relief valve and pour the solution in through the
opening. Both openings go the tank. Replace the steam line or the pressure relief valve, then turn on the steam
generator on and let it produce steam for about one minute, then shut it off at the circuit breaker and let sit for an hour
or two or overnight for a thorough cleaning, it will not hurt anything. Then restart the generator and let it run for about
5 minutes and shut it off at the key pad and wait until the automatic drain allows the solution to exit the tank or use the
manual drain button on the key pad. When you restart the generator, you hear water going into the tank when you
turned the unit on, it indicates the tank was empty, so you know the drain is not clogged. Once again it is most
important you are able to actually verify the solution has been drained out from the unit. By verifying the draining of the
solution, you know the tank is not clogged. If the tank is clogged it leads to premature heating element failure and other
issues. This procedure will also clean the water level sensor probe.

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.
